Este trabalho tem como objetivo a avaliação do desempenho de combustíveis para motores ciclo Diesel, emissões de contaminantes e tratamento catalítico pós-combustão, em condições reais de operação. Para obtenção de resultados relativos ao consumo específico de combustível e geração de contaminantes atmosféricos, utilizaram-se motores Diesel, monocilindro, de pequeno porte, acoplados a geradores elétricos. A partir dos resultados obtidos neste trabalho, constatou-se que é possível a obtenção de parâmetros relativos ao desempenho, emissões de contaminantes e tratamento catalítico pós-combustão utilizando motores/geradores e um procedimento específico de amostragem. Os resultados indicaram que o consumo específico do óleo diesel, biodiesel e formulações apresenta uma correlação direta com a entalpia de combustão. A quantificação dos contaminantes é altamente dependente do procedimento de amostragem utilizado, do tipo de motor e das condições de operação empregadas. A redução das emissões de material particulado (MP) com a utilização de biodiesel é controversa. Com motor de alta taxa de compresssão e maior pressão de injeção não se observa uma redução significativa nas emissões de MP, quando o motor é alimentado com biodiesel. A adição de biodiesel etílico de soja, em formulação com óleo diesel, aumenta a concentração de NO. Comparado com o óleo diesel, o biodiesel aumenta em 16% as emissões de NO. Este aumento não está associado às características de volatilidade e viscosidade do biodiesel, mas sim, à sua compressibilidade. A utilização de catalisador com platina possibilita a oxidação das frações voláteis e condensáveis da exaustão do motor. O catalisador de platina não apresenta atividade de oxidação da fração seca que compõe o MP. O NO2 é reduzido para NO através da oxidação dos hidrocarbonetos voláteis e condensáveis e não se observa redução dos NOx para N2.

An evaluation was made of the performance of fuels for Diesel cycle engines, their contaminant emissions and catalytic post-combustion treatment under real operating conditions. The findings concerning specific fuel consumption and production of air pollutants were obtained using small single cylinder Diesel engines coupled to electric generators. The results of this study indicated that it is possible to obtain parameters relating to performance, contaminant emissions and catalytic post-combustion treatment using engines and generators and a specific sampling procedure. The results also indicated that the specific consumption of diesel oil, biodiesel and formulations is directly correlated with the enthalpy of combustion. The quantification of the contaminants is highly dependent on the sampling procedure employed, on the type of engine and on the operating conditions employed. The reduction of particulate matter (PM) emissions with the use of biodiesel is a controversial point. With a high compression engine and greater injection pressure, no significant reduction in the emission of PM has been observed using biodiesel. The addition of soy biodiesel in…

▼ Microscale reactors operate in sub millimeter space dimensions. Their small length scale enables process intensification of mass, heat and momentum transport that influence reaction rates. Hence it's possible to observe the true intrinsic reaction kinetics occurring for a set of reactions. In this work a novel microscale reactor for producing biohydrodeoxygenated diesel is developed and its performance investigated. Biohydrodeoxygenated diesel was produced by removal of oxygen from vegetable oils in presence of hydrogen at high temperatures and pressures on conventional NiMo/Al₂O₃ solid hydrotreating catalysts. Reactor was fabricated with photochemical etching to pattern post features on catalyst plates, laser ablation was used to make integrated oil slots and hydrogen hole mixer. Laser welding was used to seal reactor to provide a hematic seal. Six sigma methodologies were used to ensure fabrication method was in control, capable and stable. Sol gel method was used to deposit high surface area alumina on catalyst plate and wet impregnation method used to deposit active NiMo metal catalyst on support. Phosphorus was added to the preparation mixture as a structural promoter. Initial test of reactor with palm olein showed reactor was able to achieve complete conversion to mainly n-alkane liquid products at temperature 325°C, pressure 500psig under 3minutes of liquid residence time. Increase in palm olein concentration showed reaction was limited by stoichiometric hydrogen requirement. Model study of hydrotreating process was done with oleic acid. A 3³ factorial experimental design was done to optimize reaction conditions. Temperature was found to be most important followed by reactor pressure and liquid residence time. Effect of catalyst loading was done at 5wt%, 10wt% and 20wt% to study effect on conversion products. 10wt% loading was found to achieve maximum conversion and hydrodeoxygenation. A detailed mathematical model of reactor system was developed, encompassing flow, mass transport and reaction kinetics. From model developed, mass transport limitation free reaction rate constants was found from a simplex optimization algorithm using Comsol Matlab Live link. Model showed good agreement with experimental data and was used to predict maximum conversion and hydrodeoxygenation conditions.

▼ The diesel engine is known for its high efficiency, performance, and durability. With stringent fuel economy and emission regulations, diesel engines face increasing challenges. To accommodate emission regulations, fuel economy and performance requirements, modern diesel engines are equipped with the variable geometry turbocharger (VGT) and exhaust gas recirculation (EGR) system. VGT extracts energy from the exhaust gas to drive the compressor to improve transient response, steady-state performance, and fuel efficiency under a wide range of engine flow conditions. Meanwhile, EGR dilutes fresh air with exhaust gas to reduce the formation of mono-nitrogen oxides NO and NO2 (NOx). The VGT and EGR control design is complicated due to the natural coupling between VGT and EGR, and high nonlinearity of diesel engine air-path system. The extra assisted power and regenerative power on the turbocharger shaft further increase the control system complexity. In this dissertation, new approaches for turbocharger system modelling and multivariable control design for the coordinated actuation of the VGT-EGR system are investigated. The control design is further extended to hydraulic regenerative assisted turbocharger system.New modelling approaches for turbocharger system are proposed based on turbomachinery physics. Proposed turbine and compressor models eliminate the interpolation error, and especially, allow smooth extrapolation outside the mapped region. A high fidelity reduced order mean value model of a diesel engine for automotive application is developed based on developed turbocharger model. Further, new models for high-speed hydraulic turbines and centrifugal pumps are developed for hydraulic assisted and regenerative turbochargers.A regenerative hydraulic assisted turbocharger (RHAT) system is investigated in this dissertation. A system level approach based on 1-D simulations is used to understand the assist benefits and design trade-offs. Simulation results show that 3-5% fuel economy improvement for FTP 75 driving cycle, depending on different sub-component sizing. The study also identifies technical challenges for optimal design and control of RHAT systems.A linear controller design approach is proposed in this dissertation for regulating both boost pressure and EGR mass flow rate of the VGT-EGR system. The linear quadratic control with integral action is designed based on the linearized system. Local controllers are scheduled based on engine operational parameter: engine speed and fuel injection quantity. The gain scheduled liner controller is validated against baseline controller based on the nonlinear plant. Results show that designed multi-input and multi-output (MIMO) controller can well manage the trade-offs between boost pressure tracking and EGR mass flow tracking, compared to baseline controller (two single input single output (SISO) controllers). A novel approach is proposed for closed-loop control design with respect to engine performance and engine emission trade-offs. The controller design is further… Advisors/Committee Members: Zhu, Guoming, Khalil, Hassan, Schock, Harold, Mukherjee, Ranjan.

▼ Neste trabalho, o uso de bio-óleo foi proposto como alternativa aos combustíveis fósseis (petróleo). O bio-óleo foi produzido por pirólise de serragem de eucalipto e óleo de fritura de soja descartado, enquanto que o óxido de cálcio (CaO) foi usado como catalisador de pirólise para melhorar o rendimento de bio-óleo. A temperatura do sistema de pirólise foi iniciada a 25 °C e aumentada para 850 °C. A destilação atmosférica de bio-óleo bruto foi realizada após a pirólise e duas frações foram separadas à temperatura de 80−160 ºC (LFP, Fação Leve da Pirólise do bio- óleo) e 160−240 ºC (HFP, Fração Pesada da Pirólise do bio-óleo) e as quais foram analisadas por TGA (análise térmica gravimétrica), GC-MS (cromatografia gasosa acoplada a espectrometria de massa), FTIR (espectroscopia de infravermelho de transformação de Fourier) e RMN (espectroscopia de ressonância magnética nuclear) verificando-se que havia uma abundância de espécies contendo nitrogênio e oxigênio, bem como outras espécies reativas. Com o objetivo de reduzir a quantidade destas espécies após a pirólise, as frações LFP e HFP foram submetidas ao processo de craqueamento térmico na presença de hidrogênio (hidrogenação) e, novamente submetido a hidrogenação catalítica na presença do catalisador de NiMo. Após a hidrogenação catalítca, foi realizada a segunda destilação atmosférica obtendo-se duas frações à temperatura de 80−160 ºC (LFH, Fração Leve da Hidrogenação ) e 160−240 ºC (HFH, Fração Pesada da Hidrogenação) as quais foram igualmente caracterizadas pelas técnicas acima enumeradas, observando-se que mais de 60% de espécies nitrogenadas, oxigenadas e outras espécies reativas foram convertidas em hidrocarbonetos. As diferenças entre LFP, HFP e LFH, HFH foram apresentadas e discutidas criticamente neste trabalho, onde verificou-se após as análises fisico-químicas como composição química, entalpia de combustão, ponto de congelamento, densidade, viscosidade e volatilidadeque as frações obtidas pelo processo de Page 17 of 115 craqueamento e hidrogenação catalítica (LFH e HFH) podem ser usadas como combustíveis, porque apresentaram semelhanças muito próximas nas propriedades fisico-quimicas importantes do óleo de aviação (AF) e óleo diesel (DF). A partir destas informações foram preparadas formulações com 10 e 20% (m/m) das frações: HFH com óleo de aviação (AF) e LFH com oleo diesel (DF). As análises fisico quimicas destas formulações comparadas com o AF e DF mostraram o potencial uso destas frações como aditivos e consequente contribuição para a amenização da crise energética mundial.

Em termos de biocombustíveis líquidos, as questões relacionadas ao álcool estão em um patamar desenvolvido com a criação de uma cadeia produtiva em que todos os processos estão tecnologicamente resolvidos desde a produção da cana-de-açúcar até o consumo do álcool com o desenvolvimento dos carros multicombustíveis. Quanto à utilização dos óleos vegetais, algumas barreiras deverão ser vencidas, principalmente em comunidades isoladas, com ocorrência de oleaginosas, porém, com dificuldades na produção do biodiesel, devido aos custos ou à logística para o transporte dos produtos utilizados para o processo de transesterificação. Assim, a utilização do óleo vegetal in natura em motores diesel se torna importante fonte de energia e requer a utilização de técnicas e adaptações para o bom desempenho do motor, entre elas o aquecimento para redução da viscosidade e a alternância de combustível para promover a lavagem das tubulações de alimentação com óleo diesel. Objetivou-se com este trabalho avaliar a viabilidade do uso do óleo vegetal na forma in natura em motores diesel de baixa potência. Primeiramente foi realizado um estudo para verificar o efeito da temperatura na redução da viscosidade e desenvolver um sistema de aquecimento do combustível de baixo custo. Após o desenvolvimento do aquecedor, verificou- se por meio de ensaios dinamométricos, o desempenho do motor alimentado com misturas de óleo vegetal e óleo diesel em diferentes proporções e temperaturas de injeção. Por último, o motor foi avaliado em condições de trabalho, na geração de energia elétrica em um grupo gerador, operando por períodos de até 300 horas. Ao final, foram verificadas as medidas dos componentes do motor e os resíduos na câmara de combustão. As principais conclusões deste trabalho foram: os óleos brutos de Girassol. Milho e Soja alcançam à viscosidade do óleo diesel quando aquecidos as temperaturas acima de 160 C; o sistema de aquecimento foi eficiente para aquecer e manter a temperatura exigida; a temperatura de injeção e as proporções de óleo vegetal no combustível não influenciaram no regime de trabalho, na potência nominal e no torque; ocorreu aumento do consumo específico com o aumento da proporção de óleo vegetal no combustível; não ocorreu formação de resíduos nas proporções de até 50% de óleo vegetal que justificasse a descarbonização da câmara de combustão; e o custo de produção de energia elétrica aumentou em 4,66% com a utilização de Óleo Degomado de Soja na proporção de 50%, em relação ao óleo diesel.

In terms of liquid biofuels, the questions related to alcohol are in a developed level with the creation of a productive chain where all the processes are technologically decided since the production of the sugar cane until the alcohol consumption with the development of the multifuel cars. As for the use of vegetable oils, some barriers must be overcome, mainly in isolated communities, with occurrence of oil plant, however, with difficulties in the production of biodiesel, due to the costs or the logistic one for the transport of the…

Visando a redução de poluentes emitidos pelos motores de combustão interna com ignição por compressão, que operam conforme o ciclo diesel, foram desenvolvidos nos últimos anos dispositivos para a operação destes motores com novos combustíveis, que além da redução de poluentes barateariam o custo de operação, devido à oportunidade de utilização de alguns combustíveis com boa disponibilidade. No presente estudo analisa-se a operação do motor diesel utilizando gás natural como combustível. Neste caso utiliza-se o óleo diesel apenas como combustível piloto, que será responsável pela ignição do segundo combustível, o gás natural. Em diversas publicações constata-se o ganho ambiental e econômico desta aplicação, porém nada é comentado em relação à alteração de índices de confiabilidade e surgimento de novos modos de falha. Neste trabalho verifica-se através de ferramentas de análise de confiabilidade, tais como a análise do tipo FMEA e Árvore de falhas, quais os principais modos de falha que serão inseridos no motor de combustão interna do tipo diesel quando este passa a operar como bi-combustível, com gás natural. Para tanto, necessita-se subdividir o motor diesel em subsistemas mostrando sua estruturação em árvores funcionais e integrando o kit diesel gás neste sistema. A partir da análise de confiabilidade verifica-se a probabilidade de ocorrência de novos modos de falha, que necessitarão da elaboração de novos planos de manutenção ou mesmo alterações no projeto do subsistema de injeção de gás natural.

In order to reduce pollutants emissions from internal combustion engines with compression bend ignition, designed to operate as the Diesel cycle, it has been developed in recent years devices for the addition of new fuels, which in addition to reducing pollutants could lower the cost of operation, due to the possibility of use of some fuels with good availability. In this case it is used only the diesel oil as the pilot flame, which is responsible for the ignition of the second fuel, the natural gas. Many publications discuss the environmental and the economic gain with the use of natural gas as fuel application, however nothing is said about the change of reliability indexes and the appearance of new failure modes in the engine. In this study through system reliability analysis tools such as Faillure Mode Effects and Analisys and Fault tree analysis it is analysed, which are the main failure modes that are inserted into the internal combustion engine when it comes to operate as dual fuel. For that analyses it is necessary to split the engine into subsystems showing its functional trees and integrating diesel gas kit in this system. New failure modes appear with greater severity than the existing in the traditional diesel engine system, leading to new design and maintenance practices. The end user, according to his need, will have one more parameter to choose whether to adopt a Diesel Gas system.

A crescente busca por novos mercados, redução de custos e atendimento a legislação incentivam estudos e pesquisas no aperfeiçoamento dos materiais, processos e produtos. Uma vez que o bloco do motor é o componente mais importante, e que agrega maior peso e volume no motor, o bloco tem sido alvo de pesquisas na busca de motores mais eficientes. O desenvolvimento do material tradicionalmente utilizado para a fabricação de blocos de motores Diesel, o ferro fundido cinzento, alcançou seu limite. Neste contexto, o ferro fundido vermicular ou Compacted Graphite Iron (CGI) se apresenta como um substituto para tal aplicação com características de condutividade térmica e amortecimento próximas ao do ferro fundido cinzento, porém, com propriedades mecânicas superiores, possibilitando um redução do peso do motor e, consequentemente, economia de combustível, redução da emissão de poluentes (CO2, NOx e particulados) além do nível de ruído. Neste estudo foram determinadas, analisadas e comparadas as propriedades mecânicas e de fadiga do ferro fundido vermicular em relação ao principal material utilizado atualmente em blocos de motores Diesel: ferro fundido cinzento. Os experimentos foram realizados através de ensaios a partir de corpos de prova retirados de blocos de motores recolhidos aleatoriamente da produção, visando determinar às propriedades mecânicas e de fadiga baseado na metodologia da mecânica da fratura. As superfícies de fratura dos ensaios foram analisadas em microscópio eletrônico de varredura (MEV) a fim de caracterizar os micromecanismos de fratura. Resultados dos ensaios realizados evidenciaram as vantagens da utilização de ferro fundido vermicular quando comparado ao cinzento, pois apresentou resultados superiores em todos os ensaios mecânicos e taxa de crescimento de trinca de fadiga uma ordem grandeza menor. Através da análise fractográfica foi possível perceber a influência da morfologia da grafita no efeito concentrador de tensões.

The growing search for new markets, cost reduction, adding value to the product and making products according to the legislation for emissions control have consequently increased studies and research to find improvements in materials, process and products. Considered one of the most important and the heaviest component of the engine, the crankcase has been the main target of the search for more efficient engines. Currently the gray cast iron is the material traditionally used in the fabrication of Diesel engine crankcases, however it has reached its strength limit. In this context, the compacted graphite iron (CGI) comes as an alternative for such applications, with characteristics such as thermal conductivity and damping similar to the gray cast iron, but with superior mechanical properties, allowing the manufacturing of lighter crankcases, better performance and reduced environmental pollution by exhaust gases and fluids. This work was to determine, analyze and compare the mechanical and fatigue properties between gray iron and compacted graphite iron used in Diesel engine…

O MCI (Motor de Combustão Interna) é um produto largamente utilizado na indústria, o que o torna um objeto interessante de estudo, o qual requer constante desenvolvimento com implementação de novas tecnologias. Buscando contribuir para o avanço tecnológico na área, foi realizado um estudo do comportamento estrutural de uma de suas principais peças o bloco de cilindros. O mesmo é responsável pela união de todos os outros elementos, devendo ser suficientemente rígido para absorver os esforços oriundos da explosão no interior da câmara e resultantes das forças de oscilação de primeira e segunda ordem originárias das massas dos elementos oscilatórios do motor. Nesta dissertação desejando definir o carregamento principal sobre o bloco do motor, foram realizados diversos estudos, dentre eles: a regulagem da carga onde analisa-se analiticamente as transferências de gases que circulam em um motor, também foi realizada uma análise estequiométrica do combustível, determinando a sua composição e seu poder calorífico, na sequência foram determinados os parâmetros que caracterizam um motor, definidos aqui como cálculos de desempenho, estes foram inter-relacionados em uma planilha de Excel. Posteriormente o carregamento principal do bloco foi definido, realizando estudos de casos, com influência sobre a pressão de trabalho dos cilindros, dividindo-os em fatores de carga. A modelagem do bloco foi realizada no software Autodesk Inventor 2012, as dimensões e posicionamentos das partes foram definidas segundo a realização de cálculos e dimensões de projeto como: cálculos de tração nas roscas do cabeçote e dos mancais do motor; medidas de diâmetro e curso dos pistões; cálculos da velocidade média dos pistões, distâncias das engrenagens de distribuição e relações de cálculo como o raio da manivela sobre o comprimento da biela. Como resultado da modelagem obteve-se um sólido 3D o qual foi analisado no software Ansys Work Bench versão V12, definido o carregamento total sobre o bloco, ao final obteve-se uma análise gráfica dos deslocamentos totais, das tensões equivalentes, cortantes, normais e uma análise de fadiga do bloco do motor e sua capa do mancal, obtendo uma resposta estrutural direta para os cálculos analíticos de desempenho e os estudos de caso.

The ICM (Internal Combustion Engine) is a product widely used in the industry, which makes it an interesting object of study, which requires constant development with implementation of new technologies. Seeking to contribute to the technological advancement in the area, was accomplished a study of the structural behavior of one of its main parts the engine block. It is responsible for the union of all the other elements and must be sufficiently rigid to absorb the efforts originated of the blast within the cylinders and resultants of oscillation forces of first and second order originating from the masses of the oscillation elements from the engine. In this dissertation wishing define the main load on the engine block, were performed several studies,…

O emprego de óleos vegetais como combustível em motores ciclo diesel tem se demonstrado viável após diversos estudos de desempenho já desenvolvidos em diversos motores e configurações, porém apresentando algumas restrições quanto ao seu uso contínuo, dentre as quais se destacam a ocorrência de quebras do motor devido ao excesso de carbonização no cabeçote. No Brasil, a abundância de óleos de origem vegetal constitui um incentivo para a realização de estudos visando ao aproveitamento desses combustíveis alternativos, neste contexto, este trabalho apresenta um estudo das características macroestruturais da formação de sprays de óleo vegetal de soja in natura em um atomizador utilizado em motores diesel em condições de pressão semelhantes às de um motor. Para isso foi montada uma bancada que é constituída de uma câmara pressurizada projetada e fabricada para simular as mesmas condições de massa específica do ar obtidas dentro da câmara de combustão do motor ciclo diesel no instante do início da injeção do combustível. Também é dotada de um sistema de injeção de combustível projetado para que as pressões de funcionamento do conjunto porta injetor mecânico utilizado fosse atingido. O registro da formação do spray é realizado por meio de uma câmara de alta velocidade e alta taxa de aquisição de imagens, como o qual é possível avaliar o comportamento dos jatos de óleo de soja e óleo diesel quanto a distância de quebra, penetração da ponta, velocidade e ângulo de abertura de spray. Das propriedades físico-químicas do óleo vegetal de soja, a que mais se destaca com relação às propriedades do óleo diesel é a viscosidade, que para os líquidos utilizados nesse trabalho foi verificado que é aproximadamente 15 vezes maior que a viscosidade do óleo diesel. Essa grande diferença nas mesmas condições de temperatura produziram resultados de atomização bem distinta entre os líquidos e verifica-se a necessidade de modificação de mais parâmetros do que somente a densidade do gás para que a atomização seja mais próxima do óleo diesel e o óleo vegetal in natura possa ser utilizado nos motores, pois os regimes de atomização observados condizem com o previsto considerando as propriedades dos dois óleos nas condições testadas.

The use of vegetable oils as fuel in diesel engines has proven to be viable after several performance studies already developed in several engines and settings, but presenting some restrictions on its continued use, among which stand out the occurrence of engine failures due to over-charred on the head. In Brazil, plenty of vegetable oils is an incentive to carry out studies for the use of these alternative fuels, in this context, this work presents a study of macro-structural characteristics of the formation of vegetable oil sprays soy in kind in an atomizer used in diesel engines into pressure conditions similar to those of an engine. To this it was mounted on a stand which consists of a pressure chamber designed and manufactured to simulate the same conditions of air density obtained within the combustion chamber…

▼ Abstract: The main goal of this study is to evaluate if the determination of metal concentration in lubricant oil by ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy) is capable to help on eventual wear failures diagnosis on Diesel engines that are not detected in the production test cycle (running in). The data processing was done using statistical methods. Parameters like load, engine speed, pressures, temperatures, as well wear severity, cannot be enough to show the failure during the engine test time postponing the failure occurrence to OEM or field. The metallic elements concentration knowledge in lubricant oil is useful to evaluate specific engines parts wear allowing a preventive action in order to avoid catastrophic failures. Starting from the historic data analysis available in the company it was defined the concept of wear signature looking for oil analysis results behavior understanding, where it was noticed significant values variability due to random and systemic errors. The ICP-OES validation for premature wearing detection on engines was done starting from most usual failure mode found on internal combustion engines that is connecting rod scuffing. The tribological system bearing, crankshaft pin and oil was set to simulate a failure by an external contamination coming from the connecting rod cracked assembly area. As expected, the engines were approved according to current controls. After engine disassembly it was noticed that the tribological system was heavy damaged due to bearing wear whose surface layer composition is made of aluminum and tin. In the univariate oil analysis of metals dissolved it was detected tin which is not expected to be finding in this engine model. In the multivariate data processing it was possible to analyze the dissolved metals correlation whose statistical analysis make possible to distinguish conforming engines from non-conforming engines in a quantitative and objective way. So it is possible to conclude that the ICP-OES method to analyze dissolved metal in oil is effective showing sensibility to detect wear between crankshaft pin and connecting rod bearing system Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Button, Sérgio Tonini, 1958- (advisor), Universidade Estadual de Campinas.

▼ Abstract: Automotive companies involved in diesel engines development often use durability tests to confirm the achievement of the specifications established in a project, aiming to build the desired level of quality in a product being marketed. In this work a software based tool is used to estimate the reliability growth evolution trough engine development phase. The essential concepts for the estimation of the value of reliability and of its growth, the typical process of product development and its life cycle in the market are considered. A procedure currently performed by an automotive company with significant market share in Brazil and abroad and the validation tests it uses is described. A new procedure is proposed aiming to improve the current model through development time reduction and early failures identification and correction. It consists in classifying the failures found during testing, identifying the systems more susceptible to failure in the conditions specified during operation, and applying a software tool based on the Crow-AMSAA model to estimate the reliability growth, based on the MTBF and the shape parameter â. The reliability growth curve is generated using the desired goal at the end of development, predicting the evolution of reliability throughout the development phase. The proposed model enables evaluation of the effectiveness of corrective actions; it is a tool that can be used to judge if the reliability goal has been reached and if the resources allocated to development are enough. The data obtained during the process allow the formation of a standardized database to be used in future developments Advisors/Committee Members: UNIVERSIDADE ESTADUAL DE CAMPINAS (CRUESP), Azevedo, Irany de Andrade (advisor), Universidade Estadual de Campinas.

Brazil is considered a country of an incommensurable biodiversity, justifying in this way, its enormous variety in oleaginous. It is considered that, in a close future, the petroleum reservations economically viable will tend to the shortage. Beside it, the exacerbated current price levels of the petroleum barrel in the international market, the possibility of employment generation and income with the consequent fixation of the man in the country, the excellent and varied climatic conditions and several types of terrain do that the country, with extensive workable areas, stand out in the world scenery if considering its great potentiality on generation of alternative fuels. The environmental preservation, important subject nowadays, does, also, that the human being work in searches for the development of alternative energies, mainly those originating from renewable and biodegradable sources of sustentable character. Being taken in consideration those searches, the purpose of this work was to evaluate the performance of a diesel engine working in different moments with mineral diesel and mixtures of mineral diesel and biodiesel in the equivalent proportions B2 (98% mineral diesel and 2%biodiesel), B5 (95% mineral diesel and 5%biodiesel), B20 (80% mineral diesel and 20%biodiesel), and, finally, B100 (100% biodiesel). The experiment was accomplished in the dependences of the Engineering Department at UFLA - Federal University of Lavras, in Lavras, Minas Gerais, in July, 2005.

O Brasil Ã considerado um paÃs de uma biodiversidade incomensurÃvel, justificando-se, assim, sua enorme variedade em oleaginosas. Estima-se que, em um futuro prÃximo, as reservas de petrÃleo economicamente explorÃveis tendam Ã escassez. AlÃm disso, os atuais nÃveis exacerbados dos preÃos do barril de petrÃleo no mercado internacional, a possibilidade de geraÃÃo de emprego e renda, com a conseqÃente fixaÃÃo do homem ao campo, as excelentes e variadas condiÃÃes climÃticas e os diferentes tipos de relevo fazem com que o paÃs, com extensas Ãreas agricultÃveis, se destaque no cenÃrio mundial em relaÃÃo Ã sua grande potencialidade de geraÃÃo de combustÃveis alternativos. A preservaÃÃo ambiental, importantÃssima questÃo da atualidade, vem, tambÃm, fazendo com que o ser humano trabalhe na busca do desenvolvimento de alternativas energÃticas, principalmente aquelas oriundas de fontes renovÃveis e biodegradÃveis de carÃter eminentemente sustentÃvel. Levando-se em consideraÃÃo essa busca, o objetivo deste trabalho foi avaliar o desempenho de um motor ciclo diesel, funcionando em momentos distintos com diesel mineral e misturas de diesel mineral e biodiesel nas proporÃÃes equivalentes a B2 (98% diesel mineral e 2% biodiesel), B5(95% diesel mineral e 5% biodiesel), B20(80% diesel mineral e 20% biodiesel) e, finalmente, B100 (100% biodiesel). O experimento foi realizado nas dependÃncias do Departamento de Engenharia da Universidade Federal de Lavras (UFLA), em Lavras, Minas Gerais, em julho de 2005.

Neste documento descreve-se o projecto desenvolvido na unidade curricular de Tese e Dissertação durante o 2º ano do Mestrado de Engenharia Electrotécnica e de Computadores no ramo de Automação e Sistemas, no Departamento de Engenharia Electrotécnica (DEE) do Instituto Superior de Engenharia do Porto (ISEP). Com a revolução dos sistemas automóveis, toda a gestão do funcionamento do motor passou a estar a cargo de um sistema electrónico, originando a gestão electrónica do motor. O seu objectivo é fazer com que o nível de emissões de gases poluentes esteja dentro dos padrões exigidos, sem comprometer o desempenho e conforto da condução. O projecto escolhido teve como base o uso da tecnologia das redes neuronais artificiais (RNA) para controlo de emissões. Relativamente à implementação, foram consideradas diferentes estruturas de controlo. A análise exposta neste trabalho trata de perceber em que medida é que a introdução das redes neuronais melhora o controlo de um processo. Os testes de desempenho são aplicados no controlo de um motor diesel com VGT e EGR, sendo realizadas através do software MATLAB. As simulações efectuadas têm diferentes configurações de modo a tirar conclusões o mais gerais possível.

This dissertation reports the project developed in the thesis/dissertation course during the 2nd year of the Master of Electrical and Computer Engineering in the field of Automation and Systems, Department of Electrical Engineering (DEE) of the Instituto Superior de Engenharia do Porto (ISEP). With the evolution of automotive systems, an electronic system became responsible for all the engine operations, yielding the electronic engine management system. Its goal is to comply with the required standards for the level of greenhouse gas emissions, without compromising the car performance and driving comfort. The chosen project was based on the use of the technology of artificial neural networks for the control of emissions. In what concerns the implementation, it was considered different control structures. The proposed idea in this work is the introduction of artificial neural networks (ANN) to improve the process control. The performance tests are conducted through the use of MATLAB software and in the control of a diesel engine with VGT and EGR. The simulations have different settings in order to get the most general conclusions.

[pt] Este trabalho avaliou o comportamento de um motor do ciclo Diesel, operando no modo original (Diesel puro) e no modo bicombustível (Diesel / etanol), em dois modos de hidratação do álcool (70 e 93 graus INPM). A rotação foi mantida fixa em 1800 rpm. A finalidade foi estudar os parâmetros de desempenho do motor e analisar a liberação de calor pela combustão, como também, o calor trocado com as paredes. Avaliou-se como parâmetros de desempenho, o rendimento térmico, consumo específico de combustível e emissão de poluentes. A fase inicial do trabalho constou de ensaios experimentais realizados no conjunto motor / dinamômetro nos modos mencionados acima. O objetivo foi coletar a variação de pressão no interior do cilindro, consumo de combustível, emissão de gases, temperaturas em pontos estratégicos, entre outros. Em uma segunda etapa foi realizada uma análise dos parâmetros de desempenho e da liberação de calor. Para emissões de poluentes, observou-se uma diminuição de MP em altas taxas de substituição. No entanto, notou-se um aumento elevado de HC. Em baixas cargas e taxas de substituição elevadas houve redução de emissão de NOx. O rendimento térmico apresentou comportamentos similares em 70 e 93 graus INPM. Em altas cargas e altas taxas de substituição houve um sensível aumento do rendimento quando comparado ao modo original. O rendimento foi menor para baixas cargas com altas taxas de substituição, em relação ao modo original. O início da combustão no modo bicombustível foi antecipado em relação ao modo original, nas condições de altas cargas e máximas taxas de substituição. Isto foi devido à liberação de calor que ocorreu mais cedo no modo bicombustível. Ressalta-se que, nas mesmas condições, houve a ocorrência de um maior calor trocado com as paredes do cilindro, em ambos os modos de hidratação (70 – 93 graus INPM), quando comparado ao modo original.

[en] This work aimed to evaluate a Diesel cycle engine operating in the original (only Diesel) and dual-fuel modes (Diesel / ethanol) in two levels of hydration of alcohol (70 and 93 degrees INPM). Speed was kept fixed at 1800 rpm. The purpose was to study the parameters of engine performance and analyze the heat release by combustion and heat exchanged to the cylinder’s walls. For parameters of performance, evaluation of thermal efficiency, specific fuel consumption and emissions were conducted. Initial activities consisted in trial tests on the engine / dynamometer in the two modes as mentioned above. The goal was to collect the variation of indicated cylinder pressure data, as well as fuel consumption, emissions and temperatures at strategic points. Secondly, performance parameters and heat release analysis was performed. For emissions, a decrease in PM was found at higher replacement rates; however, in the same condition a large increase in HC was obtained. At low loads and at higher replacement rates, NOx emissions were reduced. Thermal efficiency showed similar behavior at 70 and 93 degrees INPM. At high loads and at higher replacement rates a significant…

▼ This thesis describes an investigation into the spatial species conversion profiles of a Cu-zeolite SCR under engine conditions at low exhaust gas temperatures; this was then compared with a CFD model that models the catalyst via a porous medium measuring 5 x 5 x 91 cells assuming a uniform cross-sectional flow distribution. Species conversion rates were sampled at fixed points in the axial direction. The analysis of the spatial conversion profiles is a more rigorous method in assessing the ability of a mathematical model to predict the experimental data. It can also assist in the optimisation of the catalyst size, minimising packaging requirements and manufacturing costs. The experiments were undertaken on a light-duty diesel engine at a speed of 1500rpm, and at a load of 6bar BMEP; this provided exhaust gas temeraqtures between 200 and 220°C. NO2:NOx ratios were controlled by changing the size and position of the diesel oxidation catalyst, the inlet NH3: NOx ratio was also also varied, ammonia gas was used instead of urea for the purposes of simlicity. The advantage of testing on an actual engine over lab-babed studies is that the conditions such as exhaust gas composition are more realistic. A 1D CFD model was constructed using the ‘porous medium approach’ with kinetics obtained from open literature. Results from the simulations were then compared with the experimental data for the same engine conditions. It was observed that the majority of the NOx conversion took place in the first half of the brick for all NH3: NOx ratios investigated, and that the formation of N2O via NO2 and ammonia had the same influence as the ‘fast’ SCR reaction just after the inlet, which the CFD model failed to predict for the base case analyses. The influence of the inlet ammonia on the model was also noticed to be greater than in the experiments. Simple transient analyses were also undertaken on the short SCR bricks for NO2: NOx ratios of 0.6 and 0.07, and it was observed that the response time to steady-state was noticeably higher in the experiments than in the model. Modifications made to the model, including decreasing the influence of the ‘fast’ SCR reaction, and the addition of an empirical term onto the ammonia adsorption provided a noticeably better agreement for different NH3: NOx injection ratios. The desorption kinetics in the model were also altered by increasing the strength of the bonding of the ammonia onto the adsorption sites. This improved the transient agreement between the model and the experiments, but reduced the steady-state concentrations at the exit of the brick for all NH3:NOx ratios investigated.

A indústria, ao longo dos anos, vem trabalhando no sentido de melhorar a eficiência dos motores. Mais recentemente surgiu, também, a necessidade de reduzir as emissões de poluentes para se adequar às severas leis ambientais. Isto tem despertado o interesse de desenvolver pesquisas no sentido de substituir os combustíveis derivados do petróleo por diversos tipos de combustíveis menos poluentes, tais como: misturas de óleo diesel com ésteres de óleos vegetais e óleo diesel com óleos vegetais e álcool, emulsões e microemulsões. Este trabalho tem como objetivo desenvolver sistemas microemulsionados a partir de tensoativos não iônicos dos grupos nonilfenois etoxilados e álcoois láuricos etoxilados, misturas com etanol/diesel e misturas diesel/biodiesel para uso em motores diesel. Em uma primeira fase, visando selecionar os sistemas microemulsionados, foram obtidos diagramas ternários das misturas, sendo os sistemas compostos por: tensoativos não-iônicos, água como fase polar e como fase apolar o diesel e/ou misturas diesel/biodiesel. Os sistemas microemulsionados e as misturas, que representam os combustíveis estudados, foram caracterizados quanto à massa específica, a viscosidade, o índice de cetano e o ponto de fulgor. Também foram avaliados o efeito da temperatura nos sistemas microemulsionados, o desempenho do motor, e as emissões de monóxido de carbono, óxidos de nitrogênio, hidrocarbonetos não queimados e fumaça de todos os sistemas. Os ensaios de consumo específico e das emissões em função da potência foram realizados em um motor de ciclo diesel em uma bancada dinamométrica e o analisador de emissões GreenLine 8000. Os resultados mostraram um pequeno aumento no consumo específico para os combustíveis microemulsionados, nas misturas diesel/biodiesel em relação ao diesel puro, porém com uma redução nas emissões de óxidos de nitrogênio, hidrocarbonetos não queimados, índice de fumaça e óxidos de enxofre

The industry, over the years, has been working to improve the efficiency of diesel engines. More recently, it was observed the need to reduce pollutant emissions to conform to the stringent environmental regulations. This has attached a great interest to develop researches in order to replace the petroleum-based fuels by several types of less polluting fuels, such as blends of diesel oil with vegetable oil esters and diesel fuel with vegetable oils and alcohol, emulsions, and also microemulsions. The main objective of this work was the development of microemulsion systems using nonionic surfactants that belong to the Nonylphenols ethoxylated group and Lauric ethoxylated alcohol group, ethanol/diesel blends, and diesel/biodiesel blends for use in diesel engines. First, in order to select the microemulsion systems, ternary phase diagrams of the used blends were obtained. The systems were composed by: nonionic surfactants, water as polar phase, and diesel fuel or diesel/biodiesel blends as apolar phase. The microemulsion systems and blends, which represent the studied fuels, were characterized by density, viscosity,…
