▼ A 0.8L, 3 cylinder turbocharged diesel engine was retrofitted for premixed and port injected dual fuel operation. Diesel baseline testing was conducted and conventional diesel trends in efficiency and emissions were found in relation to pilot start of injection (SOI) and load. However, at low loads the combustion mode deviated from a conventional diffusion flame. The end of injection was found to occur well before start of combustion (SOC), suggesting that combustion was closer to premixed charge compression ignition (PCCI). Dual fuel mode operation was carried out using two methods. First, the fuel proportions were varied while maintaining 25% full load (FL). The brake fuel conversion efficiency (BCFE), unburned hydrocarbons (UHC) and CO emissions suffered, while NOx emissions and peak pressure decreased with increased methane substitution. Ignition delay increased with methane substitution. Port injected dual fuel modes yielded improved BFCE, but similar UHC and CO emissions compared to premixed dual fuel. Second, constant pilot tests with small pilot quantities resulted in decreased BFCE and increased CO and UHC emissions compared to diesel-only. Increasing load resulted in improved BFCE relative to diesel performance and decreased UHC and CO emissions. Constant pilot NOx emissions were lower than diesel-only at low load, but far exceeded diesel levels above 50%FL. Increased pilot injection quantity provided emissions and BFCE benefits compared to the minimum pilot quantity for low loads only (below 50%). Advancing SOI increased peak cylinder pressure and temperature, and improved UHC and CO emissions. Further advancement resulted in decreased BFCE due to very early heat release (BTDC). Similarly at 50%FL SOI advance increased peak pressure and temperature. Much less improvement in BFCE was found with SOI advancement, but UHC and CO emissions were reduced. At very early SOI angles SOC and peak pressure was retarded and yielded a slow ignition event followed by a single heat release event. Increasing the load and/or pilot quantity resulted in further advancement of SOI timing compared to the smaller pilot quantity. All tests reported in this thesis were conducted at an 1800RPM nominal engine speed.

▼ Biodiesel and ethanol are most widely considered as a promising alternative fuel to petroleum diesel and gasoline due to their renewable nature and potential reduction in greenhouse gas emissions. This thesis applies three different combustion strategies that can achieve the increased use of these biofuels without compromising engine efficiency and pollutant emissions, which includes 1) coconut oil-based biodiesel combustion with varying blending ratios of biodiesel and petroleum diesel, 2) dual-fuel combustion of port injected ethanol and direct injected biodiesel blend, and 3) neat ethanol combustion in a common-rail diesel engine. All of the three combustion strategies are realised in the same single-cylinder light-duty diesel engine. For the coconut-oil biodiesel combustion, a higher biodiesel blending ratio results in decreased indicated power but the improved lubricity of coconut-oil biodiesel and hence reduced friction loses leads to similar brake power of diesel. From the engine-out emissions, a significant reduction of smoke emissions are observed with an increase in the biodiesel blending ratio, which is explained by the oxygenated molecular structures and reduced aromatics contents of biodiesel. Also, the slower reaction and leaner mixture of high biodiesel blends, together with shorter carbon chain length of coconut-oil biodiesel, cause the reduced flame temperature and thereby decreasing NOx emissions. Nevertheless, a significant increase in the brake specific fuel consumption limits the highest biodiesel blending ratio at B40. The increased use of biofuel is achieved via an alternative approach using dual-fuelling of ethanol and B40. The results show that the indicated power increases with increasing ethanol energy fraction because the increased premixed charge leads to faster burning and thereby increasing the heat release rate. This effect, together with the reduced friction loss of coconut-oil biodiesel, results in higher brake power than diesel combustion while both smoke and NOx emissions are significantly reduced. The most promising results are found when neat ethanol is injected directly into the cylinder using a common-rail system, which achieve 100% biofuel usage. The optimised injection strategy using a split injection comprised of early bottom-dead-centre injection and near top-dead-centre injection achieves 50% higher fuel conversion efficiency despite 5% lower brake specific fuel consumption. The NOx emissions are reduced 30% while smoke emission is negligible.

▼ This thesis is about modelling of the combustion and emissions of dual fuel HCCI engines for design of “engine combustion system”. For modelling the combustion first the laminar flamelet model and a hybrid Lagrangian / Eulerian method are developed and implemented to provide a framework for incorporating detailed chemical kinetics. This model can be applied to an engine for the validation of the chemical kinetic mechanism. The chemical kinetics, reaction rates and their equations lead to a certain formula for which the coefficients can be obtained from different sources, such as NASA polynomials [1]. This is followed by study of the simulation results and significant findings. Finally, for investigation of the knock phenomenon some characteristics such as compression ratio, fuel equivalence ratio, spark timing and their effects on the performance of an engine are examined and discussed. The OH radical concentration (which is the main factor for production of knock) is evaluated with regard to adjustment of the above mentioned characteristic parameters. In the second part of this work the specification of the sample engine is given and the results obtained from simulation are compared with experimental results for this sample engine, in order to validate the method applied in AVL Fire software. This method is used to investigate and optimize the effects of parameters such as inlet temperature, fuels ratio, diesel fuel injection timing, engine RPM and EGR on combustion in a dual fuel HCCI engine. For modelling the dual fuel HCCI engine AVL FIRE software is applied to simulate the combustion and study the optimization of a combustion chamber design. The findings for the dual fuel HCCI engine show that the mixture of methane and diesel fuel has a great influence on an engine's power and emissions. Inlet air temperature has also a significant role in the start of combustion so that inlet temperature is a factor in auto-ignition. With an increase of methane fuel, the burning process will be more rapid and oxidation becomes more complete. As a result, the amounts of CO and HC emissions decrease remarkably. With an increase of premixed ratio beyond a certain amount, NOX emissions decrease. With pressure increases markedly and at high RPM, knock phenomenon is observed in HCCI combustion.

▼ This thesis presents a systematic investigation of advanced dual-fuel low temperature combustion (LTC) strategy, reactivity-controlled compression ignition (RCCI), on a modified diesel engine to obtain high thermal efficiency and low engine-out emissions using hydrous ethanol as the primary fuel. Direct use of hydrous ethanol in internal combustion engines has been shown to provide significant energy savings in the bio-ethanol production process, substantially improving life-cycle energy use and economics compared to commercially available anhydrous ethanol. While many studies have reported high thermal efficiency and extremely low soot and NOX emissions without exhaust aftertreatment systems in RCCI engines fueled with petroleum-based fuels, limited work has been done regarding the characteristics of performance and emissions of RCCI operation using hydrous ethanol. In this work, a systematic experimental investigation has been conducted to explore the operability region, characterize the performance and emissions, and optimize the key operating parameters of RCCI operation using hydrous ethanol as the primary fuel. It has been shown that hydrous ethanol with water content of up to 25% by volume can be effectively used in RCCI operation with ethanol energy fraction up to 75% over a wide engine load range. However, intake charge heating is needed at low loads and exhaust gas recirculation (EGR) is required under high load conditions. Response surface methodology (RSM) has been shown to be an efficient approach of identifying and optimizing the key engine operating parameters of RCCI operation with reduced experimentation. The performance and emissions characteristics of RCCI combustion have been shown to be different and subject to the influence of different engine operating parameters under different engine operating conditions. NOX and soot emissions have been considerably reduced with the optimal settings of operating parameters generated from the RSM models. The fumigated low reactivity fuel has been shown to primarily contribute to the relatively high hydrocarbon emissions from the RCCI combustion. The particulate matter (PM) emissions from RCCI combustion have been shown to be primarily composed of semi-volatile organic compounds and a smaller fraction of solid carbonaceous particles. The characteristics of RCCI PM emissions vary when using different low reactivity fuels and they are highly sensitive to dilution conditions such as dilution ratio and sampling system temperature.

▼ A transported probability density function (PDF) method is coupled with a deforming/moving grid with periodic removal/addition of layers of cells to accommodate piston motion in engine modeling. The coupled model is used to simulate in-cylinder combustion processes for heavy-duty compression-ignition engines. First, the influences of unresolved turbulent fluctuations in composition and temperature (turbulence-chemistry interactions – TCI) on heat release, flame structure, and emissions are explored at four operating conditions in a conventional diesel engine. TCI are isolated and quantified by comparing results from the transported PDF model with those from a model that neglects the influence of fluctuations on local mean reaction rates (a well-stirred-reactor – WSR-model), with all other aspects of the modeling being the same (e.g., spray model, gas-phase chemical mechanism, and soot model). Computed pressure and heat-release traces, turbulent flame structure, and emissions from the WSR and PDF models show marked differences, with the PDF-model results being in closer agreement with experiment in most cases. While the peak cylinder pressure values predicted by the PDF model are within 3% of the measured data, those predicted by the WSR model differ up to 10.5% from experimental data. The soot results are especially striking. Computed soot levels from the PDF model are within a factor of five of the measured engine-out particulate matter, and computed soot levels from the WSR and PDF models differ by up to several orders of magnitude, with the PDF-model results being in much closer agreement with experiment. These results highlight the importance of TCI in compression-ignition engines. Second, one of the advanced combustion modes – partially premixed combustion – is studied using gasoline as fuel. It is observed that at least four components are required to form a gasoline surrogate to predict the ignition characteristics, flame structure and emissions accurately. A good surrogate chemical mechanism needs to be validated for two-component primary reference fuel (PRF) mixtures (mixtures of n-heptane and iso-octane) and three-component toluene reference fuel mixtures (mixtures of n-heptane, iso-octane and toluene) under heavy-duty engine conditions before using it to predict gasoline combustion characteristics. Several PRF chemical mechanisms are tested to model the combustion of two-component PRF mixtures, and none of them satisfactorily match the experimental data. Those mechanisms that have been primarily developed to study leaner combustion conditions predict a longer ignition delay compared to experiments. Finally, a new combustion concept based on advanced combustion strategies has been explored. A preliminary study of this concept shows tremendous potential to increase efficiency.

▼ There is a strong demand for a versatile computational model in the design of modern engines such as homogeneous charge compression ignition (HCCI) and partially premixed compression ignition (PPCI) engines. A robust model is required to describe accurately both the chemistry and turbulent mixing processes in the reacting flow. Although the existing computational fluid dynamics (CFD) codes coupled with detailed kinetics models may reproduce some realistic results, the excessive computational cost prevents them to be applicable as engineering tools. The present study aims at developing a new modeling approach that can describe the combustion process with high fidelity and computational efficiency. In this study, a two-conserved scalar approach is proposed to model HCCI and PPCI combustion. The first conserved scalar, the mixture fraction Z, is introduced to capture the inhomogeneities in the fuel-air mixture, and the second conserved scalar, the initial EGR fraction J, is introduced to capture the inhomogeneities in the fresh mixture-EGR charge. The main benefits of this approach are the reduction of dimensionality and the compactness of the domain in the conserved scalar plane, and the capability to use different resolutions for the chemistry and the fluid mechanics calculation. To solve the flow in the conserved scalar plane, two algorithms are proposed. First, the flamelet (zone) creation strategy is introduced to discretize the conserved scalar space based on its mass distribution and reactivity. The second part is the regeneration procedure which accounts for the nonlinear effect of EGR on reaction rates. Test results from the two-conserved scalar approach are compared to those obtained by direct calculation, and it is demonstrated that the regeneration process in the present approach can properly account for the nonlinear effects arising from chemical reactions, as an improvement over the representative interactive flamelet (RIF) approach. The two conserved scalar model is subsequently implemented into the KIVA-3v code to simulate HCCI combustion. The results show excellent agreement with experimental data, demonstrating that the present approach achieves the initial modeling objectives. Finally, the two conserved scalar approach is applied to the modeling of direct injection (DI) combustion with an assumption of non-homogeneous EGR. Discrepancies relative to the results from direct calculations are identified. These are attributed to the limitation inherent to the flamelet model, and further improvements are suggested as future work. Advisors/Committee Members: Assanis, Dionissios N. (advisor).

The ever increasing demand and depletion of fossil fuels along newlinewith environmental concern has prompted search for alternate fuels. One such newlinepotential substitute to fossil fuels is biodiesel that ensures sustainable energy newlinesource. Biodiesel is poised to make important contributions to world energy newlinesince it is renewable, bio degradable and non-toxic in nature. Various oils newlinehave been used in biodiesel production owing to their availability among newlinewhich fish oil is a significant one. In the present work, experimental investigations were carried out newlineon a single cylinder four stroke, air cooled, constant speed, direct injection newlinediesel engine with a rated output of 4.4 kW at 1500 rpm at different loads and newlineat different injection timings, 21o, 24o and 27obTDC for studying the newlineperformance, emission and combustion characteristics of diesel engine fuelled newlinewith Ethyl Ester of Fish Oil (EEFO) and its blends. newlineOxides of Nitrogen (NOx), Unburnt Hydrocarbon (UBHC) and newlineCarbon Monoxide (CO) emissions in biodiesel blends were lower than diesel, newlinewhereas smoke was found to be higher.

▼ Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. Engine emissions such as carbon dioxide that has an effect on a global scale and other harmful emissions that affect on a local scale such as soot and nitrogen oxides are on the rise, forcing the countries to take measures on controlling and reducing them.Gasoline Partially Premixed Combustion (PPC) is an alternative combustion concept that can offer both high indicated efficiency and low exhaust emissions in terms of NOx and soot, compared to conventional diesel combustion (CDC). Previous research has shown that this concept can work well with gasoline fuels of different octane ratings and can be used both in light and heavy duty engines. Although PPC has been tested substantially in research engines, results from engine designs that are closer to production are limited.In this thesis, PPC is evaluated in a multi-cylinder light duty diesel engine. Results show that while it can perform well with both low octane RON75 and higher octane RON90 gasoline, the available load range is limited compared to similar diesel operation. Despite that, efficiency is high, with gross indicated numbers of around 48 %, while brake efficiency reaches up to 41 %. Soot emissions are improved compared to diesel while NOx emissions are in similar numbers. A reason for that is the limited use of EGR compared to previous studies. This was deemed necessary to improve the upper achievable load of the engine.As the use of EGR was a limiting factor, an evaluation of the two possible EGR routes was performed, to investigate the possible gains compared to single route operation. Results show that by combining routes possibility for a 4 % gain in efficiency could be found. Also, low load operation is limited due to the type of combustion and the fuel that is used. A minimum amount of temperature is necessary to promote combustion at lower loads and that is not always possible. By utilizing the glowplugs of a diesel engine, combustion stability can be improved, helping reducing the low load limit.Finally these engine results are evaluated on a simulation model of a hybrid PPC powertrain. Even with an unoptimized diesel engine under PPC conditions, fuel consumption and emissions are comparable to a similar diesel powertrain from a production vehicle, showing that with further development, PPC can become a future possibility that can replace the less efficient SI engine.

Os motores de combustão interna são equipamentos aplicados em diversas áreas, tendo destaque no setor de transporte e na geração de energia elétrica. Desta forma, é necessário que seu uso seja racionalizado e que seu desempenho seja continuamente melhorado, tanto nos aspectos técnicos como ambientais. Neste contexto, esta tese visa contribuir com a literatura na área, avaliando os efeitos do uso do etanol e do etanol com maiores frações de água (até 30% em volume), no comportamento de pequenos motores de ignição por compressão. Neste estudo, para aplicação do etanol, foi empregada a técnica da fumigação, que consiste na injeção do mesmo no coletor de admissão de ar, havendo, desta forma, a pré-mistura com o ar e substituição parcial do óleo diesel que é injetado dentro da câmara de combustão. Dois diferentes motores monocilíndricos foram ensaiados: Agrale M93ID, acoplado a um gerador, e Ricardo Proteus, acoplado a um dinamômetro. Os principais parâmetros utilizados para avaliação foram as eficiências, os consumos de combustíveis, emissões e características do processo de combustão. Os resultados mostraram que há viabilidade técnica do uso do etanol com elevada fração de água pelo método da fumigação, por vezes com eficiências menores do que aquelas apresentadas nos ensaios em condição testemunha. No caso do motor Agrale, para a carga de 5,6 kW (no alternador) a máxima eficiência obtida foi próxima a 24,4% enquanto que para a carga de 7,2 kW foi 24,9%, ambas em condições de substituições intermediárias. Neste mesmo motor, quando usada carga de 7,2 kW, a pressão dentro do cilindro reduziu progressivamente com o aumento da substituição por etanol, chegando a cair 27,6% na condição de maior substituição. Como resultado do aumento da substituição, também foi constatado maior atraso na ignição. No caso do motor Ricardo Proteus, a máxima eficiência indicada obtida foi 44,2% para a condição de menor substituição, quando usado etanol com 15% de água adicional, e o aumento progressivo da substituição proporcionou redução das eficiências. O comportamento da curva de pressão dentro do cilindro mostrou-se afetado pelo ponto de injeção direta, sendo que em elevada substituição, na condição em que o etanol possuía 30% de água adicional e ponto de injeção direta em 326°, chegou ao pico 93,1 bar, enquanto para condição de substituição semelhantes no ponto de injeção direta de 346°, chegou a 76,3 bar.

The internal combustion engines are application equipment in several areas, having ample prominence in the transportation sector and electric power generation. In this way, it is necessary that its use is rationalized and that its performance is continuously improved, both in technical and environmental aspects. In this context, this thesis aims to contribute with the literature in the area, evaluating the effects of the use of ethanol and ethanol with higher water fractions (up to 30% by volume), in the behavior of small compression ignition engines. In this study for ethanol application the fumigation technique was employed, which…

▼ The conversion of existing diesel engines to natural-gas spark ignition operation by adding a gas injector in the intake manifold for fuel delivery and replacing the diesel fuel injector with a spark plug to initiate and control the combustion process can reduce U.S. dependence on petroleum imports and curtail engine-out emissions. As the conventional diesel combustion chamber (i.e., flat head and bowl-in-piston) creates high turbulence, the engine can operate leaner, which would increase its efficiency and reduce emissions. However, natural gas combustion in such retrofitted engines presents differences compared to that in conventional spark ignited engines. Subsequently, the main goal of this study was to investigate the characteristics of natural gas combustion inside a diesel-like, fast-burn combustion chamber using a unique array of experimental and numerical tools. The experimental platform consisted of a heavy-duty single-cylinder diesel engine converted to natural-gas spark ignition and operated at a low-speed, lean equivalence ratio, and medium-load condition. The engine can also operate in an optical configuration (i.e., the stock piston and cylinder block can be replaced with a see-through piston and an extended cylinder block), which was used to visualize flame behavior. The optical data indicated a thick and fast-propagated flame in the piston bowl but slower flame propagation inside the squish region. In addition, a 3D numerical model of the optical engine was built to better explain the geometry effects. The simulation results suggested that while the region around the spark plug location experienced a moderate turbulence that helped with the ignition process, the interaction of squish, piston motion, and intake swirl created a highly-turbulent environment that favored the fast burn inside the bowl and stabilized the combustion process. However, the squish region experienced a much lower turbulence, which, combined with the reduced temperature and pressure during the expansion stroke and its higher surface-to-volume ratio, reduced the burning velocity and the flame propagation, but also avoided knocking. Consequently, the bowl-in-piston geometry separated the lean-burn natural gas combustion into two distinct events. To extend the optical findings, the metal engine configuration was used to investigate the effects of gas composition, spark timing, equivalence ratio, and engine speed on the two-stage combustion. The results suggested that operating conditions controlled the magnitude and phasing of the two combustion events. Moreover, 3D CFD simulations of the metal engine configuration showed that the squish region contained an important mixture fraction that would burn much slower and can increase the phasing separation between the two combustion events to a point that a second peak would appear in the heat release rate. Moreover, the rapid-burn event in such an engine was much shorter compared to its traditional definition (i.e., the time in crank angle degrees between the 10% and 90%… Advisors/Committee Members: Cosmin E.
