▼ The transportation sector has a significant impact on the environment both nationally and globally since it is a major vehicle fuel consumption and emissions contributor. These emissions are considered a major environmental threat. Consequently, decision makers desperately need tools that can estimate vehicle emissions accurately to quantify the impact of transportation operational projects on the environment. Microscopic fuel consumption and emission models should be capable of computing vehicle emissions reliably to assist decision makers in developing emission mitigation strategies. However, the majority of current state-of-the-art models suffer from two major shortcomings, namely; they either produce a bang-bang control system because they use a linear fuel consumption versus power model or they cannot be calibrated using publicly available data and thus require expensive laboratory or field data collection. Consequently, this dissertation attempts to fill this gap in state-of-the-art emission modeling through a framework based on the Virginia Tech Comprehensive Power-Based Fuel consumption Model (VT-CPFM), which overcomes the above mentioned drawbacks. Specifically, VT-CPFM does not result in a bang-bang control and can be calibrated using publicly available vehicle and road pavement parameters. The main emphasis of this dissertation is to develop a simple and reliable emission model that is able to compute instantaneous emission rates of carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) for the light-duty vehicles (LDVs) and heavy-duty diesel trucks (HDDTs). The proposed extension is entitled Virginia Tech Comprehensive Power-Based Fuel consumption and Emission Model (VT-CPFEM). The study proposes two square root models where the first model structure is a cubic polynomial function that depends on fuel estimates derived solely from VT-CPFM fuel estimates, which enhances the simplicity of the model. The second modeling framework combines the cubic function of the VT-CPFM fuel estimates with a linear speed term. The additional speed term improves the accuracy of the model and can be used as a reference for the driving condition of the vehicle. Moreover, the model is tested and compared with existing models to demonstrate the robustness of the model. Furthermore, the performance of the model was further investigated by applying the model on driving cycles based on real-world driving conditions. The results demonstrate the efficacy of the model in replicating empirical observations reliably and simply with only two parameters. Advisors/Committee Members: Rakha, Hesham A.

▼ 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.

▼ [EN] The automotive industry is currently experiencing one of its most rapidly changing periods in recent decades, driven by a growing interest in reducing the negative environmental impacts caused by fossil fuels consumption and the resulting carbon dioxide (CO2) emissions generated during the operation of the internal combustion engine (ICE) which have proven to contribute significantly to Global Warming. Given the fact that a total replacement of the current fleet, dependent of fossil fuels, is unlikely to happen in the immediate future and the urgency to reducing CO2 emissions from transportation in order to tackle Global Warming, it is possible to say that optimizing current ICE technologies and conventional vehicles and engines is a first order priority. Among the technical solutions developed to improve the efficiency of ICE, low viscosity engine oils (LVEO) have emerged as an effective and low-cost method that provides reductions in fuel consumption between 0.5% and 5%. During the development of this thesis, a test plan focused on determining fuel consumption reduction when low viscosity oils are used in light duty vehicles (LDV) and heavy duty vehicles (HDV) were carried out. The test plan has been divided in three parts; the first part was focused on the study of light-duty vehicles (LDV) using one diesel engine representative of the European market. During this part three testing modes were used: comparative motored, fired stationary points and transient homologation cycle tests. All test were performed in the engine test bed. The second part of the study consisted of another comparative test, this time using a different engine oils in a HDV fleet. The study was conducted using the urban buses fleet of the city of Valencia, including 3 buses models , with 2 different powertrain technologies. The third part of the study was focused on the friction coefficient behavior within the engine tribological pairs making comparative tests in two specialized tribometers; one of reciprocating action to simulate the lubrication conditions in the piston ring-cylinder liner contact and a "ball-on-disk" tribometer to simulate the lubrication in the distribution system. The various comparative studies have served to analyze how the friction and fuel consumption responded when LVEO were used both in the ICE and the complete vehicle contexts. The fuel consumption benefit found during the test was used to calculate the carbon footprint reduction when LVEO were used.; [ES] Actualmente la industria de la automoción vive uno de los periodos de cambio más vertiginosos de las últimas décadas, marcado por un creciente interés en reducir los impactos medioambientales negativos generados por el consumo de combustibles fósiles y sus consecuentes emisiones nocivas de dioxido de carbono (CO2) generados durante el funcionamiento del motor de combustión interna alternativo (MCIA).

▼ Development of a fuel economy model for light-duty and heavy-duty vehicles is part of the Texas Department of Transportation’s “Estimating Texas Motor Vehicle Operating Costs” project. A literature review for models that could be used to predict the fuel economy of light-duty and heavy-duty vehicles resulted in selection of coastdown coefficients to simulate the combined effects of aerodynamic drag and tire rolling resistance. For light-duty vehicles, advantage can be taken of the modeling data provided by the United States Environmental Protection Agency (EPA) for adjusting chassis dynamometers to allow accurate determination of emissions and fuel economy so that compliance with emissions standards and Corporate Average Fuel Economy (CAFE) regulations can be assessed. Initially, EPA provided vehicle-specific data that were relevant to a physics-based model of the forces at the tire-road interface. Due to some limitations of these model parameters, EPA now provides three vehicle-specific coefficients obtained from vehicle coastdown data. These coefficients can be related back to the original physics-based model of the forces at the tire-road interface, but not in a manner that allows the original modeling parameters to be extracted from the coastdown coefficients. Nevertheless, as long as the operation of a light-duty vehicle does not involve extreme acceleration or deceleration transients, the coefficients available from the EPA can be used to accurately predict fuel economy. Manufacturers of heavy-duty vehicles are not required to meet any sort of CAFE standards, and the engines used in heavy-duty vehicles, rather than the vehicles themselves, are tested (using an engine dynamometer) to determine compliance with emissions standards. Therefore, EPA provides no data that could be useful for predicting the fuel economy of heavy-duty vehicles. Therefore, it is necessary to perform heavyduty coastdown tests in order to predict fuel economy, and use these tests to develop vehicle-specific coefficients for the force at the tire-road interface. Given these coefficients, the fuel economy of a heavy-duty vehicle can be calculated for any driving schedule. The heavy-duty vehicle model developed for this project is limited to pre-2007 calendar year heavy-duty vehicles due to the adverse effects of emissions components that were necessary to comply with emissions standards that went into effect January 2007.

▼ The recognition of the negative impact of NOx resulted in increasingly tighter automotive emission regulations. Companies are under pressure to develop methods, which can meet the legislative demands. After treatment solutions, and especially Selective Catalytic Reduction, became the focus of research and have shown so far promising results. However, more in depth understanding of the SCR process under different conditions is needed. This thesis describes an investigation of the SCR performance using gas and urea injections under steady state and transient conditions undertaken on a light duty diesel engine using a 1D exhaust system designed for uniform flow across the catalyst. Under steady state conditions, the SCR performance was examined for low and high temperature conditions. Ammonia was supplied either as 5% ammonia gas or in form of urea injection. The engine was operating at 1500 rpm and 6 and 8 bar BMEP to provide an exhaust gas temperature of 210 °C and 265 °C respectively. Also, the effect of SCR brick length on the NOx conversion was investigated using SCR catalysts of length 30, 45 and 75 mm. To measure the influence of NO2:NOx ratio on the SCR performance, different sizes of standard DOC were used. NH3:NOx dosage levels included; α~0.5 - deficient ammonia, α~1.0 - stoichiometric ammonia, α~1.25 - excess ammonia. Gas emissions were measured before and after the SCR catalysts with a Horiba FTIR analyser during steady state and long transient tests. It was found that conditions such as temperature and NO2:NOx had the biggest impact on the SCR performance. During the steady state engine conditions, at α~1.0 ammonia dosing and NO2:NOx ratio of 0, only 17% of NO was converted in the first 30 mm of the SCR brick length. The conversion was improved at high temperature (263 °C) to 31%. A fast response CLD analyser was used during short transient testing to sample emissions with a high resolution. The short transient test with standard 0.5 and 1 DOC, and fixed ammonia dosing, showed that NOx conversion was reduced during the ramp event due to deficient ammonia and a drop in the supplied NO2:NOx ratio. During urea injection experiments, urea was injected either through an oblique pipe arrangement with a mixer device placed downstream or directly into a mixing can. In this case the mixer device was replaced with a straight pipe. A 75mm SCR was fitted and to ensure that supplied NO2:NOx ratio was zero, a palladium only DOC was used post a DPF. It was found that a large proportion of urea decomposition and hydrolysis was occurring on the surface of the SCR catalyst. Comparing NOx performance between urea injection and ammonia gas dosing experiment, more NO was converted for a given NH3:NOx ratio when ammonia was supplied in the form of gas. That was true for low and high temperature tests. For most studies, a long 10 degree diffuser was used in front of the SCR to provide uniform gas distribution across the catalyst. In addition SCR performance was investigated with a 180 degree sudden expansion diffuser in order to…

▼ A key element to the success of the internal combustion engines (ICE) is to take advantage of the thermal energy contained in the exhaust gases from the combustion cycle to minimize harmful exhaust emissions, improve fuel economy and prolong engine life. Also, taking advantage of the waste heat to maintain the engine to the correct operating temperature, will potentially reduce fuel usage during warm-up periods and can reduce harmful tailpipe emissions at cold starts. Therefore, having the ability to achieve significant reductions in harmful pollutants, such as carbon monoxide (CO), hydrocarbons (HC), Particulate matter (PM) and greenhouse gases (GHG), and other complex pollutants makes thermal energy storage devices an attractive technology to achieve this goal. Also, to drastically, reduce fuel consumption the development of thermal energy storage (TES) using solid-liquid phase change materials, it seems to be a viable economic short-term solution to exploit ICE capabilities. For example, a cold start engine generates about 60,000 ppm of CO while the catalytic converter is reaching its average operating temperature, generally above 300 C. These values depend on the health and age of the engine. Also, idling an engine reduces fuel economy in order of >6% according to the fuel economy EPA emissions test model. For this thesis work and experimental analysis was calculated on a light-duty vehicle (LDV) or class 1(<6000 lb) category. The analyzed results on emissions on a four-cylinder selected engine are exclusively for estimate calculations of the overall potential fuel economy as a result of integrating a thermo-energy storage system. The analysis shows the potential advantages of thermo-energy devices in terms of fuel savings and tailpipe emissions. Additionally, a cost-benefit analysis will show potential fuel savings over time.

Depuis plusieurs années les chiffres de l'insécurité routière montrent la nécessité de développer un outil technologique qui vise à connaitre le comportement de véhicules deux roues motorisés (2RM) afin d'améliorer leursécurité. De cette problématique découle nos travaux de recherche qui s'inscrivent dans le cadre de projet METRAMOTO (MEsure du TRAfic des deux-roues MOTOrisés pour la sécurité routière et l'évaluation des risques)L’objectif principal visé concerne la modélisation, le dimensionnement et l'optimisation d'un capteur hybride constitué d'une part de boucles électromagnétiques et d'autre part de capteurs de chocs piézo-électriques. L’idée consiste à utiliser les boucles électromagnétiques pour discriminer la présence des 2RM de celle des autresvéhicules, associées à des segments piézo-électriques pour détecter le choc produit par le passage des roues desdifférents véhicules, le tout associé à un algorithme de gestion et de traitement de données. Aujourd'hui redimensionnement des systèmes de détection à base de boucles électromagnétiques ou de câble piézo-électriquese fait de manière expérimentale sur des sites contrôlés en utilisant plusieurs types de véhicules. Cette technique gourmande en temps nécessite une série importante d'essais couteux et dangereux. La présente étude a pour butde modéliser les différentes interactions entre le capteur hybride étudié et les véhicules en vue de son dimensionnement. Des modèles électromagnétiques et électromécaniques sont développés pour décrire les différentes interactions se produisant entre les boucles électromagnétiques d'une part, les boucles électromagnétiques et les véhicules d'autre part ainsi que celles des roues de véhicules et le câble piézoélectrique.Sur la base de ces modèles établis, une démarche générale est élaborée conduisant au dimensionnement du capteur hybride pour une route donnée. Nous nous sommes également intéressés au traitement des données issues du capteur hybride pour lesquelles nous proposons une approche d'identification des différentes catégories de véhicules dont les 2RM. Deux configurations de capteurs pour deux routes différentes sont alors proposées.Elles sont associées à des algorithmes de traitement de données permettant l'acquisition des signaux de boucles et de câbles, la distinction des différents types de véhicules, l'estimation de la position des véhicules sur la chaussée ainsi que la mesure de la vitesse de véhicules.

▼ This work seeks to define methodologies and techniques to analyze automotive fleet-tracking big data and provide sample results that have implications to the real world. To perform this work, vehicle fleet-tracking data from Odyne and Via Plug-in Hybrid Electric Trucks collected by the Electric Power Research Institute (EPRI) was used. Both CAN-communication bus signals and GPS data were recorded off of these vehicles with a second-by-second data collection rate. Colorado State University (CSU) was responsible for analyzing this data after it had been collected by EPRI and producing results with application to the real world. A list of potential research questions is presented and an initial feasibility assessment is performed to determine how these questions might be answered using vehicle fleet-tracking data. Later, a subset of these questions are analyzed and answered in detail using the EPRI dataset. The methodologies, techniques, and software used for this data analysis are described in detail. An algorithm that summarizes second-by-second vehicle tracking data into a list of higher-level driving and charging events is presented and utility factor (UF) curves and other statistics of interest are generated from this summarized event data. In addition, another algorithm was built on the driving event identification algorithm to discretize the driving event data into approximately 90-second drive intervals. This allows for a regression model to be fit onto the data. A correlation between ambient temperature and equivalent vehicle fuel economy (in miles per gallon) is presented for Odyne and it is similar to the trend seen in conventional vehicle fuel economy vs. ambient temperature. It is also shown how ambient temperature variations can influence the vehicle fuel economy and there is a discussion about how changes in HVAC use could influence the fuel economy results. It is also demonstrated how variations in the data analysis methodology can influence the final results. This provides evidence that vehicle fleet-tracking data analysis methodologies need to be defined to ensure that the data analysis results are of the highest quality. The questions and assumptions behind the presented analysis results are examined and a list of future work to address potential concerns and unanswered questions about the data analysis process is presented. Hopefully, this future work list will be beneficial to future vehicle data analysis projects. The importance of using real-world driving data is demonstrated by comparing fuel economy results from our real-world data to the fuel economy calculated by EPA drive cycles. Utility factor curves calculated from the real-world data are also compared to standard utility factor curves that are presented in the SAE J2841 specification. Both of these comparisons showed a difference in real-world driving data, demonstrating the potential utility of evaluating vehicle technologies using the real-world big data techniques presented in this work.

▼ The following document highlights the successful development of a scientifically-based approach for creating diesel engine combustion that yields lower levels of nitric oxide (NO_x) and particulate matter (PM) emissions while minimizing the associated fuel consumption penalty and raised levels of hydrocarbon (HC) and carbon monoxide (CO) emissions. The 93% reduction in NO_x, coupled with the simultaneous 79% reduction in PM places the newly developed engine calibration within the emission targets established for this research development. The primary distinguishable features of this strategy are premixed and low-temperature combustion. Both characteristics shift combustion to a region where simultaneous reductions in NO_x and PM occur, thus defeating the perennial PM-NO_x tradeoff associated with conventional diesel combustion. The increase in fuel consumption, 5% over the studied conventional combustion strategy, could possibly be recovered in part through optimal development of the engine system from the turbocharger to the combustion chamber design. The new combustion development approach opens an opportunity to run the diesel engine rich of stoichiometric air-fuel ratios, while maintaining near-zero EI-PM emissions. Exhaust concentrations of CO as high as 5% emitted from the rich diesel condition create enough of the reducing agent necessary for an aggressive regeneration of a NO_x storage aftertreatment device. The rise in fuel consumption, greater than that associated with the newly developed lean combustion strategy, prevents this condition from usefully serving as a standard operating mode; its intention is to operate only as necessary to maintain high NO_x removal efficiency. Related to this, the 99% reduction in NO_x and 98% reduction in PM – relative to the studied conventional diesel combustion strategy – assist in preventing PM and NO_x interference during the regeneration of a NO_x storage device. Increased levels of HC and CO species result as diesel combustion burns in the new premixed, low-temperature fashion. A diesel oxidation catalyst (DOC) was studied to determine its ability to remove the higher levels of HC and CO species associated with the newly developed combustion strategies. The catalyst-out concentrations of emissions produced from the newly developed lean strategy lessen such that all emissions, i.e. NO_x, PM, CO, and HC, satisfactorily meet the most stringent of upcoming federal emission regulations, at the studied engine speed and load. However, this study postulates that dramatic reductions in combustion temperature at the newly developed rich strategy alter HC species, which thereby completely quench the oxidation activity of the DOC. An increase of 100°C in exhaust temperature or an increase of exhaust oxygen concentration to 2% of total exhaust volume at the rich strategy does not improve the DOC's ability to remove HC or CO.

Det här projektet handlar om att utveckla en metod för real driving emission (RDE). RDE är ett komplement till Worldwide Light Duty Test Procedure (WLTP) som kommer att ersätta New European Driving Cycle (NEDC). Dessa cykler och metoder används för att mäta personbilars avgaser. Huvudanledningen till varför NEDC ska bytas ut är för att körcyklerna inte längre är realistiska och reflekterar inte hur en bil presterar egentligen. Detta har lett till att bilar har högre bränsleförbrukning och högre avgasutsläpp när dom körs i trafiken jämfört med resultaten från NEDC.Metoden utvecklades genom hänvisningar till den officiella WLTP rapporten. Tillsammans med Vehicle Emission gruppen från AVL fastställdes en komplett steg för steg metod.Utrustningen som användes förseddes av AVL och flera tester av varje steg av metoden genomfördes för att förfina metoden så mycket som möjligt. Bilen som användes var en SAAB 9-5 2.0l bensin.Resultaten visade att både bilen och testet inte mötte kriterierna för RDE och godkändes inte av programmet som användes för att utvärdera testet. Detta var delvis för att kriterierna för RDE är strikta och delvis för att ingen pre och post test genomfördes eftersom det tar mycket tid för att dom testerna ska bli godkända.I överlag ger WLTP och RDE potentiella bilköpare en bättre detaljerad sammanfattning av hur bra bilen presterar i trafiken jämfört med NEDC.

This project is about developing a method for real driving emission (RDE). RDE is a complement to Worldwide Light Duty Test Procedure (WLTP) which will replace the New European Driving Cycle (NEDC). These cycles and procedures are used for measuring emissions for light duty vehicles. The main reason why NEDC is being replaced is because the driving cycles does not reflect how vehicles are normally driven. This has resulted in vehicles having higher fuel consumption and emitting more poisonous gases when driven on actual roads compared to the results from the NEDC.The method was developed by referring to the laws of the official WLTP report written by EU. Together with the Vehicle Emissions team at AVL a complete step by step method was established.All the equipment and instruments were provided by AVL and several tests of each step of the method was made to perfect the method as much as possible. The vehicle that was used was a 2005 SAAB 9-5 2.0l petrol.The results displayed that the car and the test did not meet the criteria for RDE and was not passed by the evaluating software. This was partly because the driving criteria for RDE are strict and can be difficult to achieve and partly because no pre and post test was made since it can take several tries before those tests are passed.Overall, WLTP and RDE give buyers a more detailed and better conclusion of how a car performs on the road compared to NEDC.

▼ The number concentration and size distribution of particles in Brisbane have been studied extensively by the researchers at The International Laboratory for Air Quality and Health, Queensland University of Technology (Morawska et al., 1998, 1999a, 1999b). However, the comprehensive studies of chemical compositions of atmospheric particles, especially with regard to the two main classes of pollutants (polycyclic aromatic hydrocarbons and trace elements), that are usually of environmental and health interest, have not been fully undertaken. Therefore, this thesis presents detailed information on polycyclic aromatic hydrocarbons (PAHs) and elemental compositions of vehicle exhausts and of urban air in Brisbane. The levels of polycyclic aromatic hydrocarbons (PAHs) and elements in three of Brisbane's urban sites (Queensland University of Technology, Woolloongabba and ANZ stadium sites) were measured. The most common PAHs found in all sites were naphthalene, phenanthrene, anthracene, fluoranthene, pyrene and chrysene while Al, Cd, Co, Cr, Cu, Fe, Mn, Mo, Si, Sn, Sr and Zn were the most common elements detected in the total suspended particles and fine particle (PM2.5). With the aid of multivariate analysis techniques, several outcomes were obtained. For example: – Major human activities such as vehicular and industrial sources were the most contributing pollution sources in Brisbane. However, these two sources have different influential strength on the compositions of the polycyclic aromatic hydrocarbons and trace inorganic elements found in the urban air. – Woolloongabba bus platform was the most polluted site on the basis of the elemental and PAH compositions in its air samples while QUT site was the worst polluted site in terms of PM2.5 elemental contents. These results demonstrated that the impact of traffic related pollutants on Brisbane's urban air is significant. This led to the investigations of the direct emissions of pollutants from exhaust vehicular source in the second part of this research work. The exhaust studies included the investigations of PAHs, trace inorganic elements and particles. At the time of the study, the majority of vehicles in Brisbane used low sulfur diesel (LSD) fuel or unleaded petrol (ULP). However, the importance of vehicles using ultra low sulfur diesel (ULSD) and liquefied petroleum gas (LPG) is constantly growing. Therefore, the exhaust emission studies on chassis dynamometer from heavy duty non-catalyst-equipped buses powered by LSD and ULSD with 500 ppm and 50 ppm sulfur contents respectively as well as passenger cars powered by ULP and LPG were explored. The outcomes of such studies are summarized as follows: – Naphthalene, acenaphthene, acenaphthylene, anthracene, phenanthrene, fluorene, fluoranthene and pyrene were frequently emitted by the buses powered by LSD and ULSD. However, buses powered by ULSD emitted 91% less PAHs than those powered by LSD. On the other hand, Mg, Ca, Cr, Fe, Cu, Zn, Ti, Ni, Pb, Be, P, Se, Ti and Ge were found in measurable…
