▼ Since 1970, vehicle’s exhaust pollutions have received increasing attention as a source of air pollution at both local (human health concerns) and global (global warming) scales. This study mainly discusses diesel and gasoline vehicles because, today, over 90% of vehicles on the road use gasoline and diesel fuels. The major concerns of gasoline exhaust contaminants are carbon monoxide (CO), hydrocarbon (HC), carbon dioxide (CO₂) and polycyclic aromatic hydrocarbons (PAHs); the major concerns of diesel exhaust emissions contaminants are nitrogen oxides (NO_X) and particulate matter (PM). The aim of this study is mainly to compare gasoline and diesel fuels, and to determine which fuel and its developed forms are less harmful to humans, and which are most suitable for the natural environment at both a local and global level. The results show that burning gasoline fuels will emit less PM and NO_X emissions than burning diesel fuels, but it will generate about 50% more CO₂ than diesel fuels, and it also emit about ten times more CO, PAHs and around five times more HC than diesel fuels; burning diesel fuels will produce less CO₂ emissions than gasoline fuels, but will emit around ten times more NO_X and PM than gasoline fuels. Consequently using a gasoline car in urban areas might help to reduce the human health effects; using a diesel car on motorways or in rural areas might help to reduce the greenhouse gas (GHG) emissions and minimize the global warming effects. Biofuels, biodiesel and ethanol, have the potential to minimize the vehicle exhaust emissions and adverse effects. Nonetheless, there are still many debatable issues around biodiesel, such as insufficient fuel supply and health concerns (especially, ultrafine particles (UFPs)). In the future, there remains a need to continue the further studies of vehicle exhaust emissions, and to improve the understanding of all vehicle exhaust emissions and all of their impacts, especially the vehicle exhaust health research.

Mašinstvo - Motori sa unutrašnjim sagorevanjem / Mechanical engineering - Internal combustion engines

U ovom radu je proucavana mogucnost primene alternativnih biogoriva za pogon dizel motora sa direktnim ubrizgavanjem, kao i uticaj ovih goriva na proces sagorevanja i izduvnu emisiju ovog tipa motora. Kao alternativna biogoriva korišceni su metilestri ulja uljane repice, sojinog ulja i otpadnog jestivog palminog ulja. Ova biogoriva su korišcena kao cista (100%) ili u smeši sa standardnim dizel gorivom fosilnog porekla u odnosu 50:50 i u nekim uslovima i u smeši 25%, 50%, 75%. Takode, istražena je i mogucnost primene cistog jestivog rafinisanog suncokretovog ulja bez dodatne obrade ulja pre mešanja sa dizel gorivom u odnosu 50:50. Pored integralnih karakteristika motora: snage, obrtnog momenta, potrošnje usisnog vazduha i goriva, analize izduvnih gasova, protoka recirkulacije izduvnih gasova, snimljeni su tokovi pritiska u cilindru motora i vodu visokog pritiska sistema unrizgavanja i izdizanje igle brizgaca, korišcenjem akvizicionog sistema visokih performansi. Na bazi ovih velicina razvijen je i primenjen model za odredivanje parametara procesa sagorevanja. Koristeci ovaj postupak odredene su sledece karakteristike sagorevanja pri radu sa razlicitim biogorivima i pri razlicitim uslovima: vrednosti maksimalnog pritiska u cilindru motora kao i njihovi položaji u odnosu na SMT, zakoni oslobadanja toplote, periodi zakašnjenja upaljenja, trajanje sagorevanja i razvijene kolicine energije po fazama procesa sagorevanja. Takode je izvršeno ispitivanje uticaja svih korišcenih biogoriva na izduvnu emisiju motora. Istraživanja su vršena u usisnoj i natpunjenoj varijanti motora. Takode je detaljno istražen i uticaj recirkulacije izduvnih gasova na proces sagorevanja i izduvnu emisiju i to u obe varijante motora i sa svim korišcenim biogorivima. Poseban deo istraživanja se odnosio na mogucnost aplikacije komore za sagorevanje originalne konstrukcije sa smanjenim odavanjem toplote i uticaj ovog sistema sagorevanja na tok procesa sagorevanja i sastav izduvnih gasova. Dobijeni rezultati u okviru ovog rada se mogu koristiti pri optimizaciji radnog ciklusa dizel motora sa direktnim ubrizgavanjem u cilju postizanja povoljnije ekonomicnosti i izduvne emisije, pri pogonu biogorivima sa i bez recirkulacije izduvnih gasova.

ENGLISH ABSTRACT: Exhaust gas recirculation technology has been implemented with success in the automotive industry in reducing nitrogen oxides in diesel exhaust gas. Given that South Africa’s Clean Fuels programme currently adheres to Euro II fuel and emissions standards, research into the influence of exhaust gas recirculation on a more modern TDI engine running on locally sourced biofuel blends is done for this project. In this research project the existing engine test bench is upgraded by equipping the exhaust gas recirculation system as well as the compressor of the variable geometry turbocharger with various sensors and instrumentation. All the data acquired from the sensors is logged by a graphical user interface program developed in LabVIEW. National Instruments data acquisition devices USB 6351 and USB 4350 are interfaced with LabVIEW to obtain the recorded data. Further improvements include the addition of a water-to-air intercooler developed in-house to control the charge air temperature. An eddy current dynamometer replaces the previous hydraulic dynamometer to improve steady state speed and torque control of the engine. Experiments were performed on two biofuel blends, B20 and E10, using crude derived pump fuel as the base fuel. Both biofuel blends were splash blended and mixed by volume. The B20 blend consists of twenty percent biodiesel, obtained from waste cooking oil, and eighty percent base fuel. The E10 blend consists of ten percent ethanol mixed with the ninety percent base fuel. All fuels are refined locally. The control of the exhaust gas recirculation is maintained as per the original equipment manufacturer. The focus of this study is therefore to determine how exhaust gas recirculation affects a diesel engine optimised to run on ultra-low sulphur diesel and how it responds to running on different biofuel blends in terms of fuel consumption, temperatures and emissions of specifically nitrogen oxides. Results suggest that there is little to no variation in brake specific fuel consumption at the partial loads tested. The emission of nitrogen oxides does not deviate significantly between the fuels, however a marked reduction in soot is noticed for the E10 blend. Carbon monoxide concentrations are also higher for the E10 blend at high speed, low load operating points. As expected, nitrogen oxides are increased with the reduction in exhaust gas recirculation rate.

The present thesis, being in line with the present strict regulations set by the European Union regarding the increase in the use of energy from renewable sources and the reduction of pollutant emissions, as well as the stricter regulations discussed to be applied after 2020, aims to propose solutions towards the achievement of the EU’s goals, focused on the use of different types of biofuels. The thesis focuses on the evaluation of several alternative bio based fuels as substitutes of conventional diesel fuel, regarding the impact posed on the physicochemical properties of diesel, as well as the engine operation parameters and exhaust emissions. The goal is to increase the renewable character of petroleum-based fuels, by using large proportions of biofuels, and simultaneously achieve significant reductions of the pollutant exhaust emissions, without implementing modifications on the engine parameters.

▼ Since the transportation sector is a significant contributor of air pollution, the capabilities of estimating fuel use and emissions for various vehicles is important to air quality studies as well as the development of environmental guidelines and policy recommendations. In this thesis, a common or similar modeling approach based on second-by-second data using portable emission measurement system (PEMS) was developed to estimate energy and emission estimation for a wide variety of on-road and non-road sources with conventional and alternative technology. Based on vehicle-specific power (VSP) and speed-acceleration modal models, two correction factors were developed to estimate fuel consumption and emissions for vehicles which were driven with high and constant speed on highway. The corrected emission factors for NOx, HC, CO, and CO2 were significantly higher for high speeds and lower for low speeds than base emission factors estimated using MOBILE6 which is based on transient test cycles with durations on the order of 10 minutes. A similar methodology was used to estimate energy use and emissions for a plug-in hybrid diesel-electric school bus (PHSB) and conventional diesel school bus (CDSB) for typical school bus routes in NC. To quantify the reduction of fuel use and emissions between PHSB and CDSB for same driving routes, the mixed-modal models based on manifold absolute pressure and VSP versus emissions were developed. Plug-in hybrid technology showed significant emission reductions for stop-and-go driving pattern. These results could provide a support for transportation and air quality management. This thesis also introduces a simplified emission estimation methodology for locomotives based on rail-yard measurements using PEMS. This alternative measurement method is faster and cheaper than a federal reference method (FRM). The fuel-based emission rates based on PEMS measurement were comparable to FRM. It should serve as a useful basis of comparison to data in future measurement campaigns. Advisors/Committee Members: Donald R. van der Vaart, Committee Member (advisor), Nagui M.

▼ In occupational and public health there is a need for measurement and speciation of chemicals in ambient air to achieve control of air pollution and minimize health risks. In this work two methods of analysis are developed for the analysis of polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs) under ambient air conditions. Both methods involve the use of thermal desorption techniques with gas chromatography-mass spectrometry (GC-MS). For the measurement of polycyclic aromatic hydrocarbons (PAHs) airborne particulate samples are obtained by collection on small glass fibre filters. The volatile materials from these are thermally desorbed in two stages and transferred to a Gas Chromatograph-Mass Spectrometer analytical system. Results from studies of particulate samples obtained from sites in the region of Uxbridge, Middlesex are reported for eight selected polycyclic aromatic hydrocarbons (PAHs). Measurements on samples obtained directly from vehicle emission sources with the engine used under different running conditions are also reported. In the method of analysis of volatile organic compounds in air, samples are absorbed into 4mm Carbotrap 300 tubes and thermally desorbed and passed into a gas chromatography-mass spectrometry (GC/MS) or gas chromatography (GC) using helium as carrier gas. The Carbotrap absorbers used, show complete absorb/desorb reversibility, are thermally stable and do not react chemically with injected hydrocarbon standards. To demonstrate the value of the method analytical results obtained under ambient air conditions on the Brunel University campus (Uxbridge, Middlesex) are reported. Six selected low molecular weight aromatic hydrocarbons namely benzene, toluene, ethyl benzene and m-, p- and o-xylene are investigated in detail. The concentrations of these compounds were measured and results related to traffic flow rates and meteorological conditions to establish the fact that vehicle exhaust emissions are the main sources of the volatile organic compounds (VOCs) pollution at the collection sites. A study of volatile organic compounds (VOCs) levels in ambient air in Tehran (Iran) in which 55 hydrocarbons are identified is reported. A detailed study is made of the concentrations of the six hydrocarbons benzene, toluene, ethyl benzene and m-, p- and o-xylene because high concentrations of these pollutants can produce potential health problems. It is shown that the nature of the geographical location and the day time temperature play an important part in determining the composition of the mixture of pollutants in Tehran. Samples obtained directly from internal combustion engines with and without catalytic converters are also analysed using the method developed and the results show that there is a large depletion in aromatic hydrocarbons when toluene is reduced to a greater extent than benzene. The analytical method is also used to compare vehicle emissions from engines under cold start and hot start conditions.

▼ With the rapid development of modern aviation industry, how to make a balance between gradually increased aviation activities and the life quality of residents living within the vicinities of the airports becomes an increasingly prominent challenge. Research efforts have been made on single or multiple objective trajectory optimisations using gradient-based methods. Despite the effectiveness of the gradient-based methods, their applicability is limited by high standard requirements for problem formulation with smooth differentiable dynamics models and explicit expressions of optimisation objectives. An alternative option is using gradient-free algorithms capable of solving optimisation problems with discrete models, facilitating the integration of ''black box'' models that lack gradient information. However, the goals are generally achieved at the price of extensive computational burden. Moreover, adding further environmental parameters or different noise attributes, an optimal solution cannot be selected from the solution set obtained in the multi-objective optimisation problems, unless further algorithms are introduced. The present work focuses on the development of a multi-objective optimisation framework for departure and arrival aircraft to minimise multiple environmental impacts (noise and exhaust emissions). This framework includes a user-defined input module, a optimisation module, and flight perforemance module. The trajectory optimistaion module includes a set of of nonlinear models: aircraft dynamics, trajectory constraints and objective functions. A method to parameterise movement in the lateral plane based on a Bézier curve has been proposed to decrease the number of free parameters. The environmental objectives are modeled by a comprehensive flight mechanics programe FLIGHT and the ANP database from EUROCONTROL. Two posterior selection strategies based on a preference function and monetisation approaches are used to evaluate the resulting Pareto solution set. A simple single flight trajectory optimisation problem is identified and formulated as a multi-objective optimal control problem with a discontinuous problem formulation, solved by non-gradient algorithms. Among the three different non-gradient algorithms used, a non-dominated sorting genetic algorithm is identified as the most widely used method. However, two PSO-based multi-objective optimisers are explored to overcome some of the drawbacks of the GAs technique. Complex multiple flight events trajecotry optimisation problem is identified and formulated as a mixed-integer non-linear programming problem. A time-based separation rule is applied to approach the real flight assignment scenario. Finally, this application is conducted with a simple scenario to demonstrate its functionality. We demonstrate that this simulation framework is capable of solving trajectory optimisation problems with multiple simultaneous environmental objectives.

▼ The present doctoral thesis concerns the study of the physicochemical properties of fossil and alternative fuels and their mixtures, as well as the impact of alternative fuels (oxygenates and paraffinic fuels) on the exhaust emissions of a stationary diesel engine. Special emphasis has been placed on the development of mixing strategies of such alternative fuels and conventional diesel, with respect to their unique characteristics. The ultimate goal of this study was to investigate ways that can facilitate the integration of these alternative (and potentially renewable) components on fuel blends to be used in contemporary and future compression ignition engines, reducing exhaust emissions and dependence on fossil energy sources. The text is divided into 4 main parts. In the first part, basic knowledge is provided and the basic concepts of the dissertation are mentioned and explained, so that the reading of the text is as autonomous as possible without the need for the reader to constantly refer to other textbooks or writings. The first part also includes results and conclusions that have emerged from the international research effort during the last decades. The first part contains 4 chapters. •Chapter 1 is a basic introduction to crude oil and the basic properties of diesel fuel used in the transport sector. •Chapter 2 presents basic principles of combustion as well as basic mechanisms of pollutant formation in diesel engines. •Chapter 3 lists the reasons that have led to the development of research related to alternative and renewable fuels. A brief presentation of the alternative fuels used in the present thesis is also given. •Chapter 4 describes the structure of this research effort and presents the state of the art on the topic. The second part includes two chapters which present information about the experimental methodology and the equipment used for the completion of the present dissertation. •Chapter 5 presents all devices and their corresponding standard methods for measuring the physicochemical properties of fuels. •Chapter 6 presents in detail the experimental setup of the diesel engine housed in the Fuels and Lubricants Technology Laboratory of National Technical University of Athens, as well as the procedure for the measurement of exhaust emissions and fuel consumption. The third part includes the results of the experiments conducted during this research effort as well as comments on the findings. Due to the nature of the subject, the experimental process was completed over a period of about five years, during which changes in instrumentation, raw materials and reagents occurred, as is expected to happen in an active research laboratory. The results are presented per chapter as autonomous units. •Chapter 7 involves a preliminary study of the physicochemical properties of various conventional and alternative fuels covering a wide range of applications. Also, an equation to predict the ignition quality of marine distillates based on their physicochemical properties is developed. Finally, a comparative…

▼ The previous facility which was used for engine testing at Purdue's Ray W. Herrick Laboratories utilized an eddy current dynamometer which is only suited for steady-state testing and throttle snaps. To better utilize a pre-existing camless diesel engine, which is is enabled via variable valve actuation, it was desired to perform transient drive-cycle tests. To accomplish this goal, a variable frequency drive AC dynamometer was required. Given that a brand new facility was constructed, the team was presented with an opportunity for ground up design of a test cell. The new test cell's operation was proved out using a cammed diesel engine before moving the vairable valve actuation (VVA) enabled camless engine over. The research group's best practice is to only utilize the VVA engine when collecting novel or experimental data as additional run time on this engine increases the risk of damage due to valve-to-piston interference. The goal of proving out the test cell with the cammed engine was to validate that engine operation and data collection was ''as good as or better than" the previous test facility, and to solve any issues preventing the group from reaching that goal. Data acquisition results from the new test cell had noise issues which were worked out before moving over the VVA engine from the previous test cell. Fuel metering with a Cybermetrix fuel metering unit (FMU) proved to be more difficult than just plug and play, with fully functional and reliable operation taking place after the move. While the test cell's room ventilation proved fully functional, additional research and work was required to hook up the conditioned combustion air system. Transient drive-cycle testing was performed with the cammed engine, and statistical analysis was performed which confirmed that the feedback speed and torque matched the reference speed and torque within EPA guidelines. This same analysis was later performed with the VVA engine and also showed capability of the VVA engine to perform repeatable drive-cycle tests. The new test cell continues to see new additions, with future work including the installation and validation of a full diesel after-treatment system which will allow for research into improving not only engine-out emissions but also tailpipe emissions through studies of the dynamic interactions between the individual exhaust components. The scope of VVA enabled diesel engine research in the Cummins Power Lab has increased from steady-state testing to transient drive-cycle testing which is more representative of how the engine is used by the end-customers.

Kiekvienasis metais vis didėjant autotransporto kiekiui keliuose, didėja ir jų į aplinką išmetamų teršalų kiekiai. Todėl galime numanyti, jog Lietuvoje autotransportui išaugus 2,5 karto per paskutinį dešimtmetį tiek kartų išaugo ir į aplinką išmetamų kenksmingų deginių kiekiai, kurie labiausiai jaučiami didžiuosiuose miestuose ar miesteliuose. Greta Kelmės miesto yra keli dideli cheminės oro taršos šaltiniai: kelias Ryga-Kaliningradas, Kelmė – Raseiniai ir pagrindinė miesto sankryža, kur susidaro didžiausi teršalų kiekiai. Šiais keliais nuolat juda intensyvūs autotransporto srautai, kurių dalis patenka į Kelmės miestą. Todėl buvo atliktas autotransporto srautų įtakos Kelmės miesto aplinkos orui tyrimas: ištirti autotransporto srautai Kelmėje; išmatuota anglies monoksido kiekiai ore; teoriškai apskaičiuoti autotransporto amžiaus ir jo eksploatacinių parametrų įtaka deginių kiekiui ir jų sudėčiai; eksperimentiškai ištirta autotransporto cheminė tarša.

The volume of vehicle traffic, growing every year, increases the emissions of toxic substances and pollutes the environment. Consequently, the road traffic in Lithuania has increased by 2.5 times over the last decade. Big cities and small towns have noticed the effect of harmful exhaust emissions on the environment and people health most. A large number of chemical sources of air pollution are located near Kelme city: road Riga – Kaliningrad, Kelme – Raseiniai and the main city crossroads, which produces the most significant contaminants. These roads are constantly moving the intense flows of motor vehicles, the part of which falls within the town of Kelme. Therefore the aim of our research was to study the impact of the road traffic on the air quality in Kelme city, to investigate the traffic flows, to measure the concentration of carbon monoxide in the air, theoretically calculate the impact of vehicle age and its operating parameters on the exhaust emissions and its composition. The experimental research revealed the chemical pollution of the vehicles .

▼ The Proton Transfer Reaction Mass Spectrometer (PTR-MS) is a powerful tool for analyzing organic compounds in air and has been applied in field and laboratory applications to assess emissions from biomass burning and vehicles. Biomass burning is an important source of air pollution globally in the form of wild fires, burning of crop stubble, and combustion of organic material for home energy. In the United States, residential wood combustion combined with low inversion heights in winter time has caused air quality problems. Through field deployment of the PTR-MS in Xi’an China during August of 2011, it was determined that 27%, 16%, 26%, and 12% of ambient carbon monoxide (CO), acetaldehyde, benzene, and toluene could be attributed to biomass burning. The PTR-MS was also deployed to Yakima, Washington in January of 2013, finding that residential wood combustion was a substantial source of air toxics and PM. Residential wood combustion contributed 100%, 73%, 69%, 55%, 36%, 19%, 19%, and 17% of organic PM1, formaldehyde, acetaldehyde, black carbon, benzene, toluene, C2-alkylbenzenes, and CO respectively. Diesel vehicles are becoming a larger fraction of the vehicle fleet and can be held responsible for a substantial fraction of air pollution emissions from on and off road mobile sources. Diesel engines are a source of low volatility products that are difficult to measure and are thought to be important in the formation of secondary organic aerosol (SOA). This work focuses on measuring important diesel exhaust compounds with the PTR-MS and assessing oxidation processes of these compounds. When the PTR-MS was deployed to the field along with a thermal desorption preconcentration system, we estimated that diesel vehicles were about 3-15% of the vehicle activity influencing our study site in Yakima, WA using the ratio of m/z 157 to m/z 129. SOA yields of diesel exhaust compounds were assessed and about 48% of the SOA was attributed to compounds measured by the PTR-MS; with 21% attributed to alkylbenzenes, 20% attributed to alkanes, 3% attributed to alkylnaphthalenes, 3% attributed to molecular weight 178 polycyclic aromatic hydrocarbons, and 1% attributable to cycloalkanes.

▼ The overall objectives of this thesis were to investigate the potential of the peroxyoxalate chemiluminescence (POOL) reaction for the quantitative detection of target analytes in non-aqueous matrices and to compare quantitative performance with fluorescence detection. The target analytes investigated were polycyclic aromatic hydrocarbons (PAHs) and aliphatic amines. These were selected as an important class of compounds in engine exhaust emissions and a detergent additive in diesel fuel respectively. Chapter one outlines the challenges of analysing petroleum products and engine exhaust emissions and discusses the potential of luminescence techniques, particularly chemiluminescence (CL), for the quantification of trace components. The chapter also reviews the technique of flow injection (FT) as a means of sample delivery for CL detection and as a potential technique for field deployment. Liquid chromatography techniques are described as a means of separation of complex matrices, e.g. fuels and engine exhaust particulates, in the laboratory prior to CL detection. The luminescence properties of several PAHs were investigated in Chapter Two. Optimum excitation and emission wavelengths for eleven PAHs in four different solvents were determined using a batch fluorescence technique. A FI approach was used to determine PAH concentrations using fluorescence and POCL detection. Two aryl oxalates; bis(2,4-dinitophenyl)oxalate and bis(2,4,6-trichlorophenyl)oxalate were compared for their suitability for PAH determinations and an investigation of the key variables (e.g. concentration of aryl oxalate and hydrogen peroxide, mobile phase composition and pH) affecting POCL was performed. Recommendations for the optimum conditions for the determination of PAHs by POCL detection were determined, A comparison between a photodiode based detection device and a low power (12V) photomultiplier tube was also described. In Chapter Three the procedure of using POCL detection as a post column liquid chromatography (LC) detector for PAHs has been considered. The performance of the POCL detection system was compared with wavelength programmed fluorescence. Both reversed and normal phase LC was investigated and the suitability of POCL detection with each approach was discussed. Additionally the procedure for the LC separation and analysis of SRM 1649 (Urban Dust/Organics) and SRM 1650 (Diesel Particulate Matter) was described. The relative performance of fluorescence and CL detection are discussed. Chapter four describes the principles of multivariate calibration of spectrophotometric data, and three commonly applied techniques (PCR, PLSI and PLS2). Fluorescence data was obtained for synthetic mixtures of PAHs containing two, three, four and five components. A procedure whereby individual spectra were 'glued' together before undergoing data analysis has been developed and the results obtained discussed. POCL emission spectra for five PAHs were acquired using a two-dimensional charge coupled device (CCD). The sensitivity of the CCD system toward…

▼ This dissertation investigates the knock mitigation strategies and their experimental validation for improving performance and emissions with three different engine parameters: (i)Fuels (oxygenated fuel gasoline blends and syngas addition); (ii)Mixture dilution (EGR and Lean dilution); (iii)Injection strategies (DI and PFI combined dual fuel injection and multiple injections). Besides, a newly discovered unique relation between knocking and particulate matter emissions is examined in the last part with several conceptual models for better understanding of this phenomenon. The first part of this dissertation is about the effects of three oxygenated fuels (2,5-dimethylfuran, ethanol, and isobutanol) blended in gasoline on engine combustion, knock, and particulate matter emissions. One of the most promising furan functional group fuels, 2,5-dimethylfuran, is experimentally compared with two common alcohol-type oxygenates, ethanol and iso-butanol. Three major parameters are varied for the examination of oxygenates: fuel type, blend ratio, and boost level. The results show that the 2,5-dimethylfuran blends have the ability to extend knock limits as much as ethanol, but with relatively higher particulate matter emissions. As a second fuel study, syngas (hydrogen and carbon monoxide) aided engine combustion is experimentally investigated under EGR diluted and lean conditions by focusing on knock propensity, thermal efficiency, and emissions. Knocking tendencies are analyzed, and the thermal efficiency and emissions difference are discussed as well. The results show that with increasing the syngas addition, knocking is strongly suppressed, and the effect is more beneficial with EGR dilution than with air dilution. For the study of fuel injection strategies, two concepts of injection strategies are introduced and experimentally investigated. The first injection strategy is combined direct and port fuel injection to extend knock and EGR dilution limits using gasoline and ethanol fuels. The results showed that dual injection was beneficial to shorten the burn duration and improve combustion stability, but dual injection is slightly more sensitive to knock than direct injection primarily due to increased unburned gas temperature. The particulate matter emissions from dual injection were slightly lower, and the gaseous emissions showed lower total hydrocarbons and similar nitrogen oxides compared with only using direct injection of E20 fuel. The second fuel injection strategy involves multiple direct injections, which inject fuel multiple times in a cycle. This study explores the effect of multiple injections on knock, engine performance, particulate matter, and gaseous emissions. Two aspects of multiple injection strategies were experimentally investigated: the number of injections and the timing of the injections. The results confirm that multiple injection maintains torque and combustion stability but increases knock limits and thermal efficiency due to improved heat release phasing. The gaseous pollutant emissions including… Advisors/Committee Members: Boehman, Andre L (committee member), Raman, Venkatramanan (committee member), Lavoie, George A (committee member), Wooldridge, Margaret S (committee member).

Scope of the present thesis was to explore and evaluate advanced sampling and detection methods for the measurement of exhaust particles, and with these to investigate the technologies and operation conditions that affect exhaust particle emissions of modern vehicles. The sampling method evaluated is the "Catalytic Stripper", which is employed for the removal of volatile particles from exhaust aerosol. This method provides additional features over the conventional volatile removal systems for the measurement of solid particle number emissions according to the EU regulation. The study includes a thorough characterization of the device in the laboratory and evaluates its performance against reference instruments in exhaust PM applications. The Pegasor Particle Sensor (PPS) along with the "dual PPS" measurement concept comprise the particle detection methods explored in this study. The PPS, an aerosol instrument based on diffusion charging, was calibrated for exhaust particle number and mass emissions measurements, and evaluated in vehicle exhaust applications. Moreover, a new measurement concept, the dual-PPS, was developed for improved measurement accuracy, offering real-time mean particle size estimation. The above sampling and detection methods were then utilized to explore the effects of various parameters on exhaust PM emissions, including exhaust after treatment devices, engine type, ambient temperature, drive prole, and fuel save technologies.

Σκοπός της παρούσας διατριβής ήταν η μελέτη και αξιολόγηση προηγμένων μεθόδων δειγματοληψίας και ανίχνευσης για τη μέτρηση σωματιδιακών εκπομπών καυσαερίων από σύγχρονα οχήματα, και η εφαρμογή τους στη διερεύνηση των τεχνολογιών και παραμέτρων οι οποίες τις επηρεάζουν. Η μέθοδος δειγματοληψίας που αξιολογείται είναι ο Καταλυτικός Διαχωριστής, ένας καταλύτης μικρής κλίμακας με δυνατότητες οξείδωσης υδρογονανθράκων και αποθήκευσης θειικών συστατικών. Τα συγκεκριμένα χαρακτηριστικά δίνουν τη δυνατότητα εφαρμογής της συσκευής ως μεθόδου απομάκρυνσης πτητικών σωματιδίων, εναλλακτικής αυτής που ορίζει ο ισχύων ευρωπαϊκός κανονισμός για τη μέτρηση αριθμού στερεών σωματιδίων από κινητήρες και οχήματα. Η παρούσα μελέτη περιλαμβάνει τον λεπτομερή χαρακτηρισμό του καταλυτικού διαχωριστή στο εργαστήριο και αξιολόγηση της απόδοσής του σε τυπικές εφαρμογές μέτρησης. Οι μέθοδος ανίχνευσης σωματιδίων που μελετήθηκε είναι ο αισθητήρας «Pegasor Particle Sensor (PPS)». Η αρχή λειτουργίας του βασίζεται στην ηλεκτρική φόρτιση των σωματιδίων μέσω διάχυσης ιόντων. Ο αισθητήρας βαθμονομήθηκε και έπειτα αξιολογήθηκε σε εφαρμογές μέτρησης σωματιδιακών εκπομπών οχημάτων. Επιπρόσθετα, αναπτύχθηκε μια πρωτότυπη μέθοδος ανίχνευσης σωματιδίων, στην οποία δόθηκε η ενδεικτική ονομασία «dual PPS». Η μέθοδος αυτή δίνει τη δυνατότητα εκτίμησης του μέσου μεγέθους σωματιδίων, βάσει του οποίου μπορεί να γίνει ακριβέστερος υπολογισμός των σωματιδιακών συγκεντρώσεων. Μέσω της εφαρμογής των ανωτέρω μεθόδων δειγματοληψίας και μέτρησης, πραγματοποιήθηκε διερεύνηση των παραμέτρων οι οποίες επηρεάζουν τις…
