This thesis discusses experimental investigations to reduce particle number emissions from gasoline engines with direct injection. Measures on a single cylinder research engine with combined usage of a particle number measurement system, a particle size distribution measurement system as well as optical diagnostics and thermodynamic analysis enable an in-depth assessment of particle formation and oxidation. Therefore, numerous optical diagnostic techniques for spray visualisation (Mie-scattering, High-Speed PIV) and soot detection (High-Speed-Imaging, Fiber optical diagnostics) are deployed. Two injectors with different hydraulic flows but identical spray-targeting are characterised and compared by measurements in a pressurised chamber. The operation at higher engine load and low engine speed is in the focus of the experimental work at the engine test bench. Thereby, the low flow velocities in the combustion chamber, caused by the low engine speed, as well as the large amount of fuel injected are major challenges for the mixture formation process. A substantial part of the thesis thus focusses on the detailed analysis of the mixture formation process, which is consisting of fuel injection, interaction of the in-cylinder charge motion with the fuel injected and the fuel properties. Measures for the optimisation of the mixture formation process and the minimisation of the particle number emissions are analysed and evaluated. The charge motion is manipulated by the impression of a directed flow, the variation of the valve timings and valve open curve. The injection process is influenced by a reduction of the hydraulic flow of the injector and an increase of the injection pressure up to 50 MPa. The investigations show fundamental effects and potentials of different variation parameters concerning their emissions reduction potential at the exemplary operation at high engine load. Due to the simultaneous analysis of the in-cylinder charge motion and a thermodynamic analysis, the results can be transferred to different engines.

For years, diesel engines have been the focus of particulate matter emission reductions. Now, however, modern diesel engines emit less particles than a comparable gasoline engine. This transformation necessitates an introduction of particulate reduction strategies for the gasoline-powered vehicle. Many strategies can be leveraged from diesel engines, but new combustion and engine control technologies will be needed to meet the latest gasoline regulations across the globe. Particulate reduction is a critical health concern in addition to the regulatory requirements. This is a vital issue with real-world implications. Reducing Particulate Emissions in Gasoline Engines encompasses the current strategies and technologies used to reduce particulates to meet regulatory requirements and curtail health hazards - reviewing principles and applications of these techniques. Highlights and features in the book include: Gasoline particulate filter design, function and applications Coated and uncoated three way catalyst design and integration Measurement of gasoline particulate matter emission, both laboratory and PEMS The goal is to provide a comprehensive assessment of gasoline particulate emission control to meet regulatory and health requirements - appealing to calibration, development and testing engineers alike.

This book focuses on particulate matter emissions produced by vehicles with combustion engines. It describes the physicochemical properties of the particulate matter, the mechanisms of its formation and its environmental impacts (including those on human beings). It discusses methods for measuring particulate mass and number, including the state-of-the-art in Portable Emission Measurement System (PEMS) equipment for measuring the exhaust emissions of both light and heavy-duty vehicles and buses under actual operating conditions. The book presents the authors’ latest investigations into the relations between particulate emission (mass and number) and engine operating parameters, as well as their new findings obtained through road tests performed on various types of vehicles, including those using diesel particulate filter regeneration. The book, which addresses the needs of academics and professionals alike, also discusses relevant European regulations on particulate emissions and highlights selected methods aimed at the reduction of particulate emissions from automobiles.

With the signing of the Paris Agreement in December 2015 the United Nations explained their willingness to limit the GHG Emissions and contribute to the measures against the global warming effect. In 2019 the European Commission proposed the Green Deal and as a consequence the target to be climate neutral in 2050. In consequence the fossil based energy system has to transform into a climate-neutral energy system with renewable and sustainable energy carriers. Research on and development of alternative fuels and new production processes are ongoing to provide the technical solution. Political actions are needed to provide the economic framework for the introduction of such alternative fuel solutions. The fulfilment of the European CO2 reduction targets until 2050 needs realistic technical solutions including backwards compatible approaches for existing vehicle fleets. An economic and sustainable development towards climate neutral mobility requires a holistic view based on life cycle assessments for the different mobility approaches including the economic impacts as well as financing options. A synergetic discussion of solutions for future fuels and powertrain technologies is needed to develop an economic pathway to a sustainable and affordable mobility of tomorrow. The challenging goal for mobility can only be achieved through an international cooperation of universities, the automobile industry, energy producers, the oil industry and the legislative bodies of the member states. The international colloquium aims to contribute to the development of a climate-neutral mobility by exchanging views on and discussing all aspects connected with the "powertrain/fuel/environment" system, including the necessary political regulations.

Due to both potential climate and health concerns, research interest in the formation of particulate matter in GDI engines remains strong. However, the processes driving the emissions are still not fully understood. This experimental study investigated the influence of fuel volatility on the particulate matter emissions, using both commercial and specifically targeted and controlled surrogate fuel blends to isolate the influence of fuel volatility from traditionally considered causative effects of fuel chemistry and properties. In non-ethanol containing fuels, high measured volatility fuels resulted in increased PM emissions in comparison to low volatility fuels, while also generating increased nitric oxide emissions. The effect of 10\% ethanol match blended in these fuels varied with volatility level, with E10 fuels always presenting high PM emissions, unlike their ethanol-free counterparts. A fuel injector deposit driven change in PM emissions was noted in the dataset, which appeared to show dependence on fuel volatility as well.

The public health risks posed by automotive particulate emissions are well known. Such particles are sufficiently small to reach the deepest regions of the lungs; and moreover act as carriers for many potentially toxic substances. Historically, diesel engines have been singled out in this regard, but recent research shows the need to consider particulate emissions from gasoline engines as well. Already implicated in more than one respiratory disease, the strongest evidence in recent times points to particle-mediated cardiovascular disorders (strokes and heart attacks). Accordingly, legislation limiting particulate emissions is becoming increasingly stringent, placing great pressure on the automotive industry to produce cleaner vehicles - pressure only heightened by the ever-increasing number of cars on our roads. Particulate Emissions from Vehicles addresses a field of increased international interest and research activity; discusses the impact of new legislation globally on the automotive industry; and explains new ways of measuring particle size, number and composition that are currently under development. The expert analysis and summary of the state-of-the-art, which encompasses the key areas of combustion performance, measurement techniques and toxicology, will appeal to R&D practitioners and engineers working in the automotive industry and related mechanical fields, as well as postgraduate students and researchers of engine technology, air pollution and life/ environmental science. The public health aspects will also appeal to the biomedical research community.

Particulate emissions from gasoline direct injected engines are a topic of growing research interest due to health concerns. Using engine tests of extended length and fueled with custom hydrocarbon blends, this study aimed to experimentally investigate temporal and test-to-test gasoline particulate emissions variability that has been observed in earlier work. Gasoline property changes during engine operation and engine control module adjustments were ruled out as the source of the temporal variation. Crankcase ventilation system deposits were also ruled out but they were found to increase average particle numbers. Testing of custom fuel blends demonstrated that transient cold and hot start particulate emissions are fuel independent, steady state emissions are highly influenced by fuel properties and the commonly used model to assess that influence, the PM Index, is incomplete, and that the use of fuel of consistent composition reduces test-to-test variability.
