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.

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 Ministry of Environment and Climate Change (MOECC) found that black carbons (BC) concentrations were significantly higher in summer than in winter, which could be attributed to the seasonal variations in fuel composition. This experimental study investigated the impact of fuel seasonal changes on particulate matter (PM) emissions using a Ford Focus wall-guided GDI engine. Fuels from five public gas stations having octane rating of 87 and 91 were analyzed and tested. This study demonstrated that summer fuels contained higher aromatics than winter fuels which led to higher PM emissions and BC concentrations during steady state and transient state conditions. Moreover, the removal of ethanol content resulted in lower PM emissions and BC concentrations during steady state conditions. This study suggested that an increase in aromatics in summer fuels could be root cause for higher BC concentrations, however, similar study should be performed in other engines to support this conclusion.

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.

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.
