Available in PDF, EPUB and Kindle. Book excerpt: New regulations in the United States and Europe, designed to address climate change concerns by reducing greenhouse gas emissions, are causing increased use of gasoline direct-injection (GDI) engines in light-duty vehicles (LDV). Separate new regulations that aim to reduce particulate emissions to address air pollution concerns are taking effect concurrent with greenhouse gas limitations in both jurisdictions. GDI engines are proven to create more particulate emissions than previously utilized port-injection technology. Increasing particulate emissions rates combined with falling regulatory particulate emissions limits requires new strategies to reduce these emissions from gasoline powered LDVs. Particulate filters have been successfully implemented to reduce particulate emissions from diesel engine exhaust for over a decade. Diesel particulate filters have a demonstrated filtration efficiency of 95% or greater and have reduced diesel particulate mass (PM) emissions by one to two orders of magnitude. GDI engines require no more than one order of magnitude reduction in particulate emissions to meet new regulations. Existing particulate filter technology in use in diesel vehicles is capable of reducing GDI engine emissions to new regulatory levels; however, it is proposed that these reduction may be achievable through means other than gasoline particulate filters (GPF). A GPF will create an additional back-pressure in the engine exhaust system that will reduce engine power and efficiency. This backpressure will increase as PM is trapped in the filter and decrease as combustible PM removed. A buildup of incombustible ash present in engine-out PM will increase the baseline backpressure of the filter during the course of its service life. It is important to understand the impact of ash on the filter pressure drop performance before implementing GPF to meet new emissions regulations. This study builds on existing diesel particulate filter technology and demonstrates through experimental results the mechanisms by which ash increases GPF pressure drop. Ash deposits are also shown to increase the light-off temperature of three-way catalyst coatings in GPF.

This book was released on 2014 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stringent regulations worldwide will limit the level of particulate matter (PM) emitted from gasoline engines equipped with direct fuel injection. Gasoline particulate filters (GPFs) present one strategy for meeting PM limits over the full operating range of the engine. Over time these filters accumulate incombustible ash, increasing system pressure drop and adversely effecting engine performance. The effect of aging as a result of ash accumulation is examined over the full lifetime of gasoline particulate filters, using a novel accelerated aging system. This system utilizes a gasoline combustion chamber into which lubricating oil is injected simulating combustion in the power cylinder - the primary source of lubricant-derived ash. Advanced imaging techniques are used to characterize filter and particulate emission behavior, and compare to prior data from diesel filters of the same type. Likewise, pressure drop behavior is observed for multiple filter samples and compared to prior experiments. A collocated Gasoline Direct Injection engine was installed for comparative purposes; a method of testing engine performance with GPF installations was developed and the engine was prepared and instrumented for future testing. This report details the construction and validation of the accelerated aging system, examination and comparison of results to those from prior experiments, and confirmation of principal assumptions used in developing the experimental test matrix. This study is one of a very few completed in a unique, emerging field of study, driven by new and extremely stringent emissions regulations around the globe. Practical testing here lays the foundation for future detailed research into the behavior and application of particulate filters to gasoline fueled engines in light duty passenger vehicles.

Available in PDF, EPUB and Kindle. Book excerpt: 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 was released on 2013 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diesel particulate filters (DPF) are devices that trap hazardous particulate matter from diesel engine exhaust in order to meet increasingly strict particle emissions regulations. Diesel exhaust particulates mainly include soot and ash. Soot, carbon particles derived from incomplete fuel combustion, can be oxidized into carbon dioxide after being trapped by the DPF through a catalytic heating process called regeneration. Ash, however, derived from metallic additives in the engine lubricant required for robust engine operation, is an incombustible material and remains within the DPF following regeneration. As ash accumulates over time, exhaust airflow through the filter becomes restricted and an engine backpressure results. Engine performance and fuel economy are reduced, requiring the DPF to be cleaned or replaced. While the detrimental effects of ash on DPF performance and therefore fuel economy can be illustrated and quantified, there is much to be understood about the specific factors that govern ash properties like distribution, permeability, and morphology. Several different parameters, such as engine operating conditions and DPF design, have been found to significantly impact ash characteristics, and the ultimate goal is to be able to control these parameters to reduce detrimental ash effects to a minimum and improve DPF service life and performance. This work addresses the source of ash directly and investigates the effect of lubricant additive chemistry on ash characteristics and DPF performance. Three lubricant formulations, that differ only in the type of additives present, are tested and compared using a controlled, accelerated DPF loading system. Filter pressure drop response and resulting ash property data collected using an array of experimental and analytical techniques show that very little difference exists between the tested oils of differing additive content.

Up till now, we have received over three hundred papers from various countries; this shows that there has been a growing interest in the field of energy and power engineering. Among those papers received, we have eventually chosen about a hundred to be presented and included in this proceeding. These papers generally represented the current research status in this field and the future trend. We sincerely believe that these papers could be valuable to the future work of yours. Finally, on behalf of the committee, I would like to deeply express our gratitude to those who have supported the EPE2014, especially the international experts who helped reviewing papers, the DEStech Publications help publish the conference proceedings, and last but not least, the authors of these inspiring papers. Without the help from these people, EPE2014 would not be as half successful as it is now. Here, welcome to EPE2014 and let’s hope that it will be a great success. Tim Chou
