This book was released on 2013-04-17 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second book edited with a selection of papers from the two-yearly THIESEL Conference on Thermo- and Fluid Dynamic Processes in Diesel Engines, organised by CMT-Mvtores Termicos of the Universidad Po/itecnica de Valencia, Spain. This volume includes versions of papers selected from those presented at the THIESEL 2002 Conference th held on lOth to 13 September 2002. We hope it will be the second volume of a long series reflecting the quality of the THIESEL Conference. This year, the papers are grouped in six main thematic areas: State of the Art and Prospective, Injection Systems and Spray Formation, Combustion and Emissions, Engine Modelling, Alternative Combustion Concepts and Experimental Techniques. The actual conference covered a wider scope of topics, including Air Management and Fuels for Diesel Engines and a couple of papers included reflect this variety. However, the selection of papers published here represents the most current preoccupations of Diesel engine designers, namely how to improve the combustion process using new injection strategies and alternative concepts such as the Homogeneous Charge Combustion Ignition.
Download or read book Particulate Emissions from Vehicles written by Peter Eastwood and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Clearly the reduction of NOx and particulate emissions remains a major challenge to Diesel engine manufacturers due to increasingly stringent emission standards in the US and other countries. The well documented NOx/particulate trade-off observed in Diesel engines makes the simultaneous reduction of both emissions particularly difficult for manufacturers to achieve. In an effort to provide an improved understanding of the fundamental processes which result in this trade-off, a program was carried out at Penn State to develop the appropriate engine facilities and laser diagnostics to permit in-cylinder studies of Diesel combustion and emissions production with the support of the Department of Energy Advanced Industrial Technology Division . This work has also been supported by the Cummins Engine Company, Lubrizol Corporation and the National Science Foundation. An optically accessible, direct injection, Diesel engine was constructed for these studies. The major objective of the, design of the engine was to maximize optical access under conditions representative of Diesel engine combustion in small bore, commercial engines. Intake air is preheated and boosted in pressure to make the in-cylinder conditions of heat release and pressure as realistic as possible. Another important objective of the design was flexibility in combustion chamber geometry to permit a variety of head and bowl geometries to be studied. In all the results reported in this report a square bowl was used to simplify the introduction of laser light sheets into the engine.

This book was released on 1993 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional (2-D) laser-sheet imaging has been used to examine the soot and liquid-phase fuel distributions in a newly designed, optically accessible, direct-injection Diesel engine of the heavy-duty size class. The design of this engine preserves the intake port geometry and basic dimensions of a Cummins N-series production engine. It also includes several unique features to provide considerable optical access. Liquid-phase fuel and soot distribution studies were conducted at a medium speed (1,200 rpm) using a Cummins closed-nozzle fuel injector. The scattering was used to obtain planar images of the liquid-phase fuel distribution. These images show that the leading edge of the liquid-phase portion of the fuel jet reaches a maximum length of 24 mm, which is about half the combustion bowl radius for this engine. Beyond this point virtually all the fuel has vaporized. Soot distribution measurements were made at a high load condition using three imaging diagnostics: natural flame luminosity, 2-D laser-induced incandescence, and 2-D elastic scattering. This investigation showed that the soot distribution in the combusting fuel jet develops through three stages. First, just after the onset of luminous combustion, soot particles are small and nearly uniformly distributed throughout the luminous region of the fuel jet. Second, after about 2 crank angle degrees a pattern develops of a higher soot concentration of larger sized particles in the head vortex region of the jet and a lower soot concentration of smaller sized particles upstream toward the injector. Third, after fuel injection ends, both the soot concentration and soot particle size increase rapidly in the upstream portion of the fuel jet.

This book was released on 1994 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the work performed during the contract period was to establish the ability to study soot and NO within the combustion chamber of a DI Diesel engine and to couple these measurements with actual exhaust emissions. This work was motivated by the need to obtain a more complete understanding of the particulate/NO{sub X} trade-off, observed in Diesel engines, to aid engine designers in meeting emissions limits. In order to achieve the desired goal, an optically accessible DI Diesel engine was designed and constructed. Also, planar imaging methods for imaging soot and NO were developed in laboratory flames and were then applied to the engine. For the study of soot, planar Mie scattering was used and a polarization ratio method was investigated to distinguish soot from fuel droplets. The Mie scattering technique proved to be well suited for the engine, and extensive results were obtained. In order to observe NO, planar laser induced fluorescence was used and it was successfully applied in the engine. In addition to these techniques, high speed combustion photography and shadowgraph photography were applied to obtain general characteristics of the combustion process. As a final diagnostic, actual engine emissions were measured. This report begins with a brief discussion of the problem under investigation and a summary of other studies of the NOx/particulate trade-off. Following these sections is a summary of the accomplishments and results from the present study. Finally, detailed results are presented through the six technical papers which were written during the contract period; these papers are appended to the report.
