This is part two of two volumes detailing the results of a program designed to develop a combustion system for low-emission natural gas engines. It focuses on the design and investigation of a fast-burn combustion chamber. It is known that the level of turbulence in the chamber just prior to ignition and during combustion has an important impact on the burning rate of the air-fuel mixture. The level of turbulence in the chamber can be influenced by the chamber design through the degree of swirl imparted to the mixture during the intake process and by the squish motion generated as the piston nears the top dead centre. The volume describes research conducted to determine experimentally the relationship between the intake and compression generated charge motions of squish and swirl on engine performance and emissions. The work included design and construction of a variable swirl intake port and a swirl meter, wide-open throttle testing of squish and swirl combinations, and part load testing at constant volumetric flow rates. An optimum squish-swirl operating condition was determined.

Lean Combustion: Technology and Control, Second Edition outlines and explains the latest advances in lean combustion technology and systems. Combustion under sufficiently fuel-lean conditions can have the desirable attributes of high efficiency and low emissions. The book offers readers both the fundamentals and latest developments in how lean burn (broadly defined) can increase fuel economy and decrease emissions, while still achieving desired power output and performance. This volume brings together research and design of lean combustion systems across the technology spectrum in order to explore the state-of-the-art in lean combustion. Readers will learn about advances in the understanding of ultra-lean fuel mixtures and how new types of burners and approaches to managing heat flow can reduce problems often found with lean combustion (such as slow, difficult ignition and frequent flame extinction). This book offers abundant references and examples of real-world applications. New to this edition are significantly revised chapters on IC engines and stability/oscillations, and new case studies and examples. Written by a team of experts, this contributed reference book aims to teach its reader to maximize efficiency and minimize both economic and environmental costs. - Presents a comprehensive collection of lean burn technology across potential applications, allowing readers to compare and contrast similarities and differences - Provides an extensive update on IC engines including compression ignition (diesel), spark ignition, and homogeneous charge compression ignition (HCCI) - Includes an extensive revision to the Stability/Oscillations chapter - Includes use of alternative fuels such as biogas and hydrogen for relevant technologies - Covers new developments in lean combustion using high levels of pre-heat and heat recirculating burners, as well as the active control of lean combustion instabilities

Twentyfour years have gone by since the publication of K. Lohner and H. Muller's comprehen sive work "Gemischbildung und Verbrennung im Ottomotor" in 1967 [1.1]' Naturally, the field of mixture formation and combustion in the spark-ignition engine has wit nessed great technological advances and many new findings in the intervening years, so that the time seemed ripe for presenting a summary of recent research and developments. There fore, I gladly took up the suggestion of the editors of this series of books, Professor Dr. H. List and Professor Dr. A. Pischinger, to write a book summarizing the present state of the art. A center of activity of the Institute of Internal-Combustion Engines and Automotive Engineering at the Vienna Technical University, which I am heading, is the field of mixture formation -there fore, many new results that have been achieved in this area in collaboration with the respective industry have been included in this volume. The basic principles of combustion are discussed only to that extent which seemect necessary for an understanding of the effects of mixture formation. The focal point of this volume is the mixture formation in spark-ignition engines, covering both the theory and actual design of the mixture formation units and appropriate intake manifolds. Also, the related measurement technology is explained in this work.
