Automotive Engine Valve Recession


Book Description

An “Engineering Research Series” title. Valve wear and its effect upon engine performance still presents a major challenge to the tribologist. Although new valve materials and production techniques are constantly being developed, these advances have been outpaced by demands for increased engine performance. The drive for reduced oil consumption and exhaust emissions, use of lead-replacement and low-sulphur fuels, and the introduction of alternative fuels such as gas all have implications for valve and seat insert wear. Automotive Engine Valve Recession aims to provide the reader with a complete understanding of valve recession. The fundamental nature of contact and wear between valves and valve seats is considered, followed by an outline of the essential features of valve operation and the potentially serious problems associated with wear and valve recession in automobile engines. An overview is then given of an experimental study of valve wear and the development of special apparatus for the simulation of engine operating conditions carried out in the School of Mechanical Engineering, University of Sheffield, UK. CONTENTS INCLUDE: Introduction Valve operation and design Valve failure Analysis of failed components Valve and seat wear testing apparatus Experimental studies on valve wear Design tools for prediction of valve recession and solving valve failure problems.

Automotive Fuels Reference Book


Book Description

The first two editions of this title, published by SAE International in 1990 and 1995, have been best-selling definitive references for those needing technical information about automotive fuels. This long-awaited new edition has been thoroughly revised and updated, yet retains the original fundamental fuels information that readers find so useful. This book is written for those with an interest in or a need to understand automotive fuels. Because automotive fuels can no longer be developed in isolation from the engines that will convert the fuel into the power necessary to drive our automobiles, knowledge of automotive fuels will also be essential to those working with automotive engines. Small quantities of fuel additives increasingly play an important role in bridging the gap that often exists between fuel that can easily be produced and fuel that is needed by the ever-more sophisticated automotive engine. This book pulls together in a single, extensively referenced volume, the three different but related topics of automotive fuels, fuel additives, and engines, and shows how all three areas work together. It includes a brief history of automotive fuels development, followed by chapters on automotive fuels manufacture from crude oil and other fossil sources. One chapter is dedicated to the manufacture of automotive fuels and fuel blending components from renewable sources. The safe handling, transport, and storage of fuels, from all sources, are covered. New combustion systems to achieve reduced emissions and increased efficiency are discussed, and the way in which the fuels’ physical and chemical characteristics affect these combustion processes and the emissions produced are included. There is also discussion on engine fuel system development and how these different systems affect the corresponding fuel requirements. Because the book is for a global market, fuel system technologies that only exist in the legacy fleet in some markets are included. The way in which fuel requirements are developed and specified is discussed. This covers test methods from simple laboratory bench tests, through engine testing, and long-term test procedures.
