Tribological Analysis and Design of a Modern Automobile Cam and Follower by Guangrui Zhu,Chris M Taylor Pdf

An Engineering Research Series title. This excellent and long awaited book is based upon extensive research carried out by the Institute of Tribology at the University of Leeds in the UK and the Ford Motor Company Ltd. It is concerned with both the theoretical and experimental study of the tribological performance of an automobile valve train, having an offset taper cam and a domed follower, incorporated with an hydraulic lash adjuster, with particular reference to the ZETA engine valve train. A sophisticated theoretical model has been developed that predicts the tribological performance of the valve train, and also provides a useful tool for the consideration of the tribological design of valve trains. Additionally the model can estimate the instantaneous and average rotational frequency of the follower, and the performance of the hydraulic lash adjuster. In order to validate the theoretical model, the experimental measurements have been correlated with the theoretical predictions that simulate the test conditions of the valve train. The agreement between the measurements and the predictions show that the model is very reliable. This gives readers great confidence in using the model when dealing with novel and alternative designs of the valve train. COMPLETE CONTENTS: Part One – Theoretical Formulation. Kinematics and dynamics of the cam and follower Hydraulic lash adjuster The maximum hertzian stresses Asperity interactions The oil film thickness Friction and power loss of the valve train The rotation of the follower The overall solution procedure and input/output data An example of the tribological analysis of a valve train. Part Two – Experimental Study. Test apparatus and the instrumentation Calibration of the instrumentation and commissioning tests Test procedure Data processing Experimental results and discussions Part Three – Correlation of theory and experiments. Experimental evidences Theoretical predictions Comparison of results and discussions Overall conclusions.

Engine Tribology by C.M. Taylor Pdf

Customer expectations and international competition are obliging car and commercial vehicle manufacturers to produce more efficient and cleaner products in shorter product cycle times. The consideration of Engine Tribology has a leading role to play in helping to achieve these goals. Specific areas of interdisciplinary interest include: design influences on fuel economy and emissions; new materials (ceramics, steels, coatings, lubricants, additives); low viscosity lubricants; and low heat rejection (adiabatic) engines. This volume gives a detailed and current review on some basic features of tribology particularly associated with internal combustion engines such as: lubrication analysis relevant to plain bearings, Hertzian contact theory and elastohydrodynamic lubrication associated with cams and followers and friction and wear in a general context. Several chapters examine engine bearings, valve trains, (cams and followers) and piston assemblies. For each machine element a background introduction is followed by design interpretations and a consideration of future developments. The important topic of materials, solids and lubricants is focused upon in the concluding chapters. The work will be of interest to engineers and researchers in the automobile, automotive products, petroleum and associated industries.

Design Techniques for Engine Manifolds by D. E. Winterbone,Dr. Richard J. Pearson Pdf

Reports on the significant developments over the past two decades in designing manifolds for internal combustion engines, and shows how mature the calculation of one-dimensional, unsteady flow has become. Particularly describes how many of the limitations of the Method of Characteristics, used to calculate the unsteady flow of the compressible gases in the engine, can be removed by applying finite volume techniques, resulting in more accurate simulations and allowing more rapid and robust calculation. Helps practicing and student engineers understand how wave action in the inlet and exhaust manifolds of reciprocating engines affects the performance of the engine. Distributed in the US by ASME.
