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.

Tribology, the science of friction, wear and lubrication, is one of the cornerstones of engineering’s quest for efficiency and conservation of resources. Tribology and dynamics of engine and powertrain: fundamentals, applications and future trends provides an authoritative and comprehensive overview of the disciplines of dynamics and tribology using a multi-physics and multi-scale approach to improve automotive engine and powertrain technology. Part one reviews the fundamental aspects of the physics of motion, particularly the multi-body approach to multi-physics, multi-scale problem solving in tribology. Fundamental issues in tribology are then described in detail,from surface phenomena in thin-film tribology, to impact dynamics, fluid film and elastohydrodynamic lubrication means of measurement and evaluation. These chapters provide an understanding of the theoretical foundation for Part II which includes many aspects of the physics of motion at a multitude of interaction scales from large displacement dynamics to noise and vibration tribology, all of which affect engines and powertrains. Many chapters are contributed by well-established practitioners disseminating their valuable knowledge and expertise on specific engine and powertrain sub-systems. These include overviews of engine and powertrain issues, engine bearings, piston systems, valve trains, transmission and many aspects of drivetrain systems. The final part of the book considers the emerging areas of microengines and gears as well as nano-scale surface engineering. With its distinguished editor and international team of academic and industry contributors, Tribology and dynamics of engine and powertrain is a standard work for automotive engineers and all those researching NVH and tribological issues in engineering.

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.

An Engineering Research Series title. One of the remarkable achievements of modern manufacturing techniques is the ability to achieve nano-metre surface finishes. Ultraprecision machining based on single-point diamond turning (SPDT) is a very important technique in the manufacture of high-precision components where surface finish is critical. Complex optical surfaces, for example, can be produced without the need for post-machining polishing. This book focuses on the aspect of modelling nano-surface generation in ultra precision SPDT. Potential industrial applications in the prediction of surface quality, the process optimization, and precision mould manufacturing are also studies. The essential differences between single-point diamond turning and conventional machining are described. The history and technology of single-point diamond turning are presented and single chapters emphasize the related metrology and cutting mechanics. Important aspects of surface generation are also discussed. Features of the text are the sound approach, systematic mathematical modelling, and computer-aided simulation of surface generation in the development of surfaces exhibiting nano-surface qualities. TOPICS COVERED INCLUDE: Fundamentals of ultra-precision diamond turning technology Cutting mechanics and analysis of microcutting force variation Mechanisms of surface generation Characterization and modelling of nano-surface generation Computer-aided simulation of nano-surface generation Diamond turning of aspheric optics. Based upon the extensive experience of the authors Surface Generation in Ultra-precision Diamond Turning: Modelling and Practices will be of interest to engineers, scientists, and postgraduate students.
