Book Synopsis Automotive Engine Valve Recession by : Roger Lewis
Download or read book Automotive Engine Valve Recession written by Roger Lewis and published by Wiley. This book was released on 2002-01-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Dynamic and Fatigue Assessment of Heavy-Duty Engine Valves by : Angelina Eret
Download or read book Dynamic and Fatigue Assessment of Heavy-Duty Engine Valves written by Angelina Eret and published by Springer Nature. This book was released on 2024-02-02 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides findings on the simulation of the valve dynamic to the current technological standards. Above all, it delivers a simulation based and predictive approach on the fatigue strength assessment of four-stroke heavy-duty engine valves. The demand for more efficient combustion engines with fuel flexibility goes along with increasing component requirements regarding strength and durability, while the development costs should remain low. In this context, the present book focuses on the gas exchange valves of heavy-duty engines. Especially, the valves on the exhaust side have an increased risk of fatigue failure. The aim of this book is the generation of a predictive fatigue strength assessment to strengthen the frontloading of the exhaust valve design process and to increase the reliability of the component. In the context of fatigue assessment, this book examines the loads of the exhaust valve during its working cycle. Beside the high temperature and cylinder pressure, further loads act on the exhaust valve like actuation force or an eccentric impact of the valve on the valve seat ring. Furthermore, a bold valve secondary dynamic in the form of valve bending vibrations is observed on the exhaust valves of heavy-duty engines increasing the valve load even more. The cause of this secondary dynamic is unknown. This book investigates the valve loads to get the necessary input for the fatigue strength assessment. With respect to a predictive approach, the determination of valve dynamic and valve loads is based on a multibody simulation model of the valve train. In order to deliver predictive results and a transferable method, this simulation model includes all relevant physical effects to describe the valve dynamic accurately during all valve load phases of the working cycle. With the simulation model, the root cause for the bold valve secondary dynamic is examined iteratively. The model delivers not only the cause for the valve secondary dynamic but most importantly the critical valve loads. These loads deliver the input for the fatigue strength assessment. To ensure the robustness of the load data determined by the simulation model, the sensitivity of influences on the valve load is examined. In this context geometrical misalignment, fluctuations in load data and variable engine operation points are considered. A load collective based on the variation of influences on the valve load is the result of this analysis. All the results of the influence and sensitivity study are generated with the newly developed simulation model of the valve train. Moreover, this book outlines measurements on a testbed engine. In scope of these measurements are temperature and strain measurements of the valve. The generated data validate the simulation model of the valve train. Additionally, the statistical evaluation of the data is used in the subsequent fatigue strength assessment to increase the reliability of the results.
