Engine failures result from a complex set of conditions, effects, and situations. To understand why engines fail and remedy those failures, one must understand how engine components are designed and manufactured, how they function, and how they interact with other engine components. To this end, this book examines how engine components are designed and how they function, along with their physical and technical properties. Translated from a popular German reference work, this English edition sheds light on determining engine failure and remedies. The authors present a selection of engine failures, investigate and evaluate why they failed, and provide guidance on how to prevent such failures. A large range of possible engine failures is presented in a comprehensive, readily understandable manner, free of manufacturer bias. The scope of engines covered includes general-purpose engines found in heavy commercial vehicles, railway locomotives and vehicles, electrical generators, prime movers, and marine engines. Such engines are technical precursors to automotive engines. This book is for all who deal with engine failures: those who work in repair shops, shipyards, engineering consultancies, insurance companies and technical oversight organizations, as well as R&D departments at engine and component manufacturers. Researchers, academics, and students will learn how even the theoretically impossible can-and will-happen.

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.

Tribological Processes in Valvetrain Systems with Lightweight Valves: New Research and Modelling provides readers with the latest methodologies to reduce friction and wear in valvetrain systems—a severe problem for designers and manufacturers. The solution is achieved by identifying the tribological processes and phenomena in the friction nodes of lightweight valves made of titanium alloys and ceramics, both cam and camless driven. The book provides a set of structured information on the current tribological problems in modern internal combustion engines—from an introduction to the valvetrain operation to the processes that produce wear in the components of the valvetrain. A valuable resource for teachers and students of mechanical or automotive engineering, as well as automotive manufacturers, automotive designers, and tuning engineers. Shows the tribological problems occurring in the guide-light valve-seat insert Combines numerical and experimental solutions of wear and friction processes in valvetrain systems Discusses various types of cam and camless drives the valves used in valve trains of internal combustion engines—both SI and CI Examines the materials used, protective layers and geometric parameters of lightweight valves, as well as mating guides and seat inserts

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.

General Motors Powertrain manufactures and designs engines for General Motors vehicles. The Tonawanda engine plant facility produces 4, 5, 6, and 8 cylinder engines for Mercury Cruiser, GMC, Chevy, Hummer, Buick, and Cadillac. The facility consists of a cylinder head, engine block, and crank shaft machine floors. Along with the machine floors, the facility performs cylinder head, block, and engine assemblies for all of the above engine types. Part tracking and automated process control is a key to General Motors achieving "The World's Best Powertrain". The biggest quality issue for General Motors cylinder head machining is pressing seats and guides into a cylinder head no matter what engine type. Currently, there is no traceability through the seat and guide machines along with data analysis because depth and force data is not retained for an appropriate amount of time. The only test that would be able to detect this type of defect at the engine assembly line would be engine assembly cold test. Testing an engine at a low RPM with natural gas is defined as a cold test. The failure modes for cylinder heads with high seats or guides are for NVH meaning noise. Internal quality metrics have shown that all GM engine plant manufacturing process only has a 5% ability to detect this defect once it happens in its process. There has been many engine pulls at the vehicle assembly plant due to high seats or guides which results in an engine miss fire. Once the engine(s) leave the engine facility, the vehicle assembly plant may catch the defect at DVT (Dynamic Vehicle Test). If the defect is not found at DVT then the defect would be passed onto the customer, where it would then result in a walk home and potential lost customer.
