Book Description,
Valve wear has been a serious problem to engine designers and manufacturers for many years. 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, the phasing out of leaded petrol, reductions in the sulphur content of diesel fuel, and the introduction of alternative fuels such as gas all have implications for valve and seat insert wear. This book aims to provide the reader with a complete understanding of valve recession, starting with a brief introduction to valve operation, design, and operating conditions such as loading and temperature. A detailed overview of work carried out previously, looking at valve and seat wear, is then given and valve and seat failure case studies are discussed.
