Computer-aided design of thermally loaded axi-symmetric diesel engine components

Abstract

Computer-aided design techniques are being increasingly used in the development of diesel engines. The paper describes the use of finite element methods for the design of piston crowns, cylinder liners and exhaust valves and it is shown that a marked correlation exists between predicted and measured results. Hence factors such as piston ring groove distortion, exhaust valve temperatures and liner stresses can be readily evaluated at reasonable cost.
