Abstract

A very complex demand from customer, laws and business requirements will have to be met by future design of internal combustion engines for light duty applications. Customers expect further improvements in durability, reliability, driving performance, fuel economy and ownership costs. Laws requirements focus on substantial reductions in emissions and fuel consumption. In order to maintain or having a better grow business in competitive environment, additional cost reductions in manufacturing will be essential. The focus for future development of gasoline engines will be on improvements in fuel economy combustion systems and reduction losses in part load operation. A combined experimental and analytical approach was followed in this study of stress and temperature on cylinder block under steady-state operation. First, experimental studies were performed to measure temperatures and stresses under stable conditions of operation. In addition, the value of stress at the point can be obtained by placing high temperature strain gauges on the engine block. Subsequently, the detailed stress distributions on the engine block were predicted by a finite element analysis. A comparison of the predicted stress on the analysis of finite elements were being compared with the experiment's stress value.
