Abstract
Recently, it is possible for small sized and high speed diesel engines by development of commonrail system. And in order to increase the engine performance, the cylinder firing pressure is a tendency which increases. On the other side, the weight of engine becomes lightly in spit of high performance diesel engine. Therefore, the weight optimization for engine components is very important point on the design process. Also, the weight optimization must necessarily be considered the robust design against a fatigue failure. This paper focuses on the weight optimization of crankshaft according to web shape at the light duty diesel engine, and torsion characteristics of crankshaft is considered with 1D and 3D analysis tools.
