DESIGN AND STRESS ANALYSIS OF NODULAR CAST IRON MONOBLOC PISTONS FOR FOUR STROKE DIESEL ENGINES
The nodular cast iron monobloc piston is presented. Undoubtedly, it will be of interest for future engine developments. The design principles in comparison to the composite piston are discussed. A three-dimensional finite element calculation, which covers the entire piston, is shown on the example of a 185-mm-dia piston. The deformations and stresses due to firing pressure and temperature are presented. A fatigue life assessment shows that this type of piston is reliable even after a large amount of operating hours at high loads in supercharged engines.
