The analysis of conventional and non conventional piston mehanism from aspect of mechanical stresses

Abstract

The IC engine represents vital part of every mobile system, as well for the agricultural machines. In difference from cars, where by production, life cycle is determined, agricultural machines presents different kind of mobile systems. From agricultural machines long life is expected, as well as the reliability during the life cycle. The development of IC engines with better performances as the consequence have the greater mechanical stresses, which have negative influence on life cycle of the engine, and with that on the life cycle of the mobile system. In the paper will be shown comparison of piston mechanism forces between conventional and nonconventional type of the piston mechanism, and on this way it will be performed comparison stresses, which occur in one and in other piston mechanism. On the basis of comparison, it will be determined, which piston mechanism is better from the aspect of the reliability.
