Abstract |
The main aim of this work is to predict the design performance based on stress/strain and behavior of cylinder head under various operating conditions. The effects of various engineering operating conditions such as combustion gas maximum internal pressure, thermal stress behavior and fatigue stress of the cylinder head have been analyzed. In any working engine the piston and the cylinder head are the most vulnerable members due to increased mechanical and thermal loadings. The mechanical loading is mainly due to gas pressure in the gas chamber and its magnitude can be judged in terms of peak pressure. Thermal loading is due to temperature and heat transfer conditions in the piston surface cylinder liner and cylinder head. The geometry modeling was carried out using popular computer-aided engineering tools, CATIA V5R19 and NX8 (Uni-graphics) and the computational work of stress and thermal analysis was done using a finite element analysis (FEA) software package ANSYS. The result can be used to determine the quality of design as well as identify areas which require further improvement, and also the maximum stresses is found not exceeding material strength of cylinder head. In this work we have also designed and compare three types of cylinder heads and formulated the importance of water jacket, oil jacket and fins. By managing cylinder head cooling, it is possible to minimize the weight of cylinder head and the size of cooling system to reduce overall engine weight. Index terms - Cylinder head, Mechanical load, Thermal load, FEA, Water jacket, Oil jacket, Fins. | |||||||||
