Abstract

To increase the life, fuel economy and efficiency of an automobile engine, the researches are being done on the use of different materials. Material selection for an engine depends on various factors. The life of the engine with the material which is capable of giving higher efficiency and fuel economy can be determined with the help of thermal analysis. This paper deals with the thermal analysis of a SI engine block using two different materials; Al alloy 6061 and a metal matrix composite (Al alloy+ 20 % SiC). The engine block was modeled using Pro-E and the thermal analysis was done using ANSYS. The thermal stress, thermal flux and thermal gradient of two different materials have been analyzed. It has been found that the Metal Matrix composite (MMC) has less thermal stress and thermal gradient compared to Al alloy.
