Temperature Distribution across the Piston, Liner and Cylinder Head of Conventional and Catalytic Coated 2-Stroke SI Engine Using Finite Element Analysis by ANSYS

ABSTRACT The temperature distribution across the piston, liner and cylinder head of conventional Engine (CE) and Copper Coated Engine (CCE) was determined to study the performance of lubricating oil with the help of finite element method (FEM) using ANSYS software package. For any engine, the use of lubricating oil is a must and it should not be deteriorated, which causes mechanical damage to the engine and decrease in the efficiency. Hence, if the engine is to be tried with any alternative fuel and the engine is to be modified in design, the performance of lubricating oil is to be checked. As it is very difficult to do this experiment practically, FEM helps in this situation. Also, this method (finite element analysis) is used to calculate the wall temperature which is used in combustion calculations. The temperature at the component surfaces was predicted to be increased with CCE over CE. The temperature of lubricating oil was found to be increasing with CCE over CE but it was within the safe temperature limit to avoid deterioration.
