Comparative Studies of Heat Flow Rate in the Catalytically Activated Two Stroke SI Engine Components over Base Engine by FEA

Knowledge on heat flow rate across the piston, liner and cylinder head of an engine is highly essential for a designer for arriving at a reasonable configuration of the piston, liner and cylinder head without sacrificing the strength. Heat flow rate across the piston, liner and cylinder head of CE (Conventional Engine, referred as Base Engine) and CCE (Copper Coated Engine, referred as Catalytic Coated Engine/Catalytically Activated Engine) was determined to study the performance of lubricating oil. The prediction of percentage increase of heat flow with the help of finite element analysis (FEA) using ANSYS software package is important, in these components, which determines the efficient combustion by means of catalytic coating on the surface of piston crown and over the inside surface of cylinder head. These studies are conducted on CE and also on CCE in order to emphasize the advantage of CCE over CE in producing efficient combustion. The heat flux rate was found to be increasing along both axis and radius of piston, liner and cylinder head of CCE over CE.
