ICEF2005-1313 PREDICTION OF HEAT FLOW AND TEMPERATURE FOR PISTONS WITH IMPROVED COOLING METHODS

Abstract

ABSTRACT This study deals with the prediction of the heat flow and temperature of an IC engine piston having different types of cooling methods. This decade has seen a very significant increase in the load rating of the internal combustion engines. There is a marked shift in the current engines from the conventional NA (Naturally Aspirated) engines. The presence of turbo chargers and super chargers has improved the power output by more than two times. The engines develop a pressure upto180 bar and release very high heat energy. This has resulted in a piston crown temperature to the tune of 350 Deg. Centigrade. The increase in temperature will have a very serious effect on th
