Effect of Preheated Pure Oxygen on IC Engine Performance using Heat Pipe Exhaust Heat Recovery Method

Abstract

Nowadays, the requirements and dependency of people on vehicles are increasing day by day which lead to high emission of flue gases and it results in the severe environment pollution. Many researchers have done research to improve the efficiency of IC engine. The main reason for less efficiency is the incomplete combustion of fuel in the IC engine. To improve the efficiency, we carried out the experiments with two stroke petrol engine by supplying preheated pure oxygen instead of air. The oxygen is preheated by the exhaust heat recovery system using heat pipe. In this research work, engine performance is analyzed in two ways primarily by using the pure oxygen and secondly by using the pre-heated pure oxygen through heat pipe. The output response in this work is brake thermal efficiency without heat pipe (without inlet-air-preheating) and with heat pipe (with inlet air preheating). The output response is calculated with the use of numerical formula. Exhaust gases energy is used to preheat the inlet pure oxygen supplied to petrol engine with the help of heat pipe. A heat pipe without bend is used here in which working fluid is water. Experimental results show that there is an increase in brake thermal efficiency with use of heat pipe.
