Analysis & Comparative Study on Different Cooling Systems of Motorbike Engines and Implementation of Thermoelectric Generator (TEG) on the Exhaust System

Abstract

For a smooth running of the engine as well as to maintain an optimum performance, the engine needs to be cooled down. With the number of motorbikes increasing day by day in Bangladesh, finding an optimum cooling system for the motorbike engine is essential. Three different cooling systems are mostly used in the motorbikes engine of Bangladesh. With air cooling system being used broadly, oil cooling and liquid cooling are also applied. Comparing all the important features of the three cooling systems and their environmental impacts will help finding the most feasible cooling system for the motorbikes of Bangladesh. On the other hand, around 30 to 35% of energy of an IC engine is used to run the vehicles and the rest is wasted as heat. This results in entropy rise and serious environmental pollution. In our study, a waste heat recovery system using a thermoelectric generator (TEG) designed for an I.C. engine is proposed & implemented. Specifically the system converts the waste heat from the exhaust manifold into electrical energy using a TEG. Our experimental data analysis & the result show that this setup can recover a considerable amount of heat
