Abstract

One third of heat energy generated by the automotive internal combustion engine is wasted in the exhaust system. In the total heat energy supplied to the engine in the form of combustible fuel, approximately 35% to 40% is converted into productive mechanical work and the remaining energy in the form of heat is expelled as the exhaust gas resulting in the rise of entropy and serious environmental pollution. There is a demand to utilize this waste heat from the vehicle into useful work output and thus the wasted heat can be used to run the absorption refrigeration system. The engine exhaust system is connected to the generator of the refrigeration system to supply the input heat required for the refrigeration process. Generator temperature plays a very important role in determining the performance of a vapour absorption system. In a vapour absorption system the source of energy input is heat. In this work, the heat source is taken from exhaust pipe of a 4 stroke engine. Based on this heat supplied the effect on performance of the system has been found with variation in generator temperature for a month and graph has been plotted. Based on the values obtained, suggestions and output of the work is demonstrated.
