Analysis of Energy Storage from Exhaust of an Internal Combustion Engine

Mohit Kumar

Abstract


The current highlighted problems are related to scarcity of energy, and the exhaust waste heat by the internal combustion engines which cause environmental pollution. The total heat supplied to the engine in the form of fuel is partially converted into useful mechanical work; rest will be ejected to the environment as exhaust gases which cause serious environmental pollution. Exhaust gas formed due to the combustion of fuels such as natural gas, gasoline/petrol, diesel, fuel oil or coal, which then discharged into the atmosphere through an exhaust pipe. The exhaust gas from an internal combustion engine carries away the heat of combustion in abundant form. The energy available in the exit stream of many energy conversion devices goes as waste, if not used properly. The main objective of the proposed project is to utilize heat from the exhaust gases of a diesel engine and convert heat to useful work. In the present work, a shell and finned tube heat exchanger integrated with an Internal Combustion engine setup to extract heat from the exhaust gas and a thermal energy storage tank used to store the excess energy available is investigated in detail. Energy supplied to an engine is the heat value of the fuel consumed. But only a part of this energy is transferred into useful work. From heat balance sheet of a typical IC engine, I found that the total heat loss is around 35–45%, of which 33% is due to exhaust gases and the rest is lost to the surroundings
