Abstract:
In conventional motorcars, about 40 percent of fuel consumption has become useful energy and about 60% is driven out of the engine by the cooling system and the exhaust. Therefore, there is an opportunity to recover energy from this waste energy. The system which is used to recover this waste energy is called the waste energy recovery system. Putting a supplementary cycle at the end of the Otto cycle, or in other words on the exhaust outlet gases, could be a suitable way to recover. In this research, Stirling cycle was used to recover the waste heat of the internal combustion engine exhaust gases. Initially, a one-dimensional ignition simulation was designed to predict the exhaust gas conditions from the internal combustion engine. To validate the results from this simulation, the experimental results of the EF7-NA engine have been used. These results indicate that the exhaust gas temperature range varies from 393 to 848 ° C. So, by installing the Stirling engine heater, this waste energy can be turned into useful work. To validate the results of a one-dimensional Stirling engine simulation, the Solo V161 Stirling engine has been used in this research. After results validation, the proposed model of the Sterling engine, which has a working pressure of 50 bar, has been used. The results of the combination Stirling cycle in full bar conditions indicate that the output power for pressure condition of 50 bar Stirling Engine increases by an average of 15%.
