Abstract

This paper introduces the principle of the engine waste heat recovery system. The organic Rankine cycle (ore) system is proposed to improve the efficiency of waste heat recovery. GT-power software is used to make a DI engine model of 493ZLQ3. The model simulates the exhaust temperature on the brake power curve and brake torque curve based on the optimized results, and put a comparison with the test. The results show that the error range of the simulation results is 5% compared with the test results. Therefore, the results of the simulation and analysis can afford valuable reference for calculating the entire power system. The whole power system can obtain the output net work of 2.67kW.
