摘要
The performance of the exhaust heat recovery system (EHRS) is analysed. First, an integrated vehicle model with the cabin heating system is established. A vehicle test is conducted to verify the simulation model and to assess the performance of the original system. Using the simulation model, the interaction between the EHRS, cooling system, cabin heating system and exhaust system is studied. Then the cooling system is improved aiming to reduce the fuel consumption and improve the system performance. The numerical results show that increasing the pump speed ratio can significantly improve the performance of low-temperature heating, and has little effect on fuel consumption. Adjusting the cooling circuit of the EHRS can effectively reduce fuel consumption and improve heating performance.
