| Abstract: | This paper analyzes the performance of cooling and lubrication for powertrain system and the performance of exhaust system to improve the efficiency of cooling and lubrication, eliminate emission pollution and noise and keep the performance of cold start. Measuring the temperature and pressure of internal combustion engine＇s cooling and lubricating systems accurately can improve combustion thermal efficiency, fuel economy and output of power, increasing 2% respectively. Residual-heat can be utilized to defrost and demist, to improve comfort and safety. Thermal energy recovery of exhaust system can reduce electromagnetic radiation, improve environment significantly. |
