To achieve the goal to meet the worldwide demand for the improvement of fuel efficiency and the reduction of exhaust, the thermal management system of vehicle adopts an adjustable electronic thermostat to vary the valve-open temperature and full-open lift with the operating condition of the vehicle in this study. The control temperature of the engine coolant of the system has been lifted 20℃ than conventional mechanical system so as to improve the fuel efficiency 2% or more. This study describes the procedure of assessment of performance of thermal management system and compares the results of CVS-75 chassis dynamometer tests lor the vehicle ill which mechanical or electronic thermal management system installed.
