摘要：
This paper aims to study the improvement of the fuel economy of a heavy semi-trailer tractor. Firstly, an optimization is conducted on rearview mirror with a wind tunnel test result of a 0.012 reduction in drag factor. Then the parameters of transmission system are optimized and the control strategy of electronically controlled silicone oil fan is improved, resulting in a reduction in the power consumption of engine accessories, the results of Simulink/ Crusie joint-simulation and chassis dynamometer test show a 1.7% and 2% reduction in fuel consumption of C-WTVC cycle respectively. Finally, a real vehicle road test is carried out with a result indicating that the comprehensive fuel consumption of the optimized vehicle lowers by 1.14 L/100 km, corresponding to a reduction of 3%. © 2022, Society of Automotive Engineers of China.
