【Abstract】 A computer programm for simulating the fuel economy and power performance of the motor vechicles and the approach to improving its accuracy are described in this paper. Based on the computation and optimization by this programm accompanied with the vehicle tests on the road, the pewertrain system for the CA141 truck has been rematched rationally. As a result,the power performance and fuel economy of this truck have been improved b 3.9% and 5.4% respectively.更多还原
