【Abstract】 Vehicle power performance may affect transport and security, so it must be detected in definite time. Chassis dynamometers are used by most national detecting station, the means is relatively exact and credible, but the classification of vehicle is often mistaken for no good method. On the basis of the research of testing experiments on power loss of automobile power performance in use, mathematical models of each part of power loss were developed in this paper. The influential factors of measuring automobile power performance were also analyzed. Taking a BJ121 truck as an example, the general appraisement method on test of automobile power performence was set up.更多还原
