A STUDY ON THE EVALUATION PARAMETERS FOR OPTIMAL MATCHING OF AUTOMOBLIE POWERTRAIN

The evaluation method for the matching of automobile powertrain is discussed in the paper. Evaluation parameters are the followings: utilization degree of power performance-loss ratio of driving power, utilization degree of fuel economy-utilization ratio of efficiency and the energy efficiency to compromise vehice performance and fuel economy. The three parameters mentioned above can be taken as the evaluation parmeters for optimal matching of automobile powertrain.
