For more precise analysis of vehicle fuel consumption during experimental driving mode, the measurement of energy loss(pumping friction, mechanical friction, alternator friction and etc.) is performed by pre-experiment. On diesel vehicle, mechanical friction is increased according to engine speed and load increasing. Thus the measurement of mechanical friction on diesel engine usually has performed by engine rig test using a dynamometer. However, for diesel vehicle which is going to be performed driving mode experiment, engine dynamometer test spends much time and effort, because it needs a separate operation from vehicle. In this paper, for more convenient way, chassis dynamometer test is attempted for measuring of mechanical friction for diesel engine on vehicle condition and verified with results of engine dynamometer test and NEDC mode test. Via the chassis dynamometer test, less time and effort can be spent than engine dynamometer.
