| Abstract: | Having described the principle of power measuring with inertia, acceleration, this paper puts forward a new method of measuring the power performance and mechanieal losses of the gasoline engine on board by multiple accelerations and decelerations at a given throttle position with no external load. The method has higher precision and better repeatability of testing compared with existing instrument. |
