摘要
本文阐述了无外载惯量加速测功原理,指出了国内现有同类仪器存在的问题。提出了采用油门定开度、多次自由加、减速测量在用汽车发动机动力性与机械损失功率的方法,从而提高测量精度,获得重复性好的测试结果。
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.
