本文探讨柴油发动机以它运动部件的转动惯量为发动机无外载加速过程的负载,进行快速测功的原理。通过试验分析导出发动机额定功率Nemax与发动机一定转速区间无外载加速时间的函数关系。以此为基础研制成数字式加速测动仪,以满足汽车、拖拉机保修企业快速检测发动机动力性的要求。
This article explores the diesel engine with its moving parts of the inertia of the inertia of the engine without external load of the acceleration process, the principle of rapid measurement. Through the test analysis, the engine power Nemax is derived as a function of the no-load acceleration time in a certain speed range of the engine. Based on this, a digital acceleration tester was developed to meet the requirements of automobile and tractor warranty enterprises to quickly test engine power.
