摘要
传统的坐式摩托车发动机台架性能试验方法是测试发动机的曲轴功率。本文介绍了该种发动机台架试验的一种新型设备—ＬＺＤＣ型直流电力测功系统，它是采用输出轴测功的办法，此种方法较之传统的方法更加完善和合理。
The traditional method for the measurement of scooter engine performances with test bench is to measure the power of engine crankshaft.A new kind of equipment LZDC direct-current electrical dynamometer system,which measures the power of output-shaft of engine,is presented here.This system is more complete and reasonable than traditional method.
