用微机研究涡轮增压柴油机无外载测功

Experimental Investigation on Power Measurement of Turbocharged Diesel Engine at No External Load by Microcomputer

探讨了增压柴油机无外载测功原理，利用微机、设计软、硬件系统，测试了6135ZG涡轮增压柴油机。将微机检测的结果与测功器得到的数据相对比，结果比较满意。可为内燃机故障诊断及在无测功设备条件下，确定发动机功率提供了一种简便的方法。

This paper studies the principles of power measultment of turbochargeddiesel engine at no external load. With :he help of miciocomputet, designed hardwareand software systems, an experimental investigation on the power measurement of model6135ZG turbocharged diesel engine is carried out. Satisfactory conclusion is achieved by comparing the result of this new power measuring method with that of the tiaditional one. In the failure diagnosis applications and in the case of no dynamometer,the new method is a simple way to measure tuibochangeu diesel engine power.
