利用计算机采集发动机信号,实时地计算出发动机的运行参数,控制信号由计算机通过接口电路输出到测功机,并可在计算机中编程进行控制测功机的励磁电流的变化,这样就可以实时地满足发动机各种变工况的运行需要,从而实现车用发动机道路行驶工况的模拟
The engine signal is collected by the computer and the operating parameters of the engine are calculated in real time. The control signal is output by the computer to the dynamometer through the interface circuit, and can be programmed to control the variation of the exciting current of the dynamometer in the computer. In this way, To meet the various operating conditions of the engine running needs, in order to achieve the car engine road driving conditions simulation
