汽车发动机与起动机性能匹配的计算机测试系统

开发的汽车发动机与起动机性能匹配的测试系统,能在起动的数秒钟内测出发动机的转速和扭矩值,通过对检测数据的高精度曲线拟合,能准确地反映发动机的起动过程,并能保存数据、打印结果、绘制匹配特性曲线以及实现曲线的局部放大显示。系统的可靠性措施保证了系统的持续运转和测试精度。

Testing system of engine and starter matching capability based on computer

The paper introduces a kind of testing system for capability matching between engine and starter based on computer.This system can measure automatically values of the rotational speed and torque within several seconds after starting starter.The process of starting motor is showed through the datafitted.The testing data can be saved,the results and curve can be printed and the curve can be enlarged locally.The persistent running and test accuracy of the system are ensured by the re-liability measures.
