本文介绍的测试发动机扭矩、功率的不解体检验仪器,可以象传统的水力、电力测功机一样测出发动机各个转速下的功率和扭矩。它是根据发动机的作功方程,用机内的运算单元对传感器传出的转速进行解算而得出发动机的功率和扭矩值。并可借助记录仪连续作出速度特性曲线,测试时间为1～2秒,还可测出摩擦功,都可达到较高的精度。 This article describes the test engine torque, power does not disintegrate test equipment, can be the same as the traditional hydraulic, electric dynamometer measured the same speed of the engine under various power and torque. It is based on the work of the engine equation of work, with the machine’s computing unit on the sensor output speed calculated engine power and torque values. And with the recorder to make a continuous speed curve, the test time is 1 to 2 seconds, but also measured the friction work, can achieve higher accuracy.
