一、电子测功仪简介用电子测功仪测试发动机的有效功率,是以整机的转动惯量和全机各种阻力作为负载,发动机从怠转状态下,全油门急剧加速至最高空转,而后立即收回油门,便可测出额定转速时的角加速度。用已测出的角加速度乘以转动惯量及其它转换常数,经过运算便可求得其有效扭矩和有效功率。 First, the introduction of electronic dynamometer Electronic dynamometer test the effective power of the engine, the machine is based on the moment of inertia and the whole variety of resistance as a load, the engine from idle state, the full throttle sharply accelerated to the highest idle, then Immediately retrieve the throttle, you can measure the angular acceleration of the rated speed. Multiplied by the measured angular acceleration multiplied by the moment of inertia and other conversion constants, the effective torque and effective power can be calculated.
