| Abstract: | Power detection equipment of the automobile engine is complex in structure and difficult in operation.Then it is difficult to promote average maintenance shop.Therefore,a portable type of automobile engine power measuring instrument with simple operation,low cost is developed.The engine speed is measured by using the current impulse in the ignition coil,the torque is obtained through measuring braking force of driving wheels,and the power output of automobile engine is calculated.The experiment results indicate that this apparatus can easily inspect the power output of automobile engine benefit by its rational structural design.The errors can satisfy the requirements of measuring accuracy. |
