Engine signal wheel sensor is important of engine timing, improve engine performance and reduce emissions. The teaching uses the motor to replace the engine running, so as to realize the signal wheel sensor in accordance with the actual working conditions. The results show that the simulation system signal output of the sensor output signal in accordance with the engine work by using the engine diagnostic instrument. And the system has strong demonstration of functional and structural function, it is helpful for engineering and technical personnel to master the sensor structure, working principle and output signal.
