Abstract
In an engine the signal wheel sensor is quite important for achieving engine timing, enhancing the performances and reducing emission. This study designed a simulation teaching platform, in which the engine was replaced by a motor so as to realize the signal wheel sensor's operation according to the practical operating condition; additionally, an engine analyzer was employed for the acquisition of output signals. The experimental results reveal that the motor's rotational speed was regulated within the range of 0–3640 rpm, and the signal output waveform of the sensor accords with the sensor's signal output rules during the engine's operation. Further, this platform shows strong demonstration and structural display functions and can help the engineering technicians to master sensor's structure, working principle and signal output characteristics.
