Application of Research Waveform Analysis in Automotive Electronic Control Engine Fault Diagnosis

Through the vehicle for digital oscilloscope,working conditions of automobile electronic control system can be observed,the signal waveforms that sensor and actuator of electronically controlled engine happens can truly reflect the dynamics of the whole process while also appears to be a change in laws,these laws will be summed up by a waveform analysis,the fault position of engine can be found quickly,or even the cause of malfunction may be found and removed in time.
