Diagnosis and Elimination Analysis of Ignition System Faults
Microcomputer controlled ignition systems is used for modern fuel vehicles,and the engine ignition performance is relatively stable.However,the internal structure of the ignition coil,factors such as engine over-heating,driver's incorrect driving habits,spark plug maintenance,fuel quality,and computer programs have also brought some problems to the ignition system.The article is based on the control principle of the separate igni-tion system of the Magotan B8.Case 1 illustrates the fault diagnosis and troubleshooting using the fault of the N70 ignition coil;Case 2 takes the SB17 fault as an example to explain the mechanism and causes of its occur-rence,and to eliminate the fault;Case 3 takes the fault of the ignition switch as an example,and diagnoses and eliminates the fault.To diagnose and eliminate faults in the ignition system,it is necessary to consider the causes of the faults from multiple perspectives.
