Title: Ignition timing control method for internal combustion engine by ion current
Inventor: ASANO MORIHITO
IPC: F02P5/153
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To solve such a problem that the occurrence of a knock can not be detected and sometimes accurate control of an ignition timing can not be carried out when an ion current is abnormally increased resultant from the influence of environment. SOLUTION: In an ignition timing control method for an internal combustion engine by an ion current wherein an ion current generated in the combustion chamber 10 of an internal combustion engine at each ignition time is detected, through detection of a knock component superimposed on a detecting ion current, the occurrence of a knock is detected, and the ignition timing of the internal combustion engine is regulated when the knock occurs. A reference value based on which the intensity of a generating ion current is decided is set, and the peak value of the generating ion current is detected. When the detecting peak value exceeds a reference value, detection of the occurrence of the knock is prohibited, and when detection of the occurrence of the knock is prohibited, an ignition timing is set.
