Abstract:
The present invention is an operation control method on the basis of an ion current in an internal combustion engine, the method comprising a step of detecting the ion current generated within a combustion chamber 30 so as to control an operating state of the internal combustion engine 100 on the basis of a state of the detected ion current, wherein a control at an engine start point in time on the basis of the state of the ion current is stopped for predetermined cycles just after the engine start.
