Method for controlling an ignition system of an internal combustion engine and an ignition system
Abstract:
A method for controlling an ignition system of an internal combustion engine, with which a device for the detection of misfires is provided, comprises operation of the internal combustion engine in a calibration mode, wherein the calibration mode includes stepwise reduction of the ignition energy by changing the ignition parameter starting from an initial value, detecting the reaching of a combustion failure limit based on the signal of the detection device and again reducing the ignition energy if the combustion failure limit has not yet been reached, and storing the ignition parameter at the point in time of reaching the combustion failure limit. When not in the calibration mode, operation of the ignition system takes place according to the stored ignition parameter. With such feedback control, electrode burn of the spark plugs is reduced, leading to an extension of the service life of the spark plugs.
