Abstract
This invention relates to a method applied in combustion engines having two spark plugs in each combustion chamber for controlling ignition and ionization current measurements, one of the spark plugs acting as a sensor for the ionization current measurements. The ignition voltage supplied to each of the spark plugs in a chamber is controlled such that the spark duration of the spark plug acting as the sensor is less than 50% of the other spark plug in the chamber.
