8. Just before the piston has reached Top Dead Centre, a spark from the electrode of the spark plug injector ignites the air/petrol mixture, and the next expansion stroke begins. The exact instant of ignition is determined by the prevailing operating conditions. Depending on when the ignition instant occurs, the spark is fired either to the fixed electrode across a gap of 3.5mm or to the electrode in the piston. The spark follows the laws of physics and is fired to the piston as soon as the piston electrode is closer than 3.5mm to the centre electrode. As a general rule, the spark is fired to the fixed electrode at low load and to the piston electrode at high load.
