A method for switching a combustion engine comprising a number of combustion chambers, an air supply channel connected to said combustion chambers, whose passage can be adjusted by means of a throttle valve, whereby a spark plug, which can be ignited via adjustable ignition timing, is associated with each combustion chamber. The method comprises the switching from a first operating condition, in which the combustion engine is coupled to a first mechanical part and the combustion engine delivers a relatively low maximum engine torque with a maximally open throttle valve, to a second operating condition, in which the combustion engine is coupled to a second mechanical part and in which the combustion engine delivers a relatively high maximum engine torque with a maximally open throttle valve, and vice versa. The ignition timing of the spark plug is adjusted upon switching from the one operating condition to the other until the electronically controllable throttle valve occupies the position associated with said other operating condition and the ignition timing of the spark plug has been adjusted to the timing associated with this position. The engine torque delivered by the combustion engine gradually increases or decreases thereby. |
