Abstract
In a method relating to an engine with n cylinders, fuel is injected in a predetermined order into the cylinders in a manner which is synchronized with the position of the pistons of the engine. The method includes the following steps after start-up: injection into m cylinders in a predetermined order of injection; measurement of engine speed and/or acceleration; continuation of injection in a predetermined order of injection if engine speed and/or acceleration exceed(s) a predetermined threshold; continuation of injection with a delay in the event of the contrary. The method can be used with respect to the start-up of a direct injection engine.
