Patent ID: 8397692

Claim:
A method of synchronizing injection with engine phase in an engine with electronic injector control having n cylinders into which fuel is injected directly into each of the cylinders successively in a predetermined sequence, the fuel injection being synchronized with a position of a piston in the corresponding cylinder, the method comprising the following steps, performed when the engine is started: injecting fuel into m cylinders in the predetermined injection sequence when the corresponding pistons, put into motion by means of a starter, are at an end of a compression phase, m being determined in advance as a function of n, measuring engine speed and/or acceleration, continuing the injection in the predetermined sequence if the engine speed and/or acceleration exceed a predetermined threshold, the injection being synchronized with the engine phase in this case, and continuing the injection with a phase change with respect to the preceding injections and with respect to the predetermined sequence, this phase change being a function of n and m, so that the injection is synchronized with the engine phase, in the contrary case, wherein the method does not employ a camshaft sensor.
