DETERMINATION AND CORRECTION OF THE ANGULAR POSITION PHASING OF A FOUR-TIME INTERNAL COMBUSTION ENGINE WITH INDIRECT INJECTION AND WITH SEQUENTIAL INJECTION CUT / SEQUENTIAL REINJECTION CONTROLLED IN TIME

摘要

Method for determining the phasing of the angular position of a four-stroke internal combustion engine with indirect injection and sequential injection / sequential reinjection controlled over time, characterized in that it comprises, the engine being in operation, the following steps: observation of the curve (3, 4) of the engine speed (1) as a function of time (2) during a phase of sequential injection and / or sequential reinjection performed in accordance with the expected oscillations of the transmission ,. discrimination according to the shape of said curve (3, 4), a substantially linear shape (3) being indicative of a correct phasing, while a substantially sinusoidal shape (4) is indicative of incorrect phasing.Application to the correction phasing.
