PCT No. PCT/FR96/00725 Sec. 371 Date Dec. 31, 1997 Sec. 102(e) Date Dec. 31, 1997 PCT Filed May 13, 1996 PCT Pub. No. WO96/36803 PCT Pub. Date Nov. 21, 1996Method for identifying cylinder phase in an engine with an ignition and/or injection system wherein each cylinder is individually controlled, and with a sensor cooperating with a rotary target having an indexing element indicating a reference cylinder upper dead center position. The method including the steps of generating, on the reference cylinder, a disturbance other than the interruption of the injection, the disturbance of a type capable of causing a change in the engine torque, detecting the engine torque change by a change in a signal representative of the gas torque, caused by the generation of the disturbance, establishing a relationship between the time of generation and the detection of its result on the engine torque so as to derive the reference cylinder phase at the time of generation of the disturbance, and thereafter the phase of the other cylinders. The method of the present invention being particularly useful for four stroke engines with sequential ignition and/or injection.
