METHOD FOR GENERATING A SYNCHRONISATION SIGNAL FOR CONTROLLING THE ELECTRONIC INJECTION SYSTEM OF AN INTERNAL COMBUSTION ENGINE

摘要

A method for generating a synchronisation signal for an internal combustion engine having phased sequential multipoint injection is disclosed. The engine comprises a crankshaft sensor for indicating top dead centre times for each cylinder, and a system for measuring the gas torque generated by each combustion. Said method comprises the steps of modifying injection for a given reference cylinder, determining the resulting alteration of the gas torque for said reference cylinder, comparing the times at which injection was stopped and a torque alteration was detected, and identifying the intake top dead centre times for the reference cylinder.
