Abstract (en)

[origin: WO2004036018A1] The invention concerns a method comprising a phase which consists in detecting combustion misfiring on the engine paired cylinders, and a downgraded mode whereby, upon detection (20) of a failed cylinder while its paired cylinder is not failed and in the absence of an external control information the engine phasing, the injection phasing is controlled (24) so as to determine which of the two cylinders is actually defective.
