PROCEDURE AND APPARATUS FOR DETECTING COMBUSTION FAILURES OF AN INTERNAL COMBUSTION ENGINE AND REGULATED IGNITION.

摘要

ACCORDING TO THE INVENTION, THE GAS PAR (CG) IS DETERMINED FOR EACH COMBUSTION IN EACH CYLINDER, THE ENGINE REGIME (N) AND THE PCA PRESSURE ARE MEASURED) IN THE AIR INTAKE MANIFOLD DURING THE CORRESPONDING INTAKE PHASE, CALCULATED BY INTERPOLATION IN A CARTOGRAPHY A REFERENCE PAIR (CREF) IN FUNCTION OF NY PCA, SHALL BE MADE, FOR EXAMPLE, C REF BY PRODUCT WITH A COEFFICIENT (K) ASSOCIATED WITH THE CORRESPONDING CYLINDER AND / OR THE STABILIZED OR TRANSITORY OPERATION MODE, FOR DEDUCT AN INTENDED THEORETICAL TORQUE (CPR) TO BE COMPARED WITH THE PAR GAS (CG) TO CONSIDER THAT THERE IS A COMBUSTION FAILURE IF CG / CPR S2 AND IF CPR-CG AT THE THRESHOLD THRESHOLD OF NOXY COMPONENT EMISSION THRESHOLD IN THE EXHAUST GASES.
