METHOD AND DEVICE FOR DETECTING MISFIRES OF THE AIR/FUEL MIXTURE FEEDING AN INTERNAL COMBUSTION ENGINE PROPELLING A MOTOR VEHICLE AND THEIR APPLICATIONS

摘要

we control the dynamic behaviour of the engine (1), and deduced the existence of misfire on the basis of the detection of behavior caused by these problems.there is pressure from the engine (1) to the chassis (2) of the vehicle in which it is installed, the magnitude of these stresses is compared to a predetermined threshold value, and deduces, from the level of this threshold is exceeded, the presence of stress extu00e9rie measures applying to the engine.the detection of potential failures (8) is inhibited when these external forces are applied to the engine (1) when the load is lower than a predetermined load value. application: protection of catalytic converters.
