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

The dynamic movement of the engine 1 is steered and the presence of non-ignition can be seen from the search for operational non-uniformity caused by mistakes. The force transmitted between the chassis 2 and the engine 1 of the vehicle installed according to the invention is sensed, the magnitude of which is compared to a predetermined threshold value and an external force applied to the engine from above this threshold value. This is predicted and the search for possible incombustibility 8 is hindered when this external force is applied to the engine and the load of the engine is lower than the predetermined load value. It is also used for the protection of catalytic converters.
