METHOD AND ARRANGEMENT FOR CONTROLLING MISFIRE

摘要

The inventive arrangement comprises a control unit (1) that is arranged to form misfire control commands to cylinder specific regulating units and is connectable to cylinder specific first sensors (3). The control unit is also connectable to second sensors (2) of at least two different types. The arrangement further comprises a map (4) for mapping values of the first sensors and the second sensors. The values of the first sensors indicate misfire conditions cylinder specifically and the values of the second sensors indicate at least two variables of the engine. The map (4) indicates also a misfire area (22) and an operation point (23) of the engine in relation to the variables and the misfire condition.
