摘要： An engine control system and method of reducing knocking combustion in a spark-ignited internal combustion engine having exhaust gas recirculation by controlling engine timing based on detection of a misfire in an engine cylinder. The engine control system determines a number of combustion cycles indicative of an amount of time that will pass before misfire gas from the detected misfire will be recirculated to a combustion chamber of any cylinder of the internal combustion engine, and the engine control unit reduces or prevents knocking combustion by adjusting the ignition timing of at least one subsequent combustion cycle after the determined number of combustion cycles have occurred since the misfire was detected.

摘要： An engine includes one or more cylinders configured to receive gaseous fuel for use in combustion. Two gaseous fuel injectors per cylinder, include: a first injector directed at the corresponding cylinder and having an injection capacity of a first amount of gaseous fuel per injection, and a second injector directed at the corresponding cylinder and having an injection capacity of a second amount of gaseous fuel per injection, the second amount being greater than the first amount. The engine is operable in a first mode in which a per-cylinder fuel demand is at or below the first amount, and only the first injector is operable for each cylinder. The engine is operable in a second mode in which the per-cylinder fuel demand is greater than the first amount, and only the second injector is operable for each cylinder.
