摘要: A system and method for operating an engine having at least two spark plugs per cylinder include controlling at least one actuator to alter combustion within a selected cylinder such that the combustion burn rate determined by ion sense current signals associated with the at least two spark plugs of the selected cylinder approaches a desired combustion burn rate. A desired combustion burn rate is determined based on current engine/vehicle operating and ambient conditions with ion sense signals from each spark plug analyzed to determine combustion timing relative to corresponding ignition timing. Ignition timing and/or other actuators are controlled in response to provide a desired combustion burn rate.

摘要: Methods and systems are provided for reducing late burn induced cylinder pre-ignition events. Forced entry of residuals from a late burning cylinder into a neighboring cylinder may be detected based on engine block vibrations sensed in a window during an open exhaust valve of the late burning cylinder. In response to the entry of residuals, a pre-ignition mitigating action, such as fuel enrichment or deactivation, is performed in the neighboring cylinder.

摘要: Methods and systems are provided for addressing pre-ignition that may be induced in response to actions taken to mitigate a cylinder misfire. An amount of engine load limiting applied may be adjusted to reduce the likelihood pre-ignition while also addressing component over-temperature issues. By limiting an engine load while shutting off fuel in a misfiring cylinder, and while combusting a lean air-fuel mixture in the remaining cylinders, pre-ignition induced by the misfire-mitigating lean combustion conditions can be reduced.

摘要: Methods and systems are provided for addressing cylinder pre-ignition. Each cylinder of an engine may be operated in either a split injection mode or a single injection mode based on the pre-ignition history of the cylinder. The timing and number of injections in the split injection mode is adjusted based on the pre-ignition count of the cylinder.

摘要: Methods are provided for controlling an engine in response to a pre-ignition event. A pre-ignition threshold and a pre-ignition mitigating action are adjusted based on a rate of change of cylinder aircharge. As a result, pre-ignition events occurring during transient engine operating conditions are detected and addressed different from pre-ignition events occurring during steady-state engine operating conditions.

摘要: Methods and systems are provided for mitigating engine pre-ignition based on a feed-forward likelihood of pre-ignition and feedback from a pre-ignition event. In response to an indication of pre-ignition, a cylinder may be enriched while an engine load is limited. The enrichment may be followed by an enleanment to restore exhaust catalyst feed-gas oxygen levels. The mitigating steps may be adjusted based on engine operating conditions, a pre-ignition count, as well as the nature of the pre-ignition.
