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.

摘要: Methods and systems are provided for addressing cylinder pre-ignition by adjusting a spray angle of fuel injected into a cylinder responsive to an indication of pre-ignition. A spray pattern of fuel injected in the cylinder is varied based on a cylinder pre-ignition count to reduce cylinder wall impingement of injected fuel while improving air-fuel mixing in the cylinder.

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 and systems are provided for addressing cylinder-to-cylinder imbalances in the incidence of pre-ignition and/or knock. Engine cylinders are fueled based on each cylinder's pre-ignition count to balance the incidence of pre-ignition in each cylinder. The fueling is adjusted to maintain engine exhaust at stoichiometry.

摘要: Methods and systems are provided for identifying and indicating degradation of an engine cylinder spark plug. In response to a cylinder misfire event during selected engine operating conditions, followed by an occurrence of a threshold number and/or rate of pre-ignition events in the same cylinder, a controller may determine that the spark plug is degraded. The controller may limit combustion in the cylinder in response to the degradation. Additionally, cylinder pre-ignition mitigating steps may be taken.

摘要: Methods and systems are provided for identifying and differentiating knock and pre-ignition using a plurality of knock sensors distributed along an engine block. By dynamically adjusting cylinder-specific assignment of the knock sensors for knock detection and pre-ignition detection based on operating conditions of each cylinder, knock and pre-ignition is more reliably identified and distinguished.
