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.

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-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 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： Various systems and methods are described for controlling engine operation of an engine having a plurality of cylinders, each cylinder including a first and second injector for delivering fuel to the cylinder. One example method comprises operating a first cylinder to combust fuel delivered from both the first and second fuel injector of the first cylinder, and operating a second cylinder to combust fuel delivered from only one of the first and second fuel injectors of the second cylinder. One example system comprises both a port injector and a direct injector coupled to both of a first and second cylinder of the engine with a first fuel reservoir coupled to the port injectors and a second fuel reservoir coupled to the direct injectors. The system further includes a controller configured to vary delivery of the fuels from the injectors to the cylinders during differing operating modes.
