    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: A system and method for operating a multiple cylinder internal combustion engine having at least two spark plugs per cylinder include a first control wire coupled to a first spark plug of a first cylinder and a second spark plug of a second cylinder, and a second control wire coupled to a second spark plug of the first cylinder and a first spark plug of the second cylinder with the first and second spark plugs of the first cylinder being selectively fired during the power stroke of the first cylinder and the first and second spark plugs of the second cylinder being selectively fired during the power stroke of the second cylinder to provide individual control of each spark plug using a number of control lines less than the number of spark plugs.
