Abstract:
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.
