    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： A system and method for operating an engine having ionization signal sensing include detecting plug fouling and controlling the engine using progressively more aggressive control strategies if the fouling condition persists. A first control strategy may be used when the number of engine starts or running time are below corresponding thresholds and a second strategy otherwise. The first strategy may employ progressively more aggressive control procedures to eliminate spark plug deposits that may include repetitive sparking, exhaust cycle sparking, increasing engine loading, advancing spark timing, increasing air/fuel ratio, and increasing idle speed, for example. The second strategy may include similar corrective actions employed in a different order and/or to a lesser degree in an attempt to eliminate plug fouling without any noticeable change in engine operation or performance as perceived by the vehicle operator. The control strategies may be applied to individual cylinders, cylinder banks, or all cylinders.
