Patent number: 8397695Abstract: 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.Type: GrantFiled: February 16, 2012Date of Patent: March 19, 2013Assignee: Ford Global Technologies, LLCInventors: Chris Paul Glugla, Daniel Lawrence Meyer, Michael John Cullen, Garlan J. Huberts, Michael Damian Czekala, Ben Allen Strayer

Patent number: 8176893Abstract: 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.Type: GrantFiled: August 30, 2008Date of Patent: May 15, 2012Assignee: Ford Global Technologies, LLCInventors: Chris Paul Glugla, Daniel Lawrence Meyer, Phil William Husak, Kelvin Lee Dobbins, Michael Damian Czekala

Patent number: 8060293Abstract: Systems and methods for controlling an internal combustion engine include adjusting fuel delivered to a cylinder during a transient event by an amount indexed by number of combustion events after detecting the transient event. A base fueling parameter may be adjusted by an adaptive correction value indexed by combustion events after the transient event is detected, with the adaptive value determined using air/fuel ratio difference of previous combustion events during similar transient operating conditions associated with the same combustion event index number. Ionization sensor signal characteristics may be used to determine actual air/fuel ratios used to determine the air/fuel ratio difference and corresponding adaptive correction values. The adaptive values may be modified in response to a vehicle refueling event based on an amount of added fuel relative to existing fuel in the vehicle fuel tank.Type: GrantFiled: June 16, 2009Date of Patent: November 15, 2011Assignee: Ford Global Technologies LLCInventors: Daniel Lawrence Meyer, Christopher Paul Glugla, Mrdjan J.
