Patent number: 10544749Abstract: A method for controlling an internal combustion engine having a plurality of cylinders including a first cylinder and one or more remaining cylinders includes selecting a desired auto-ignition dwell for a first combustion cycle for the first cylinder of the plurality of cylinders. A first fuel mass is provided to the first cylinder which is combusted during the first combustion cycle. An actual auto-ignition dwell for the first combustion cycle which results from the first fuel mass is determined and a dwell error is calculated. The dwell error is used to determine a second fuel mass which provided to the first cylinder and which is combusted during the second combustion cycle.Type: GrantFiled: October 11, 2018Date of Patent: January 28, 2020Assignee: DELPHI TECHNOLOGIES IP LIMITEDInventor: Andrew Fedewa

Patent number: 10233850Abstract: A system for controlling the combustion behavior of an engine is provided. The engine is equipped with a plurality of control subsystems that influence combustion in the engine. The system includes a controller configured to receive a plurality of inputs, to determine a desired subsystem states to operate the engine, and to determine a target value for each of a plurality of control parameters, wherein the target values for one or more control parameters depends on the values of the plurality of inputs. The controller is further configured to communicate the target values of control parameters to the control subsystems.Type: GrantFiled: October 14, 2015Date of Patent: March 19, 2019Assignee: DELPHI TECHNOLOGIES IP LIMITEDInventors: Gregory T. Roth, Gary C. Fulks, Andrew Fedewa, Xiaojian Yang, Donald V. Johnson

Patent number: 9863306Abstract: A system is disclosed comprising an engine having coolant passages defined therethrough, a first coolant pump, and a first radiator. The system additionally comprises a second coolant pump, a second radiator, and a liquid-to-air heat exchanger configured to condition the temperature of intake air to the engine. The system further includes a coolant valve means. For a first configuration of the coolant valve means the first coolant pump is configured to urge coolant through the coolant passages in the engine and through the first radiator, and the second coolant pump is configured to urge coolant through the liquid-to-air heat exchanger and through the second radiator. For a second configuration of the coolant valve means the second coolant pump is configured to urge coolant through the coolant passages in the engine and through the liquid-to-air heat exchanger. A method for controlling the system is also disclosed.Type: GrantFiled: January 26, 2015Date of Patent: January 9, 2018Assignee: DELPHI TECHNOLOGIES, INC.Inventor: Andrew Fedewa

Patent number: 8467923Abstract: A vehicle control system for controlling a vehicle deceleration rate that includes a dynamo (e.g. generator/motor) coupled to the vehicle to provide a dynamo deceleration force to the vehicle corresponding to an electric load, an internal combustion engine coupled the vehicle to provide an engine deceleration force to the vehicle corresponding to a throttle position, and a controller coupled to the internal combustion engine and the dynamo. The controller is configured determine a deceleration fuel cutoff (DFCO) request based on an accelerator pedal position, and when a DFCO request is determined increase the throttle position to decrease the engine deceleration force, and increase the electric load on the dynamo to increase the dynamo deceleration force, to control the vehicle deceleration rate.Type: GrantFiled: November 19, 2010Date of Patent: June 18, 2013Assignee: Delphi Technologies, Inc.Inventor: Andrew Fedewa
