Patent number: 8997698Abstract: A system for a multi-cylinder compression ignition engine includes a plurality of nozzles, at least one nozzle per cylinder, with each nozzle configured to spray oil onto the bottom side of a piston of the engine to cool that piston. Independent control of the oil spray from the nozzles is provided on a cylinder-by-cylinder basis. A combustion parameter is determined for combustion in each cylinder of the engine, and control of the oil spray onto the piston in that cylinder is based on the value of the combustion parameter for combustion in that cylinder. A method for influencing combustion in a multi-cylinder engine, including determining a combustion parameter for combustion taking place in in a cylinder of the engine and controlling an oil spray targeted onto the bottom of a piston disposed in that cylinder is also presented.Type: GrantFiled: December 4, 2013Date of Patent: April 7, 2015Assignee: Delphi Technologies, Inc.Inventors: Gregory T. Roth, Harry L Husted, Mark C. Sellnau

Publication number: 20130261927Abstract: A method of authenticating an automotive device connected to an engine control system that stores an authentication code in memory of the automotive device that is generated by an encryption algorithm using an identification code of the automotive device as a seed value. The engine controller determines a verification code using a complementary encryption algorithm that also uses the identification code received from the automotive device as a seed value. The engine controller compares the authentication code to the verification code, and indicates that the automotive device is not authentic if the authentication code does not correspond to the verification code. Advantageously, authenticating the automotive device will be done autonomously by the engine controller without prompting by a technician using special equipment such as a laptop computer.Type: ApplicationFiled: March 28, 2012Publication date: October 3, 2013Applicant: DELPHI TECHNOLOGIES, INC.Inventors: Clinton W. Erickson, Karl A. Schten, Harry L. Husted

Patent number: 7606655Abstract: An engine data acquisition and control system measures cylinder pressure at a high degree of resolution and then processes it for portions of the combustion cycle of interest for performing combustion calculations. The data are utilized to calculate combustion parameters, and the combustion parameters may be utilized to control the engine's fuel and/or spark timing/duration, and other variables affecting the combustion process. The system architecture provides for acquisition of very large amounts of data without unduly loading the CPU.Type: GrantFiled: August 27, 2007Date of Patent: October 20, 2009Assignee: Delphi Technologies, Inc.Inventors: Harry L. Husted, Clinton W. Erickson, Ashish D Punater, Karl A. Schten, Gerald A Kilgour, Michael P. Conyers

Patent number: 7475671Abstract: A method for compensating fuel injection timing when a torque signal or throttle command indicates that a transient operation is about to transpire. The control adjusts the fuel injection timing in advance of the transient operation to prevent loss of torque due to change in combustion phase position. During engine operation in pre-mix mode of combustion, rapid changes in fueling quantity can affect the combustion angle as well as the temperature in the combustion chamber, causing late or early combustion phasing. The present invention anticipates a change in combustion phasing by sensing a change in demanded fueling rate. The Engine Control Module (ECM) then applies a nest of algorithms to advance fuel injection timing during acceleration or to shorten ignition delay for deceleration by retarding fuel injection timing. As the engine returns to steady state operation, the compensation in injection timing is progressively reduced to zero.Type: GrantFiled: December 21, 2007Date of Patent: January 13, 2009Assignee: Delphi Technologies, Inc.Inventors: Gerald T. Fattic, Harry L. Husted

Patent number: 7323264Abstract: A fuel cell system in accordance with the invention includes a single, central electronic controller (CPU) for controlling at least the Air Handling sub-system, the Reformer sub-system, the Power Electronics sub-system, and the Customer Interface sub-system. The central controller provides a central location for easier serviceability; increases data transport efficiency by eliminating lengthy links between distributed controllers; eliminates the need for multiple mechanical enclosures; allows for controller thermo conditioning in one mechanical enclosure; and reduces parasitic power losses by employing a single power supply.Type: GrantFiled: May 27, 2004Date of Patent: January 29, 2008Assignee: Delphi Technologies, Inc.Inventors: John G.

Patent number: 7216481Abstract: An improved method and apparatus for providing reformate into an engine exhaust stream including aftertreatment devices such as a particulate trap and an NOx filter regenerable by hydrogen-rich reformate injected into the engine exhaust ahead of the aftertreatment devices. A pump pressurizes a hydrocarbon catalytic reformer, and a three-way valve for dividing the reformate injected into the engine exhaust. The reformer draws oxygen from the engine exhaust rather than ambient air as in the prior art. Thus, the only pressure drop that the pump/reformer system must overcome is within the reformate supply system between the reformer take-off point and the reformate entry points. In a configuration wherein the exhaust is taken off ahead of the inline particulate trap, a separate particulate filter is preferably incorporated into the reformer supply line.Type: GrantFiled: September 23, 2005Date of Patent: May 15, 2007Assignee: Delphi Technologies, Inc.Inventors: John A. MacBain, Harry L. Husted

Patent number: 7005830Abstract: A charging strategy for a rechargeable battery pack is disclosed. The battery pack is used in an application that includes a dynamoelectric machine that may operate as a motor, drawing power from the battery pack, or as a generator, delivering regenerative energy to the battery pack. The strategy monitors the nature, intensity, duration and frequency, among other things, associated with encountered episodes of regenerative energy from the dynamoelectric machine, and adjusts subsequent recharging processes to allow a calculated amount of headroom to accommodate regenerative energy inputs in the future, which may be assumed to be equal in nature, intensity, duration and frequency to what has already been observed. Overcharging is reduced or eliminated, while maximizing the amount of charge on the battery pack, and thus duration of use.Type: GrantFiled: May 21, 2003Date of Patent: February 28, 2006Assignee: Enerdel, Inc.Inventors: Stephen W. Moore, Harry L. Husted
