Patent number: 6869456Abstract: A method for starting a fast light-off catalytic reformer for producing hydrogen-rich reformate fuel from hydrocarbon fuel and air, the reformer having means for receiving flows of fuel and air, a reforming catalyst for reforming the fuel and air mixture, and an ignition device. A control system selects fuel and air flow rates to form a lean fuel/air mixture and operates the ignition device to ignite the lean mixture to produce hot exhaust gases that flow over and heat the reforming catalyst for a first length of time. Fuel flow is then stopped temporarily for a second length of time, and further ignition is terminated. Fuel flow is then restarted and adjusted to provide a rich fuel/air mixture which is directed to the heated catalyst for reforming into reformate fuel. Air flow may also be adjusted in setting the lean and/or rich fuel/air mixtures.Type: GrantFiled: August 28, 2002Date of Patent: March 22, 2005Assignee: Delphi Technologies, Inc.Inventors: Michael R.

Patent number: 6866063Abstract: A low leak pressure control actuator for, e.g., controlling pressure in an automatic transmission system, includes a poppet and a check ball slidably disposed within a housing. The poppet and check ball are movable between a de-energized configuration, plural partially energized configurations, and a fully energized configuration. In the de-energized configuration, the poppet and check ball prohibit all flow to and from the supply port and permit flow between the control port and the exhaust port. In the partially energized configurations, the poppet and check ball permit flow to and from all of the ports, and incremental changes in the internal displacement of the poppet produce incremental changes in a control pressure. In the fully energized configuration flow, the poppet and check ball prohibit all flow to the exhaust port and permit fluid flow between the supply port and the control port.Type: GrantFiled: September 6, 2002Date of Patent: March 15, 2005Assignee: Delphi Technologies, Inc.Inventor: Miguel I.

Patent number: 6866020Abstract: A vacuum management system for an engine with variable valve lift includes a vacuum control valve at the entrance to the intake manifold to increase vacuum within the manifold as needed and preferably only when it can be done without impairing fuel economy or engine performance. Vacuum may then be used for any of various vacuum-assisted devices and functions, for example, boosting a vehicle braking system. The numerical relationships among important operating parameters are determined in a laboratory, and a programmable engine control module (ECM} is provided with algorithms and tables of such values by which the ECM is able to vary valve lift and vacuum control valve position to provide optimum flow across the intake valves and optimum manifold vacuum under all engine operating conditions.Type: GrantFiled: June 12, 2002Date of Patent: March 15, 2005Assignee: Delphi Technologies, Inc.Inventors: Brian K.

Patent number: 6867603Abstract: Soot content in Diesel engine lubrication oil is determined using electrical resistance measurements of the oil at high frequency. A sensor in the form of a capacitor is immersed in the oil, wherein the oil serves as a dielectric between the plates. The capacitance and resistance between the plates change as a function of engine oil condition. An inductor is placed in series with the sensor, and high frequencies are sweeped over a range to find resonance where the capacitive and inductive reactances cancel. At this frequency, the resistance of the oil is measured and the condition of the oil thereby determined.Type: GrantFiled: December 4, 2002Date of Patent: March 15, 2005Assignee: Delphi Technologies, Inc.Inventors: Warren Baxter Nicholson, Yingjie Lin, Larry M. Oberdier, Joseph Pierre Heremans

Publication number: 20050050970Abstract: A cap assembly (10) is used during the assembly of a sensor (22) that is to be mounted to a support (30). The support (30) will eventually be mounted to a structure (16) that will hold a fluid therein. Epoxy (56) holds the sensor (22) to the support (30). The cap assembly (46) includes a body (48) having a predetermined length and a shape matching the shape of the support (30). This allows the body (48) to be removably securable to the support (30). The cap assembly (46) also includes an end plate (50) covering the body (48) to prevent epoxy (56) from flowing passed the cap assembly (46). The cap assembly (46) also includes a handle (52) for removing the cap assembly (46) from the support (30) when the epoxy (56) has cured.Type: ApplicationFiled: September 8, 2003Publication date: March 10, 2005Applicant: DELPHI TECHNOLOGIES, INC.Inventors: Samuel Palfenier, Manuel Quintana, Clemente Marquez

Patent number: 6863048Abstract: A vacuum system for an engine with variable valve lift includes a controllable vacuum-forming valve at the entrance to the intake manifold and a programmable engine control module (ECM) to increase vacuum as desired within the manifold by modulating the valve as needed to optimize fuel economy. To provide vacuum brake assist, a brake booster diaphragm is connected conventionally to the manifold and a vacuum storage tank and check valve are disposed between the booster diaphragm and the manifold. During periods of vehicle deceleration, when engine load is low, the ECM may switch the VVL-controlled intake valves to a higher lift to increase the pumping capacity of the engine, while simultaneously partially closing the vacuum-forming valve to create vacuum in the intake manifold, the brake booster, and the vacuum storage tank at little or no expense to engine performance.Type: GrantFiled: June 12, 2002Date of Patent: March 8, 2005Assignee: Delphi Technologies, Inc.Inventors: James F. Burkhard, Brian K. Allston, John S. Lylak, Jr.
