Patent number: 6725821Abstract: An apparatus and method for starting an engine having a starter generator for providing a rotational force to a pulley in order to provide the necessary torque to start an engine. The starter generator also receives a rotational force to the pulley wherein the starter generator generates a current when the pulley receives the rotational force. A valve deactivation system reduces the compression in a cylinder of the engine, thereby reducing the torque required to perform a starting sequence of the engine, either permitting this apparatus to be applied to larger engines, lower ambient temperatures, or some combination thereof.Type: GrantFiled: January 15, 2002Date of Patent: April 27, 2004Assignee: Delphi Technologies, Inc.Inventors: William S. Warren, Jean Joseph Botti, James Patrick Waters

Patent number: 6655325Abstract: The present system and method relate to power generation utilizing an exhaust side solid oxide fuel cell. Fuel is burned in an engine in the presence of air. The engine exhaust passes through a solid oxide fuel cell where it is consumed in the production of electricity and ionization of oxygen in an air stream also introduced to the solid oxide fuel cell. The solid oxide fuel cell effluent fuel stream and/or air stream can be recycled through the engine, directed through a turbine to recover additional energy therefrom, and/or passed through a catalytic converter. The resulting system exhaust has negligible to zero amounts of nitric oxides, hydrocarbons, carbon monoxide, and particulates.Type: GrantFiled: February 1, 1999Date of Patent: December 2, 2003Assignee: Delphi Technologies, Inc.Inventors: Jean Joseph Botti, Malcom James Grieve, Carl Elmer Miller

Patent number: 6485852Abstract: A compact integrated thermal management and fuel reformation system and method includes a thermally insulated wall forming an envelope having an interior chamber housing, a solid oxide fuel cell stack and a mixed mode heat exchanger. A recuperator having interior walls that are color graded to provide temperature zones effecting a positive temperature gradient in the direction of the solid oxide fuel cell stack is disposed within the chamber and close coupled to the fuel cell stack for absorbing radiation therefrom. The recuperator further heats the partially preheated oxidant gas and partially or fully reforms incoming fuel gas. Manifolds having oxidant and fuel channels for conducting reformed fuel and heated oxidant from the recuperator to fuel cell oxidant and fuel inlets are arranged to maximize fuel flow at the portions of each fuel cell adjacent the recuperator and to maximize oxidant flow near central portions of each fuel cell. A method for providing a tailored anode fuel stream is also provided.Type: GrantFiled: January 7, 2000Date of Patent: November 26, 2002Assignee: Delphi Technologies, Inc.Inventors: Carl Elmer Miller, Bruno Depreter, Haskell Simpkins, Jean Joseph Botti

Patent number: 6230494Abstract: The power generation system and method of the present invention employ a solid oxide fuel cell which reforms fuel to a degree which is controlled by the amount of fuel introduced to the solid oxide fuel cell. The effluent is directed preferably through a heat exchanger and then into an engine. This hybrid system more efficiently produces energy, both mechanical and electrical, over conventional systems.Type: GrantFiled: February 1, 1999Date of Patent: May 15, 2001Assignee: Delphi Technologies, Inc.Inventors: Jean Joseph Botti, Malcolm James Grieve, Carl Elmer Miller
