Patent number: 7607638Abstract: During normal operation of diesel engines the EGR valve poppet often becomes stuck to the valve seat in the closed position, due to excessive build up of exhaust gas debris, which renders the valve inoperable. This usually occurs after the engine is shut down and the valve is seated. Features, which locate the valve poppet in an unseated position when not in use, are implemented into the EGR valve design to prevent this sticking from occurring, thereby increasing product robustness and prolonging product life.Type: GrantFiled: March 8, 2006Date of Patent: October 27, 2009Assignee: BorgWarner Inc.Inventors: Joseph A. Wilson, Michael J. Halsig, John W. Duddles, Hal E. Pringle

Patent number: 7594494Abstract: An electronic throttle control system is described. The system includes a non-contacting sensor stator integrated into an electronic throttle body and is aligned to the sensor rotor attached to the shaft to properly set sensor air gap by assembly aids or by close fit to the throttle body. A motor and vehicle connector is electrically connected to the sensor stator but is allowed to be positioned separately from the sensor stator by means of a flexible interconnect.Type: GrantFiled: January 19, 2007Date of Patent: September 29, 2009Assignee: BorgWarner Inc.Inventors: Robert D. Keefover, Michael J. Halsig, Hal E. Pringle

Publication number: 20080173279Abstract: A method of pressure balancing across a bearing adjacent to a pressure differential is described. The method primarily includes providing a bypass port around the bearing for allowing a fluid flow from a first pressure side to a second pressure side. A throttle body for an engine is also described. The throttle body primarily includes: (1) a bearing cooperating with the valve body; and (2) a bypass port around the bearing for allowing the fluid flow from a first pressure side to a second pressure side.Type: ApplicationFiled: January 3, 2008Publication date: July 24, 2008Applicant: BorgWarner Inc.Inventors: Hal E.

Patent number: 7191754Abstract: A control system having a housing with a bore formed within the housing. A valve member is associated with the bore for controlling the passage of a fluid medium through the bore. An induction sensor is aligned with the valve and facilitates determining the valve position. An inductor is connected to an end of the valve member that is in close proximity to the induction sensor. It is contemplated that this control system can be used in a number of different applications including throttle control systems, turbo actuators, canister purge systems and shift control mechanisms. However, it is within the scope of this invention to incorporate the control system on virtually any type of vehicle system where it is possible to determine the position of a valve utilizing induction sensor technology.Type: GrantFiled: January 5, 2005Date of Patent: March 20, 2007Assignee: BorgWarner Inc.Inventors: Robert D.

Patent number: 6260528Abstract: A three plenum air distribution manifold for intake air to internal combustion engine with long, narrow runners leading from first and second spaced side plenums for delivery of air and recirculating exhaust gases into corresponding combustion chambers of the engine. One end of the spaced side plenums are connected by an acoustically balanced cross over passage selectively closed by a manifold tuning valve for improving engine output torque during low engine speed. A third plenum is positioned intermediate the two side plenums to communicate with the combustion chambers in bypass relation to the side plenums thereby directly supplying air to the combustion chambers through short runners which are selectively opened by valves to optimize engine torque over a higher range of engine speeds. The manifold tuning valve and short runner valves are controlled by an onboard electronic controller responsive to signals from the engine corresponding to parameters such as engine speed.Type: GrantFiled: August 9, 1999Date of Patent: July 17, 2001Assignee: Borg Warner Inc.Inventors: Hal E.
