Patent number: 7055313Abstract: A method for controlling reductant added to an exhaust of an engine having a lean NOx catalyst and a particulate filter adjusts a reductant amount during particulate filter regeneration. The method adjusts the reductant amount to account for reducing agents released from the particulate filter that are experienced by the lean NOx catalyst. In addition, management of particulate filter regeneration is based on both an estimated amount of stored particles and conditions of the lean NOx catalyst. In this way, operation of both the particulate filter and the lean NOx catalyst can be optimized. Also, termination of particulate filter regeneration is determined based on operating conditions.Type: GrantFiled: February 22, 2001Date of Patent: June 6, 2006Assignee: Ford Global Technologies, LLCInventor: John David Russell

Patent number: 7047126Abstract: A method for operating at least an intake and exhaust valve in a cylinder with a piston of an engine in a vehicle, comprising during conditions of an engine shut-down, maintaining at least one of the intake and exhaust valves in a closed position, and during conditions where said at least one valve is in said closed position operating with the other of the intake and exhaust valve open, then closing the other of the intake and exhaust valve, and then opening the other of the intake and exhaust valve to generate braking torque to slow the engine.Type: GrantFiled: March 14, 2005Date of Patent: May 16, 2006Assignee: Ford Global Technologies, LLCInventor: Donald J. Lewis

Patent number: 7000383Abstract: A method and a system for improved reductant delivery to an exhaust gas aftertreatment device for a lean burn internal combustion engine exhaust are presented. The system includes a heated evaporator unit into which a mixture of reductant and air in injected, wherein the mixture is vaporized and introduced into the exhaust gas aftertreatment device. Introducing the reductant mixed with air into the heated evaporator unit prevents lacquering and soot deposits on the heated element housed inside the unit, and also speeds up the vaporization process due to better reductant distribution thus reducing system response delays and improving conversion efficiency of the exhaust gas aftertreatment device. The reductant delivery system is further improved by adding a catalyst to it, and by preventing the reductant and air mixture from coming into direct contact with the surface of the heating element.Type: GrantFiled: November 29, 2004Date of Patent: February 21, 2006Assignee: Ford Global Technologies, LLCInventors: Michiel J. van Nieuwstadt, Devesh Upadhyay, Michael Goebelbecker, William Charles Ruona

Patent number: 6945227Abstract: A method for controlling mode transitions, such as from stratified to homogeneous mode, in a direct injection engine adjusts an intake manifold outlet control device, such as a cam timing, to rapidly control cylinder fresh charge despite manifold dynamics. In addition, a coordinated change between an intake manifold inlet control device, for example a throttle, and the outlet control device is used to achieve the rapid cylinder fresh charge control. In this way, engine torque disturbances during the mode transition are eliminated, even when cylinder air/fuel ratio is changed from one cylinder event to the next.Type: GrantFiled: October 24, 2002Date of Patent: September 20, 2005Assignee: Ford Global Technologies, LLCInventors: John David Russell, Gopichandra Surnilla, Stephen Lee Cooper

Patent number: 6938410Abstract: A system and method for controlling an internal combustion engine having a plurality of cylinders, at least some of which may be selectively deactivated to provide variable displacement operation, including temperature management of at least one engine/vehicle component by monitoring the temperature of the component and controlling activation of at least one cylinder to control the temperature of the component. In one embodiment, the engine/vehicle component is an emission control device, such as a catalytic converter.Type: GrantFiled: May 3, 2004Date of Patent: September 6, 2005Assignee: Ford Global Technologies, LLCInventors: Christopher P. Glugla, John Ottavio Michelini

Patent number: 6935311Abstract: A system is described using a fuel quality sensor for controlling various aspects of engine operation. In particular, an acoustic wave sensor is utilized to measure viscosity and density of gasoline fuels. This measurement is utilized to predict engine combustion quality during an engine start. Based on the prediction, the method adjusts engine operating parameters (such as fuel injection amount and ignition timing) to achieve improved vehicle driveability and engine combustion.Type: GrantFiled: October 9, 2002Date of Patent: August 30, 2005Assignee: Ford Global Technologies, LLCInventors: Jacobus Hendrik Visser, Allan Joseph Kotwicki, Allan J. Lippa, Carina Eva Irene Bjornsson, Carol S. Smith, Daniel Lawrence Meyer, John D. Russell, Michael Howard Parsons, Philip William Husak

Patent number: 6880524Abstract: A method for controlling a diesel engine exhaust gas recirculation system is described. In particular, a simplified diesel engine system is provided where presence of exhaust gas recirculation of flow is controlled via a two-position valve, while a quantity of exhaust gas recirculation is adjusted by varying the throttle valve. In this way, a reduced cost diesel exhaust gas recirculation system is achieved that provides the functionality of having variable amounts of exhaust gas recirculation.Type: GrantFiled: April 15, 2002Date of Patent: April 19, 2005Assignee: Ford Global Technologies, LLCInventors: Freeman Carter Gates, Hossein Bina
