Publication number: 20070261661Abstract: An engine cover for a vehicle includes a frame extending generally about the perimeter of the cover and adapted for mounting to an engine of the vehicle, and a skin extending across and secured to the frame. In one embodiment, the frame is made of a moulded plastic material and the skin is a stamped metal, such as aluminum. In another embodiment, the skin comprises multiple sections each secured to the frame so that one or more sections may be modified to alter the appearance of the cover and/or location of service items, such as an oil fill cap or dip stick for different applications while minimizing the number of components that need modification. A method for covering an engine according to the present invention includes securing at least one engine cover skin to an engine cover frame and securing the frame to an engine.Type: ApplicationFiled: May 10, 2006Publication date: November 15, 2007Applicant: Ford Global Technologies, LLCInventor: Jimmey Fogolini

Patent number: 7295417Abstract: Systems and methods for valve actuation use series-connected coils of upper and lower electromagnets acting as electromagnetic generators that attempt to maintain a constant magnetic flux, while their forces are essentially independent. A valve controller initiates valve actuation by reducing holding force of the holding electromagnet. As spring force begins to move an armature away from the holding electromagnet, the associated coil generates a voltage that attempts to maintain constant flux. This generated voltage causes a large increase in current that essentially transfers the flux to the other on-coming coil, which attracts and holds the armature against its associated spring force to open or close the valve. The internal voltage generated inside the two coils operates even if the coils are supplied with zero external voltage (shorted) to transfer stored energy directly between the coils. Energy may be transferred indirectly using an energy storage device.Type: GrantFiled: May 4, 2004Date of Patent: November 13, 2007Assignee: Ford Global Technologies, LLCInventor: Allan J. Kotwicki

Patent number: 7294092Abstract: A method for controlling a coasting downshift in an automatic transmission having a torque converter that includes an impeller driveably connected to an engine and a turbine hydrokinetically coupled to the impeller and driveably connected to the transmission input. During a coast condition, the speed of the turbine decreases, and the speed of the engine decreases to and is maintained at an engine idle speed. After the downshift event begins, the turbine speed increases due a transfer of torque from an off-going transmission control element to an oncoming control element. Engine speed increases steadily until it reaches the target engine speed. The downshift is completed, and engine speed decreases until it again reaches the idle speed.Type: GrantFiled: October 11, 2005Date of Patent: November 13, 2007Assignee: Ford Global Technologies, LLCInventors: Ralph Walker, Jesse Brunais, Karl Jungbluth, Todd Newman

Patent number: 7295915Abstract: An internal combustion engine includes an advanced vehicle system controller (VSC) that calculates a total power demand to meet a driver wheel power demand plus any accessory loads and independently schedules an engine speed and load operating point to meet the total power demand. A reduction in available engine brake power that is not associated with a driver input, and would ordinarily cause the VSC to respond by raising engine speed, is detected. The driver wheel power demand is reduced to compensate for the reduction in available engine brake power such that the VSC does not need to raise engine speed to meet the driver wheel power demand. A magnitude of the reduction may be determined according to a calibration map to allow a trade off to be made between driveability and noise, vibration, and harshness.Type: GrantFiled: May 1, 2006Date of Patent: November 13, 2007Assignee: Ford Global Technologies, LLCInventors: Shunsuke Okubo, Fazal Syed

Patent number: 7293406Abstract: A method for rapidly heating an emission control device in an engine exhaust uses excess air added to the exhaust via an air introduction device. After an engine cold start, the engine is operated to raise exhaust manifold temperature to a first predetermined value by operating the engine with a lean air-fuel ratio and retarded ignition timing. Once the exhaust manifold reaches the predetermined temperature value, the engine is switched to operate rich and air is added via the air introduction device. The added air and rich exhaust gas burn in the exhaust, thereby generating heat and raising catalyst temperature even more rapidly. The rich operation and excess air are continued until either engine airflow increases beyond a pre-selected value, or the emission control device reaches a desired temperature value. After the emission control device reaches the desired temperature, the engine is operated substantially around stoichiometry.Type: GrantFiled: October 22, 2003Date of Patent: November 13, 2007Assignee: Ford Global Technologies LLCInventors: Donald James Lewis, James Michael Kerns, Matthew John Gerhart, Ralph Wayne Cunningham

Patent number: 7291576Abstract: The present invention provides a regenerable catalyst composition suitable for entrapping SOx. The composition of the invention comprises a copper oxide having the formula (Cu/(A oxide) where A oxide is SiO2, Zr—SiO2, Al2O3, TiO2—Al2O3, ZrO2 and In2O3 or mixtures thereof. Copper loading may vary from about 10 to 60 mol % and is preferably about 25 mol %. The catalyst composition adsorbs SOx as metal sulfate under lean conditions and desorbs accumulated SOx as SO2 under rich conditions. Such reversible SOx trap are able to operate under conventional NOx trap operating conditions to prevent sulfur poisoning of the NOx trap. Furthermore, these traps may be regenerated under rich conditions at 300-450° C.

Patent number: 7292932Abstract: A system and method for controlling the speed of an engine includes determining a desired engine power output and engine speed, and determining whether the desired engine speed is within one of a number of predetermined engine speed ranges. It is then determined whether a noise-vibration level for the vehicle is within a target range when it is determined that the desired engine speed is within one of the predetermined engine speed ranges. The noise-vibration level is a function of at least one of a corresponding vibration level for one or more vehicle mechanical systems, and a noise level for the passenger compartment for the engine operating at the desired engine speed. The engine is then controlled at the desired engine speed when the determined noise-vibration level is within a target range, and it is determined that the desired engine speed is within one of the predetermined engine speed ranges.Type: GrantFiled: November 13, 2006Date of Patent: November 6, 2007Assignee: Ford Global Technologies, LLCInventors: David Ledger, George Dolan, Jason Konopa, Jeffrey Boismier, Floyd Cadwell
