Patent number: 11725598Abstract: A method for controlling engine braking in a vehicle comprises: determining a position of a throttle operator; determining a speed of the vehicle; and determining an engine braking mode selected. In response to the position of the throttle operator being a fully released position and the selected braking mode being a first engine braking mode: controlling an engine and a position of a throttle valve according to the first engine braking mode for applying a first level of engine braking. In response to the position of the throttle operator being the fully released position and the selected braking mode being the second engine braking mode: controlling the engine and the position of the throttle valve according to the second engine braking mode based at least on the speed of the vehicle for applying a second level of engine braking.

Patent number: 11523532Abstract: An electronic device casing includes a body, a movable apparatus, and a handle structure. The body comprises a first stopping surface and a second stopping surface disposed opposite to each other. The movable apparatus is adapted to be detachably assembled in the body. The handle structure is pivotally disposed to the movable apparatus. The handle structure comprises a first arm corresponding to the first stopping surface and a second arm corresponding to the second stopping surface. The movable apparatus is adapted to move between a removed position and an assembled position by rotating the handle structure between an upper pulled position and a lower pressed position.Type: GrantFiled: November 6, 2020Date of Patent: December 6, 2022Assignee: PEGATRON CORPORATIONInventor: Yu-Wen Liu

Patent number: 10968879Abstract: Methods and systems are provided for an exhaust catalyst heating strategy that uses spark retard to increase an amount of heat output by an engine without a combustion stability limit. In one example, a method may include, during an engine cold start, applying an ignition spark at a timing that produces substantially zero combustion torque while maintaining an engine speed greater than a threshold speed via electric motor torque. Furthermore, an amount of heat output by the engine may be controlled by adjusting an airflow through the engine, such as by adjusting one or more of a throttle position and the engine speed.Type: GrantFiled: February 1, 2018Date of Patent: April 6, 2021Assignee: Ford Global Technologies, LLCInventors: Ross Dykstra Pursifull, Joseph Ulrey

Patent number: 10603982Abstract: A vehicular climate control system may include a coolant subsystem configured to circulate coolant between an engine, a thermal generator, and a cabin heat exchanger, and a controller. The controller may be configured to, responsive to an air inlet temperature of the heat exchanger exceeding a threshold, retard engine spark timing to increase heat generation. The threshold may be defined by a quotient of (i) a difference between a discharge temperature target and the air inlet temperature and (ii) a thermal effectiveness parameter that is based on an air flow rate and a coolant flow rate.Type: GrantFiled: October 19, 2017Date of Patent: March 31, 2020Assignee: Ford Global Technologies, LLCInventors: Franco Ragazzi, James George Gebbie, Donald Peter Schneider, III, Alan Douglas Wallington, William Stewart Johnston

Patent number: 10202933Abstract: A combined oil filter and restrictor assembly is disclosed having an oil flow restrictor interposed between first and second filters so that, irrespective of the direction of oil flow through the restrictor, debris cannot enter a small diameter bore 32 in a body of the restrictor thereby reducing the likelihood of restrictor blockage. The combined oil filter and restrictor assembly includes a metal threaded member that enables the combined oil filter and restrictor assembly to be easily and quickly assembled to or removed from a component such as a cylinder head of a variable displacement engine. The combined oil filter and restrictor assembly can be used to provide a restricted flow of oil from oil supply passages to signal oil passages used for controlling the operation of deactivatable hydraulic lash adjusters so as to purge the signal oil passages when the deactivatable hydraulic lash adjusters are not deactivated.Type: GrantFiled: June 21, 2016Date of Patent: February 12, 2019Assignee: Ford Global Technologies, LLCInventors: Prasad Shrikant Khadilkar, James Martin Oates, Matt Haigh

Patent number: 9945344Abstract: Methods and systems are provided for addressing spark plug soot fouling. In one example, spark plug tip temperatures are raised and maintained elevated by advancing spark timing and increasing engine speed, while reducing an amount of EGR being delivered to the engine. The spark plug fouling mitigating actions are adjusted based on whether the engine is in a green condition at an assembly plant or not.Type: GrantFiled: July 31, 2015Date of Patent: April 17, 2018Assignee: Ford Global Technologies, LLCInventors: Chris Paul Glugla, Nelson William Morrow

Patent number: 9732871Abstract: A valve assembly is disclosed, and includes an evacuator and a relief valve. The evacuator includes a suction port that selectively applies a vacuum. The relief valve has an open position and a closed position, and includes an inlet, an outlet, a piston that translates within a chamber, and a pressurized chamber. The piston includes a first end and a second end. The pressurized chamber is fluidly connected to the suction port of the evacuator, and is defined in part by the first end of the piston. The piston translates within the pressurized chamber towards the open position if vacuum is applied to the pressurized chamber.Type: GrantFiled: July 15, 2015Date of Patent: August 15, 2017Assignee: DAYCO IP HOLDINGS, LLCInventors: David E. Fletcher, Brian M. Graichen, James H. Miller, Keith Hampton, Matthew C. Gilmer

Patent number: 9151264Abstract: An ignition timing controlling apparatus for an engine includes an ignition timing map in which high-torque timings are stored, an ECU for changing a high-torque timing obtained from the ignition timing map into a fuel-conserving ignition timing, and an advance angle target amount map in which advance angle target amounts with which the high-torque timing is to be changed into the fuel-conserving ignition timing are stored. The ECU is operable to calculate an advance angle target amount for each of cylinders of the engine based on the advance angle target amount map when a running state of a vehicle is in a cruize state in which little acceleration or deceleration is included, and also to execute advance angle control of changing the ignition timing of each of the cylinders stepwise with respect to the advance angle target amount for each of the cylinders.Type: GrantFiled: September 13, 2012Date of Patent: October 6, 2015Assignee: Honda Motor Co., Ltd.Inventors: Masanori Nakamura, Takeru Abe
