Patent number: 7234393Abstract: An improved nutcracker and shelling process use centrifugal force to accelerate nuts so that their shells shatter upon impacting a target surface. The nutcracker includes an impeller having an intake for receiving nuts and an outlet for discharging the nuts.

Patent number: 7234435Abstract: A method for controlling at least an electrically actuated valve to operate in at least a cylinder of an internal combustion engine, the method comprising deactivating an electrically actuated valve in response to an operating condition of a vehicle electrical system, said electrically actuated valve deactivated in a desired position.Type: GrantFiled: September 6, 2005Date of Patent: June 26, 2007Assignee: Ford Global Technologies, LLCInventors: Donald J. Lewis, John O. Michelini

Patent number: 7234436Abstract: A method is disclosed for controlling operation of an engine coupled to an exhaust treatment catalyst. Under predetermined conditions, the method operates an engine with a first group of cylinders combusting a lean air/fuel mixture and a second group of cylinders pumping air only (i.e., without fuel injection). In addition, the engine control method also provides the following features in combination with the above-described split air/lean mode: idle speed control, sensor diagnostics, air/fuel ratio control, adaptive learning, fuel vapor purging, catalyst temperature estimation, default operation, and exhaust gas and emission control device temperature control. In addition, the engine control method also changes to combusting in all cylinders under preselected operating conditions such as fuel vapor purging, manifold vacuum control, and purging of stored oxidants in an emission control device.Type: GrantFiled: February 6, 2006Date of Patent: June 26, 2007Assignee: Ford Global Technologies, LLCInventors: Gopichandra Surnilla, John Ottavio Michelini, John M.

Patent number: 7234437Abstract: A direct-injection internal combustion engine and a combustion method therefore in which fuel injection timing of a fuel injection valve is so configured that (a) the fuel inverted from a cavity in a crown portion of a piston reaches proximity to the discharge electrode portion of a spark plug later than the time of ignition or (b) fuel injection by the fuel injection valve is completed at approximately the same time of ignition. There is no risk of rich combustion at the discharge electrode portion due to the mixed fuel-air mass having a high fuel density, and consequently problems such as wear on the spark plug or smoke generation can be avoided.Type: GrantFiled: March 17, 2006Date of Patent: June 26, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Koji Hiraya, Toshiya Kono, Masahiro Fukuzumi

Patent number: 7234438Abstract: A method of operating an internal combustion engine having a combustion chamber with a piston is disclosed. The method comprising during a first mode, adjusting an operating condition of the engine so that a first mixture of air and fuel in the combustion chamber attains an autoignition temperature and therefore combusts without performing a spark from the spark plug; and during a second mode, adjusting said operating condition of the engine so that a second mixture of air and fuel in the combustion chamber approaches, but does not achieve, said autoignition temperature; and performing a spark from the spark plug after top dead center of piston position so that said second mixture combusts.Type: GrantFiled: September 21, 2005Date of Patent: June 26, 2007Assignee: Ford Global Technologies, LLCInventor: Jialin Yang

Patent number: 7234439Abstract: A control device executes an overlap injection operation, in which one of the plurality of injectors is energized first to inject fuel, and a next one of the plurality of injectors is energized to inject fuel after starting of the energization of the one of the plurality of injectors while the one of the plurality of injectors is still kept energized. The control device corrects an energization period of the next one of the injectors by lengthening the energization period of the next one of the injectors in comparison to a normal energization period of the next one of the injectors, which is set for a non-overlap injection operation of the next one of the plurality of injectors.Type: GrantFiled: April 12, 2005Date of Patent: June 26, 2007Assignee: Denso CorporationInventors: Takashi Kikutani, Hiroyuki Nishimura

Patent number: 7234440Abstract: A system, comprising of an engine having a cylinder therein, a fuel injector coupled to said cylinder and configured to directly inject fuel into said cylinder, a fuel system coupled to said injector, and a controller configured to control engine starting operation, wherein during a start, said fuel injector performs a first fuel injection at least partially during an exhaust stroke of said cylinder, where fuel from said first fuel injection is mixed with air inducted at least during an intake stroke following said exhaust stroke, said fuel injector performing a second fuel injection after said first fuel injection, and combusting fuel from said first and second fuel injections to perform a combustion event in said cylinder.Type: GrantFiled: September 29, 2005Date of Patent: June 26, 2007Assignee: Ford Global Technologies, LLCInventor: James Hilditch

Patent number: 7234441Abstract: A spark plug system includes a center spark plug and a plurality of peripheral spark plugs, the spark plugs extending into a ridge-roof type combustion chamber of an internal combustion engine from the inner surface of a cylinder head and being disposed approximately on the ridgeline of the ridge-roof. The amount by which the center plug projects into the combustion chamber from the inner surface of the cylinder head is different from the amount by which each of the peripheral plugs projects into the combustion chamber from the inner surface of the cylinder head, whereby the time in which the flame propagation of the center plug reaches the flame propagation of the peripheral plugs is delayed.Type: GrantFiled: March 13, 2006Date of Patent: June 26, 2007Assignee: Nissan Motor Co., Ltd.Inventors: Hiroshi Isaji, Shunichi Mitsuishi, Kouichi Mori

Patent number: 7234442Abstract: An internal combustion engine may be provided with independently controllable valves, fuel injectors and ignition elements that may be used to start the engine without a separate auxiliary device such as an electric starter motor. The engine may fire the cylinders under a startup mode of control at the same time it fires the cylinders under a normal mode of control in order to smooth the transition from start up to normal operating mode. Additionally, an internal combustion engine may use independently controllable valves to stop the engine and ensure that one or more of the pistons come to rest at a position which allows them to be used to restart the engine.Type: GrantFiled: June 1, 2006Date of Patent: June 26, 2007Assignee: Bose CorporationInventors: David E. Hanson, Jun Ma, Benjamin G. K. Peterson

Patent number: 7234443Abstract: A valve body or a throttle valve is disclosed that is capable of changing the amount of intake air into an engine according to a gradient angle of a valve body rotatably supported in an intake air passage. The valve body includes at least one first end surface and at least one second end surface formed on an outer circumferential surface thereof. Air eddies occurring from air flow contact with the first and second end surfaces are shifted to each other.Type: GrantFiled: July 13, 2005Date of Patent: June 26, 2007Assignee: Nissan Motor Co.
