Patent number: 6347612Abstract: A control system is adapted for a direct injection engine of spark ignition type provided with an exhaust gas purifying catalyst in an exhaust passage, a fuel injection valve for directly spraying fuel into combustion chambers, a sparking plug having an electrode projecting into the combustion chamber. The control system includes an intake air amount controller for controlling the amount of intake air to be admitted into the combustion chambers, and a fuel injection controller for carrying out stratified combustion in a stratified combustion region set in a low engine load region while carrying out uniform combustion in a uniform combustion region set in a high engine load region.Type: GrantFiled: September 11, 2000Date of Patent: February 19, 2002Assignee: Mazda Motor CorporationInventor: Hirofumi Nishimura

Patent number: 6347613Abstract: An electronic throttle control mechanism having a housing and cover member with a throttle valve, gear mechanism, motor, and failsafe mechanism. The housing, cover member and other components are made of a plastic composite material. A spring member positioned between the housing and sector gear member which is attached to the throttle valve shaft, biases the throttle valve plate member toward the closed position. A spring-biased plunger member biases the throttle plate member from its closed position to a default or “limp-home” position. Several of the components, such as the motor holder, electrical connectors and housing for the throttle position sensor (TPS), are molded together into the cover member to form an integrated modular assembly. This reduces the cost and weight and improves the reliability and overall size of the mechanism.Type: GrantFiled: July 5, 2000Date of Patent: February 19, 2002Assignee: Visteon Global Technologies, Inc.Inventor: James Richard Rauch

Patent number: 6347614Abstract: A mechanical fuel pump includes first and second flexible members disposed within a pump body. The first flexible member is deflected in timed sequence with a rotating engine member. Deflection of the second flexible member is limited to select the amount of fuel expelled from the pump for each engine cycle. A stop member is movable in response to movement of an engine governor and throttle to result in increased fuel and air being supplied when the engine encounters a load.Type: GrantFiled: May 9, 2000Date of Patent: February 19, 2002Inventors: Lawrence W. Evers, William J. Towne, Jeremy S. Carlson

Patent number: 6347615Abstract: A tap-changer vacuum switch having an actuating rod extending and displaceable along an axis is provided with a damper having a damper housing offset from and fixed relative to the vacuum switch, and a rod piston fixed on the valve-actuating rod, in the damper housing, and defining in the damper housing a compartment whose volume changes as the rod piston moves axially with the rod. The damper housing is formed with a pair of radially open ports opening into the compartment. An in-only check valve fitted to one of the ports only permits fluid flow into the compartment, and an out-only check valve fitted to the other port only permits fluid flow out of the compartment.Type: GrantFiled: July 6, 2000Date of Patent: February 19, 2002Assignee: Maschinenfabrik Reinhausen GmbHInventors: Klaus Höpfl, Silke Wrede

Patent number: 6347616Abstract: The Solenoid Valve For A Vehicle Carbon Canister includes a housing with an outlet end and a inlet end. A portion of the inlet end of the housing extends around an inlet port formed in the inlet end to create an air inlet tube. Inserted in the outlet end of the housing is an end cap formed with an outlet port. The end cap extends around the outlet port to form an air outlet nipple having an internal portion and an external portion. Formed around the internal portion of the air outlet nipple is an annular cavity. Disposed within the housing is a solenoid mechanism slightly smaller than the housing to form an annular air passage having sufficient area to provide the proper air flow, but also having a thickness small enough to prevent carbon particles from passing through the annular air passage. A continuous air passage is formed by the air inlet tube, the annular air passage, and the air outlet nipple. A plunger is included to block the flow of air through the air outlet nipple.Type: GrantFiled: May 10, 2000Date of Patent: February 19, 2002Assignee: Delphi Technologies, Inc.Inventors: Lorenzo Guadalupe Rodriguez, Luis A. Flores-Mena, Alberto Alcantara, Yingjie Lin

Patent number: 6347617Abstract: Disclosed herein is an evaporative emission control system which can prevent changes in fuel component in the fuel tank and vacuum boiling in the fuel pump to thereby accurately control the air-fuel ratio to a desired value and ensure smooth supply of the fuel. The control system includes an evaporative fuel passage for connecting a fuel tank and an intake system of an internal combustion engine, and a control valve is provided in the evaporative fuel passage for opening and closing the evaporative fuel passage. It is determined whether or not a fuel temperature is higher than or equal to a predetermined fuel temperature. If the fuel temperature is higher than or equal to the predetermined fuel temperature, the opening operation of the control valve is disabled.Type: GrantFiled: June 29, 2000Date of Patent: February 19, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Toru Kitamura, Norio Suzuki, Naohiro Kurokawa, Tetsuya Ishiguro, Takeshi Suzuki, Toshiaki Ichitani

Patent number: 6347618Abstract: Disclosed is an intercooler system which uses an air conditioner evaporator coil or other mechanical refrigeration device to cool air flowing therethrough prior to intake of the air by an internal combustion engine. The invention thereby reduces the temperature of the air entering the engine well beyond the temperature reduction provided by a conventional intercooler. The invention may be used to chill the air to a point cooler than ambient temperature or even down to below freezing. In some embodiments, a conventional intercooler may be used to partially cool the air before it enters the intercooler of the invention. In other embodiments, the intercooler may be used in combination with a novel engine-driven supercharger having a variable-speed drive. The engine-driven supercharger of the invention may alternatively be used independently of the disclosed intercooler.Type: GrantFiled: July 28, 2000Date of Patent: February 19, 2002Assignee: Klem Flying Boats, L.P.Inventor: Richard H.

Patent number: 6347619Abstract: Exhaust gas recirculation is provided in a turbocharged diesel engine by adding a separate EGR manifold and a secondary exhaust valve for each combustion chamber that permits passage of exhaust gas from the combustion chamber to the EGR manifold. The secondary exhaust valve is opened during the expansion stroke of the engine cycle and sometime after the combustion process has been completed while the pressure in the combustion chamber is still greater than the pressure in the intake manifold. One or two EGR valves can be opened to admit the high pressure exhaust gas from the EGR manifold into the intake manifold. Decompression braking can be provided by an additional valve between the EGR manifold and the exhaust manifold that is opened to dump the gas from the EGR manifold to the exhaust manifold while the secondary exhaust valve in the cylinder head is opened at the beginning of the expansion stroke of the piston whereby the compressed air in the cylinder escapes before performing work on the piston.Type: GrantFiled: March 29, 2000Date of Patent: February 19, 2002Assignee: Deere & CompanyInventors: Todd Mathew Whiting, James Alan Eng, Jr.

Patent number: 6347621Abstract: A device for feeding projectiles to a gun barrel includes a hopper for containing projectiles for feeding to a housing. The housing has an outlet communicating with the gun barrel and an indexed loading disk mounted at the outlet over a flat housing floor. The loading disk has a number of projectile spaces for receiving projectiles, and the disk is selectively positionable at index positions with the spaces over the outlet to gravity feed projectiles into the gun barrel. A trigger assembly is coupled to the loading disk and includes a ratchet to engage fins on the disk to sequentially rotate the disk to the index positions to drop projectiles into the barrel. The trigger also includes a projection for substantially continually engaging a corresponding slot on the disk for holding and stabilizing the disk in the housing during operation. The device is configured to be used to sequentially load a single paintball to a blowgun by successive pulls of the trigger.Type: GrantFiled: October 12, 2000Date of Patent: February 19, 2002Inventor: Christopher L.
