Patent number: 6732687Abstract: A generally conventional lash adjuster is modified by incorporating a coaxially oriented hydraulic control piston assembly within the guide body. The control piston normally fixes latch means, such a plurality of hard spheres, in multiple detents loaded in compression with the other components, to provide a rigid stop, but when the control piston is hydraulically pressurized, the detents are overcome and the piston assembly provides a resilient or soft stop that accommodates extended displacement (retraction) of the lash adjuster within the guide. The hydraulic actuation is preferably implemented with a three-way solenoid valve or the like, for controlling high-pressure oil to a gallery and associated inlet ports for the control piston assembly. In the typical implementation of the invention, the piston need have only two operational positions-denergized to establish the detent or hard stop condition, or fully energized to establish the valve deactivation position.Type: GrantFiled: March 12, 2003Date of Patent: May 11, 2004Assignee: Stanadyne CorporationInventor: Ilija Djordjevic

Patent number: 6732689Abstract: A valve timing control apparatus for an engine. Presence/absence of a torque demand (xtq) is estimated upon starting of a lock pin release control to thereby alter a change rate (&bgr;) of a target phase angle in dependence on presence/absence of the torque demand (xtq). Unless torque demand is issued, the change rate is set to a small value (&bgr;2) for suppressing the change of the target phase angle (&thgr;t) after detection of release of the lock pin in order to avoid a shock unexpected by a driver. When the torque demand is issued, the change rate is set to a large value (&bgr;1) for allowing the target phase angle to approach speedily to a base target phase angle (&thgr;map) for thereby minimizing a delay in response involved in the phase angle detection through the lock pin release control.Type: GrantFiled: October 28, 2002Date of Patent: May 11, 2004Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Koji Wada, Tatsuhiko Takahashi

Patent number: 6732690Abstract: A torque bias coil spring for a camshaft phaser disposed on the outside of a cover plate for the rotor chamber and connected between the stator and rotor for angularly biasing the rotor. A rotor extension, such as a sleeve for a locking pin mechanism or a target wheel unit, extends from the rotor chamber through an opening in the cover plate for engaging a first spring tang. The second tang of the spring is engaged by a phaser binder bolt. The spring thus is able to follow the rotary motion of the rotor within the rotor chamber and to bias the rotor toward a predetermined rotational extreme.Type: GrantFiled: April 23, 2003Date of Patent: May 11, 2004Assignee: Delphi Technologies, Inc.Inventors: Ronald J.

Patent number: 6732691Abstract: A camshaft phaser control system including a camshaft target wheel, the target wheel having first and second teeth for measuring camshaft oscillatory instability. The trailing edge of the first tooth coincides with the negative camshaft oscillation peak, and the trailing edge of the second tooth coincides with the positive camshaft oscillation peak. During each camshaft rotation, each tooth initiates an input signal to generate first and second input signals in known fashion. During crankshaft rotation, a third input signal is generated corresponding to the rotational position of the crankshaft. From these signals, operational camshaft oscillatory instability is computed by an engine monitoring system (EMS). Any deviation from the operational instability while the engine is operating is a direct measurement of oscillatory instability of the camshaft about its nominal holding position. A change in oscillatory instability is inferred as system malfunction, permitting defensive action to be taken by the EMS.Type: GrantFiled: June 5, 2003Date of Patent: May 11, 2004Assignee: Delphi Technologies, Inc.Inventors: Jongmin Lee, Timothy M. Nieves, Jeffrey M. Pfeiffer, Amanpal S. Grewal

Patent number: 6732695Abstract: An intake manifold (10) for a multi-cylinder internal combustion engine includes a tubular intake distributor (12) from which a plurality of long intake tubes (13) extend and lead to the individual cylinders. Short intake tubes (14) likewise extend from the intake distributor and open into the respective associated long intake tubes (13). The intake distributor (12) and the long and short intake tubes (13, 14) are formed from a one-piece housing (11) which has a cavity (21) which intersects the short intake tubes (14). In this cavity (21) a control element (15) is installed, which includes flaps (16), flap frames (17), a shaft (19) and a control element frame (18). By moving the shaft (19) either rotationally or translationally, the short intake tubes (14) can be opened or closed. In contrast to arrangements known in the prior art, the control element (15) has no sealing elements which can catch or jam during assembly.Type: GrantFiled: February 4, 2002Date of Patent: May 11, 2004Assignee: Filterwerk Mann & Hummel GmbHInventors: Herbert Pietrowski, Thomas Jessberger, Ingo Koch, Helmut Neuschwander, Eckehard Mandel

Patent number: 6732696Abstract: An air intake duct system for internal combustion engines, and in particular for V-engines, comprises a plurality of air intake ducts (10, 12). Each air in-take duct is formed by two duct portions (18), and (20) and (22), respectively. The second duct portions (20, 22) are arranged to swivel about a swivelling axis (34) and (36), respectively, for varying the length of the air intake duct. According to the invention the two swivelling axes (34, 36) are supported in a common bearing part (44) which comprises two swivelling axis bearings each provided for one of the two swivelling axes (34, 36).Type: GrantFiled: July 12, 2002Date of Patent: May 11, 2004Assignee: Pierburg GmbHInventor: Hans-Juergen Huesges

Patent number: 6732699Abstract: A cast iron cylinder liner for an engine has a body with a radial upper flange and a generally cylindrical wall extending axially from an inner portion of the flange. An arcuate fillet is formed at a juncture between the upper flange and an exterior of the cylindrical wall. To strengthen the juncture of thin wall liners, for example with wall thickness less than 2.5 mm, a portion adjacent the fillet is laser hardened to a selected depth of the wall, thus increasing resistance to stresses created in the wall when the liner is installed and operating in an engine.Type: GrantFiled: October 4, 2002Date of Patent: May 11, 2004Assignee: General Motors CorporationInventors: Shekhar G. Wakade, Paul Noles Crepeau, Grant K. Tappen

Patent number: 6732700Abstract: An oil pump unit for an engine includes an improved construction. The pump unit includes a housing. A scavenge pump assembly is disposed in series with the feed pump assembly to be driven by the pump shaft. The feed and scavenge pump assemblies each defines end portions spaced apart from each other along the shaft axis. The housing defines a first inlet port and at least one outlet port at one of the end portions of the feed pump assembly, a second inlet port and a second outlet port at one of the end portions of the scavenge pump assembly, and at least a third inlet port at the other end portion of the scavenge pump assembly.Type: GrantFiled: August 13, 2001Date of Patent: May 11, 2004Assignee: Yamaha Marine Kabushiki KaishaInventor: Noboru Suganuma

Patent number: 6732701Abstract: An internal combustion engine, and method of distributing lubricant within an internal combustion engine, are disclosed. The internal combustion engine includes a crankcase having a floor, a pump supported by the floor, and a camshaft. The pump includes an inlet and an outlet. The camshaft has a cam, first and second camshaft ends, and an internal channel extending within the camshaft between the ends. The first end is supported by the pump or the floor. Rotation of the camshaft causes the pump to draw in lubricant via the inlet and to pump out at least some of the lubricant via the outlet. The outlet is positioned in proximity to the internal channel at the first camshaft end, so that at least some of the lubricant is pumped into the channel.Type: GrantFiled: July 1, 2002Date of Patent: May 11, 2004Assignee: Kohler Co.Inventors: Kevin G.
