A hydraulic valve lifter including venting means to assure venting of air through the lifter and filling thereof with oil during pre-start filling of the engine oil galleries after engine assembly. Patterning of a hemispherical pushrod seat surface, and/or patterning of either or both of the mating surfaces of a pushrod seat and a piston, permits air purged from the engine through a pushrod to be vented through the lifter. Such means may be temporary or permanent and may include coatings of the surfaces with materials that are destroyed by engine action after starting. Permanent means may include surface grooves in the mating surfaces and/or small-diameter passages between the hemispherical seat surface and the cylindrical outer surface of the pushrod seat. Venting means in accordance with the invention is useful for both valve-deactivating and non-valve-deactivating valve lifters.

Readily-fillable hydraulic valve lifter assembly

In a preferred embodiment, an engine coolant crossover assembly includes a crossover conduit member carrying an integral liquid cooled alternator and liquid cooled exhaust gas recirculation valve. The integration of one or both of these parts into the coolant crossover eliminates many parts from the total assembly. These parts include; attachment brackets, coolant hoses, hose clamps, cast mounting blocks, coolant tubes and attachment bolts. Reduction of these parts reduces system costs, assembly time, mass and potential coolant leak paths. A temperature sensor and a thermostat housing may also be included in the crossover assembly. The assembly may also be made part of an intake manifold for an integrated air fuel module of a V-type engine.

A hydraulic manifold assembly for variable actuation of engine valves. First and second plates have portions of flow passages integrally molded therein. The plates are formed preferably by injection molding of a suitable polymer, for example, glass-filled nylon, and are joined together as by cementing or preferably by fusion welding (vibration welding) along mating surfaces to form the full pattern of flow passages. This method of forming the manifold obviates the need for separate fasteners to connect the plates and for internal seals to form the flow passages. The assembly further comprises a retainer for retaining a plurality of individual solenoid-actuated valves in sockets formed in the plates. Preferably, the retainer is formed to function simultaneously as a positive crankcase ventilation (PCV) baffle that attaches to the plates via integrally molded releasable snap tabs. The present manifold results in a weight savings and a substantial savings in manufacturing cost over a prior art manifold formed of cast aluminum.

An integrated air fuel module ( ) for an internal combustion engine reduces or eliminates the escape of hydrocarbon evaporative emissions from the integrated air fuel module ( ) system, sub systems and components. The integrated air fuel module ( ) includes containment means ( ), such as a valve ( ) or carbon adsorber, that blocks the escape of evaporated hydrocarbon emissions from the air inlet ( ) of an engine during engine off conditions. The module ( ) provides a reduced number of potential external hydrocarbon leak and permeation paths to the surrounding atmosphere. Preferred geometries of the intake manifold ( ) in the module ( ) with the internal integration of other normally external systems, such as fuel injection ( ) and positive crankcase ventilation ( ) systems, accomplish the containment of evaporative emissions within or entering the air fuel module ( ) between engine operating periods when the engine is shut down.

A fuel injector includes a body having a nozzle end and a connector end. The body defines a side feed opening disposed between said nozzle end and said connector end. An injection assembly is disposed in the nozzle end and includes an actuating coil, a value actuated by the coil, and a valve seat operably associated with the valve.

Side feed fuel injector and integrated fuel rail/intake manifold

An integrated fuel delivery module for a fuel injected engine includes a fuel rail having a fuel distribution channel and a plurality of spaced-apart fuel injector sockets connected with the fuel distribution channel. A high-pressure fuel pump has a high-pressure chamber connected internally to the fuel distribution channel without external high-pressure fuel lines.

A remote control lever module comprising a shaft rotatably mounted on a support. A friction pad has a pair or surfaces each of which frictionally resists rotation of the shaft with respect to the support and permits relative rotation between the shafts and the support. A bearing assembly is loosely fit about the shaft to assure that the shaft may rotate in the support.

Remote control lever module

A remote control lever module comprises an inner shaft coaxially located inside an outer shaft. The inner and outer shafts are rotatably mounted on a support and can rotate with respect to one another. A return mechanism is engageable with the inner and outer shafts enabling forward rotation of the inner shaft to cause forward rotation of the outer shaft. The return mechanism further enables extended forward rotation of the inner shaft with respect to the outer shaft, and urges backward rotation of the inner shaft to a rearmost position. The return mechanism limits backward rotation of the inner and outer shafts beyond a nonactuating position. A force spring urges the outer shaft to the nonactuating position. Sensors produce electrical signals proportional to the angular position of the inner and outer shafts. A friction pad can be disposed between the inner shaft and support to frictionally resist rotation of the inner shaft with respect to the support.

A valve assembly for regulating air flow to an internal combustion engine comprises a valve body having a valve bore forming an induction passage, and a shaft extending across the valve bore. A valve member is secured to the shaft for rotation in excess of 90 degrees between a nonactuating position and a maximum actuating position. The valve member passes through a zero degree position when rotated from the maximum actuating position to the nonactuating position. The flow area around the valve member when in the zero degree position is less than the flow area when the valve member is in the nonactuating position. A return mechanism urges the valve member toward the nonactuating position when the valve member is rotated away from the nonactuating position.
