The gear assembly further includes a sub-gear co-axially disposed relative to the main gear with a resilient member disposed therebetween. The sub-gear including a second hub, a second gear ring positioned about the second hub, and a second helically splined region complementary to the first helically splined region.

Scissors gear assembly

A transmission system includes a crankshaft having an outer surface with a plurality of splines and a hub having an inner surface with a plurality of splines. The hub is mounted on the crankshaft such that the plurality of splines on the inner surface of the hub meshes with the plurality of splines on the outer surface of the crankshaft. The transmission system further includes a flywheel mounted to the hub.

Transmission system and associated engine

An internal combustion engine includes an engine block defining at least one row of cylinders extending from a first end toward a second end. The internal combustion engine also includes a front housing attached to the first end of the engine block. An idler gear assembly includes an idler gear rotatably mounted on a stub shaft and has a first attachment to the engine block and a second attachment to the front housing. A thrust plate is positioned between the front housing and the idler gear assembly and includes an annular thrust surface, a pair of sealed fastener device openings, and an unsealed lubrication opening.

A fuel delivery assembly for delivering a flow of fuel to a fuel injector includes a securing member including a securing member opening extending through the securing member such that the securing member is generally cylindrical. The securing member opening includes an inner surface that includes a securing member projection. The fuel delivery assembly also includes a quill tube including a quill tube opening extending through the quill tube such that the quill tube is generally cylindrical. The quill tube opening is configured to receive the flow of fuel and direct the flow of fuel to the fuel injector. The quill tube includes an outer surface that includes a quill tube projection. The securing member opening is configured to receive at least a portion of the quill tube, and the securing member projection and the quill tube projection are configured to engage in an interference fit.

Fuel delivery assembly

A thermostat assembly for a combustion engine having at least one cylinder is disclosed. The assembly has a cylinder head configured to cap off the at least one cylinder, the cylinder head having a recess fluidly connected to a coolant passage of the combustion engine. The assembly also has a thermostat located completely within the recess.

Thermostat assembly having integral cylinder head and thermostat housing

An engine cylinder liner is provided. The engine cylinder liner includes a first liner end, a second liner end, and an inner surface extending between the first liner end and the second liner end. The engine cylinder liner also includes a first outer surface between the first liner end and a first outer surface end portion, and a second outer surface between the second liner end and a second outer surface end portion. The second outer surface end portion is closer to the first liner end, than the first outer surface end portion is to the first liner end. The engine cylinder liner further includes an inclined shoulder surface portion between the first and second outer surface end portions.

A condensation dispersion device for use with a power source having an exhaust recirculation system is disclosed. The condensation dispersion device may have a housing with an inlet configured to receive exhaust, and an outlet configured to discharge exhaust. The condensation dispersion device may also have a first static mixing device disposed within the housing and being configured to redirect condensate from an internal wall of the housing into the exhaust.

EGR equipped engine having condensation dispersion device

A valve actuation system for a combustion engine is provided. The valve actuation system may have an engine valve movable between first and second spaced apart end positions. The valve actuation system may also have a first cam element mechanically coupled to move the engine valve, and a first hydraulic slave piston operatively connected to the engine valve to move the engine valve independent of movement of the first cam element. The valve actuation system may further have a high pressure rail fluidly connected to the first hydraulic piston, and a control valve disposed between the high pressure rail and the first hydraulic piston to regulate movement of the engine valve.

Variable engine valve actuation system having common rail

A valve actuation system for an engine is provided. The valve actuation system can include two or more engine cylinders, each cylinder having at least one intake valve configured to control air-flow into each of the two or more cylinders and at least one exhaust valve configured to control the flow of exhaust gases out of each of the two or more cylinders. The at least one first cylinder includes an exhaust cam lobe configured to control the valve timing of an exhaust valve of the at least one first cylinder and to cause an exhaust valve of a second cylinder to open during an expansion stroke of the second cylinder.

Valve actuation system for internal combustion engine

A cylinder head of an engine is disclosed, the cylinder head including an upper deck, a lower deck, and a sidewall extending between the upper deck and the lower deck. The lower deck defines a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion. An engine is also disclosed that includes a cylinder block having a cylinder bore, and a piston slidably positioned within the cylinder bore. The engine also includes a cylinder head having a lower deck connected to the cylinder block, the lower deck defining a block-engaging portion and a combustion chamber flame deck. The combustion chamber flame deck is spaced apart from the block-engaging portion by a recess.

Engine cylinder head

A regeneration assembly includes a first portion including a combustion chamber connected to a combustor head. The regeneration assembly also includes a second portion including a housing. The first portion is removably connectable to the second portion.

Regeneration assembly

A valve actuation system is provided. The system has an engine valve moveable between a first position at which the engine valve prevents a flow of fluid relative to the engine valve and a second position at which fluid flows relative to the engine valve. The system also has a first cam adapted to move the engine valve from the first position to the second position during a first lift period in response to a rotation of the first cam. The system has a second cam adapted to move the engine valve from the first position to the second position during a second lift period in response to a rotation of the second cam. The system also has a cam following assembly disposed between the first and second cams and the engine valve. The cam following assembly is adapted to selectively connect one of the first and second cams with the engine valve to thereby move the engine valve through one of the first and second lift periods.

Engine valve actuation system

Engine compression release brakes include some degree of lash between the brake actuation portion and the engine exhaust valve portion. The disclosed apparatus and method provides an integral lash adjuster that includes an adjusting screw that is threadably received by a slidable plunger. Rotation of the adjusting screw causes the plunger to slide relative to a plunger cavity and responsively modify the amount of lash.

Integral lash adjustor for hydraulic compression engine brake

An apparatus and method for pumping oil in a machine. The apparatus and method includes a first gear drivably connected to the machine, a second gear connected to the machine such that a set of teeth located on the first gear engage a set of teeth located on the second gear, an oil inlet port located near the teeth of the first gear slightly before a point of engagement of the teeth of the first and second gears, and an oil outlet port located at the point of engagement of the teeth of the first and second gears.
