Abstract: Internal combustion engines having multi-stage telescoping poppet valves in lieu of conventional poppet valves are disclosed. The engines may have pistons with a skirt with a field of pockets that provide a ringless, non-lubricated, seal equivalent. The piston heads may include one or more depressions and may be domed to facilitate the movement of air/charge in the cylinder. The engines may also have non-circular, preferably rectangular, cross-section pistons and cylinders. The engines also may include a split crankshaft. The engines may use the pumping motion of the engine piston to supercharge the cylinder with air/charge. The engines also may operate in an inverted orientation in which the piston is closer to the local gravitationally dominant terrestrial body's center of gravity at top dead center position than at bottom dead center position.

Abstract: A tappet assembly for use in translating force between a camshaft lobe and a fuel pump assembly via reciprocal movement within a tappet cylinder having a guide slot. The tappet assembly includes a bearing assembly having a shaft and a bearing rotatably supported by the shaft for engaging the lobe. An intermediate element has a shelf for engaging the fuel pump assembly, and a pair of arc-shaped bearing surfaces rotatably engaging the shaft when the bearing engages the lobe and the shelf engages the fuel pump assembly. The intermediate element includes a pair of lock apertures. The bearing assembly further includes a pair of shields supported on the shaft of the bearing assembly with the bearing interposed between the shields. The shields include a pair of opposing fingers for engaging the lock apertures so as to substantially retain the bearing assembly to the intermediate element and so as to substantially retain the shaft of the bearing assembly within the annular body in absence of engagement between the bearing and the camshaft lobe.

Abstract: A lash compensator for a valve train component of an internal combustion engine is provided that includes an end-cap arranged within a reverse-spring control valve assembly of an axially moveable piston. The piston has a first reservoir and an inner radial wall configured with a through-aperture. The reverse-spring control valve assembly has a control valve housing, a bias spring, an end-cap, and a closing body. The end-cap is configured with a cupped end; an inner side of the cupped end receives a second lower end of the bias spring, and an outer side of the cupped end engages an upper portion of the closing body. The end-cap minimizes or eliminates the variation in flow resistance caused by a variation in end-coil geometry of the second lower end of the bias spring.

Abstract: A compression-release brake system is provided that includes a lost motion exhaust rocker assembly, an actuation piston, and a reset device. The actuation piston includes an actuation piston body that is slidably received by the rocker arm to define a piston cavity in the rocker arm and is movable between piston retracted and extended positions. The actuation piston is configured to be operatively associated with the exhaust valve to permit unseating of the exhaust valve from the seated state. An actuation piston check valve is configured to move between closed and open positions to permit hydraulic fluid flow through an actuation piston communication port to the piston cavity. The reset device includes a reset check valve and a reset pressure control spring for applying a biasing force to the reset check valve to urge the reset check valve toward an open position.
