Abstract: The two-stroke engine has a plurality of intake passages extending from the external air inlet port through the crankcase, separating the intake air charge from the air and oil vapor within the crankcase. The piston has one or more corresponding inlet tubes depending therefrom that telescope within the crankcase intake passages as the piston reciprocates. All intake air travels through these passages and is separated from the remainder of the crankcase volume. The incoming air charge passes through a concentric poppet valve in the piston crown to enter the combustion chamber. Fuel is provided by conventional direct or port injection and ignition is provided by one or more conventional spark plugs. Diesel operation is achievable when the engine is configured appropriately. Exhaust exits the combustion chamber through a poppet valve in the cylinder head, the poppet valve being actuated by a rocker arm and pushrod from a crankshaft driven cam.

Abstract: A deactivation valve lifter includes a lifter body. The lifter body has a first end configured for engaging a cam of an engine and at least one annular pin chamber. A pin housing includes a pin housing bottom. The pin housing bottom defines at least one pin stop aperture and a radially directed pin bore. A deactivation pin assembly is disposed within the pin bore and includes pin members. The pin housing is concentrically disposed within the lifter body. A portion of each pin member may be disposed within the annular pin chamber to thereby selectively couple and decouple the lifter body to the pin housing. A drain aperture defined by the pin housing bottom extends from the pin bore to an outside surface of the pin housing. A stop pin is disposed in the at least one pin stop aperture for limiting the inward motion of the pin members.

Abstract: Apparatus and method are disclosed for converting an internal combustion engine from a normal engine operation (20) to an engine braking (or retarding) operation (10). The apparatus has an actuation means (100) containing two braking pistons (160) slidably disposed in the valve bridge (400) between an inoperative position (0) and an operative position (1). The apparatus also has a flow control valve (50) for supplying control fluid to the actuation means (100) with two levels of pressure. At the first level or lower pressure, the braking pistons (160) will stay in the inoperative position (0), and a gap (234) is formed between the valve bridge (400) and the exhaust valves (300) to skip the motion from the lower portion of the cam (230) for the normal engine operation (20). At the second level or higher pressure, the braking pistons (160) will be moved to the operative position (1), and a linkage is formed between the valve bridge (400) and the exhaust valves (300) so that the motion from the whole cam (230) can be transmitted to the valves (300) for the engine braking operation (10). The apparatus also includes a supporting means (250) for preventing any no-follow of the valve train components and a resetting means (150) for modifying the valve lift profile (220v) generated by the cam (230). The supporting means (250) does not impose any force on the braking pistons (160), while the resetting means (150) stays at the off or draining position during the normal engine operation (20).

Abstract: In a link type variable stroke engine in which a piston, a crankshaft and an eccentric shaft are linked by a linking mechanism, a counterweight part which is provided so that in a projection view on a plane orthogonal to an axis of a rotary shaft, a center of gravity of the counterweight part is located on an opposite side of the axis of the rotary shaft from an axis of the eccentric shaft rotates together with the rotary shaft. Accordingly, it is possible to effectively suppress and lessen half-order inertial exciting force occurring at the eccentric shaft.
