Abstract: A valve stem which is located for axial movement; a valve lever is pivotally mounted at one end and is attached adjacent the other end to the end of the valve stem, the valve lever defines a track; a drive pin engages in the track the drive pin being mounted at one end of a first link the other end of the link being pivotally mounted about a fixed pivot, a second link is pivotally mounted at one end about moveable pivot, the first and second links being interconnected by an intermediate link pivotally attached to said first and second links at positions separated from their pivots, a drive link is pivotally connected at one end to the pivotal connection between the second link and intermediate link and at the other end to a crank, so that rotation of the crank will cause the linkage to oscillate and the drive pin to perform a reciprocating motion along an arcuate path; the trank has a first portion which is engaged by the drive pin when the valve is closed and coincides with the arcuate path of the drive pin and a second portion which diverges from the path of the drive pin, so that engagement of the second portion by the drive pin will cause the valve lever to move opening and closing the valve; and means being provided for movement of the pivot to vary the timing and duration of opening of the valve.

Abstract: A valve mechanism includes a poppet type valve, a valve lever pivotally mounted at one end and attached at the other end to the end of the stem of the valve, the valve lever defines a track in which is located a drive pin and a drive mechanism is arranged to drive the drive pin in oscillatory manner; the track has a first portion which, when the valve is closed is engaged by the drive pin and coincides with the path of the drive pin, and a second portion which diverges from the path of the drive pin so that when engaged by the drive pin movement of the drive pin will cause the valve lever to move, opening and closing the valve. Preferably the mean position of oscillation of the drive pin is adjustable so that the duration and amplitude of valve opening may be varied.

Abstract: In a cylinder lubrication system for a two-stroke engine, a plurality of lubricating oil supply openings (78) open out in the inner circumferential surface of the cylinder (42) at a point lower than a top ring (22b) of a piston (22) located at a bottom dead center. The lubricating oil supply openings are configured to provide a larger amount of lubricating oil in the thrust side and anti-thrust side of the cylinder than in a remaining part of the cylinder. Thereby, the consumption of lubricating oil and the emission of undesired substances can be minimized while providing an optimum lubrication of the sliding part between the piston and the cylinder.

Abstract: A continuously variable valve lift device for a vehicle is provided, which includes a drive shaft rotating in association with a crank shaft and having a drive cam formed on an outer periphery thereof, a locker arm shaft provided apart from the drive shaft and having one end that supports a rocker arm rotating and rocking in association with the drive cam, output cams rotatably installed on the drive shaft to interlock with the other end of the rocker arm, and a variable drive part straightly moving the rocker arm shaft in a vertical direction of the rocker arm shaft to vary a valve lift. When a valve is shifted from the high-lift state to the low-lift state, a pumping loss is reduced to improve the fuel consumption ratio. Also, since an advance function is provided, an exhaust-side CVVT can be deleted to greatly reduce the manufacturing cost.
