摘要： A two-step finger follower rocker arm assembly for cooperating with high-lift and low-lift cam lobes of an engine camshaft. The rocker arm assembly includes a follower body for engaging an hydraulic lash adjuster and a valve stem. A central well contains a roller for following the central low-lift cam lobe. Pivotably mounted on the body are lateral high-lift followers, including sliders or rollers, for following the lateral high-lift cam lobes. A latch block disposed on the body surface is slidable by piston and spring means between first and second positions to engage and thereby alternatively latch and unlatch the high-lift followers. In latched position, the rocker arm assembly acts in high-lift mode; in unlatched position, in low-lift mode.

摘要： a generally conventional lash adjuster is modified by incorporating a coaxially oriented hydraulic control piston assembly within the guide body. The control piston normally fixes latch means, such a plurality of hard spheres, in multiple detents loaded in compression with the other components, to provide a rigid stop, but when the control piston is hydraulically pressurized, the detents are overcome and the piston assembly provides a resilient or soft stop that accommodates extended displacement (retraction) of the lash adjuster within the guide. The hydraulic actuation is preferably implemented with a three-way solenoid valve or the like, for controlling high-pressure oil to a gallery and associated inlet ports for the control piston assembly. In the typical implementation of the invention, the piston need have only two operational positions-denergized to establish the detent or hard stop condition, or fully energized to establish the valve deactivation position. With all of preferably four detents in quadrant symmetry and associated components in compression, side loading is avoided. Moreover, with the present invention, backlash is also avoided.

摘要： In a rockable-cam equipped reciprocating internal combustion engine, a rockable cam is rotatably fitted on the outer periphery of an intake-valve drive shaft that is rotatable in synchronism with rotation of a crankshaft. The rockable cam oscillates within predetermined limits during rotation of the intake-valve drive shaft so as to directly push an intake-valve lifter. As viewed from an axial direction of the crankshaft, an axis of the intake-valve drive shaft is offset from a centerline of the intake-valve stem in a first direction that is normal to both the cylinder centerline and the crankshaft axis and directed from the cylinder centerline to the intake valve side. The crankshaft axis is also offset from the cylinder centerline in the first direction.

摘要： A drive train for an overhead valve engine, including a cam gear driven by the crankshaft, the cam gear supported for rotation in the cylinder block externally of the cylinder head and having a cam lobe mounted thereon for actuating a pair of rocker arms mounted for rotation in the cylinder head, which in turn actuates intake and exhaust valves in the cylinder head. A first lubrication passageway is provided in the crankcase of the engine to communicate oil, pumped from the oil sump by a combination oil pump and governor assembly driven from the crankshaft, to the upper crankshaft bearing. A second lubrication passageway is provided in the crankshaft and communicates oil from the upper crankshaft bearing to the coupling between the crankshaft and the connecting rod. An air cleaner body includes an integrally formed fitting extending therefrom, which fits within an opening in the breather cover to directly communicate the breather chamber with the air cleaner, wherein the air cleaner body may be mounted to the cylinder block in an easy, one-step operation in which the fitting is inserted into the breather cover opening and the air cleaner body is fastened directly to a mounting flange of the carburetor.
