    Abstract: An apparatus for adjusting an engine valve. The valve is actuated by a cam on a camshaft. The cam has a cam surface that drives the valve by way of a follower. The radius of the cam surface varies in the axial direction in an angular section of the cam. A pulley surrounds one end of the camshaft. The camshaft is rotated relative to the pulley to change the valve timing and the camshaft is also moved axially to change the lift of the valve by changing the area of the cam surface engaged by the follower.

    Abstract: A variable valve timing and lift system comprises a camshaft having a rotary cam and a valve operating (VO) cam, and a control rod having an integral portion. The integral portion in the form of an eccentric cam supports a rocker arm. The rotary cam is fixed to the camshaft. The VO cam is in contact with a valve lifter for a cylinder valve of an engine. A torsion spring winds about the camshaft to apply a bias to the VO cam. The rocker arm has a first arm cooperating with the rotary cam and a second arm cooperating with a projecting radial lever of the VO cam. Under the action of the torsion spring, the lever of the VO cam is held in engagement with the second arm of the rocker arm and the second arm of the rocker arm is held in engagement with the rotary cam.

    Abstract: A valve train for driving an engine valve in an internal combustion engine. A pump having a pressure chamber compresses and supplies fuel to the engine. An intake camshaft has valve cams for selectively opening and closing the intake valves and a pump cam for driving the pump. The intake camshaft has a torque fluctuation as a result of driving the intake valves and as a result of compressing fuel by the pump. A timing belt connects a crankshaft to the intake camshaft. The pump cam has a phase with respect to the intake camshaft to reduce a composite of the torque fluctuation (the net torque fluctuation) generated in the intake camshaft by the intake valves and the pump. This improves the life of the timing belt.

    Abstract: An engine which employs a cam follower mechanism to reduce wear and reduce the size of an assembled engine. The cam follower mechanism utilizes guide rails located to reduce side thrust on the valve stem. The engine employs a high speed quill shaft to synchronize independent cam shafts existing in each of a plurality of interconnected engines. The engine is assembled using a single size fastener to provide a uniform stress gradient within the engine. The engines are interconnected utilizing O-ring seals. The engine provides a piston crown utilizing a connecting rod directly connected to the bottom surface of the piston crown. The piston crown is stabilized along the longitudinal cylinder axis by a rail guide. Connecting rods are provided which require less than one hundred eighty degrees (180.degree.) circumference of a crankshaft pin for support so that a plurality of connecting rods can be associated with a single crankshaft pin. A tabbed bearing fits under the plurality of connecting rods to provide lubrication between the connecting rods and the crankshaft pin. Connecting rods are held to the crankshaft pin by a circular retaining ring. The engine provides a separate cylinder head and cylinder which are attached via a circular deformable retaining band to form a metal to metal seal. The engine provides an independent lubrication system in each engine. Coolant or lubricant is provided to each engine in parallel so that the temperature of the coolant entering each engine is the same. A large diameter modular crankshaft is provided.
