Abstract: A rocker arm is swingably supported by a control shaft that has an eccentric control cam formed thereon. The rocker arm is swung by a torque of a crankshaft of the engine. Two swing cams are swingably supported by a drive shaft and actuate respective engine valves to make an open/close operation of the same by receiving the swinging movement from the rocker arm. The rocker arm comprises a cylindrical base portion through which the control shaft passes; a first projected end that is provided at a first radially outside part of the cylindrical base portion in the vicinity of one axial end of the cylindrical base portion, the first projected end receiving the torque from the crankshaft for carrying out the pivotal movement of the rocker arm; and two second projected ends that are spaced from each other and provided at a second radially outside part of the cylindrical base portion, the second projected ends actuating the two swing cams when the rocker arm is swung. The first and second radially outside parts are opposite with respect to an axis of the cylindrical base portion.

Abstract: A vane rotor, a bush, and a press-fitting member are connected with a camshaft of an engine. The bush is supported by an inner surface of a front plate of a shoe housing. The press-fitting member is contact with an end surface of the camshaft. The bush and the press-fitting member are respectively press-fitted into both end surfaces of the vane rotor. Due to a press-fitting force difference between the bush and the press-fitting member, the vane rotor is slightly warped in a press-fitting direction of the bush to rotatably slide on an inner surface of the front plate.

Abstract: An internal combustion engine having a variable valve lift system whereby the engine can operate selectively in either of at least two valve lift modes, and a variable valve timing (VVT) system, as well as a method for controlling valve timing in such an engine are presented. The method comprises providing, in response to a valve lift mode shift, a control pulsing signal for the VVT actuator in order to compensate for the effects of the valve lift on the VVT system.

Abstract: A method for diagnosing malfunctions of switching valve lifters includes sensing variations in pressure of trapped oil in a drive chamber of a hydraulic camshaft drive, such as a cam phaser, comparing peak oil pressure readings in the drive chamber resulting from the increased torque of opening the valves of various cylinders of an engine and identifying cylinders having lower than normal valve opening pressure readings, indicating failure of an associated valve lifter to properly actuate a valve of the cylinder. Apparatus for indicating such malfunctions could include a cam phaser with pressure chamber, a pressure sensor connected to indicate pressure variations in the chamber; and a pressure indicator connected to the sensor and adapted to indicate actual pressure variations for comparison with normal variations to identify low pressure peaks indicating malfunction of a switching lifter. A computer could be used to receive and act upon the malfunction indications.

Abstract: Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.
