Abstract: A desmodromic valve system which provides direct bidirectional displacement of a valve stem of an internal combustion engine without the aid of a rocker arm, utilizing a semirigid basket operating in conjunction with a plurality of cams for each valve. The basket is disposed about the camshaft of the engine and secured to the valve stem by an integral retainer on a bottom portion of the basket, and is constrained to motion along the valve stem axis. The basket has a pair of downwardly oriented cam followers in the upper portion thereof, spaced apart from the valve stem axis. A central cam and a parallel pair of side cams are fixedly mounted on the camshaft so as to rotate therewith, the cams substantially surrounded by the basket and cooperating therewith to provide reciprocating valve action with positive bidirectional drive. The central cam is aligned with the valve stem axis, and the side cams are spaced apart from the valve stem axis, parallel to the central cam and respectively aligned with the cam followers. During a first part of a valve cycle, the central cam pushes the valve stem down so as to positively open the associated valve, and the valve stem pulls said basket down with it via the retainer. During a second part of the valve cycle, the side cams push the basket up via their respective cam followers and thereby cause the basket to pull the valve stem so as to positively close the valve.

Abstract: A camshaft assembly including a target wheel is manufactured using an assembly process in which the camshaft is formed from a hollow tube. After the cam rings and a target wheel ring have been correctly positioned on the hollow tube, the tube is pressurized to expand its diameter, locking the rings into position on the tube. Locating the target wheel along the axis of the camshaft and spaced from the camshaft end allows the sensor to be located along the axis of the camshaft, and precludes the need to increase the overall length of the head to accommodate the target wheel and the sensor. In a dual overhead engine, the target wheels may be mounted on the two camshafts so that they may be read by a dual element sensor that is mounted between the two wheels.

Abstract: A method for calibrating a distance sensor of a rotary actuator device for controlling a valve of an internal combustion engine. The rotary actuator includes an electric motor with an actuator element for actuating the valve, two energy storage means acting on the valve in opposite drive directions, and a control unit for controlling the electric motor. The electric motor is controlled such that the valve is transferred from a first end position, in which the actuator element is a metastable torque-neutral position, to a second metastable torque-neutral position. Starting from a torque-neutral position, the electric motor is controlled such that the rotor is moved out of the torque-neutral position in at least one direction by a distance, and the resulting electric motor power consumption is measured. Depending on the electric motor current values, a new rotor position for calibration of the distance signal is ascertained.

Abstract: A rocker arm mechanism opens and closes an intake valve. The intake valve is driven by cam of a cam shaft. The rocker arm mechanism is provided in each of bank. The rocker arm mechanism has a structure which changes a phase of the intake valve while displacing a portion driven by the cam to a circumferential direction of the cam shaft. A structure provided with an inversion mechanism inverts a rotating direction of the camshaft of one bank with respect to a rotating direction of the camshaft of the other bank. A variable valve unit having the simple and same structure can be used in both banks. A phase is varied so that a valve closing timing is set larger than a valve opening timing for each bank.

Abstract: A twin cylinder engine, includes a pair of cylinder members mounted to mounting surfaces of a crankcase, and cylinder heads mounted to the cylinder members. The cylinder members are modular components, which may be pre-assembled with components of the valve train as packaged units before the cylinder members are attached to the crankcase. Each cylinder member rotatably supports a cam gear which extends into the crankcase for driving engagement with the crankshaft. The cylinder members may be configured for either side valve-type (nullL-headnull), or overhead valve-type (nullOHVnull) engines, and the cylinder members may also be used in single cylinder engines.
