Abstract: A device and a method are provided for regulating the lift characteristic of a charge cycle valve of an internal combustion engine. The device comprises a controllable drive unit having an actuator element for actuating the charge cycle valve, two energy storage means acting on the charge cycle valve in opposite drive directions and a regulating means for controlling the drive unit. The regulating unit controls the drive unit according to a stored setpoint path, on the basis of which the charge cycle valve is transferred from a first end position into a second end position and vice versa. The setpoint path is designed so that it maps the ideal transient characteristic of the energy storage-drive element-energy storage system of the device without taking any additional ambient influences into account.

Abstract: Systems and methods for providing partial bleeder braking engine valve actuation are disclosed. In an embodiment of the present invention, a cam may be provided with a main exhaust lobe, a partial bleeder lobe and an inner base circle portion between the two lobes. A rocker arm including an internal rocker passage may be operatively connected to the cam. The rocker arm may contact a valve bridge at a central portion. The valve bridge may be operatively connected to first and second engine valves at its first and second ends, respectively. A slave piston incorporated into the first end of the valve bridge and a master piston may be incorporated into the central portion of the valve bridge. A hydraulic circuit may be provided between the master and slave pistons. A bleed hole may be provided above the slave piston. The master and slave pistons may be selectively actuated and the bleed hole may be selectively blocked and unblocked to provide partial bleeder braking as a result of the valve actuation motion imparted from the cam to the valve bridge through the rocker arm.

Abstract: The present invention relates to a variable valve operating device and a valve opening amount adjustment method, and can accurately control the amount of in-cylinder air and the strength of a swirl flow. The variable valve operating device according to the present invention includes a valve mechanism that can select a dual valve variable control mode in which the valve opening amounts of a first valve and a second valve, which are of the same type and provided for the same cylinder, can be varied continuously or in multiple steps. A valve opening amount difference is provided when the valve opening amounts are minimized in the dual valve variable control mode so that the valve opening amount of the first valve is larger than that of the second valve. In addition, adjustments are made so that the minimum valve opening amount of the first valve does not vary from one cylinder to another.

Abstract: The valve system for opposed piston engines essentially comprises a single poppet valve opening into the common combustion chamber between the two opposed pistons of each piston and cylinder pair. The engine for which the mechanism is adapted includes a rotating internal cylinder surrounding each piston pair, with a stationary outer cylinder or case surrounding the rotating cylinder. The valve is pivotally attached at one side or end thereof to the edge of the valve port of the rotating cylinder, and is actuated by an arm or arms having guides (rollers, etc.) at the distal end(s) thereof, which are captured in corresponding cam track(s) or channel(s) formed in the fixed outer cylinder or case of the engine. The cam track has a variable radius, with the valve arm(s) and guide(s) alternately lifting and lowering as the guide(s) travel(s) in the variable radius cam track(s), thereby closing and opening the valve.

Abstract: An engine that includes two intake and two exhaust valves for each cylinder is equipped for single valve constant lift engine braking. The exhaust valves may be actuated in a conventional manner via a rotating cam and a rocker arm coupled to a bridge that spans between the pair of exhaust valves. Engine braking is accomplished by actuating a brake actuator to hold one of the exhaust valves partially open, while the other of the two exhaust valves is allowed to close. Seating velocity of the non-braking valve is limited by including a second actuator button, namely a valve seating actuator, on the rocker arm that engages the valve bridge above the non-braking valve as it moves toward its closed position when the brake actuator is actuated.

Abstract: Surging is reliably prevented from occurring even when an engine with a turbocharger is operated with reduced number of cylinders and at a low speed range.Concerned is a method for controlling actuation of valves in an engine with a turbocharger, a variable valve mechanism 18 being arranged for controlling opening/closing timing and lifts of suction and exhaust valves (only exhaust valves 17 being shown in the figure) of each of cylinders 8, an operation with reduced number of cylinders being made possible by the variable valve mechanism 18 such that valve-opening action of suction and exhaust valves in part of the cylinders 8 is disabled to conduct the operation with the remaining cylinders 8. The exhaust valves 17 are opened substantially when a suction pressure is higher than an exhaust pressure in a suction stroke during the operation with the reduced number of cylinders at a low speed range, so that blown out amount of fresh air (suction air 4) to the exhaust side is increased to increase apparent exhaust flow rate and raise the level of the suction characteristic of the engine.
