    Abstract: An internal combustion cylinder assembly includes a cylinder having a combustion chamber and a piston. An intake valve provides a working fluid to the combustion chamber while the piston moves from a top dead center position to a bottom dead center position. A pre-combustion chamber is connected communicably to the combustion chamber via a Suder valve and conveys a portion of the working fluid to the pre-combustion chamber while the Suder valve is substantially open. The Suder valve may open substantially simultaneously with the intake valve, remain substantially open while the piston moves from the top dead center position to the bottom dead center position during an intake stroke, and close substantially while the piston is returning to the top dead center position during a compression stroke.

    Abstract: Valve mechanism in an internal combustion engine, includes a valve play-take up mechanism in the form of a piston in a cylinder chamber at one end of an exhaust rocker arm, and a hydraulic circuit with valve elements for supplying or draining off pressure fluid to and from the cylinder chamber. A second cylinder chamber with a piston acting in an opposite direction is arranged in the rocker arm and communicates with the first-mentioned cylinder chamber. A brake rocker arm is mounted on the same rocker arm shaft as the exhaust rocker arm and has an outer end, which acts against the piston in the second cylinder chamber. The brake rocker arm has its own cam element with brake cam lobes to one side of the exhaust rocker arm cam element.

    Abstract: A valve timing control system for an internal combustion engine, which is capable of accurately and delicately controlling an amount of intake air, and thereby maintaining excellent combustion state and reduced exhaust emissions. The valve timing control system variably controls the valve-closing timing of an intake valve with respect to valve-opening timing of the same as desired via a variable intake valve actuation assembly. The ECU of the engine determined a basic value of a target auxiliary intake cam phase according to the demanded drive torque of the engine. The ECU calculates a control input to the variable intake valve actuation assembly such that the cylinder intake air amount converges to a target intake air amount and at the same time the auxiliary intake cam phase is constrained to the basic value of the target auxiliary intake cam phase.

    Abstract: A variable valve actuation system for providing discrete exhaust and intake valve lift profiles for various operating modes of an internal combustion engine. The variable valve actuation system includes exhaust and intake rocker assemblies, exhaust and intake hydraulic extension devices operatively coupling corresponding rocker assemblies with respective engine valves and exhaust and intake control valves for selectively supplying the pressurized hydraulic fluid to the extension devices so as to independently switch them between a pressurized condition and a depressurized condition. The engine further includes an exhaust brake provided to initiate a small lift of the exhaust valve during the engine braking operation while the exhaust extension device maintains the exhaust valve open during a compression stroke for bleeder-compression release braking. The exhaust and intake valves can be adjusted independently to provide combinations of valve lift modes.
