    Abstract: An exhaust rocker assembly for operating an exhaust valve of an engine during a compression-release engine braking operation. The exhaust rocker assembly comprises an exhaust rocker arm and a self-contained compression brake control module (CBCM) mounted to the exhaust rocker arm and operatively coupled to the exhaust valve for controlling a lift and a phase angle thereof. The CBCM includes a casing, an actuation piston disposed outside the casing so as to define an actuation piston cavity, a reset check valve provided between the casing and the actuation piston, and a compression brake actuator disposed in the casing. The actuation piston reciprocates relative to the casing. The compression brake actuator includes a control piston. The control piston engages the check valve when deactivated so as to unlock the actuation piston cavity and disengages from the check valve when activated so as to lock the actuation piston cavity.

    Abstract: There is provided a variable valve apparatus including: a plurality of rocker arms; a coupling pin disposed in a housing hole of the rocker arm closer to one side; a release pin disposed in a housing hole of the rocker arm closer to the other side; a pressing member; a transmission member; and a push-back member disposed so as to push back the transmission member from the other side. The pressing member is configured to push the coupling pin into the housing hole of the rocker arm closer to the other side to couple the plurality of rocker arms. The transmission member is configured to push back the coupling pin into the housing hole of the rocker arm closer to the one side to release a coupling of the plurality of rocker arms.

    Abstract: A type II valve train assembly that selectively opens first and second intake valves and first and second exhaust valves is provided. The valve train assembly includes an intake rocker arm assembly and an exhaust rocker arm assembly. The valve train assembly is configurable for operation in any combination of activated and deactivated states of engine braking and cylinder deactivation. The exhaust rocker arm assembly includes a first exhaust rocker arm, a second exhaust rocker arm and an engine brake exhaust rocker arm. A first exhaust HLA is associated with the first exhaust rocker arm. A second exhaust HLA is associated with the second exhaust valve. An exhaust actuation assembly selectively actuates to alter travel of the first and second exhaust HLA's to change a state of cylinder deactivation between activated and deactivated.

    Abstract: A valve train for an internal combustion engine may include a cam shaft and a cam follower. The valve train may also include a first cam arranged on the cam shaft for conjoined rotation. The valve train may further include a second cam arranged on the cam shaft for conjoined rotation and axially adjacent to the first cam. The cam follower may be axially adjustable between a first position, in which the cam follower is drive-connected to the first cam, and a second position, in which the cam follower is drive-connected to the second cam. The cam follower may include a mechanical adjustment device interacting with the cam shaft for axially adjusting the cam follower between the first position and the second position.
