Abstract: A system for accomplishing engine exhaust braking and exhaust gas recirculation for an engine having an exhaust manifold and a plurality of exhaust valves per cylinder during a four stroke engine cycle is provided. The system includes an actuation device operable to provide valve actuation of a single exhaust valve for an exhaust braking event and an exhaust gas recirculation event. The exhaust valve is not completely closed during the exhaust braking event and the exhaust gas recirculation event. The exhaust braking event includes actuating a single exhaust valve beginning during a second half of a compression stroke and a first half of an expansion stroke, and closing the exhaust valve beginning during a second half of an exhaust stroke. The exhaust gas recirculation event includes reactuating the exhaust valve beginning during a first half of an intake stroke, and closings the exhaust valve beginning during a second half of the intake stroke. Since a single exhaust valve is actuated during the exhaust braking and exhaust gas recirculation events, the overall performance of the vehicle is increased.

Abstract: A valve opening arrangement includes a first contact surface on a first member, and a second contact surface on a second member discrete from the first member. A first and a second opening are provided, and a first and a second valve movable to open and close the first and second opening, respectively, are provided. A yoke is arranged to move the first valve and not the second valve when contacted by the first contact surface and is arranged to move the first valve and the second valve when contacted by the second contact surface.
