    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: An engine valve actuator providing Miller cycle benefits and a method of operating an engine valve actuator are disclosed. The valve actuator employs a first force to hold an exhaust valve of the engine open during an exhaust stroke and a second, stronger force to hold the exhaust valve open during a compression stroke. The valve actuator may be operated using pressurized fluid adapted to extend an actuator piston through a cylinder. The first force may be derived by a mechanically driven actuator, while the second force may be derived from a high pressure rail of the engine. A low pressure source of the engine may be used to fill the actuator cylinder, with the high pressure rail only being placed into fluid communication with the cylinder when desired. A control valve may be employed to direct either the low pressure or high pressure fluid to the valve actuator cylinder.

    Abstract: An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A check valve is disposed between the directional control valve and the source of fluid, only allowing fluid flow from the fluid source to the directional control valve. A bleed orifice may be disposed between the directional control valve and the source of fluid, in parallel with the check valve.

    Abstract: An enhanced braking mode for a work machine includes activating engine compression release brakes while placing a torque converter in an overspeed condition. By doing so, both the engine and the torque converter contribute to decelerating the work machine. This combined braking horsepower is greater than that available using the engine compression release brakes with the torque converter in a locked condition. In addition, the braking horsepower available in this enhanced braking mode is comparable to that available with the employment of hydraulic retarders, which can be substantially more expensive, and require additional hydraulic cooling system capability. The enhanced braking mode is preferably carried out automatically by the electronic control module when the vehicle is in a retarding mode.

    Abstract: Compression brake systems using “back-fill” between combustion cylinders or requiring an exhaust valve to be opened twice during a braking cycle require brake actuation systems able to maintain control over the exhaust valve during different loading conditions. In a first opening event where a piston is at or near bottom dead center, pressures in the combustion cylinder are low. During a second opening event near top dead center pressures are higher. Movement of the exhaust valve may be slowed during the first opening event by controlling fluid leaving a second actuator volume opposite a first actuator volume providing opening force on an exhaust valve.

    Abstract: Compression brake systems using “back-fill” between combustion cylinders or requiring an exhaust valve to be opened twice during a braking cycle require brake actuation systems able to maintain control over the exhaust valve during different loading conditions. In a first opening event where a piston is at or near bottom dead center, pressures in the combustion cylinder are low. During a second opening event near top dead center pressures are higher. Movement of the exhaust valve is controlled by delivery of fluid to a brake actuator piston. Fluid delivery is slowed as the brake actuator piston moves to cover a first cylinder port and uncover a second cylinder port.

    Abstract: In one aspect, the present disclosure is directed to an internal combustion engine having an engine block defining at least one cylinder and a head connected with said engine block. The head has an air intake port and an exhaust port. The internal combustion engine also has a piston and a combustion chamber. The internal combustion engine further has an air intake valve movable to open and close the air intake port and an air supply system having at least one turbocharger fluidly connected to the air intake port. The internal combustion engine additionally has a fuel supply system operable to inject fuel into the combustion chamber, a cam assembly selectively mechanically linked to the air intake valve to move the air intake valve, and an electromagnetic actuator configured to decouple the cam assembly from the air intake valve and control movement of the air intake valve.

    Abstract: An engine with an efficient valve actuator is disclosed. The engine employs a first force to hold a valve of the engine open during a normal valve event and a second force to hold the exhaust valve open during an exhaust gas recirculation event. The valve actuator may be operated using pressurized fluid adapted to extend an actuator plunger through a cylinder. The first force may be derived by a mechanically driven actuator, while the second force may be derived from a high pressure rail of the engine. A control valve may be employed to direct either low pressure or high pressure oil to the valve actuator cylinder.
