    摘要: Exhaust gas re-circulation is achieved internally in an internal combustion engine having intake and exhaust valves actuated by a camshaft. A controller monitors at least one engine parameter and automatically actuates an electrically actuated fluid operated brake actuator at a predetermined timing of movement of an engine piston to cause the actuator to maintain the exhaust valve at an intermediate position between a full open position and a closed position of the exhaust valve and cause exhaust gasses to be delivered from the exhaust manifold to the combustion chamber of the engine.

    摘要: 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.

    摘要: 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.

    摘要: A system and method for controlling combustion engine compression braking having the variable timing of the dwell period of at least one exhaust valve by an electronic control module within each one of the engine cylinders during a braking event as well as the variable timing of the commencement or onset of the braking event. The system and method thus facilitate the proper performance of the braking event as a function of engine speed and prevents interference or physical impact with the cam driving elements used for achieving the normal or regular exhaust valve event.

    摘要: A method of engine braking includes a initial step of determining whether fuel injector tip temperatures are at or above a pre-determined temperature. If the injector tip temperatures are below the pre-determined temperature, then the electronic control module commands performance of dual event engine braking. If the injector tip temperatures are at or above the pre-determined temperatures, then the electronic control module commands the performance of single event engine braking. Such a strategy can achieve higher overall engine braking horsepower without risking the potential catastrophic dangers associated with injector tip overheating.

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.
