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 number of engine operating strategies have been developed that allow for engine braking when combustion is not needed. In these strategies, air within the engine cylinder is compressed by the cylinder piston; however, rather than introducing fuel into the cylinder to facilitate a combustion event, the cylinder is opened to an exhaust manifold and the compressed air is vented, and the energy is released by the engine. However, it has been learned that the venting of this compressed air from the engine can produce undesirable noise emissions. Thus, the present invention employs a dual exhaust valve lift strategy to reduce noise produced during engine braking while still allowing relatively high engine braking horsepowers to be achieved.

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： Engine compression release brakes include some degree of lash between the brake actuation portion and the engine exhaust valve portion. The disclosed apparatus and method provides an integral lash adjuster that includes an adjusting screw that is threadably received by a slidable plunger. Rotation of the adjusting screw causes the plunger to slide relative to a plunger cavity and responsively modify the amount of lash.

摘要： A system for controlling boost pressure at various different altitudes of operation of a turbo charged internal combustion engine includes a wastegate valve, an actuator, and a controller. Signals delivered from an engine speed sensor, a boost pressure transducer, a barometric pressure sensor, and a turbocharger speed sensor are processed in the controller. A control signal delivered from the controller to the actuator controls the position of the wastegate valve, bypass of exhaust gasses, and the speed of the turbocharger. The controller is configured to compare the turbocharger speed to a predetermined threshold value and determine the control signal based on the comparison.

The valve actuation system may also have a first cam element mechanically coupled to move the engine valve, and a first hydraulic slave piston operatively connected to the engine valve to move the engine valve independent of movement of the first cam element. The valve actuation system may further have a high pressure rail fluidly connected to the first hydraulic piston, and a control valve disposed between the high pressure rail and the first hydraulic piston to regulate movement of the engine valve.

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.
