摘要： A variable valve actuation system is disclosed for providing exhaust to at least one component downstream of an engine. The system includes a supply of low pressure fluid, an engine fluid sump, and an exhaust valve disposed in an engine cylinder. The system also includes a hydraulic actuation system operably connected to the exhaust valve of the engine cylinder and a braking control valve operably connected to the hydraulic actuation system. The system further includes a device for accumulating fluid and a device for fluidly coupling the hydraulic actuation system to the accumulating device.

摘要： A compression brake system of an internal combustion engine includes a mechanical system for coupling a camshaft to a brake actuator assembly. The mechanical system includes a stationary housing defining an aperture and a lifter is slidably disposed in the aperture. A resilient element is disposed between the housing and the shoulder and configured to bias the lifter toward the camshaft. The mechanical system is dedicated to compression braking, and therefore the camshaft may have a lobe optimized for braking.

摘要： A power system for use with an engine having at least one cylinder, and a piston, a fuel injector, and an exhaust valve associated with the at least one cylinder, is disclosed. The power system may have an exhaust passage, an aftertreatment component disposed within the exhaust passage, and a valve actuator configured to selectively move the exhaust valve. The power system may also have a controller in communication with the fuel injector and the valve actuator. The controller may be configured to make a determination to heat the aftertreatment component, to activate the valve actuator to hold open the exhaust valve as the piston moves through a top-dead-center position to disable the at least one cylinder based on the determination, and to activate the fuel injector to inject fuel into the at least one cylinder while the at least one cylinder is disabled.

摘要： A shock absorber has a biasing member located between the base cup of a reserve tube and a cylinder end at the bottom of a pressure tube. The biasing member urges the pressure tube away from the base cup of the reserve tube and provides for movement between the lower ends of the two members without affecting the seating or sealing of the components within the shock absorber. The movement between the pressure tube and the reserve tube provides axial compliance for accommodating tubes materials having different materials with different coefficients of thermal expansion.
