摘要:
A variable valve actuation system is disclosed for providing exhaust to at least one component downstream of an engine. The system includes an exhaust valve disposed in an engine cylinder and a hydraulic actuation system. The system also includes a braking control valve, a supply of hydraulic fluid operably connected to the hydraulic actuation system, and an exhaust valve actuating device operably connected to the valve actuation system. The exhaust valve actuating device is operable to affect the exhaust valve to open within the engine cylinder. The system further includes a device for controlling a position of the exhaust valve actuating device relative to a position of the exhaust valve. The controlling device is operably connected to the supply of hydraulic fluid.
