Abstract:
A variable valve actuation system (72) is disclosed for providing exhaust to at least one component downstream of an engine. The system includes a supply (86) of low pressure fluid, an engine fluid sump (94), and an exhaust valve (66) disposed in an engine cylinder. The system also includes a hydraulic actuation system (98) operably connected to the exhaust valve of the engine cylinder and a braking control valve (84) operably connected to the hydraulic actuation system. The system further includes a device for accumulating fluid (148) and a device for fiuidly coupling (144) the hydraulic actuation system to the accumulating device.
