摘要： An engine includes an engine casing that defines a hollow piston cavity separated from an exhaust passage and an intake passage by a valve seat. A gas exchange valve member is positioned adjacent the valve seat and is moveable between an open position and a closed position. The gas exchange valve member also defines an opening that opens into the hollow piston cavity. A needle valve member is positioned in the gas exchange valve member adjacent a nozzle outlet and is moveable between an inject position and a blocked position. A port control valve member, which has a hydraulic surface, is mounted around the gas exchange valve member and moveable between an intake position and an exhaust position. A pilot valve is moveable between a first position at which the port control hydraulic surface is exposed to a source of high pressure fluid, and a second position at which the port control hydraulic surface is exposed to a source of low pressure fluid.

摘要： A first aspect of the present disclosure includes a method of controlling nitric oxides emissions. The method may include producing an exhaust gas stream containing NOx and supplying the exhaust gas stream to an exhaust passage. The method may further comprise supplying ammonia to the exhaust passage at a location upstream of a first selective catalytic reduction catalyst, wherein the amount of ammonia supplied at the first location is less than about 90% of the effective amount of ammonia needed for reduction of all NOx at the first location. Further, ammonia may be supplied to the exhaust passage at a second location downstream of the first selective catalytic reduction catalyst and upstream of a second selective catalytic reduction catalyst.

摘要： A servo control valve includes a valve body that defines a high pressure passage, a low pressure passage and a flow passage. A valve member has a first pressure surface in opposition to a control pressure surface. The valve member is positioned in the valve body and moveable between a first position in which the high pressure passage is open to the flow passage, and a second position in which the low pressure passage is open to the flow passage. A pilot member is positioned in the valve body and is moveable between an up position in which the control pressure surface is exposed to pressure in the high pressure passage, and a down position in which the control pressure surface is exposed to pressure in the low pressure passage. A spring is operably positioned to bias a valve member toward one of its first position and its second position.

摘要： An engine valve actuation system is provided. The engine valve actuation system includes an intake valve that is moveable between a first position to prevent a flow of fluid and a second position to allow a flow of fluid. A cam assembly is configured to move the intake valve between the first position and the second position. A fluid actuator is configured to selectively prevent the intake valve from moving to the first position. A source of fluid is in fluid communication with the fluid actuator. A directional control valve is configured to control a flow of fluid between the source of fluid and the fluid actuator. A check valve is disposed between the directional control valve and the source of fluid, only allowing fluid flow from the fluid source to the directional control valve. A bleed orifice may be disposed between the directional control valve and the source of fluid, in parallel with the check valve.
