    Abstract: A quick connect fluid valve assembly comprises a housing, a flow passage insert, and a movable connector. The flow passage insert is disposed at least partially within the housing and is movable relative to the housing. The flow passage insert forms a flow path from a first end of the flow passage insert to a second end of the flow passage insert. The movable connector is disposed in fluid communication with the flow path of the flow passage insert and the movable connector has at least one orifice. The movable connector is movable between a forward fluid flow position that allows forward fluid flow within the flow path of the flow passage insert and a backward fluid flow position that prevents backward fluid flow within the flow path of the flow passage insert.

    Abstract: A unit fuel injector (30) has a nozzle (36) providing axial guidance of a needle (72) at points proximal and distal to a needle feed cavity (81). The needle has a multi-lobular formation (200) providing distal guidance of the needle while allowing fuel from the needle feed cavity to flow past for injection from orifices (86) when the needle is unseated from a seat on a tapering surface (82). Fuel is delivered to the needle feed cavity through a slant passage (85) in the nozzle non-parallel to a longitudinal axis (AX) along which the needle is displaced. The orifices are arranged in a hemispherically contoured surface (83) distal to the seat and centered on a point on the longitudinal axis. The orifices have circular transverse cross sections. The axis of each orifice extends radially of the point on the longitudinal axis at an oblique angle to the longitudinal axis.

    Abstract: An engine braking system comprising backpressure valves located in the exhaust system upstream of an engine turbocharger. The valves can be adjustable knife edge flap valves or D-shaped valves situated in each passageway of a divided exhaust manifold. By using backpressure valves located upstream of the turbocharger, the adjustable valves can be closed to varying degrees to generate desired levels of backpressure while allowing exhaust gas to pass though open regions of the partially obstructed flow pathway to reach the engine turbocharger. By not completely closing the valve and not fully restricting the flow of exhaust gas to the turbine, the turbine continues to spin, the engine mass flow is not choked off, and improved brake performance will result.

    Abstract: Torque being produced by a turbocharged internal combustion engine (12) during acceleration under load is calculated by processing (34) a value for actual boost MAP and a value MAP_NOMINAL selected from a map (32) that contains data values for boost that would prevail during steady state engine operation at a respective speed with the engine developing a respective torque. The selection is made using engine speed N and estimated torque TQI_SP that possesses some inaccuracy due to some disparity between the data value for actual boost and the data value selected from the map. The selection yields a boost disparity value that is used along with the estimated torque to select from a torque map (36) a value for calculated torque that provides a better correlation with actual torque than does the estimated torque during acceleration.

    Abstract: A diesel engine (10) operates by alternative diesel combustion. Formation of fuel and charge air mixtures is controlled by processing a particular set of values for certain input data according to a predictor algorithm model (50) to develop data values for predicted time of auto-ignition θ AI and resulting torque TQ AI , and also develop data values for control of fuel and air that will produce the predicted time of auto-ignition θ AI and resulting torque TQ AI . The data values developed by the predictor algorithm and data values for at least some of the input data are processed according to a control algorithm (52) that compensates for any disturbance δIMT, δEGR introduced into any of the data values for at least some of the input data being processed by the control algorithm. This causes the systems to be controlled by compensated data values IVC, M f that produce predicted time θ AI of auto-ignition and resulting torque TQ AI in the presence of any such disturbance δIMT, δEGR.
