Abstract: A fuel injector includes an injector housing, an outlet check, an injection control valve assembly, and a valve seat orifice plate integrating a valve seat and various orifices for outlet check control. In the valve seat orifice plate a drain orifice extends between a valve seat surface and a check control chamber formed between a closing hydraulic surface of the outlet check and the valve seat orifice plate. First and second re-pressurization orifices extend between an outer surface of the valve seat orifice plate and the check control chamber.

Abstract: A dual fuel injector in a dual common rail fuel system includes an injector body defining a liquid fuel supply passage to a liquid fuel nozzle outlet, and a gaseous fuel supply passage to a gaseous fuel nozzle outlet. A liquid fuel needle check is movable within the injector body and has an opening hydraulic surface exposed to a fuel pressure of a liquid fuel common rail. A gaseous fuel needle check is positioned side by side with the liquid fuel needle check and has an opening hydraulic surface exposed to the fuel pressure of the liquid fuel common rail. Sensitivity to differences in gaseous fuel rail pressure and liquid fuel rail pressure is reduced by the design.

Abstract: A dual fuel system includes liquid and gaseous fuel supplies and a fuel injector in fluid communication therewith. A gaseous fuel check in the fuel injector forms a leak path with a fuel injector body between gaseous and liquid fuel passages, and a leakage limiting seal is positioned about the gaseous fuel check and deformable into sealing contact with the gaseous fuel check responsive to an increase in a pressure drop from the liquid fuel passage to the gaseous fuel passage in the fuel injector.

Abstract: A fuel system includes a fuel injector having a split check assembly with a control piece, an outlet piece, and a check sleeve. A trapped volume is formed between the control piece and the outlet piece within the check sleeve, to hydraulically couple the control piece to the outlet piece. A starting rate shape clearance fluidly connects the trapped volume to a fuel cavity and is formed between the check sleeve and one of the control piece or outlet piece received therein, and modulates a starting rate shape of fuel injection from the fuel injector. Related methodology is disclosed.

Abstract: The present disclosure is directed to a system for reducing the cold start time for a vehicle with a twin fuel engine. The system has an exhaust system, from which exhaust is discharged and collected on an exhaust manifold. A heat exchanger is positioned within the exhaust system, with coolant flow passages in thermal communication with the engine, and the heat exchanger. A control valve is coupled to a first flow path operable to direct the exhaust through the heat exchanger across the first flow path and a second flow path in selective amounts.

Abstract: A manifold for a pump is configured to connect to a jacket to form a reservoir and to connect to at least one pumping mechanism disposed within the reservoir. The manifold includes a first side including a first side surface configured to face the reservoir and a second side including a second side surface. The manifold also includes a bypass passage, at least one push rod guide bore extending through the first side surface and the second side surface, and a leakage passage fluidly connecting the at least one push rod guide bore to an outlet disposed outside the first side surface. The manifold further includes a discharge passage including at least one inlet disposed in the first side surface, and the at least one inlet is configured to receive fluid pumped by the at least one pumping mechanism.

Abstract: A fuel pump system configured to control a pressure pulse within a fuel system. The fuel pump system includes a conduit and a pump fluidly coupled to the conduit. The conduit has a conduit volume and is configured to contain fuel within. The pump includes a first pump stage in which the pump defines a maximum pump displacement and a second pump stage in which the pump defines a minimum pump displacement. The pump is configured to provide an output mass of fuel to the conduit when the pump transitions from the first pump stage to the second pump stage, causing pressure of the fuel within the conduit to pulse. The maximum pump displacement is set to a value defined by a ratio of the output mass of fuel per the conduit volume needed to maintain the pressure pulse in the conduit within a predetermined pressure pulse range.
