The steel fuel conveying pipe is characterized in that a Ni-plate layer is formed on an inner surface of a steel pipe of base material, the Ni-plated layer is wholly composed of a mutual diffusion layer including the base material and Ni and a non-mutual diffusion layer including only Ni formed on an outermost surface of the diffusion layer, a layer thickness of the non-mutual diffusion layer is 3 m or more, and a total layer thickness of the mutual diffusion layer and the non-mutual diffusion layer is 10 m or more and 25 m or less.

The invention relates to a gas metering valve (1) for a dual fuel engine (17), which has a displaceable closing body (6) which, in a position of resting against a valve seat (5), closes the gas metering valve (1) and, in a position of being lifted off from the valve seat (5), opens the gas metering valve (1). The gas metering valve (1) is actuatable in a gas operating mode, in which the gas metering valve (1) meters combustion gas via a gas channel (13) into an intake manifold (15) of the dual fuel engine (17), and in a liquid fuel operating mode, in which the gas metering valve (1) remains sealingly closed against the pressure prevalent in the intake manifold (15). The valve seat (5) is movably situated along a valve seat guide (4), the valve seat (5), owing to the combustion gas pressure in the gas channel (13), in the gas operating mode being pressed away from the closing body (6) against a stop (20) in the gas metering valve (1) and is kept in its operating position, and the valve seat (5) in the liquid fuel operating mode being sealingly pressed by the pressure from the intake manifold (15) against the closing body (6).

An assembly at least comprising a fuel injector for dual fuel operation of an internal combustion engine. The assembly includes a nozzle holder defining a fuel circuit and provided with a nose adapted in use to be in connection with a combustion space of an internal combustion engine, and first and second nozzles in communication with the fuel circuit in the nozzle holder for directly injecting liquid fuel into the combustion space of the internal combustion engine for ignition of a combustible mixture present in the combustion space. The first and second nozzles adjacent to the nose of the nozzle holder are interconnected by a cooling channel. At each actuation of a fuel pump upstream of the first and second nozzles, substantially a full volume of fuel pumped during actuation of the fuel pump is allowed to flow through the cooling channel and via the first and second nozzles.

Various embodiments include a high-pressure fuel pump for a fuel injection system of an internal combustion engine comprising: a rigid housing defining a pressure chamber; a low-pressure region for feeding fuel to the pressure chamber; a sealing element delimiting the low-pressure region in conjunction with the rigid housing, wherein the low-pressure region has a variable volume; wherein the sealing element deflects from a rest position to vary the volume of the low-pressure region and seals off the low-pressure region from surroundings; and a controllable adjusting element operable to deflect the sealing element to control the volume in the low-pressure region.

An injector for injecting fuel, which is introduced from a fuel rail, into an engine to supply the fuel thereto is provided. In particular, the injector includes a housing, an electromagnetic generation unit accommodated in the housing and formed to generate an electromagnetic field when electric power is applied thereto, a core inserted into a fuel-rail-side end of a bobbin to form a magnetic circuit using the generated electromagnetic field, a lead pipe inserted into an engine-side end of the bobbin to form the magnetic circuit by coupling with the core, a molding unit formed to enclose the electromagnetic generation unit and an outer peripheral surface of the core to block introduction of moisture, and a cover coupled to the outer peripheral surface of the core to constitute the magnetic circuit together with the core.

A fuel system cover is provided for an internal combustion engine. The fuel system cover is configured to be mounted on the cylinder head assembly to encapsulate a portion of the fuel system to provide leak prevention, mitigation, and detection capabilities.

A mounting system for injection systems serves to connect a fuel injection valve to a fluid-conveying component. In the installed state, a connector piece of the metering valve is inserted at least partly into a receiving space of a connector body of the component. A support part is disposed on the connector piece. The connector piece of the fuel injection valve is mounted on the connector body in the installed state via the support part, a decoupling element, and a fastening body. The abutment body is retained by the fastening body in such a way that the abutment body is movable radially with respect to the longitudinal axis at least in the context of installation relative to the fastening body.

A fuel injection valve includes a housing with a cavity, a valve needle, an actuator including a magnetic coil arranged in a coil casing, and an armature in the cavity. The housing includes a separation ring positioned between the armature and the coil casing and configured to lead the electromagnetic flux to the armature. The separation ring includes a first part and a second part. The first part is made of a first material and the second part is made of second material that differs from the first material. The first material and the second material are magnetic materials.

A fuel injector assembly including a member and a seat. The member has a first center along a longitudinal axis. The member has a curved surface and a flat surface. The curved surface has a radius of curvature greater than a width of the member. The flat surface is axially opposed to the curved surface. The seat has a second center disposed on the longitudinal axis. The seat is positioned distal from the flat surface defining a flow path in an open position of the fuel injector assembly and is in confronting relation to the flat surface such that the second center is concentric to the first center forming a sealing interface in a closed position of the fuel injector assembly.

A fuel injector assembly includes a valve housing, a valve stem that is disposed in the valve housing, a magnetic coil that surrounds the valve housing and is used to displace the valve stem within the valve housing, and a terminal blade. The terminal blade includes a bus bar that provides an electrical connection between the magnetic coil and an external connector. In addition, the terminal blade includes a clip that is connected to the bus bar at a clip first end and to the valve housing at a clip second end. The clip includes a sacrificial portion that is configured to part, for example by dissolving, when the terminal blade undergoes an overmolding process. As a result of the overmolding process, the clip is separated into multiple, spaced portions.
