A fluid distributor for an injection system, in particular a fuel distributor rail for a fuel injection system for mixture-compressing, spark ignition internal combustion engines. The fuel distributor includes a tubular base body, which is preferably processed by a one-stage or multi-stage forging process, a first high-pressure output, a second high-pressure output, a third high-pressure output, and a fourth high-pressure output being provided at the base body. The second high-pressure output is situated offset by a predefined distance compared to the first high-pressure output in a first direction along a longitudinal axis of the tubular base body. The third high-pressure output is situated offset by the predefined distance compared to the second high-pressure output along the longitudinal axis in the first direction, the fourth high-pressure output being situated offset by the predefined distance compared to the third high-pressure output along the longitudinal axis in the first direction.

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 stern 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.

A multipoint fuel injection system comprises an injection system segment including a circumferentially extending outer support defining a fuel manifold with a plurality of manifold passages extending circumferentially therethrough. A first connector is included at a first circumferential end of the outer support and a second connector is included at a second circumferential end of the outer support opposite the first circumferential end. The first and second connectors are each configured to connect each manifold passage with a manifold passages of a respective outer support of a circumferentially adjacent injection system segment. The system includes a circumferentially extending inner support and a plurality of circumferentially spaced apart feed arms extending radially between the inner support and the outer support. A plurality of outlet openings extend in an axial direction from each feed arm for feeding respective injection nozzles.

A cylinder head assembly includes a cylinder head casting, and an injector sleeve within an injector bore in the cylinder head casting. The injector sleeve includes a first sleeve end, and an injector clamping surface formed by an inner sleeve surface adjacent to a cylindrical second sleeve end. The injector sleeve further includes a sleeve clamping surface in contact with an upward facing middle deck surface of the cylinder head casting, and a reaction wall extending between the injector clamping surface and the sleeve clamping surface to transfer an injector clamping load to the upward facing middle deck surface.

A system of using a flow disc to modify a spray pattern of a fuel injector is a system used to change the spray pattern of injected fuel to increase the air to fuel ratio of an engine. The system includes a flow disc and a fuel injector. The flow disc modifies the spray pattern of the injected fuel by the fuel injector to increase the air contact with the injected fuel. The flow disc includes a disc body and a plurality of spray holes. The disc body is designed to securely fit within the fuel injector. The arrangement of the plurality of spray holes helps modify the spray pattern of the injected fuel. The fuel injector includes an injector body and a spray tip. The injector body controls the flow of the fuel being injected into the engine. The spray tip serves as the outlet of the fuel injector.

A first tubular portion forms a part of a fuel flow passage therein. A first joint surface is formed in one end surface of the first tubular portion. A first inner diameter enlarged portion is formed on a side opposite to the first joint surface. A second tubular portion forms a part of the fuel flow passage therein. A second joint surface is formed in one end surface of the second tubular portion and joined to the first joint surface. A second inner diameter enlarged portion is formed on a side opposite to the second joint surface. A welded portion is formed in an annular shape to extend radially inward from the radially outside of the first joint surface and the second joint surface by welding the first tubular portion and the second tubular portion.

A fuel injector is configured such that a non-magnetic member constituting a magnetic circuit is deformed by an axial force generated when the non-magnetic member is combined with a cover and a housing, thereby providing airtight contact. The fuel injector is a device that injects fuel into an engine by raising a needle. A magnetic field generated from a coil forms a magnetic circuit when the coil is magnetized, and the magnetic circuit raises the needle. The fuel injector includes a block ring disposed inside the coil, a cover disposed at an upper end of the block ring, and a housing disposed at a lower end of the block ring. The block ring is made of a non-magnetic material and configured to extend the magnetic circuit. When the cover and the housing are combined by being screwed together, the upper end and the lower end of the block ring are deformed to provide airtight contact with respect to the cover and the housing, respectively.

An upper housing is provided between a fixed core and a housing opposite to a nozzle hole with respect to a coil. The upper housing is configured to form a magnetic circuit with the fixed core and the housing. The upper housing has a first tapered surface formed on an outer peripheral wall and a first cylindrical surface formed on an inner peripheral wall. The housing has a second tapered surface that radially faces the first tapered surface. The fixed core has a second cylindrical surface that radially faces the first cylindrical surface.

A method of making a fluid injector for a gas turbine engine includes depositing material onto a piece of tube stock. The method includes machining the deposited material into a fluid injector component. Depositing can include laser cladding the material onto the piece of tube stock. The method can include placing or flowing braze into a braze joint location between the deposited material and another fluid injector component and forming the braze into a braze joint in the braze joint location.

An insert device includes a first coupling body inserted into an engine cylinder head. The first coupling body extends around a center axis to define a first interior volume of the first coupling body that is shaped to receive a distal tip of a fuel injector. The insert device includes a second mixing body coupled with the first coupling body and extending around the center axis. The second mixing body includes conduits that receive fuel from the fuel injector and air from a combustion chamber, combine the fuel with the air, and direct the fuel-air mixture into the combustion chamber. The first coupling body has a first end surface positioned to face the cylinder head and the first coupling body is tapered such that an outer diameter of the first coupling body is larger toward the first end surface than toward the second mixing body.
