Abstract: The invention relates to a fuel injection valve, comprising a valve seat body (16) with a fixed valve seat surface (29). A valve closing body cooperates with the valve seat (29) in order to open and close said valve. The valve seat body (16) has an external covering surface (44). Said surface is provided with a coating (45) which is made of a different material to that of the valve seat body (16) or provided with an adhesive which is used to create a hydraulically sealed connection between the valve seat body (16) and a valve seat carrier (1) which receives said valve seat body (16). The fuel injection device is particularly suitable for use in fuel injection systems of mixture-compressing spark-ignition internal combustion engines.

Abstract: The invention concerns an injector comprising a nozzle pierced with at least one fuel outlet orifice (7) towards an engine combustion chamber. A ceramic coating (14) is deposited on the nozzle outer surface, preferably in a break (12) defining a recess in said outer surface, at least around and immediately downstream of the outlet orifice (7), relative to the fuel passage direction. The invention is applicable to fuel injectors with anti-scale ceramic coating for internal combustion engines with controlled ignition and direct injection.

Abstract: In existing valves with a spherical valve closing body and a spherical valve seat surface, the valve closing body is located in a contact circle on the valve seat surface. One possible danger is that the valve closing body no longer seals the valve seat surface after a given operating time of the valve, thereby causing the fluid leakage. The inventive valve seeks to improve the sealing capability of the valve. A recess (40) in the valve seat surface (29) forms a first circular edge (41) and a second circular edge (42). When the valve is closed, the spherical closing body (7) is placed on both circular edges (41, 42), thereby improving the sealing ability of the valve. The inventive valve is particularly useful in fuel injection valves for externally ignited mixture compressing internal combustion engines.

Abstract: Multiple stacked orifice disk members (26a, 26b) cooperatively form a chamber space (46) through which fuel is constrained to pass as it flows from the valve seat (20) to the nozzle (16). Orifices (48) in one member that communicate the chamber space to the fuel flow are larger and perform primarily a turbulent flow creating function while orifices in another member (50) that communicate the chamber space to the fuel flow are smaller and perform primarily a metering and targeting function. Thus, turbulence and metering functions are segregated from each other. In certain embodiments at least one more orifice disk member is sandwiched between the first two to divide the chamber space in one or more smaller chamber portions while still providing fluid communication between such portions, such added disk member(s) contributing either one or both functions of turbulence or better metering and targeting. In certain embodiments, all orifices are equal so that each contributes to turbulence, metering, and targeting.

Abstract: Fuel injection valve which serves for injecting fuel into the admission passage of a mixture-compressing, externally-ignited internal combustion engine. The fuel injection valve is provided with a valve needle (27) which, by means of an armature linked therewith, is drawn against a core when a magnetic coil is excited, the valve needle (27) rising, together with a sealing seating (47) formed thereon, from a valve seating surface (48) formed on a nozzle body (9). The sealing seating (47) is designed with a rounded profile (90), the contour of which follows the external envelope of an imaginary torus (94). The cross-section of the torus (94) can for example, be circular (93) or elliptical (96). In view of the comparatively small radius of the rounded profile (90), which leads to a distinctly line-like contact between the valve needle (27) and the valve seating surface (48), the tendency of the valve needle (27) to ''adhere'' hydraulically to the valve seating surface (48) is much smaller than in conventional fuel injection valves.

Abstract: Systems and methods are provided for operation of fuel injectors within an applied-ignition, direct-injection internal combustion engine. In one example, a needle of a fuel injector is moved from a retracted position to an extended position relative to a plurality of injection holes of a nozzle of the fuel injector, with at least one injection hole being separated from a fuel supply system earlier than each other injection hole. In a partially retracted position, fuel flow along a first side of the needle is decreased relative to fuel flow along a second side of the needle.
