A fuel injector and a nozzle for a fuel injector is provided. The nozzle includes at least one spray hole that is formed through a hardened nozzle body. The nozzle body is hardened again after forming the at least one spray hole to hardened the nozzle body...

The injection nozzle has an inner contour with a pre-chamber (14) that opens at an end into a spray chamber with an inlet opening (13). A cylindrical guide channel (17) that is connected to another end of the pre-chamber communicates with outside of a body...

The disclosure relates to a fuel injection valve. The fuel injection valve for an internal combustion engine includes a needle which moves within a valve housing; a valve seat formed therein with an opening and closing hole which is opened and closed by th...

The valve has a valve body (4) with a recess in which a valve needle (6) is movable in an axial direction. The needle together with the body forms an injection nozzle in a downstream zone. The needle in a closed position prevents a fuel from passing throug...

A fuel injector which, under the control of the engine ECM, controls the fuel injection event profile by means of a shuttle valve of the injector. The shuttle valve is constructed so that axial forces generated by fuel pressure are balanced. In a preferred...

A fuel injector comprises a fuel flow passage about a central axis (2) of the fuel injector, the passage including a valve seat (3) inclined at a first angle to the central axis; and a needle orifice (6); wherein the passage further comprises a first volum...

An injection nozzle for use in delivering fuel to a combustion space includes a valve member in the form of a valve needle (18) which is slidable within a bore (11) and engageable with a seating (12A) to control fuel flow through an outlet opening (25A, 25...

The injection port bearer body (5a) has one or more injection ports (7) and is housed in the valve seat body (5) and made of material with lower thermoconductivity coefficient than the valve seat. The port bearer (5a) has thermoconductivity of less than 2 ...

An injection nozzle for use in delivering fuel to a combustion space comprises a nozzle body (25) provided with a blind bore within which a valve member (20) is slidable. The valve member (20) comprises a first region (20a) of substantially frusto-conical ...
