The invention relates to a fuel injection valve (1) comprising a valve body (5), in which a pressure chamber (7) is designed which, at one end, is delimited by a conical valve seat (13) to which a blind hole (14) connects. A valve needle (10) is arranged longitudinally displaceably in the pressure chamber (7), a valve sealing face (12) of the needle cooperating with the conical valve seat (13) to control a fuel flow from the pressure chamber (7) to injection openings (15; 115; 215) designed in the valve body (5), wherein a valve needle tip (18) of the valve needle (10) protrudes in the blind hole (14) when the needle is seated against the valve seat (13). The inlet opening (216) of an injection opening (215) is arranged downstream of the valve needle tip (18) in the blind hole (14) and the inlet openings (116) of the remaining injection holes (115) are arranged downstream of the valve needle tip (18) when the valve needle (10) is seated against the valve seat (13). An internal combustion engine comprising such a fuel injection valve (1) and a pencil-type glow plug (35) is designed such the fuel exiting the downstream injection opening (215) forms a pilot injection which is directed to or in the direct vicinity of the pencil-type glow plug (35). Because of the position of this injection opening, fuel is ejected in the direction of the pencil-type glow plug even when the valve needle is offset and even with small needle strokes. |
