燃料喷射嘴
摘要：
本发明涉及一种内燃机的燃料喷射嘴（10），具有喷嘴体（11）以及定位在喷嘴体（11）中的喷嘴针（12），其中喷嘴体（11）为用作阀体的喷嘴针（12）如此提供一阀座（13），使得在燃料喷射嘴关闭时，喷嘴针（12）的一区域（15）压靠到由喷嘴体（11）提供的阀座（13）上，并且其中至少喷嘴针（12）的区域（15）由陶瓷材料构成，该区域在燃料喷射嘴关闭时压靠到由喷嘴体（11）提供的阀座（13）上。
摘要（英）：

The invention relates to a fuel injection nozzle (10) of an internal combustion engine. The fuel injection nozzle comprises an injection nozzle body (11) and an injection nozzle needle (12) positioned in the injection nozzle body (11); the injection nozzle body (11) provides a valve seat (13) for the injection nozzle needle (12) working as a valve body; when the fuel injection nozzle is closed, an area (15) of the injection nozzle needle (12) is pressed against the valve seat (13) formed by the injection nozzle body (11); the area (15) of the injection nozzle needle (12) is made from ceramic material; and the when the fuel injection nozzle is closed, the area is pressed against the valve seat (13) formed by the injection nozzle body (11).
