Abstract

분사노즐(1)의 노즐헤드(2)의 제조에 사용되는 재료는 기계적인 고합금 크롬-니켈강이다. 이러한 강철은 첨가물로서 탄소, 알루미늄, 티탄, 철, 산소, 질소 및 산화이트륨을 함유한다. 디젤엔진과 같은 내연기관의 연소실의 침식성의 화학적 및 열적 환경하에서 분사노즐(1)의 노즐헤드(2)는 종래의 공지된 분사노즐(1)의 노즐헤드(2)에 비하여 유효수명이 대략 2배로 된다.The material used for the manufacture of the nozzle head 2 of the injection nozzle 1 is mechanical high alloy chromium-nickel steel. These steels contain carbon, aluminum, titanium, iron, oxygen, nitrogen and yttrium oxide as additives. Under the erosive chemical and thermal environment of a combustion chamber of an internal combustion engine such as a diesel engine, the nozzle head 2 of the injection nozzle 1 has a service life of approximately 2 compared to the nozzle head 2 of the conventionally known injection nozzle 1. It is doubled.
