Abstract

Wtryskiwacz paliwa, posiadający korpus (1), element zamykający w postaci iglicy (2) oraz kanałów bezpośredniego podawania paliwa (3), charakteryzujący się tym, że pomiędzy iglicą, a korpusem rozpylacza (4) umieszczony jest dodatkowy element (5) w postaci cienkościennego cylindra. Powierzchnia iglicy (2) oraz dodatkowego elementu (5) posiadają chropowatą, śrubowatą lub fałdowaną powierzchnię. Dodatkowy element (5) może mieć także postać sprężyny, spirali lub porowatej konstrukcji ze spasowanych drutów, czy kulek. Powierzchnia niepracującej części iglicy (2) oraz dodatkowego elementu (5) pokryte są materiałem katalitycznym.A fuel injector with a body (1), a closing element in the form of a needle (2) and channels for direct fuel supply (3), characterized in that an additional element (5) in the form of a thin-walled cylinder. The surface of the needle (2) and the additional element (5) have a rough, helical or corrugated surface. The additional element (5) may also have the form of a spring, a spiral or a porous structure made of matched wires or balls. The surface of the non-working part of the needle (2) and the additional element (5) are covered with catalytic material.
