Abstract

PURPOSE: To improve fuel atomization by installing to the end of an injector a cap having an air inlet nozzle and an outlet nozzle and by connecting a bottomed receiving bore provided to a fitting member and by introducing the air to a part near a fuel nozzle.
CONSTITUTION: A bottomed cap 13 is fastened to a mounting flange in such a way that it covers a needle holder at the tip of an injector. The cap 13 is provided with a ring-shaped space formed between the cap 13 and the needle holder 4 and is provided with an air inlet nozzle 16 on the side and an air outlet nozzle 17, which matches with a fuel nozzle 5, on the bottom. A bottomed cap receiving hole 19 having an opening 20 which mathes with the fuel nozzle 5 and the air outlet nozzle 17, is installed to an injector mounting member 18 of a suction manifold. The cap 13 is fitted into the receiving hole 19 through ring-shaped seals 26 and 29. With this construction, the air is introduced to a part near the fuel nozzle 5, thereby improving the atomization and fine particles of fuel.
