Abstract

본 발명은 자동차의 연료분사장치의 공기공급장치에 관한 것으로, 엔진의 연소실(1)쪽으로 뻗은 흡기매니폴드(2)를 관통해서 연료분사인젝터(3)가 경사지게 설치되어 흡기매니폴드(2)를 통해 연소실쪽으로 유입되는 공기에 연료를 분사하여 혼합기를 만들어서 연소실쪽으로 유입시키도록 된 자동차의 연료장치에 있어서, 상기 연료분사인젝터(3)의 연료분출구에 공기주입구가 연통되게 형성되고, 상기 흡기매니폴드(2)와 일체로 연결된 드로를 바디(4)에는 진공흡입구(4a)가 형성되면서 이 진공흡입구(4a)에 의해 흡입된 공기가 상기 연료분사인젝터(3)의 연료분사시에 무화를 촉진시키기 위해 공기주입구로 공급되도록 호스(5)를 매개로 상기 진공흡입구(4a)와 공기 주입구가 일체로 연결된 것을 특징으로 하는 구조로 되어, 분사연료의 무화를 촉진시켜 유독한 배출가스를 줄일수 있게 된다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air supply device for a fuel injection device of an automobile, and passes through an intake manifold (2) extending toward a combustion chamber (1) of an engine so that the fuel injection injector (3) is inclined so that the intake manifold (2) is provided. In a fuel device of a vehicle to inject a fuel to the air flowing into the combustion chamber through the mixture to make the mixer flows into the combustion chamber, the air inlet is formed in communication with the fuel outlet of the fuel injection injector (3), the intake manifold The draw connected to the body (2) integrally with the vacuum inlet (4a) is formed in the body 4, the air sucked by the vacuum inlet (4a) to promote atomization during the fuel injection of the fuel injection injector (3) The vacuum inlet 4a and the air inlet are integrally connected to each other via the hose 5 so as to be supplied to the air inlet, thereby promoting atomization of the injection fuel. It is possible to reduce the emissions.
