Abstract

본 발명의 목적은 보조공기형식의 인젝터를 구비하는 내연기관에 있어서 보조공기량이 증대해도 연료분사량이 감소하지 않는 연료 분사장치를 제공하는 것이다. 흡기통로(2)를 향한 혼합통로(16)와, 혼합통로(16)를 거쳐서 흡기통로(2)에 연료를 분사하는 인젝터(4)와, 보조공기를 도입하는 보조공기 통로(15)를 구비하는 내연기관의 연료 분사장치에 있어서 보조공기통로(15)와 흡기통로(2)를 맺고 혼합통로(16)에 근사한 압력을 발생하는 근사 압력 발생통로(41)와 근사압력 발생통로 (41)에 발생하는 압력과 인젝터(4)에 공급되는 연료압력의 압력차를 조절하는 압력조절기(29)를 구비한다.It is an object of the present invention to provide a fuel injector in which an amount of auxiliary air does not decrease even when the amount of auxiliary air increases in an internal combustion engine including an injector of an auxiliary air type. A mixing passage 16 facing the intake passage 2, an injector 4 for injecting fuel into the intake passage 2 via the mixing passage 16, and an auxiliary air passage 15 for introducing auxiliary air; In the fuel injector of the internal combustion engine, an auxiliary pressure passage 15 and an intake passage 2 are formed in the approximate pressure generating passage 41 and the approximate pressure generating passage 41 for generating a pressure approximating the mixing passage 16. And a pressure regulator 29 for adjusting the pressure difference between the generated pressure and the fuel pressure supplied to the injector 4.
