Abstract

본 발명은 인젝터를 2개 설치하여 설정된 시간차를 두고 작동시켜 연료를 분사토록 하므로서 연소효율 및 연비의 향상 소음을 저감시키도록 한 차량의 2중연료분사장치에 관한 것으로, 실린더헤드(10)에 설치되어 엔진의 구동력을 전달받아 회전하는 캠샤프트(20)에 일체로 설치되는 주캠(21)및 보조캠(22)과, 캠샤프트(20)의 주캠(21)및 보조캠(22)에 의하여 각각 작동되어 설정된 양의 연료를 1,2차로 나누어 분사노즐(11)로 분사하는 주인젝터(30)및 보조인젝터(40)로 차량의 2중연료분사장치를 구성한다.The present invention relates to a dual fuel injection device for a vehicle to reduce the noise of improving the combustion efficiency and fuel efficiency by operating two injectors to set the time difference to inject fuel, installed in the cylinder head (10) And the main cam 21 and the auxiliary cam 22 integrally installed on the cam shaft 20 that is rotated by receiving the driving force of the engine, and the main cam 21 and the auxiliary cam 22 of the cam shaft 20, respectively. The main fuel injector 30 and the sub-injector 40 which inject the fuel in the first and second amounts of the fuel set by the operation are divided into 1 and 2, thereby forming a double fuel injection device of the vehicle.
