제2도는 본 발명 LPG 차량의 인젝션 연료장치의 개략도.2 is a schematic view of an injection fuel apparatus of the present invention LPG vehicle.

제3도는 공급되는 연료량의 변화도.3 is a variation of the amount of fuel supplied.

Claims (1)

기상, 액상으로된 LPG 연료탱크(1)에서 솔레노이드 밸브겸 필터(2), 프리히터(3), 베이프라이저(4) 및 믹서(5)를 경유 엔진에 연결하고 마이크로 컴퓨터(10)가 보조 솔레노이드 밸브(5')를 경유 믹서 (5)의 공급관에 연결된 LPG차량의 연료 공급 장치에 있어서, 액상 공급관과 솔레노이드 밸브겸 필터(2)사이에 연통하여 별개의 솔레노이드 밸브겸 필터(6), 연료펌프(7)및 인젝터(8)로서 엔진에 연결하고 LPG 연료탱크(1)의 기상 공급관에 압력 레규레이터(9)를 경유인젝터(8)의 공급관에 연통하여 마이크로 컴퓨터(10)를 보조 솔레노이드 밸브(5') 에, 시동스윗치를 경유 연료펌프(7)에, 냉각 수온 스윗치(12)를 경유 전원 및 솔레노이드 밸브겸 필터(2)에 병열된 냉각 수온 스윗치(13)를 경유 전원에 연결하여, 베이프라이저(4)와 믹서(5)사이에 연료차단 솔레노이드 밸브(18)을 삽입 설치하여 이를 전기리레이(ll)을 경유 솔레노이드 밸브겸 필터(6)에 연결함으로서 혹한기 시동시에서 워임업 상태로 진행함에 따른 인젝터 시스템에서 종래의 믹서 시스템으로의 전환시 마이크로컴퓨터(10)가 엔진 시동 꺼짐현상을 방지하기 위한 인젝터(8) 및 믹서(5)를 동시에 구동하고 인젝터(8)는 LPG 연료만을 분사하며 연료차단 솔레노이드 밸브(18)및 믹서(5)의 보조 솔레노이드 밸브(5')는 연료통로 제어수단으로서 연료의 동시공급을 가능케하며 전체 기능을 냉각수 온도 감지 수단인 스윗치(12)(13)로서 절환시킴을 결정할 수 있게함을 특징으로 하는 LPG 차량용 인젝션 연료장치.In the LPG fuel tank (1) in gas phase and liquid phase, the solenoid valve and filter (2), the preheater (3), the vaporizer (4) and the mixer (5) are connected to the diesel engine, and the microcomputer (10) is connected to the auxiliary solenoid. In the LPG vehicle fuel supply device in which the valve 5 'is connected to the supply pipe of the diesel oil mixer 5, the liquid supply pipe and the solenoid valve and the filter 2 communicate with each other to provide a separate solenoid valve and filter 6 and a fuel pump. (7) and as an injector (8), the microcomputer (10) is connected to the engine by connecting the pressure regulator (9) to the gas supply pipe of the LPG fuel tank (1) and the supply pipe of the diesel fuel injector (8) to the auxiliary solenoid valve ( 5 '), the starting switch is connected to the diesel fuel pump 7, the cooling water temperature switch 12 is connected to the diesel power supply and the cooling water temperature switch 13 in parallel with the solenoid valve and filter 2 to the diesel power supply. Between the riser (4) and the mixer (5) a fuel shutoff solenoid valve (18) By inserting and connecting the electric relay (ll) to the solenoid valve and filter (6), the microcomputer (10) is switched from the injector system to the conventional mixer system, which proceeds from the start of the cold weather to the warm-up state. The injector 8 and the mixer 5 are simultaneously driven to prevent engine start-up and the injector 8 injects only LPG fuel and the fuel solenoid valve 18 and the auxiliary solenoid valve 5 'of the mixer 5 ) Is a fuel passage control means that allows the simultaneous supply of fuel and the LPG vehicle injection fuel device, characterized in that it is possible to determine the overall function to switch to the switch (12) (13) as the coolant temperature sensing means. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
