Abstract
Description
Claims (1)
- LPG를 연료로 하는 기관의 연료계통이 LPG탱크(1), 여과기(2), 전자밸브(3), 베이퍼라이저(4), 가스혼합기(5) 및 흡기다기관(6)을 통하여 엔진(7)의 각 연소실로 공급되도록 이루어지는 것에 있어서, 상기 베이퍼라이저(4)의 연료출구에서 분기하여 별도의 연료공급라인(8)을 형성하며, 이 연료공급라인(8)을 상기 흡기 다기관(6)에 유입단으로 연결하고, 이 연료공급라인(8)상에 솔레노이드 밸브(9)를 개재하여 상기 연료 공급라인(8)을 개폐하도록 이루되, 상기 솔레노이드 밸브(9)는 저온검출의 온도센서(12)와 기준전압기 비교기(11)에 비교입력되고, 이 비교기 출력이 시동스위치의 스타트 접점과 논리 AND(10)에 입력되어 저온상태와 시동순간의 조건을 만족할때 출력이 발생되어 솔레노이드 밸브가 개방되고 시동이 되거나 저온이 아닐 때 차단되도록 이루어지는 것을 특징으로 하는 LPG엔진의 저온시동성 향상장치.
