Abstract
본 발명은 디젤-수소 엔진의 연료공급장치에 관한 것으로, 디젤엔진의 최초시동시에 엔진이 충분히 가열되지 않은 상태에서는 불완전연소나 일어나 연소실내 국부적인 고온영역이 발생되어 질소산화물의 생성이 증가되거나 HC나 입자상 물질이 배출되는 문제가 있었다.The present invention relates to a fuel supply device for a diesel-hydrogen engine, wherein incomplete combustion occurs when the engine is not fully heated at the time of initial diesel engine, and a local high-temperature region is generated in the combustion chamber, There is a problem that particulate matter is discharged.
본 발명은 예시도면 제2도와 같이, 디젤엔진의 연소실(12)에 경유에 공급하는 경유 인젝터(14)와 수소가스를 공급하는 수소가스 인젝터(16)를 설치하되, 상기 수소가스 인젝터(16)는 수소가스를 압축저장하기 위한 압축수소탱크(18)와, 고압 상태의 수소를 적정한 압력으로 감압시키기 위한 레귤레이터(20)와, 수소가스의 맥동을 흡수하기 위한 어큐뮬레이터(22) 및 실린더의 각 연소실(12)로 수소가스를 유도하는 파이프(24)를 구비한 것이다.The present invention is characterized in that a diesel injector 14 for supplying diesel fuel to the combustion chamber 12 of a diesel engine and a hydrogen gas injector 16 for supplying hydrogen gas are provided, A regulator 20 for reducing the pressure of hydrogen in a high pressure state to an appropriate pressure, an accumulator 22 for absorbing the pulsation of the hydrogen gas, And a pipe (24) for guiding the hydrogen gas to the pipe (12).
따라서 본 발명에 따르면 엔진의 최초 시동시나 저온 시동시에 완전연소를 촉진시키는 수소가스를 혼합분사함으로써 엔진의 연소효율을 증대시킬 수 있으며, 더불어 유해한 배기스를 저감할 수 있는 효과를 얻을 수 있다.Therefore, according to the present invention, it is possible to increase the combustion efficiency of the engine and to reduce the harmful exhaust gas by mixing and injecting the hydrogen gas for accelerating the complete combustion at the initial start of the engine or at the low temperature start.
