Abstract

본 발명은 가솔린 및 엘피지 겸용 차량의 연료분사 제어방법에 관한 것으로, 보다 상세하게는 가솔린과 LPG(Liquefied Petroleum Gas)의 연료를 모두 사용할 수 있는 엔진을 장착한 차량에 있어, 연료의 전환요구가 발생하면, 각 연료 공급 시스템 및 인젝터(Injector)를 동시에 제어하고, 각 연료의 분사비율 및 분사시간에 기초하여 연료전환이 이루어지도록 한 것이다. 따라서, 안정적이고 효율적인 연료전환이 가능하며, 연료전환중 공연비 이탈로 인한 출력 감소 및 배기가스 증가를 미연에 방지하고, 원활한 연료 전환이 이루어질 수 있는 것이다. 더하여, 연료전환시 발생되는 기계적 스트레스를 최소화하고, 주행하는 운전자에게 안정적인 주행능력을 제공할 수 있다. 따라서, 가솔린과 LPG를 동시에 사용하는 차량에 대한 신뢰성을 향상시킴은 물론, 이종연료를 사용하는 차량에 대한 산업분야에서, 제품의 경쟁력을 향상시키는 효과가 있는 것이다.
