Abstract

본 발명은 전자 제어를 통하여 실린더측으로 유입되는 연료의 량을 조절하는 방법에 관한 것으로, 보다 더 상세하게는 배기되는 가스에 포함되어 있는 산소 농도의 검출을 통해 연료 압력 레귤레이터의 진공도를 조정하여 실린더 측에 유입되는 연료 량을 이론 공연비로 제어하도록 한 연료 압력 레귤레이터의 압력 조정방법에 관한 것이다.The present invention relates to a method for adjusting the amount of fuel flowing into the cylinder through electronic control, and more particularly, by adjusting the vacuum degree of the fuel pressure regulator by detecting the oxygen concentration contained in the exhaust gas. The pressure control method of the fuel pressure regulator to control the amount of fuel flowing into the theoretical air-fuel ratio.

본 발명은 배기가스로부터 산소의 농도를 검출한 후 운행조건에 따라 설정되는 기준 연소농도와 비교하여, 정상적인 연소가 검출되지 않으면 공급되는 연료량의 과잉 및 결립여부를 연료 압력 레귤레이터에 형성되는 진공도의 듀티가 자동으로 조정되므로 이론 공연비의 연료가 실린더측에 유입되어 정상적인 엔진의 출력으로 승차감을 향상시키고, 불필요한 연료의 소모가 배제되어 운행에 신뢰성이 제공된다.The present invention compares the standard combustion concentration set according to the operating conditions after detecting the concentration of oxygen from the exhaust gas, and if the normal combustion is not detected, the duty of the vacuum degree formed in the fuel pressure regulator to determine whether the fuel amount is excessive Since the fuel is automatically adjusted, the theoretical air-fuel ratio flows into the cylinder to improve ride comfort with the output of a normal engine, and unnecessary fuel consumption is eliminated, thereby providing reliability in operation.
