Abstract

연료 파이프 내의 기포량 감지로써 연료 휘발성을 측정하여 가솔린 엔진의 연소 효율을 최적으로 제어할 수 있는 장치로서, 연료의 기포수를 측정하여 현재 주행 조건에서의 연료증기압을 검출하는 연료증기압 센서와, 상기 연료증기압 센서로부터의 전기 신호를 입력 데이터로 하여 연료의 휘발성을 연산하고 그 연산 결과에 따라 연소 효율이 최적 상태가 될 수 있도록 주행 조건을 제어하는 제어부로 구성되며, 특히 상기의 연료 증기압 센서는 연료 파이프 내의 오리피스와, 상기 오리피스에 의해 발생하는 기포수를 측정하는 포토커플러와, 상기 포토커플러의 검지 결과를 전기신호로써 제어부에 전달하는 회로기판 및 출력단으로 구성되는 가솔린 엔진의 최적 연소 시스템이다.An apparatus for controlling the combustion efficiency of a gasoline engine by measuring fuel volatility by detecting the amount of bubbles in a fuel pipe, comprising: a fuel vapor pressure sensor for measuring the number of bubbles of fuel and detecting a fuel vapor pressure in a current driving condition; And a control unit for calculating the volatility of the fuel using the electric signal from the fuel vapor pressure sensor as input data and controlling the driving condition so that the combustion efficiency is optimized according to the calculation result. A photocoupler for measuring the number of bubbles generated by the orifice in the pipe, and a circuit board and an output terminal for transmitting the detection result of the photocoupler to the control unit as an electric signal.
