나. 발명의 구성 및 작용I. Composition and Function of the Invention
본 발명을 첨부된 도면에 도시된 실시예를 참조하여 하기에 설명한다.The invention is described below with reference to the embodiments shown in the accompanying drawings.
제1도에는 본 발명의 연료조성 검출센서의 구성이 도시되는데, 연료통(1)에는 프리즘(3)이 부착된 반사판(2)이 부착되고 혼합연료가 채워져 있다.1 shows a configuration of a fuel composition detecting sensor of the present invention, in which a reflector 2 with a prism 3 is attached to the fuel container 1 and filled with mixed fuel.
프리즘(3)에는 발광 다이오드(4)로부터 빛이 나와 렌즈(5)를 통하여 평행광으로 입사되고 반사판(2)에 의해서 반사된 빛은 렌즈(6)를 통하여 포지션 센시티브 검출기(Position sensitive detecter)(7)에서 초점이 맺힌다.Light is emitted from the light emitting diode 4 to the prism 3 and is incident as parallel light through the lens 5, and the light reflected by the reflecting plate 2 passes through the lens 6 to a position sensitive detector ( Focus in 7).
본 발명의 연료조성 검출센서의 작동을 설명한다.The operation of the fuel composition detecting sensor of the present invention will be described.
발광 다이오드(4)에서 나온 빛은 렌즈(5)를 통하여 평행광으로 바뀌고 이러한 평행광은 프리즘(3)을 통과하여 연료를 지나게 되며 연료의 조성(가솔린, 가솔린+메탄올)에 따라 굴절율이 다르므로 반사판(2)에서 반사되는 각도가 변하게 된다.The light emitted from the light emitting diode 4 is converted into parallel light through the lens 5, and the parallel light passes through the prism 3 and passes through the fuel. The angle reflected by the reflector 2 is changed.
반사된 평행광은 프리즘(3)과 렌즈(6)를 통하여 포지션 센시티브 검출기(7)의 한점에 모이게 되는데, 이러한 점의 위치로 연료의 조성을 판단한다.Reflected parallel light is collected at one point of the position sensitive detector 7 through the prism 3 and the lens 6, and the position of the point determines the composition of the fuel.
포지션 센시티브 검출기(7)는 검출된 신호를 ECU로 보내고 ECU에서는 연료의 조성이 원하는 값인 지 확인한 후 피드백하여 정확하게 연료의 조성을 얻는다.The position sensitive detector 7 sends the detected signal to the ECU, and the ECU confirms that the composition of the fuel is a desired value and feeds it back to accurately obtain the composition of the fuel.
다. 발명의 효과All. Effects of the Invention
상기와 같이 구성된 본 발명의 연료 조성 검출 센서는 엔진이 요구하는 정확한 연료조성을 만들어서 연료를 공급하여 혼합연료의 가솔린 또는 M85C (가솔린 85%+메탄올 15%)로 운전 가능하여 배기가스의 대폭적인 절감과 대체 연료인 메탄올을 이용 가능하게 해 준다.The fuel composition detection sensor of the present invention configured as described above can be operated with gasoline or M85C (85% gasoline + 15% methanol) of mixed fuel by supplying fuel by making an accurate fuel composition required by the engine, thereby greatly reducing exhaust gas and Methanol, an alternative fuel, is available.

본 발명은 혼합연료를 사용하는 차량에서 실제의 연료 혼합비율을 측정하는 연료조성 검출센서에 관한 것이다.The present invention relates to a fuel composition detection sensor for measuring the actual fuel mixing ratio in a vehicle using a mixed fuel.
혼합연료차량(Flexible Fuel Vehicle)의 경우 연료(가솔린, 메탄올)의 혼합비율을 체적유량으로 제어하여 조정하나 실제의 혼합비율을 측정할 필요가 있다.In the case of flexible fuel vehicles, the mixing ratio of fuels (gasoline, methanol) is controlled by volume flow rate, but the actual mixing ratio needs to be measured.
