Abstract

본 발명은 연료탱크내의 불순물 감지장치에 관한 것으로서, 연료탱크에 주입된 연료에서 불순물의 존재여부를 판별하기 위해 연료탱크(T)의 대향면에 각각 설치된 발광소자(1) 및 수광소자(2)와, 속도센서에서 입력된 신호(SR)와 기준신호(Vref)를 비교하여 상기 발광소자(1)에 공급되는 전원(B)를 릴레이(RLY)로 단속하는 비교기(CPI)와, 상기 수광소자(2)에서 감지된 신호를 증폭하는 증폭기(OP)와, 상기 증폭기(OP)에서 입력된 신호와 기준신호(Lref)를 비교하는 비교기(CP2) 및 상기 비교기(CP2)의 출력신호에 의해 온, 오프되는 불순물 경고등(L)으로 구성되는 연료탱크내의 불순물 감지장치를 제공한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an impurity sensing device in a fuel tank, wherein a light emitting device (1) and a light receiving device (2) respectively installed on opposite surfaces of a fuel tank (T) to determine whether impurities exist in fuel injected into the fuel tank. And a comparator CPI for comparing the signal SR input from the speed sensor with the reference signal Vref to control the power B supplied to the light emitting device 1 to the relay RLY, and the light receiving device. On by the amplifier OP for amplifying the signal sensed by (2), the comparator CP2 for comparing the signal input from the amplifier OP and the reference signal Lref, and the output signal of the comparator CP2. The present invention provides an impurity detection device in a fuel tank including an impurity warning light (L) that is turned off.

Description

연료탱크내의 불순물 감지장치.Impurity detection device in fuel tank.

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1A도는 연료탱크에 순수 연료만 주입된 경우 빛의 이동경로를 나타내는 도면1A is a view showing a path of light when only pure fuel is injected into the fuel tank.

제1B는 연료탱크에 불순물이 연료와 혼합 주입된 경우 빛의 이동경로를 나타내는 도면1B is a view showing a path of light when impurities are mixed and injected into a fuel tank

제2도는 본 발명의 개략적인 구성도이다.2 is a schematic configuration diagram of the present invention.
