Abstract

기관의 냉각수의 상태를 감지하기 위한 냉각수이상감지장치와 오일의 혼입량에 따른 투명도의 변화를 이용하여 냉각수에 대한 오일의 혼입여부를 조기에 감지할 수 있다. 상기 냉각수이상감지장치에서는 상기 발광다이오드(1)와 상기 포토트랜지스터(2)가 기관의 냉각수(8)의 순환계통의 임의의 위치에서 순환관의 한쪽의 벽에 고정된 채로 상기 냉각수(8)에 노출되어 있다. 또한, 상기 발광다이오드(1)와 상기 포토트랜지스터(2)의 사이에는 차광판(4)이 배치되어 있고, 상기 발광다이오드(1)와 상기 포토트랜지스터(2)가 배치된 벽과 반대쪽에 있는 벽에는 반사판(3)이 배치되어 있다. 그리고, 상기 발광다이오드(1)와 상기 수광검출소자(2)와 상기 릴레이(5)와 상기 트랜지스터(6) 및 상기 전원(7)은 도전성 배선에 의해 연결되어 있다. 상기 냉각수이상감지장치는 냉각수(8)가 정상적인 상태일 때에는 출력전류가 거의 없으며, 냉각수(8)의 투명도가 저하되면, 출력전류가 점점 강해진다.The presence of oil in the coolant can be detected early by using the coolant anomaly detection device for detecting the state of the coolant in the engine and the change in transparency depending on the amount of oil in the engine. In the cooling water abnormality detecting device, the light emitting diode 1 and the phototransistor 2 are fixed to one wall of the circulation pipe at an arbitrary position of the circulation system of the cooling water 8 of the engine. Exposed In addition, a light blocking plate 4 is disposed between the light emitting diode 1 and the phototransistor 2, and a wall opposite to the wall where the light emitting diode 1 and the phototransistor 2 are disposed. The reflecting plate 3 is arrange | positioned. The light emitting diode 1, the light receiving detection element 2, the relay 5, the transistor 6, and the power source 7 are connected by conductive wiring. The coolant abnormality detecting device has almost no output current when the coolant 8 is in a normal state, and when the transparency of the coolant 8 decreases, the output current gradually increases.
