Abstract

본 발명은 자동차의 엔진 회전수 감지장치에 관한 것으로서, 벨트가 걸어맞춤되는 제1워터펌프풀리에 형성된 브이홈 외주면에 부착되어 엔진의 회전수를 감지하는 발광센서와, 상기 발광센서 저면 및 제1워터펌프풀리에 일끝이 각각 고정되어밸트의 구속력 해제시 브이홈의 외주면에서 발광센서를 돌출시키는 탄성부재와, 상기 엔진의 케이스 일측에 부착되어 발광센서에 의해 감지된 신호를 입력받는 수광센서와, 상기 수광센서에 연결되어 발광센서에서 감지된 엔진의 회전수를 운전자가 인식할 수 있도록 회전수를 나타내는 제어부를 설치함으로써, 야간 운전시 엔진의 회전수를 운전자가 인식하여 차량속도의 무감각에서 발생되는 대형사고를 미연에 방지할 수 있다.The present invention relates to an apparatus for detecting engine speed of a vehicle, comprising: a light emitting sensor attached to an outer circumferential surface of a v-groove formed on a first water pump pulley to which a belt is engaged; and a light sensor for detecting an engine speed; One end is fixed to each end of the water pump pulley and the elastic member protruding the light emitting sensor from the outer peripheral surface of the V groove when the binding force of the belt is released, and a light receiving sensor attached to one side of the case of the engine to receive the signal detected by the light emitting sensor; The controller is connected to the light receiving sensor so that the driver can recognize the rotational speed of the engine detected by the light emitting sensor so that the driver can recognize the rotational speed of the engine during night driving and is generated from insensitivity of the vehicle speed. Large accidents can be prevented beforehand.
