Abstract

본 발명은 기관(engine)의 실화상태를 운전자가 알 수 있도록 하는 장치에 관한 것으로서, 열손실과 열화를 방지하기 위해, 기관의 좌우뱅크에 설치되는 배기관(10)에서 취부되어 배기온도를 감지하는 제1온도센서(21) 및, 제2온도센서(22)와, 상기 배기관(10)이 하나로 연통되는 후단부에 취부되어 배기온도를 감지하는 제3온도센서(23)와, 상기 제1온도센서(21)와 제2온도센서(22)에 통전 가능하게 연결되어 감지신호를 인가받아 평균온도차이를 산출하는 제1연산회로(30)와, 상기 제1연산회로(30)의 출력측과 제3온도센서(23)에 통전 가능하게 연결되어 제1연산회로(30)의 평균온도차이 및 제3온도센서(23)의 감지신호를 인가받아 다시 평균온도차를 산출하는 제2연산회로(40)와, 상기 제2연산회로(40)의 출력측에 연결되어 일정온도 이상의 차이가 되면 실화로 판단하여 경보기(51) 및 표시기(52),(53)에 제어신호를 출력하는 실화판정회로(50)로 구성하는 기관의 실화 판정장치이다.The present invention relates to a device that allows the driver to know the actual condition of the engine (engine), in order to prevent heat loss and deterioration, it is mounted in the exhaust pipe 10 installed in the left and right banks of the engine to sense the exhaust temperature A first temperature sensor 21, a second temperature sensor 22, a third temperature sensor 23 mounted on a rear end portion where the exhaust pipe 10 communicates with one, and detecting an exhaust temperature; and the first temperature A first operation circuit 30 connected to the sensor 21 and the second temperature sensor 22 so as to be energized so as to receive a detection signal to calculate an average temperature difference, and an output side and a first output circuit of the first operation circuit 30. The second operation circuit 40 is connected to the three temperature sensor 23 so as to be energized so as to receive the average temperature difference of the first operation circuit 30 and the detection signal of the third temperature sensor 23 to calculate the average temperature difference again. And connected to the output side of the second operation circuit 40 and judged to be a misfire when a difference is greater than a predetermined temperature. Detectors a misfire judging device of the engine, which consists of 51 and indicators 52, 53, a misfire determining circuit 50 which outputs a control signal to.
