Claims (2)

  1. 엔진의 흡기 통로내에 삽입된 소용돌이 발생체와, 이 소용돌이 발생체의 후방에 발생하는 칼만 소용돌이의 소용돌이 신호를 디지털 량의 전기 신호로서 검출하여, 소정의 주기로서 기억수단에 격납하는 소용돌이 검출 수단과, 상기한 기억수단으로 격납된 소용돌이 검출 수단과, 상기한 기억수단으로 격납된 소용돌이 검출 수단의 출력값을 2값화하여 칼만 소용돌이 펄스를 얻음과 동시에 상기 소용돌이 검출 수단의 출력값이 감소에서 증가로 이행한 후, 소정의 값 이상 증가 하였을 때에 상기 칼만 소용돌이 펄스를 셋트 또는 리셋트하고, 또한 상기 소용돌이 검출 수단의 출력값이 증가에 감소로 이행한 후, 소정의 값 이상 감소하였을 때에 상기 칼만 소용돌이 펄스를 리셋트 또는 셋트하는 2값화 수단을 구비하는 것을 특징으로 하는 엔진의 흡기량 측정 장치.
  2. 제1항에 있어서, 2값화 처리 수단은 미리 프로그램된 순서에 따라서 실행하는 마이크로 프로세서를 구비하고, 그 처리의 실행을 상기 기억수단으로의 격납 타이밍에 동기하여 행하도록 하는 것을 특징으로 하는 엔진의 흡기량 측정장치.
