Abstract

본 발명은 연료분배레일이나 연료공급라인에 압력감지수단을 설치해서 연료압력이 소정치 이하로 떨어질 경우에 인스트루먼트패널상의 엔진검사램프를 점등시킴과 더불어 그에 대응하는 결함코드를 생성할 수 있도록 된 연료시스템의 압력검사장치를 제공한다.According to the present invention, a pressure sensing means is installed on a fuel distribution rail or a fuel supply line to light an engine inspection lamp on an instrument panel when a fuel pressure drops below a predetermined value, and to generate a corresponding defect code. Provide a pressure test system for the system.

이를 위해 본 발명은, 전자제어모듈(40)의 제어에 따라 연료를 엔진으로 공급하는 연료시스템에 있어서, 연료시스템(100)의 연료분배레일(10) 또는 연료공급라인(5)에 장착된 압력감지부(50)와; 이 압력감지부(50)에 의해 감지된 아날로그압력값을 디지탈값으로 변환하는 아날로그/디지탈컨버터(31)와; 이 아날로그/디지탈컨버터(31)로부터 송출되는 입력값과 자체 발생되는 기준값을 비교하여 기준값이 큰 경우에는 인스트루먼트패널부(33)의 “엔진체크램프”을 점등시킴과 동시에 소정의 결함코드를 생성하는 압력처리부(30)를 갖춘 전자에어모듈(40)을 더 구비하여 구성된다.To this end, the present invention, in the fuel system for supplying fuel to the engine under the control of the electronic control module 40, the pressure mounted on the fuel distribution rail 10 or the fuel supply line 5 of the fuel system 100 A sensing unit 50; An analog / digital converter 31 for converting the analog pressure value sensed by the pressure sensing unit 50 into a digital value; When the reference value is large by comparing the input value sent from the analog / digital converter 31 with the reference value generated by itself, the "engine check lamp" of the instrument panel 33 is turned on and a predetermined defect code is generated. It is configured to further include an electronic air module 40 having a pressure processor (30).
