Abstract

본 발명은 캐니스터내의 활성탄에 증발 가스가 포화되었는지여부에 따라 캐니스터 작동의 정상/비정상 상태를 알 수 있도록 하는 캐니스터 자가진단 장치를 갖춘 차량의 증발 가스 시스템에 관한 것으로 캐니스터내의 활성탄이 포화 상태로 되었을 때 운전자에게 캐니스터의 활성탄이 포화되어 증발 가스가 대기중으로 방출되고 있음을 조기에 진단, 조치하게 함으로서 환경 공해를 줄일 수 있는 효과가 있다.The present invention relates to an evaporative gas system of a vehicle equipped with a canister self-diagnosis device that can determine the normal / abnormal state of the canister operation according to whether or not the activated carbon in the canister is saturated. When the activated carbon in the canister becomes saturated, The operator can reduce the environmental pollution by early diagnosis and action that the activated carbon in the canister is saturated and the evaporative gas is released into the atmosphere.

제3도는 본 발명의 캐니스터 자가 진단장치를 갖춘 증발 가스 시스템의 개략도,3 is a schematic diagram of an evaporative gas system equipped with the canister self-diagnosis apparatus of the present invention,

제4도는 마이크로 스위치에서 엔진 점검등까지의 전기회로 결선 개략도.4 is a schematic diagram of the electric circuit connection from the micro switch to the engine inspection lamp.

Claims (3)

차량의 증발 가스 시스템이 있어서, 캐니스터(3)가 퍼지라인(2) 및 증잘 가스라인(9)을 통하여 엔진(1) 및 연료탱크(8)에 각각 연결되고 ECM(6)와 전기적으로 연결되며, 상기 ECM(6)는 엔진 점검등(7)에 연결되는 것을 특징으로하는 캐니스터 자가진단 장치를 갖춘 차량의 증발 가스 시스템.In the vehicle's evaporative gas system, the canister 3 is connected to the engine 1 and the fuel tank 8 and electrically connected to the ECM 6 via the purge line 2 and the incremental gas line 9, respectively. And the ECM (6) is connected to an engine check lamp (7). 제1항에 있어서, 상기 캐니스터(3)는 활성탄(10)을 내장하고, 상기 활성탄(10)을 지지하는 활성탄 지지판(11), 활성탄 지지판(11) 하단에 설치된 두 개의 활성탄 지지스프링(12), 활성탄 지지스프링(12)사이에 설치된 마이크로 스위치(13), 상기 마이크로 스위치(13)와 ECM(6)와를 전기적으로 연결할 수 있도록 하는 커넥터(5)로 구성되는 것을 특징으로 하는 캐니스터 자가 진단 장치를 갖춘 차량의 증발 가스 시스템.According to claim 1, The canister (3) has a built-in activated carbon 10, activated carbon support plate 11 for supporting the activated carbon 10, two activated carbon support springs 12 installed on the bottom of the activated carbon support plate 11 And a micro switch 13 installed between the activated carbon support springs 12 and a connector 5 for electrically connecting the micro switch 13 to the ECM 6. Equipped with evaporative gas system. 활성탄(10)의 무게 증가분이 소정치에 이를때 캐니스터(3)내의 활성탄지지판(11)이 마이크로 스위치(13)를 온 시켜 NVM(비 휘발성 메모리)에 MAL 동작 코드를 기억시키며 엔진 점검등(7)이 작동되도록 하는 것을 특징으로 하는 캐니스터 자가 진단 장치를 갖춘 차량의 증발 가스 시스템.When the weight increase of the activated carbon 10 reaches a predetermined value, the activated carbon support plate 11 in the canister 3 turns on the micro switch 13 to store the MAL operation code in the NVM (non-volatile memory) and check the engine (7). E) an evaporative gas system of a vehicle with a canister self-diagnosis device. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
