A current change of the motor 508 driving the air pump 500 while increasing the pressure by sending the air to the reference orifice 502 with the inspection valve 504 at the position a, and moving to a fuel system. Is measured in the ECU, and the inspection valve 504 is set to the position b, and air is sent to the fuel gauge through the canister 506 to increase the pressure in the fuel tank 510, thereby increasing the current change of the motor 508. By measuring at the ECU, by comparing these two measurements, it is determined whether or not the evaporation gas control system is leaking.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 퍼지컨트롤솔레노이드밸브 청소장치의 구성도이고, 도 3은 도 2의 퍼지컨트롤솔레노이드밸브의 상세 구조 및 청소작용을 설명한 도면이다.Figure 2 is a block diagram of a purge control solenoid valve cleaning device according to the present invention, Figure 3 is a view illustrating a detailed structure and the cleaning operation of the purge control solenoid valve of FIG.

본 실시예는 종래의 DMTL의 구성을 이용하여 퍼지컨트롤솔레노이드밸브를 청소하도록 구성하고 있는바, DMTL의 에어펌프(1)로부터 발생된 공기압을 퍼지컨트롤솔레노이드밸브(3)의 필터(5)로 소통시키도록 구비된 청소관로(7)와, 상기 청소관로(7)로 공급된 공기가 상기 퍼지컨트롤솔레노이드밸브(3)의 필터(5)를 통과하여 연료탱크(9)로 보내지도록 구비된 배출관로(11)와, 상기 청소관로(7)를 단속하도록 구비된 밸브수단과, 상기 퍼지컨트롤솔레노이드밸브(3)로부터 DMTL로 향하는 기체의 흐름을 차단하도록 설치된 청소관로체크밸브(13)와, 상기 연료탱크(9)로부터 퍼지컨트롤솔레노이드밸브(3)로 향하는 기체의 흐름을 차단하도록 설치된 배출관로체크밸브(15)를 포함하여 구성된다.The present embodiment is configured to clean the purge control solenoid valve using a conventional DMTL configuration, and communicates the air pressure generated from the air pump 1 of the DMTL to the filter 5 of the purge control solenoid valve 3. And a discharge pipe path provided so that the air supplied to the cleaning pipe path 7 passes through the filter 5 of the purge control solenoid valve 3 and is sent to the fuel tank 9. (11), the valve means provided to control the cleaning pipe (7), the cleaning pipe path check valve 13 provided to block the flow of gas from the purge control solenoid valve 3 to the DMTL, and the fuel And a discharge pipe line check valve 15 installed to block the flow of gas from the tank 9 to the purge control solenoid valve 3.

여기서, 종래의 DMTL 구성요소 중 검사용밸브가 밸브수단으로 대체되었는바, 상기 밸브수단은 DMTL에서 에어펌프(1)로부터 발생된 공기압을 기준오리피스(17)로보내는 연통상태와 직접 캐니스터(19)로 보내는 연통상태 및 상기 청소관로(7)에 공급하는 연통상태를 각각 절환할 수 있도록 형성된 3위치 솔레노이드밸브(21)로 구성하였다.Here, the inspection valve has been replaced by the valve means of the conventional DMTL components, the valve means is in direct communication with the canister (19) to send the air pressure generated from the air pump (1) in the DMTL to the reference orifice (17) It was composed of a three-position solenoid valve 21 formed so as to switch between the communication state to be sent to and the communication state to be supplied to the cleaning pipe (7).

물론, 상기 3위치 솔레노이드밸브(21)는 종래의 검사용밸브와 마찬가지로 엔진을 제어하는 ECU에 연결되어 있고, DMTL에는 상기한 구성 이외에 DMTL로 흡입되는 공기를 여과하는 필터(25)가 별도로 구비되어 있고, 에어펌프(1)를 구동하는 모터(23)도 ECU에 연결되어 제어되도록 되어 있다.Of course, the three-position solenoid valve 21 is connected to the ECU that controls the engine like the conventional inspection valve, DMTL is provided with a filter 25 for filtering the air sucked into the DMTL in addition to the above configuration The motor 23 for driving the air pump 1 is also connected to the ECU and controlled.

The contaminants accumulated in (5) are cleaned to exit to the discharge pipe (11).

공기와 함께 배출관로(11)로 빠져나간 오염물질은 연료탱크(9)로 보내져서연료탱크(9)에 침전되거나 연료필터(5)에 의해 걸러지게 된다.Contaminants exiting the discharge conduit 11 together with the air are sent to the fuel tank 9 to be deposited in the fuel tank 9 or filtered by the fuel filter 5.

따라서, 상기 퍼지컨트롤솔레노이드밸브(3)의 필터(5)는 상기와 같은 청소작용에 의해 오염물질이 제거되어 항상 원활한 작동성을 확보하게 된다.Therefore, the filter 5 of the purge control solenoid valve 3 is to remove the contaminants by the cleaning action as described above to ensure smooth operation at all times.

한편, 상기 배출관로체크밸브(15)는 연료탱크(9)로부터 증발가스가 배출관로(11)를 통해 역류하는 것을 방지하며, 상기 청소관로체크밸브(13)는 캐니스터(19)의 증발가스를 퍼지하는 퍼지컨트롤 작동중 증발가스가 상기 청소관로(7)를 통해 역류하는 것을 방지하도록 하는 역할을 수행한다.On the other hand, the discharge pipe line check valve 15 prevents the backflow of the boil-off gas from the fuel tank (9) through the discharge pipe line 11, the cleaning pipe line check valve 13 to prevent the evaporation gas of the canister (19) It serves to prevent the backflow of the evaporated gas through the cleaning pipe 7 during the purge control operation to purge.

이와 같이 본 발명에 의하면, 종래의 DMTL을 이용하여 퍼지컨트롤솔레노이드밸브의 필터에 축적되는 오염물질을 청소하도록 하여, 필터의 막힘 등에 의한 퍼지컨트롤솔레노이드밸브 작동 불안정의 문제를 해결함으로써, 퍼지컨트롤솔레노이드밸브의 안정적인 작동성을 확보할 수 있도록 한다.As described above, according to the present invention, by purifying the contaminants accumulated in the filter of the purge control solenoid valve using a conventional DMTL, and solves the problem of operation of the purge control solenoid valve due to clogging of the filter, purge control solenoid valve Ensure stable operation of
