본 발명은 이물질 유입방지용 필터가 장착된 엘피지 연료탱크에 관한 것으로, 더욱 상세하게는 연료의 충전시 연료탱크로 유입되는 연료를 필터링함으로써 이물질의 유입을 차단시켜 엔진의 성능을 향상시킬 수 있는 이물질 유입방지용 필 터가 장착된 엘피지연료탱크에 관한 것이다.The present invention relates to an LLP fuel tank equipped with a filter for preventing the inflow of foreign substances. More specifically, the foreign substance inflow that can improve the performance of the engine by blocking the inflow of foreign substances by filtering the fuel flowing into the fuel tank when the fuel is charged. It relates to an LPG fuel tank equipped with a prevention filter.

일반적으로 자동차의 연료탱크는 연료가 저장되는 탱크와, 상기 탱크의 상부 일측에 주유파이프가 연결되고, 상기 탱크에 근접되는 상기 주유파이프의 일측에는 상기 탱크로 공급된 LPG연료가 주유파이프로 역류되는 것을 방지하도록 셧 오프 밸브가 형성되어 있다.In general, a fuel tank of an automobile includes a tank in which fuel is stored, and an oil supply pipe is connected to an upper side of the tank, and an LPG fuel supplied to the tank is flowed back into the oil supply pipe on one side of the oil supply pipe adjacent to the tank. Shut-off valves are formed to prevent them.

따라서, 상기 주유파이프를 통해 주유건으로부터 투출되는 LPG연료를 공급하여 상기 탱크의 내부에 충전시키게 되는 것이다.Therefore, the LPG fuel discharged from the gas gun through the fuel pipe is to be filled in the tank.

그러나, 종래에는 상기 탱크에 LPG연료를 충전하는 과정에서 고압으로 LPG연료를 압축하는 경우 압축기의 오일이나 충전소의 연료저장탱크 내의 이물질이 LPG연료와 함께 상기 탱크로 유입됨에 따라 이와 같은 이물질이 LPG연료에 혼입되어 엔진으로 공급되면, 연료공급라인에 스케일을 형성하게 되어 연료를 원활하게 공급하지 못하게 되고, 공급되는 연료의 양을 정확하게 감지하지 못하게 되어 제어동작에 에러가 발생하게 되며, 종국에는 엔진의 출력이 급격히 저하되거나 심할 경우 엔진이 꺼지는 현상이 발생하는 등 엔진의 성능을 저하시키는 문제점을 발생시켰다.However, conventionally, when the LPG fuel is compressed at high pressure in the process of filling the tank with LPG fuel, the foreign material in the fuel storage tank of the compressor oil or the filling station flows into the tank together with the LPG fuel, and thus such foreign matter is LPG fuel. When mixed with and supplied to the engine, the scale is formed in the fuel supply line, and the fuel cannot be supplied smoothly, and the amount of fuel supplied cannot be accurately sensed, resulting in an error in the control operation. It caused a problem of degrading the engine performance, such as the engine is turned off when the power is sharply reduced or severely.

더욱이 상기 탱크 내부로 유입된 이물질을 제거하기 위해서는 밸브유닛 중 연료 유입구측에 연결된 밸브를 개방 한 후 세척수로 가압세척하여 이물질을 배출시키고, 석션기를 삽입하여 용기 내부에 잔류하는 이물질을 흡입하여 제거할 수 밖에 없었으며, 이 경우에도 상기 밸브의 협소한 공간을 통해 석션기를 삽입하기가 매우 어려웠을 뿐만 아니라 탱크 내부에서 석션기의 이동이 자유롭지 못하여 탱크 내부의 구석에 잔류하는 이물질을 효과적으로 흡입하지 못하였으며, 이로 인하여 이물질이 LPG연료에 혼입되어 엔진으로 공급될 수 밖에 없었다.Furthermore, in order to remove the foreign substances introduced into the tank, the valve connected to the fuel inlet side of the valve unit is opened, and the foreign substances are discharged by pressurizing with washing water, and the suction unit is inserted to suck and remove the foreign substances remaining in the container. In addition, in this case, it was very difficult to insert the suction device through the narrow space of the valve, and the suction device was not freely moved inside the tank to effectively suck in the foreign substances remaining in the corners of the tank. As a result, foreign matters were mixed with LPG fuel and supplied to the engine.

또한, 상기 탱크 자체를 분리하여 작업할 수 있으나 이 또한 작업과정이 매우 복잡하여 작업시간이 장시간 소요되었을 뿐만 아니라 작업능률이 현저하게 떨어지는 문제점이 있었으며, 상기 탱크에 플랜지 등의 재결합시 기밀을 유지하기 위하여 세밀하게 실링작업을 수행해야 하는 번거로움이 있었다.In addition, it is possible to separate the tank itself, but this work process is also very complicated, not only took a long time working, but also had a problem in that the work efficiency was remarkably decreased.
