Description

연료주입성 개선 및 연료증발가스 저감을 위한 연료탱크의 레벨링 파이프{Leveling pipe of fuel tank}Leveling pipe of fuel tank for improving fuel injection and reducing fuel evaporation gas

본 발명은 연료탱크의 레벨링 파이프에 관한 것으로, 보다 상세하게는 주유후 연료탱크내의 압력해소 시간이 길어져 의해 연료주입구로 연료가 역류되는 것을방지함과 동시에 연료증발가스의 저감을 위해서 연료탱크 내부에 수용되는 레벨링 파이프의 상부측면에 작은 구멍을 형성하는 연료주입성 개선 및 연료증발가스 저감을 위한 연료탱크의 레벨링 파이프에 관한 것이다.The present invention relates to a leveling pipe of a fuel tank, and more particularly, to prevent fuel from flowing back into the fuel inlet by prolonging the pressure release time in the fuel tank after refueling, and to reduce fuel evaporation gas inside the fuel tank. A leveling pipe of a fuel tank for improving fuel injection and reducing fuel evaporation gas to form a small hole in the upper side of the leveling pipe to be received.

자동차의 연료탱크는 엔진구동에 소모되는 연료를 저장하는 용기로서, 종래의 자동차용 연료탱크는 도3에 도시된 바와 같이, 얇은 강판으로 형성되는 연료탱크(10)의 일측으로 연료를 보충하기 위한 연료주입관(12)이 형성되고, 상기 연료주입관(12)의 일측으로는 연료주입시 연료탱크(10)에 연료가 과주입되는 것을 방지하기 위한 레벨링 파이프(14)가 형성된다.A fuel tank of an automobile is a container for storing fuel consumed for driving an engine, and a conventional automotive fuel tank is for replenishing fuel to one side of a fuel tank 10 formed of a thin steel plate, as shown in FIG. 3. A fuel injection pipe 12 is formed, and one side of the fuel injection pipe 12 is formed with a leveling pipe 14 for preventing fuel from being excessively injected into the fuel tank 10 during fuel injection.

상기한 연료주입관(12)의 상단에는 연료를 주입하기 위한 주유구(16)가 형성되고, 그 도중에는 연료가 상기 주입구(16) 측으로 역류되는 것을 방지하기 위한 셧오프밸브(Shut-off valve,18)가 형성된다.An injection port 16 for injecting fuel is formed at an upper end of the fuel injection pipe 12, and a shut-off valve 18 prevents the fuel from flowing back to the injection port 16. ) Is formed.

그리고 연료탱크(19) 내에서 발생되는 연료증발가스를 포집하여 증발가스가 대기중으로 방출되는 것을 방지하기 위한 캐니스터(20)가 형성되는데, 이 캐니스터(20)와 연료탱크(10)를 연결하는 연결관(22)의 도중에는 2웨이밸브(2Way valve,24)가 형성되고, 연료탱크(10)에 연결되는 상기 연결관(22)의 끝단에는 컷밸브(Cut valve,26)가 형성된다.In addition, a canister 20 is formed to capture fuel evaporation gas generated in the fuel tank 19 and prevent evaporated gas from being released into the atmosphere. The connection connecting the canister 20 and the fuel tank 10 is performed. A 2-way valve 24 is formed in the middle of the pipe 22, and a cut valve 26 is formed at the end of the connecting pipe 22 connected to the fuel tank 10.

상기와 같이 구성되는 연료탱크(10)에 연료를 주입하는 과정을 간단하게 설명하면 다음과 같다.The process of injecting fuel into the fuel tank 10 configured as described above is briefly described as follows.

상기한 연료탱크(10)에 연료가 일정량 이상 주입되면 연료의 유면이 상승됨에 따라서 상기한 레벨링 파이프(14)의 개방구가 연료에 의해 막히게 된다. 이 때연료탱크(10) 내의 압력상승에 의해서 주입되는 연료가 역류하여 주입건(30)을 정지시키게 된다. 이 때, 셧오프밸브(18)가 주입구 측을 막게되고, 연료탱크(10) 내의 압력은 2웨이밸브(24)를 통해서 압력이 해소되며, 일정시간이 경과하게 되면 연료탱크(10) 내의 압력은 정상상태에 이르게 된다.When the fuel is injected into the fuel tank 10 in a predetermined amount or more, as the oil level of the fuel is raised, the opening of the leveling pipe 14 is blocked by the fuel. At this time, the fuel injected by the pressure rise in the fuel tank 10 flows backward to stop the injection gun 30. At this time, the shut-off valve 18 blocks the inlet side, the pressure in the fuel tank 10 is released through the two-way valve 24, the pressure in the fuel tank 10 when a certain time elapses Will reach a steady state.

특히, 상기한 2웨이밸브(24)는 연료주입시 연료탱크(10) 내의 압력을 해소하는 역할 뿐만이 아니라, 연료탱크(10) 내의 연료증발가스 발생을 억제하는 역할을 한다. 그런데 상기 2웨이밸브(24)의 구멍 직경은 보통 0.5 ~ 2.0 mm이며, 그 직경이 커질 수록 연료증발가스의 발생량은 증가하게 된다.In particular, the two-way valve 24 serves not only to relieve the pressure in the fuel tank 10 during fuel injection, but also to suppress the generation of fuel evaporation gas in the fuel tank 10. By the way, the hole diameter of the two-way valve 24 is usually 0.5 ~ 2.0 mm, the larger the diameter of the generation of fuel evaporation gas increases.

즉, 상기 연결관(22)의 도중에 형성된 투웨이 밸브(24)는 연료탱크 안이 정압이 되었을 때에는 탱크내의 연료증발가스를 캐니스터(20)로 보내어 가스를 포집하여 엔진으로 보내게 되고, 부압이 되었을 경우에는 캐니스터에서 신선한 공기가 흡입되게 하여 탱크내의 부압이 정압으로 환원하게 한다.That is, the two-way valve 24 formed in the middle of the connecting pipe 22 sends the fuel evaporation gas in the tank to the canister 20 when the pressure inside the fuel tank becomes positive pressure, collects the gas, and sends the gas to the engine. The fresh air is sucked into the canister so that the negative pressure in the tank is reduced to the positive pressure.

그러나, 연료주입 후에 연료탱크 내의 압력해소 시간이 길어지게 되면 셧오프밸브의 기밀 부위를 통해서 연료가 역류되어 주입구에서 연료가 흘러넘치게 되는 문제점이 있었으며, 압력해소 시간을 빠르게 하기 위해 2웨이밸브의 구멍 직경을 크게 하면 연료가 역류되는 것은 방지되지만 상용시(차량의 주행 및 정차시)에 연료증발가스의 발생이 많아져 배기가스(Emission) 측면에서 불리하게 되므로서 배기가스규제가 심한 지역에서는 캐니스터의 용량을 증대해야만 하는 문제점이 있었다.However, if the pressure relief time in the fuel tank becomes longer after the fuel injection, the fuel flows back through the airtight portion of the shutoff valve, causing the fuel to overflow from the inlet, and in order to speed up the pressure relief time, Increasing the diameter prevents backflow of fuel, but increases the generation of fuel evaporation gas during commercial use (driving and stopping of the vehicle), which is disadvantageous in terms of emission. There was a problem that the capacity must be increased.

따라서 본 발명은 상기한 문제점을 개선하기 위하여 안출된 것으로서, 보다상세하게는 주유후 연료탱크내의 압력해소 시간이 길어져 의해 연료주입구로 연료가 역류되는 것을 방지함과 동시에 연료증발가스의 저감을 위해서 연료탱크 내부에 수용되는 레벨링 파이프의 상부측면에 작은 구멍을 형성하는 연료주입성 개선 및 연료증발가스 저감을 위한 연료탱크의 레벨링 파이프를 제공하는 데 목적이 있다.Therefore, the present invention has been made to solve the above problems, more specifically, the pressure relief time in the fuel tank after the refueling is prolonged to prevent the fuel from flowing back to the fuel inlet and at the same time to reduce the fuel evaporation gas An object of the present invention is to provide a leveling pipe of a fuel tank for improving fuel injection and reducing fuel evaporation gas to form a small hole in an upper side of a leveling pipe accommodated inside a tank.

도 1은 본 발명에 의해 구성된 레벨링 파이프가 장착된 연료탱크의 구성도이며, 도 2는 도1의 "A" 방향에서 바라본 레베링 파이프의 구성도이다.1 is a configuration diagram of a fuel tank equipped with a leveling pipe constructed according to the present invention, and FIG. 2 is a configuration diagram of a levering pipe viewed from the direction "A" of FIG.

도면 중에 표시된 도면부호 10은 연료가 저장되는 연료탱크이며, 도면부호 14는 레벨링 파이프를 지시하는 것으로서, 전체적이 연료탱크(10)의 구성요소가 종래와 같으므로 종래도면에서 사용된 부호를 그대로 사용하여 본 기술을 설명하기로 한다.In the drawing, reference numeral 10 denotes a fuel tank in which fuel is stored, and reference numeral 14 denotes a leveling pipe, and as a whole, components of the fuel tank 10 are the same as in the prior art, and the same reference numerals used in the conventional drawings are used as they are. This technology will be described.

연료탱크(10)에 연료를 보충하기 위해 형성되는 연료주입관(12)의 상단에는주입구(16)가 형성되고, 그 도중에는 셧오프밸브(18)가 형성되는데, 상기한 연료주입관(12)은 일반적으로 지름이 약 15mm정도 되는 금속재의 파이프로 구성된다.An injection port 16 is formed at an upper end of the fuel injection pipe 12 formed to replenish fuel in the fuel tank 10, and a shutoff valve 18 is formed in the middle of the fuel injection pipe 12. Consists of metal pipes, usually about 15 mm in diameter.

그리고 상기한 연료주입관(12)의 일측에는 종래와 같이 레벨링 파이프(14)가 형성되는데, 그 하부 끝단이 연료주입면(F)에 닿을 수 있도록 연료탱크(10)에 수용된다.And a leveling pipe 14 is formed on one side of the fuel injection pipe 12 as in the prior art, the lower end is accommodated in the fuel tank 10 so as to contact the fuel injection surface (F).

상기 연료탱크(10)에 수용되는 레벨링 파이프(14)는 그 끝단으로부터 상측을 향해 약 10~15mm 되는 상부면에 구멍(40)이 형성되는데, 이 구멍(40)의 지름은 0.5~2mm 로 형성하는 것이 바람직하다.The leveling pipe 14 accommodated in the fuel tank 10 has a hole 40 formed in the upper surface of about 10 to 15mm from the end toward the upper side, the diameter of the hole 40 is formed of 0.5 ~ 2mm It is desirable to.

상기한 구멍(40)을 형성하는 이유는 주입구(16)를 통해서 연료탱크(10)에 연료를 주입하게 되면 상기 연료탱크(10) 내의 압력이 상승하게 되는데, 이 압력을 보다 빠르게 해소하기 위한 것이다.The reason for forming the hole 40 is that when the fuel is injected into the fuel tank 10 through the injection hole 16, the pressure in the fuel tank 10 is increased, which is to solve the pressure more quickly. .

그리고 연료탱크(10) 내에 발생되는 연료증발가스를 포집하기 위한 캐니스터(20), 캐니스터(20)와 연료탱크(10)를 연결하는 연결관(22), 연결관(22)의 도중에 형성되어 연료탱크(10) 내의 압력을 해소하기 위한 2웨이밸브(24) 및 컷밸브(26)는 종래와 같이 형성된다.In addition, the canister 20 for collecting fuel evaporation gas generated in the fuel tank 10, the connecting pipe 22 connecting the canister 20 and the fuel tank 10, and the connecting pipe 22 are formed in the middle of the fuel. The two-way valve 24 and the cut valve 26 for releasing the pressure in the tank 10 are formed as in the prior art.

이상과 같이 구성되는 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.

연료건(10)의 노즐부를 주입구(16)에 삽입한 후 연료탱크(10)에 연료를 충전하게 되어 연료탱크(10) 내의 연료가 연료주유면(F)까지 이르게 되면, 주입되는 연료에 의해서 레벨링 파이프(14)의 끝단 개방부가 막히게 된다.When the nozzle of the fuel gun 10 is inserted into the inlet 16, the fuel tank 10 is filled with fuel, and when the fuel in the fuel tank 10 reaches the fuel injection surface F, the fuel is injected. The open end of the leveling pipe 14 is blocked.

이 때, 연료탱크(10) 내의 압력이 상승되므로서 주입연료가 역류하여주입건(30)을 정지시키게 된다.At this time, as the pressure in the fuel tank 10 is increased, the injected fuel flows backward to stop the injection gun 30.

이상과 같이 연료주입이 멈추게 되면 레벨링 파이프(14)의 하부에 형성된 구멍(40)에 의해서 연료탱크(10) 내의 압력은 종래에 비해 빠르게 해소된다.When the fuel injection is stopped as described above, the pressure in the fuel tank 10 is released faster than before by the hole 40 formed in the lower portion of the leveling pipe 14.

따라서 압력해소 시간이 짧아져 주유된 연료가 역류하여 주입구(16) 외측으로 흘러넘치는 것이 방지되며, 보다 신속한 압력조절을 위해 형성되던 투웨이밸브 및 캐니스터의 용량을 확대할 필요가 없게 된다.Therefore, the pressure relief time is shortened to prevent the refueled fuel from flowing back out of the inlet 16, and it is not necessary to enlarge the capacity of the two-way valve and the canister formed for more rapid pressure control.

이상과 같이 구성되는 본 발명은 연료탱크에 연료를 주입한 후 연료가 주입구로 역류하는 것을 방지하기 위해 연료탱크 내부에 수용되는 레벨링 파이프의 도중에 구멍이 형성되므로서 연료 주입후 연료탱크 내의 압력이 빠르게 해소되어 연료주입성이 개선되고, 연료탱크 내의 압력조절을 위해 형성되는 캐니스터를 증대시키지 않아도 되는 장점이 있는 것이다.According to the present invention configured as described above, since the hole is formed in the middle of the leveling pipe accommodated inside the fuel tank to prevent the fuel from flowing back into the injection hole after the fuel is injected into the fuel tank, the pressure in the fuel tank is increased rapidly. There is an advantage that it is eliminated to improve fuel injection, and does not have to increase the canister formed for pressure control in the fuel tank.
