본 발명은 증발가스 흡착구조를 갖는 흡기관에 관한 것으로, 더욱 상세하게는 에어크리너의 연소실측 상측에 공기와 직접 접촉되게 제올라이트흡착층을 형성한 다공 흡착판을 구비하여서 흡기저항을 최소화 하면서 엔진 정지시 발생하는 증발가스를 효율적을 흡착 유지할 수 있도록 함을 목적을 한 것이다.The present invention relates to an intake pipe having an evaporation gas adsorption structure, and more particularly, a porous adsorption plate having a zeolite adsorption layer formed in direct contact with air on the combustion chamber side of an air cleaner to minimize intake resistance when the engine is stopped. The purpose is to be able to efficiently adsorb and maintain the generated evaporated gas.

본 발명의 다른 목적은 알류미늄 다공판에 산화부식층을 형성하여서 코팅 형성되는 제올라이트흡착층의 표면적이 극대화되도록 함을 목적으로 한 것이다.Another object of the present invention is to form an oxide corrosion layer on the aluminum porous plate to maximize the surface area of the zeolite adsorption layer to be formed.

본 발명의 또 다른 목적은 상기 흡착판의 다공 흡착판을 복층으로 구비하되 관통공이 상호 이격되게 형성하여서 공기의 유동이 지그재그 유동되게 하여 흡착효율을 향상시킬 수 있도록 함을 목적으로 한 것이다.Still another object of the present invention is to provide a porous adsorption plate of the adsorption plate in a plurality of layers, but through-holes are formed to be spaced apart from each other so that the flow of air is zigzag to improve the adsorption efficiency.

일반적으로, 자동차에서 발생하는 증발가스는 환경오염을 유발하므로 이를 규제하고 있으며 특히, 연료탱크에서 발생하는 증발가스는 캐니스터를 통하여 흡 착처리함과 더불어 연료탱크의 재질과 형상변경을 통하여 이를 해결하고 있다.In general, the evaporated gas generated from automobiles is regulated because it causes environmental pollution. Especially, the evaporated gas generated from the fuel tank is adsorbed through the canister and resolved by changing the material and shape of the fuel tank. have.

한편, 상기한 바와 같은 연료탱크 이외에도 흡기계통에서도 엔진이 작동 후 정지시 인젝터에 의하여 분사되어서 미처 연소실(31)로 흡입되지 못한 연료와 캐니스터를 통하여 흡기관(32)으로 공급되어서 미처 연소실(31)로 흡입되지 못한 연료가 증발하여서 흡기구를 통하여 대기로 배출되어서 환경오염을 유발시키는 문제점이 있어, 이를 제거하기 위하여 흡기계통에 흡착수단을 구비하여 실시하고 있다.On the other hand, in addition to the fuel tank as described above, in the intake pipe, the combustion chamber 31 is supplied to the intake pipe 32 through the fuel and the canister that is injected by the injector when the engine is stopped after operation and is not sucked into the combustion chamber 31. The fuel that is not sucked into the gas is evaporated and discharged into the atmosphere through the intake port, causing environmental pollution. In order to remove this, the suction pipe is provided with adsorption means.

상기한 바와 같이 엔진이 정지할 때 미처 연소실(31)로 흡입되지 못하고 잔류한 연료가 증발하여 형성된 증발가스를 흡착하는 흡착수단은 에어크리너(34)의 연소실측 상측에 구비되는 활성탄필터(21)로 구성하여 실시하였으나, 상기 활성탄필터(31)의 경우에는 증발가스의 흡착효과는 높으나 흡기저항을 유발시키는 문제점이 있었다.As described above, the adsorption means for adsorbing the evaporated gas which is not sucked into the combustion chamber 31 and the remaining fuel evaporates when the engine stops is activated charcoal filter 21 provided above the combustion chamber side of the air cleaner 34. In the activated carbon filter 31, although the adsorption effect of the boil-off gas is high, there is a problem of causing intake resistance.

또한, 상기 흡착수단의 다른 실시예로 에어크리너박스(24)의 벽면에 제올라이트 코팅 형성한 제올라이트코팅층(22)을 형성하여 실시하였으나, 상기 제올라이트코팅층(32)의 경우에는 흡기저항이 발생하지 않아 효율적이나 경량화를 위하여 플라스틱을 형성한 에어크리너박스(33)를 제올라이트의 코팅이 가능한 알류미늄으로 형성하여야 하므로 그 원가가 상승되고 벽면에서 흡착이 이루어지므로 흡착효율이 저하되는 문제점이 있었다.In addition, the zeolite coating layer 22 having a zeolite coating formed on the wall surface of the air cleaner box 24 was formed as another embodiment of the adsorption means. However, in the case of the zeolite coating layer 32, the intake resistance does not occur. In order to reduce the weight, the air cleaner box 33 formed of plastic must be formed of aluminum which can be coated with zeolite, so that the cost is increased and adsorption is performed on the wall, thereby reducing the adsorption efficiency.

또한, 상기 흡착수단의 또 다른 실시예로 흡기관(32)에 활성탄 또는 제올라이트가 코팅퇸 하니콤흡착구(23)로 구성하여 실시하였으나, 상기 흡착제로 활성탄이 사용된 경우에는 흡착효율은 높으나 흡기저항을 유발시킴과 더불어 코팅된 활성 탄이 쉽게 이탈되며, 제올라이트를 코팅 형성한 경우에는 그 원가가 고가로 형성되는 등의 문제점이 있었다.In addition, as another embodiment of the adsorption means, the intake pipe 32 is coated with activated carbon or zeolite, and the honeycomb adsorption port 23 is used. However, when activated carbon is used as the adsorbent, the adsorption efficiency is high but In addition to causing resistance, the coated activated carbon is easily released, and when the coating is formed of zeolite, there is a problem that the cost is formed at a high price.

이에, 본 발명은 상술한 바와 같이 종래의 흡착수단이 가진 구조적, 효율적, 원가적 문제점을 해결하여 흡착효율을 높임과 더불어 흡기저항을 유발시키지 않도록 한 것이다.Accordingly, the present invention solves the structural, efficient, and costly problems of the conventional adsorption means as described above, thereby increasing the adsorption efficiency and not causing the intake resistance.

즉, 본 발명은 에어크리너의 연소실측에 공기와 직접 접촉되게 제올라이트흡착층을 형성한 다공 흡착판을 구비한 것이다.That is, the present invention includes a porous adsorption plate in which a zeolite adsorption layer is formed on the combustion chamber side of the air cleaner to be in direct contact with air.

따라서, 본 발명은 표면에 제올라이트흡착층이 형성된 다공 흡착판을 구비하므로서 엔진의 정상 작동과정에 있어서는 충분한 통기성을 유지하여 흡기저항을 최소화 하며 엔진의 정지시는 미처 연소실로 공급되지 못한 연료가 증발하여 발생한 증발가스가 효율적으로 흡착 유지되는 것이다.
Therefore, the present invention has a porous adsorption plate having a zeolite adsorption layer formed on its surface, thereby maintaining sufficient air permeability in the normal operation of the engine to minimize intake resistance. Evaporated gas is efficiently adsorbed and maintained.

이하, 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

The fuel of the intake system, which is not supplied to the combustion chamber, evaporates to the atmosphere through the intake port. In the case of adsorbing means capable of adsorbing and maintaining the discharged evaporated gas, the air cleaner 34 on the intake tube has a porous adsorption plate 10 having a zeolite adsorption layer 11 formed in direct contact with air. will be.

여기서, 상기 다공 흡착판(10)은 강성을 유지할 수 있게 0.3~0.6mm의 알류미늄판에 다수의 통기공(10a)을 관통 형성한 후 표면에 제올라이트를 코팅하여 350~450℃의 온도로 소성가공하여 제올라이트흡착층(11)을 형성하는 것이다.Here, the porous adsorption plate 10 is formed through a plurality of vent holes (10a) in an aluminum plate of 0.3 ~ 0.6mm to maintain rigidity, and then coated with zeolite on the surface to be plastically processed at a temperature of 350 ~ 450 ℃ The zeolite adsorption layer 11 is formed.

한편, 본 발명의 다른 실시예로는 알류미늄 다공판에 코팅 형성되는 제올라이트흡착층(11)의 표면적이 극대화될 수 있게 상기 제올라이트흡착층(11)의 코팅이전에 약산 또는 염기성의 산화액을 도포하여 산화 부식시킨 산화부식층(12)을 형성하여 실시함이 바람직한 것이다.On the other hand, in another embodiment of the present invention by applying a weak acid or basic oxidizing solution before the coating of the zeolite adsorption layer 11 to maximize the surface area of the zeolite adsorption layer 11 is formed on the aluminum porous plate It is preferable to form and carry out the oxidation corrosion corrosion layer 12 which oxidized and corroded.

또한, 본 발명의 다른 또 다른 실시예로는 공기가 지그재그 유동되어서 공기가 제올라이트흡착층(11)과 고르게 접하도록 상기 다공 흡착판(10)을 복층으로 구비하되 통기공(10a)이 상호 이격되게 구비하여 실시함이 바람직한 것이다.In another embodiment of the present invention, the porous adsorption plate 10 is provided in multiple layers so that the air is zigzag-flowed so that the air is in contact with the zeolite adsorption layer 11, but the vent holes 10a are spaced apart from each other. It is preferable to carry out.

이하, 본 발명의 제조과정 및 그 작용에 대하여 설명하면 다음과 같다.Hereinafter, the manufacturing process and the operation of the present invention will be described.

상기한 바와 같이 연소실로 미처 공급되지 못하고 흡기계통에 잔류한 연료가 증발하여서 흡기구를 통하여 대기중으로 배출되는 증발가스를 흡착 유지할 수 있게 한 흡착수단을 구비함에 있어서, 흡기계통 상의 에어크리너(34) 연소실측에 공기와 직접 접촉되게 제올라이트흡착층(11)을 형성한 본 발명의 다공 흡착판(10)은 0.4mm 이하로 그 강성이 유지되는 알류미늄 판재에 다수의 통기공(10a)을 관통 형성한다.As described above, when the fuel remaining in the intake cylinder cannot be supplied to the combustion chamber and the fuel remaining in the intake cylinder evaporates to adsorb and hold the evaporated gas discharged into the atmosphere through the inlet, the air cleaner 34 on the intake cylinder is burned. The porous adsorption plate 10 of the present invention in which the zeolite adsorption layer 11 is formed to be in direct contact with air on the actual side is formed with a plurality of vent holes 10a penetrating through an aluminum plate whose rigidity is maintained at 0.4 mm or less.

이상과 같이 통기공(10a)이 관통 형성된 알류이늄 판재의 표면에 약산 또는 염기성 산화액을 도포하여 표면을 부식시키고 이를 200~400℃ 온도의 산화분위기에서 1 시간 정도 노출시켜 산화부식층(12)을 형성한다.As described above, a weak acid or basic oxide solution is applied to the surface of the aluminum plate through which the air hole 10a is formed to corrode the surface, and the oxide corrosion layer 12 is exposed by exposing it for about 1 hour in an oxidizing atmosphere at a temperature of 200 to 400 ° C. Form.

그리고, 상기 산화부식층(12)에 제올라이트를 코팅한 후 약 400℃의 온도에서 3시간 동안 소성가공하여 제올라이트흡착층(11)이 형성되게 하여 제조하는 것이다.After the zeolite is coated on the oxidized corrosion layer 12, plastic processing is performed at a temperature of about 400 ° C. for 3 hours to form the zeolite adsorption layer 11.
