Description

다습을 이용한 엔진 흡기 촉진장치Engine Intake Acceleration Device Using Humidity

본 발명은 다습을 이용한 엔진 흡기 촉진장치에 관한 것으로서, 더욱 상세하게는 공기청정기의 여과 엘리먼트 후단에 다습성 부직포를 내재시킴으로서, 흡기의 온도를 저하시키고, 흡기의 중량을 상승시켜, 흡기효율을 향상시키는 엔진 흡기 촉진장치에 관한 것이다.The present invention relates to an engine intake promoting device using high humidity, and more particularly, by embedding a high humidity nonwoven fabric at the rear end of a filtration element of an air cleaner, thereby lowering the temperature of intake and increasing the weight of intake, thereby improving intake efficiency. It relates to an engine intake accelerator.

일반적으로 자동차 엔진에는 연료의 최적연소를 위해 외부로부터의 공기를 공급시키는 흡기장치가 구비되어 있으며, 이는 제1도에 도시되는 바와 같이, 외부 공기에 함유되어 있는 이물질을 여과하기 위한 공기청정기(101)와, 흡입되는 공기량을 측정하기 위한 공기흐름센서(102)와, 흡입공기량을 제어하는 스로틀 보디(103)와, 공기 밸브(104)와, 흡입된 공기를 분배하기 위한 서지 탱크(105)와, 그 분배된 공기를 인젝터로부터 분사되는 연료와 함께 엔진(107)내로 안내하는 흡기매니폴드(106)로 구성되어 있다.In general, an automobile engine is provided with an intake apparatus for supplying air from the outside for optimal combustion of fuel, which is shown in FIG. 1, which is an air cleaner 101 for filtering foreign matter contained in the outside air. ), An air flow sensor 102 for measuring the amount of intake air, a throttle body 103 for controlling the intake air amount, an air valve 104, a surge tank 105 for distributing the intake air, And an intake manifold 106 for guiding the distributed air together with the fuel injected from the injector into the engine 107.

이에 따라, 엔진의 부압에 의해 흡입되는 외부의 흡입공기는 먼저, 공기청정기(101)를 통해 여과되면서 공기흐름센서(102), 스로틀 보디(103), 서지 탱크(105)를 거쳐 흡기 매니폴트(106)의 인젝터로부터 분사되는 연료와 혼합기를 이루면서 거쳐 엔진(107)의 연소실로 흡입되게 된다.Accordingly, the external intake air sucked by the negative pressure of the engine is first filtered through the air cleaner 101, while passing through the air flow sensor 102, the throttle body 103, the surge tank 105, and the intake manifold ( The fuel is injected into the combustion chamber of the engine 107 while forming a mixer with fuel injected from the injector of 106.

그러나, 종래 엔진 흡기장치는 단순히 자연 대기압 상태의 공기를 흡입하여 사용하기 때문에, 건기 운전시, 흡기의 부족으로 비교적 높은 온도 및 중량이 낮은 공기를 흡입하게 된다. 이러한 흡기의 온도 상승 및 중량의 저하는 혼합기의 혼합 효율 및 효율을 저하시켜 엔진의 성능을 저하시킴은 물론 엔진의 소음 발생을 발생시키게 되었다.However, since the conventional engine intake apparatus simply inhales and uses air in a natural atmospheric pressure state, during operation of the dry season, the intake of relatively high temperature and low weight is caused by lack of intake. The increase in temperature and the decrease in weight of the intake air reduce the mixing efficiency and the efficiency of the mixer, thereby lowering the performance of the engine and generating the noise of the engine.

따라서, 본 발명은 상기와 같은 종래의 문제점을 감안하여 안출된 것으로서, 흡기의 온도를 저하시키는 동시에 흡기의 중량을 상승시켜 흡기 효율을 향상시킴으로서, 엔진의 성능을 향상시키는 엔진 흡기 촉진장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described conventional problems, and provides an engine intake acceleration device that improves the performance of the engine by lowering the temperature of the intake air and increasing the weight of the intake air to improve the intake efficiency. The purpose is.

상기와 같은 목적을 달성하기 위하여 본 발명은, 흡기 공기를 여과시키는 공기청정기를 포함하는 엔진 흡기장치에 있어서, 상기 공기청정기의 여과 엘리먼트 후단에 다습성 부직포가 내재되는 엔진 흡기 촉진 장치를 제공한다.In order to achieve the above object, the present invention, in the engine intake apparatus including an air purifier for filtering the intake air, it provides an engine intake acceleration device in which a humid non-woven fabric is embedded in the rear end of the filtration element of the air cleaner.

이하, 본 발명의 실시예를 첨부도면에 의거 더욱 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail based on the accompanying drawings.

본 발명의 실시예에 따른 엔진 흡기 촉진장치는 제2도에 도시되는 바와 같이, 외부로부터의 공기를 케이스(11)로 흡입하기 위한 흡입 덕트(12)와 여과된 공기를 흡기 매니폴드로 공급하기 위한 공급 덕트(13)에 연통되게 연결되는 케이스(11), 상기 흡입 덕트(12)로 흡입되어 공급덕트(13)로 흡입되는 외부 공기를 여과하도록 상기 케이스(11)내에 내장되는 제1여과 엘리먼트(14) 및 제2여과 엘리먼트(14)로 이루어진 공기 청정기(10)와, 다수개의 관통공을 가지며 상기 제1,2여과 엘리먼트(14)(15)를 거쳐 공급 덕트(13)로 흡입되는 공기가 통과되도록 상기 케이스(11)내에 설치되는 다습성 부직포(20)를 포함하는 것을 기술적 구성상의 기본 특징으로 한다. 상기 제1,2여과 엘리먼트(14)(15)는 건식 여과 엘리먼트로 이루어진다.Engine intake accelerator according to an embodiment of the present invention, as shown in Figure 2, to supply the intake duct 12 and the filtered air to the intake manifold for intake air from the outside into the case (11) A case 11 connected in communication with a supply duct 13, a first filtration element embedded in the case 11 to filter external air sucked into the suction duct 12 and sucked into the supply duct 13. An air cleaner (10) consisting of a (14) and a second filtration element (14), and air having a plurality of through holes and sucked into the supply duct (13) via the first and second filtration elements (14,15). It is a basic feature of the technical configuration that includes a humid nonwoven fabric 20 is installed in the case 11 so as to pass. The first and second filtration elements 14, 15 consist of dry filtration elements.

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

엔진의 부압에 의해 흡입 덕트(12)류부터 흡입되는 외부의 공기는 공기 청정기(10)의 케이스(11)는 유입되면서 제1여과 엘리먼트(14) 및 제2여과엘리먼트(15)를 통과하는 먼지 등의 이물질이 걸러져 여과되고, 다습성 부직포(20)를 통과하게 된다. 이때, 다습성 부직포(20)의 관통공을 통과하는 흡입 공기는 다습성 부직포(20)에 내포하고 있는 습기와 결합하게 되므로 습도가 상승하게 된다.The outside air sucked from the intake ducts 12 by the negative pressure of the engine is introduced into the case 11 of the air cleaner 10 and the dust passing through the first filtration element 14 and the second filtration element 15. Foreign substances such as back are filtered to pass through the wet nonwoven fabric 20. At this time, the intake air passing through the through-hole of the high humidity nonwoven fabric 20 is combined with the moisture contained in the high humidity nonwoven fabric 20, the humidity is increased.

이렇게 습도가 상승된 흡입 공기는 공급 덕트(13), 스로틀 보디, 서지 탱크, 흡기 매니폴드 등으로 이루어진 약 1m정도인 흡기계통을 지나면서 습기의 증발, 잠열에 의해 온도가 저하되고, 잠열에 의한 효과로 공기의 중량이 상승하게 된다. 또한, 증발증기에 의해 더욱 상승된 중량으로 엔진의 연소실로 흡입되면서 과급의 효과를 발생하게 된다.In this case, the intake air of which the humidity is increased is passed by the intake pipe, which is about 1 m, made up of the supply duct 13, the throttle body, the surge tank, the intake manifold, and the like. The effect is to increase the weight of the air. In addition, the suction effect is further increased by the evaporative steam as it is sucked into the combustion chamber of the engine.

여기서, 상기 다습성 부직포(20)는 초기 제작시 다량의 물분자를 흡습한 상태로 제조되고 공기청정기(10)의 넓은 확장공간은 유속이 저하되므로 그 통과속도가 일정속도 이상 증가되지는 않아 소모성 부품으로 교환을 하게 되면 된다. 그리고, 그 교환시기를 길게 하기 위한 기술은 갈수록 발전될 수 있다. 또한, 상기 다습성 부직포(20)를 반영구적으로 사용하기 위하여 그 아래에 물탱크를 설치하고, 다습성 부직포(20)와 항상 연결되도록 함으로써 다습성 부직포(20)의 습도를 항상일정하게 유지할 수 있는 방법도 있다.Here, the wet nonwoven fabric 20 is manufactured in the state of absorbing a large amount of water molecules at the time of initial manufacture, and the wide expansion space of the air cleaner 10, the flow rate is lowered so that the passing speed does not increase more than a certain speed is consumable Replace it with parts. And the technology for prolonging the exchange time can be developed more and more. In addition, in order to semi-permanently use the humidified nonwoven fabric 20 by installing a water tank thereon, by being always connected to the humidified nonwoven fabric 20 can maintain a constant humidity of the humidified nonwoven fabric 20 at all times There is also a way.

그리고, 건기의 경우에는 다습성 부직포(20)를 통과한 공기는 습기를 제공받게 되고, 후기의 경우에는 다습성 부직포(20)를 통과한 공기는 그 자체로 다량의 습기를 포함하고 있어 다습성 부직포(20)를 통과하게 되더라도 약간의 습기만을 흡습하게 되기 때문에 결국 건기와 우기 모두에서 다습성 부직포(20)를 통과한 공기는 그 습도가 일정하게 유지되게 된다.And, in the dry season, the air passing through the humidified nonwoven fabric 20 is provided with moisture, and in the latter case, the air passed through the humidified nonwoven fabric 20 itself contains a large amount of moisture. Even though passing through the nonwoven fabric 20 absorbs only a small amount of moisture, the air passing through the humidified nonwoven fabric 20 in both dry and rainy seasons is kept at a constant humidity.

이상에서 살펴본 바와 같이, 본 발명은 과급을 통한 충진 효율을 높여 흡기 효율을 향상시키게 됨으로서, 엔진 성능이 향상됨은 물론 엔진 소음이 저감된다.As described above, the present invention improves the filling efficiency through supercharging to improve the intake efficiency, thereby improving engine performance and reducing engine noise.

본 발명은 특정의 실시예와 관련하여 도시 및 설명하였지만, 첨부 특허 청구범위에 의해 나타난 본 발명의 사상 및 영역으로부터 벗어나지 않는 한도 내에서 다양한 개조 및 변화가 가능하다는 것을 당업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.While the invention has been shown and described with respect to particular embodiments, it will be understood by those skilled in the art that various modifications and changes can be made without departing from the spirit and scope of the invention as indicated by the appended claims. Anyone can grow up easily.
