Description
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.
본 고안은 자동차의 공기청정기및 흡입유로에 관한 것으로서, 특히 공기청정기에 연통되어 외부공기를 흡입하는 덕트의 구조를 개선하여 중저속 운전시 흡입소음이 저감되도록 하고, 고속시 흡입공기량이 증대되도록 하는 자동차의 공기청정기및 덕트구조에 관한 것이다.The present invention relates to an air purifier and a suction flow path of an automobile, and in particular, to improve the structure of the duct connected to the air cleaner to suck external air to reduce the suction noise during low and medium speed operation, and to increase the amount of intake air at high speed. It relates to the air purifier and duct structure of a vehicle.
일반적으로, 자동차의 선단부는 기관이 설치되는 기관실이 형성되고, 기관실 상부에 본네트(bonnet)가 개폐 가능하게 덮여지어, 기관실 내에서 기관의 상부에 기관의 연소실과 연통되는 공기청정기(air cleaner)가 설치되며, 상기 공기청정기에 연통되는 흡입덕트(air duct)가 기관실 내부에 장착되어 있다.In general, the front end of the vehicle is formed with an engine room in which an engine is installed, and a bonnet is covered to be openable and closed in an upper part of the engine room. It is installed, the air duct (air duct) in communication with the air cleaner is mounted inside the engine room.
이와같이 구성되는 자동차는 기관이 작동되면 흡입행정시 연소실에 형성되는 부압이 공기청정기 및 흡입덕트에 작용되어 외부의 공기가 흡기덕트를 통해 공기청정기로 유입되고, 공기청정기 내부에서 필터에 의해 여과된 후 기관의 연소실로 흡입되며, 연소실로 유입된 흡입공기가 연료공급장치로부터 공급된 연료와 함께 연소되도록 되어 있다.When the engine is operated, the negative pressure generated in the combustion chamber during the intake stroke is applied to the air cleaner and the suction duct so that the outside air flows into the air cleaner through the intake duct, and is filtered by the filter inside the air cleaner. It is sucked into the combustion chamber of an engine, and the suction air which flowed into the combustion chamber is combusted with the fuel supplied from the fuel supply apparatus.
그러나 이러한 종래 자동차는 기관의 작동중 외부공기를 흡입하는 과정에서 흡입력에 의해 흡기소음이 발생되는데, 흡입덕트의 길이를 1200mm로 설정하면 흡기소음을 충분히 저감시킬 수 있으나, 기관실의 레이아웃상의 문제로 500-800mm로 다소 짧게 설정하기 때문에 소음이 다소 크며, 흡입덕트를 너무길게 형성하는 경우 소음이 저감되지만 이경우 고속시 흡입공기량이 불충분하게 되는 문제점이 있었다.However, such a conventional car generates intake noise due to the suction force in the process of inhaling external air during operation of the engine.If the length of the intake duct is set to 1200 mm, the intake noise can be sufficiently reduced. The noise is rather large because it is set slightly shorter at -800mm, and the noise is reduced when the suction duct is formed too long, but in this case, there is a problem that the amount of suction air is insufficient at high speed.
본 고안은 상기 종래와 같은 문제점을 보완하기 위해, 고속회전시 개구되도록 하는 고속흡기통로가 별도로 형성되고, 흡기덕트의 전체길이가 일정길이 연장되도록 하여, 중저속시 흡기소음이 효과적으로 저감되도록 하고, 고속시 2개의 통로를 통해 공기에 공기를 흡입하도록 하여 흡입효율이 향상되도록 하는데 그 목적이 있다.The present invention, in order to supplement the problems as described above, the high-speed intake passage to be opened at high speed rotation is formed separately, so that the entire length of the intake duct extends a certain length, to effectively reduce the intake noise at low and medium speeds, The purpose is to inhale air into the air through the two passages at high speed to improve the suction efficiency.

본 고안은 제1도와 제2도에 도시되는 바와 같이, 흡입공기중의 먼지를 여과하는 엘리먼트(20)가 착탈 가능하게 장착되는 공기청정기(10)의 일측부에 외측면부를 따라 절곡 연장되는 공기통로(13)가 내부와 연통되게 형성되고, 공기청정기(10)의 타측면에 고속흡기통로(11)가 형성되어, 공기통로(13)의 끝에 흡기덕트(14)가 연통되게 연결되고, 나비밸브(15)가 개폐 가능하게 장착되는 고속흡기덕트(12)가 고속흡기통로(11)에 연통되게 연결됨을 그 기술적 구성상의 기본 특징으로 한다.The present invention, as shown in FIG. 1 and FIG. 2, the air cylinder which is bent and extended along the outer surface portion on one side of the air cleaner 10, which is detachably mounted to the element 20 for filtering dust in the intake air. The furnace 13 is formed in communication with the inside, the high speed intake passage 11 is formed on the other side of the air cleaner 10, the intake duct 14 is connected to the end of the air passage 13 in communication, the butterfly The high speed intake duct 12 in which the valve 15 is mounted to be openable and closed is connected to the high speed intake passage 11 in a basic feature thereof.
여기에서, 나비밸브(15)는 고속흡기덕트(12)의 외측 끝단부 내부에 회동 가능하게 지지되고 액츄에이터(50)에 의해 회전구동이 가능하게 장치되며, 액츄에이터(50)가 기관(30) 회전속도의 감지신호를 입력받아 일정회전수 이상에서 제어신호를 출력하는 전자제어장치(40)에 의해 제어 가능하게 연결된다.Here, the butterfly valve 15 is rotatably supported inside the outer end of the high speed intake duct 12 and is rotatably driven by the actuator 50, and the actuator 50 rotates the engine 30. The control signal is connected to the electronic control device 40 that receives the detection signal of the speed and outputs the control signal at a predetermined rotation speed or more.
이와같이 구성되는 본 고안은, 기관(30)이 작동되면 기관(30)의 시간당 회전수가 전자제어장치(40)에 입력되고, 입력되는 기관의 시간당회전수가 전자제어장치 (40) 내부에서 설정된 일정회전수 이상이되면, 출력측에서 액츄에이터(50)에 제어신호를 출력하여 나비밸브(15)를 회전구동시키므로 고속흡기덕트(12)의 입구가 개방되도록 한다.According to the present invention configured as described above, when the engine 30 is operated, the rotational speed of the engine 30 is input to the electronic controller 40, and the rotational speed of the engine to be input is set within the electronic controller 40. When more than a few, the output side outputs a control signal to the actuator 50 to drive the butterfly valve 15 so that the inlet of the high-speed intake duct 12 is opened.
이러한 본 고안은 기관(30)의 회전속도가 중저속인 경우 만곡 연장되어 비교적 길게 형성된 흡기덕트(14)만을 통해 흡입공기가 흡입되도록 하고, 기관(30)의 고속회전시는 흡기덕트(14)와 고속흡기덕트(12)가 동시에 공기청정기(10) 내부에 연통되도록 하여 흡기통로가 확장되도록 한다.The present invention is such that when the rotational speed of the engine 30 is a low to medium speed, the intake air is sucked through only the intake duct 14 formed to be relatively long, and the intake duct 14 and the high speed rotation of the engine 30 The high-speed intake duct 12 is simultaneously communicated with the inside of the air cleaner 10 so that the intake passage is expanded.
상기와 같이 구성되고 작동되는 본 고안은, 흡기덕트의 길이가 비교적 길게 형성되므로 흡기소음이 효과적으로 저감되도록 하고, 고속시 2개의 통로를 통해 동시에 공기를 흡입하므로 흡기통로가 확장되는 효과가 되어 흡입효율이 향상되도록 하는 효과가 있다.The present invention is constructed and operated as described above, the length of the intake duct is formed to be relatively long, so that the intake noise is effectively reduced, and at the same time intake of air through the two passages at high speed, the intake passage is expanded effect is effective There is an effect to improve this.
