Description

자동차 기화기의 2차 공기 공급기Secondary air supply of car carburetor

제 1 도는 본 고안의 종단면도.1 is a longitudinal sectional view of the present invention.

본 고안은 자동차 기화기와 흡입매니홀드 사이에 설치되는 2차공기 공급기에 관한것으로서, 급기관을 기체 측방으로부터 내공중심부까지 관통시킨 단부에 급기소공이 다수 천공된 공기 공급통을 나착하여 제작을 편리하게 하여 생산비를 절감하고 원형 공기공급통의 급기소공의 청소를 매우 용이하게 할 수 있도록 하는 한편, 급기관상에 급기량을 조절할 수 있는 밸브를 드로틀밸브와 연동토록 장설하여 드로틀밸브가 닫치면 급기를 하고 열리면 급기공을 막아서 불필요한 공기공급을 피하여 엔진회전상태를 양호하게 함을 목적으로한 것이다.The present invention relates to a secondary air supply unit installed between an automobile carburetor and a suction manifold, and is easily manufactured by attaching a plurality of air supply holes perforated to the end through which the air supply pipe passes from the side of the gas to the inner center of the air. In order to reduce the production cost and make the air supply hole of the circular air supply tank very easy to clean, install a valve to control the air supply amount in the supply pipe so as to interlock with the throttle valve to supply air when the throttle valve is closed. When opened, it aims to improve the engine rotation state by blocking the air supply hole and avoiding unnecessary air supply.

종래의 자동차 기화기 저부에 장설되는 2차공기 공급기의 구성은 기체측면으로부터 삽입된 급기관을 중심부까지 관통하되, 중심공의 상부 외주연에 홈을 요설하고 이로부터 급기소공을 다수 천공하여 급기관과 연통되게한 것이므로 이 부분의 형성작업이 복잡하여 생산 단가가 높아지는 폐단이 있었고, 또 이 급기소공이 막힐경우에 이를 청소하기가 불편하였으며 제작당시서부터 급기공수에 관련하여 급기량이 한정되어 있으므로 엔진의 노후상태에 적절한 공기공급량을 조절할 수 없고 항상 고정량이 흡기되므로 엔진의 회전상태가 양호하지 못한 결점이 있었다.The configuration of the secondary air supply installed in the bottom of the conventional car vaporizer is to penetrate the air supply pipe inserted from the gas side to the center, and the groove is formed in the upper outer periphery of the central hole, and a plurality of air supply holes are drilled therefrom. Since the formation work of this part was complicated, there was a closed end to increase the production cost, and it was inconvenient to clean it when this air supply hole was blocked, and since the air supply was limited in relation to the air supply from the time of manufacture, There was a drawback that the engine was not rotated well because the air supply could not be adjusted to the old condition and the fixed amount was always intake.

이와 같은 종래의 제반결점과 문제점을 해결할 목적으로 개량된 본 고안의 2차공기 공급기를 첨부도면에 의하여 상술하면 다음과 같다.When described in detail by the accompanying drawings, the secondary air supply of the present invention improved for the purpose of solving the conventional drawbacks and problems as described above.

기화기(1)와 흡입매니홀드(2) 사이에 설치할 수 있게 형성된 기체(3)의 일측에 연설부(3a)를 형성하여 이로부터 급기관(4)을 내측에 나착하고 그 첨단에 상부로급기소공(5a)(5b)이 다수 천공된 원형공기 공급통(6)을 나착하고 연설부(3a)에 조절밸브(7)를 유삽하여 드로틀밸브의 축봉(8) 일단에 링크(9)로 연동케 장설한 것이다.Speech portion 3a is formed on one side of the body 3 formed so as to be installed between the vaporizer 1 and the suction manifold 2, from which the air supply pipe 4 is attached to the inside and the upper side Attaching a circular air supply cylinder 6 having a plurality of small holes 5a and 5b perforated, and inserting a control valve 7 into the protruding portion 3a and interlocking with a link 9 at one end of the shaft rod 8 of the throttle valve. It is laid.

미설명부호 10은 에어크리너를 표시한 것이다.Reference numeral 10 denotes an air cleaner.

이와 같이된 본 고안은 엔진의 회전시에 흡입매니홀드(2)내에는 부압이 형성됨에 따라 에너크리너(10)에서 정화된 공기가 급기관(4)을 통하여 원형 공기공급통(6)의 급기소공(5a)(5b)으로 공급되어 연소실내의 충분한 공기의 공급으로 완전연소될 수있게 되어 유해가스의 배출을 줄이고 따라서 동력의 증가로 연료를 절약할 수 있게 되는 작용은 종래의 것과 동일한 것이다.According to the present invention as described above, as the negative pressure is formed in the suction manifold 2 when the engine rotates, the air purified by the energy cleaner 10 is supplied through the air supply pipe 4 through the air supply pipe 4. The action of being supplied to the small holes 5a and 5b to be completely burned by supplying sufficient air in the combustion chamber to reduce the emission of harmful gases and thus to save fuel by increasing power is the same as the conventional one.

그러나, 본 고안에서의 드로틀밸브가 닫치면 닫칠수록 밸브(7)가 더욱 열려서 적절한 2차공기를 공급하게 되고 드로틀밸브가 열리면 밸브(7)가 닫쳐서 적절한 유입공기의 변동에 쉽게 적용될 수 있고, 엔진의 실린더 압축이 떨어지면서 부압도도 떨어지므로 이에 적절한 공기 공급량을 엔진의 회전상태에 알맞게 결정할 수 있으므로 종래의 것과는 달리 보다 진보적이고 보다 적절한 2차공기를 공급할 수 있는 효과가 있고 구조의 간단으로 생산비를 절감할 수 있으므로 저렴한 가격의 2차공기 공급기를 제공할 수 있는 등의 실용성이 있고, 원형공기 공급통(6)의 공기소공(5a)(5b)의 청소가 편리한 잇점도 있는 것이다.However, as the throttle valve closes in the present invention, the more the valve 7 is opened to supply the appropriate secondary air, and the valve 7 is closed when the throttle valve is opened, so that it can be easily applied to the fluctuation of the proper inlet air. As the cylinder compression of the engine decreases and the negative pressure decreases, the appropriate air supply can be determined according to the rotational state of the engine. Therefore, unlike the conventional method, it is possible to supply more advanced and more appropriate secondary air, and the production cost is simple. Since it can be reduced, there is practical use such as providing a low-cost secondary air supply, and there is also an advantage in that cleaning of the air holes 5a and 5b of the circular air supply cylinder 6 is convenient.
