본 발명은 티에스 에이 아이(TSAI; Timed Secondary Air Injection) 라인에 있어서, 특히 TSAI 파이프의 장착 위치를 변화시켜 인젝션의 강도를 증가시키며 배기 가스의 흐름을 방해하지 않도록 한 에어 추가공급 장치에 관한 것이다.The present invention relates to an additional air supply device in a TSAI (Timed Secondary Air Injection) line, in particular, by changing the mounting position of the TSAI pipe to increase the intensity of injection and not to disturb the flow of exhaust gas.
종래 에어(Air) 추가공급 장치는 제1도에 도시된 바와 같이, 에어의 추가공급을 위한 TSAI 파이프(Pipe)(1)가 연손실(2)의 배기 포트(Port)(3)에 결합되어 있는 배기 다기관(4) 내에 장착되어 있다. 상기와 같은 구조로 이루어지게 되는 종래 에어 추가공급 장치는 TSAI 파이프(1)가 배기 다기관(4)내에 위치하게 되므로서, 가공성이 나쁘면 연소실(2)로부터 배기 포트(3)를 통해 배출되는 배기 가스의 흐름에도 영향을 미치게 된다. 따라서, 상기와 같이 배기가스에 영향을 미치게 되므로서, 엔진의 출력에 영향을 주게 된다.In the conventional air additional supply device, as shown in FIG. 1, a TSAI pipe 1 for additional supply of air is coupled to the exhaust port 3 of the annual loss 2. It is mounted in the exhaust manifold 4 which exists. In the conventional air additional supply device having the above structure, since the TSAI pipe 1 is located in the exhaust manifold 4, if workability is poor, exhaust gas discharged from the combustion chamber 2 through the exhaust port 3 is poor. It will also affect the flow of. Therefore, the exhaust gas is affected as described above, thereby affecting the output of the engine.
본 발명에서는 상기와 같은 문제점을 해결하기 위하여 실리더 헤드에 가공되어 있는 냉각용 홀(Hole)을 이용하여 TSAI 파이프와 연결하도록 하므로서, 출력되는 배기가스에 영향을 주지 않으며, 인젝션 강도를 향상시키고자 한 것이다.In the present invention, to solve the above problems by connecting to the TSAI pipe using a cooling hole (Hole) processed in the cylinder head, without affecting the output exhaust gas, to improve the injection strength It is.
도면 제2도는 본 발명 에어 추가공급 장치의 구조를 개략적으로 보인 정면도이고, 도면 제3도는 본 발명 에어추가공급 장치의 측면도인 바, 제2도 및 제3도를 참조하여 본 발명 장치의 구조 및 작용을 설명하면 다음과 같다.Figure 2 is a front view schematically showing the structure of the air additional supply device of the present invention, Figure 3 is a side view of the air additional supply device of the present invention, the structure of the present invention with reference to Figures 2 and 3 and The operation is described as follows.
실린더 헤드(11)의 홀이 뚤리는 위치에 배기 포트(12) 사이를 관통하는 포옴(Foam)(13)을 형성시키고, 상기와 같이 포옴(13)이 형성된 홀에 배기 포트(12)와 연결되도록 하고, 이와 같이 연결된 홀에 TSAI 파이프를 삽입함과 함께 에어 인젝터를 연결하는 구조를 특징으로 한다. 미설명부호 14는 배기다기관, 15는 연소실이다.A foam 13 penetrating between the exhaust ports 12 is formed at a position where the hole of the cylinder head 11 is bent, and the exhaust port 12 is connected to the hole in which the foam 13 is formed as described above. And inserting the TSAI pipe into the connected hole and connecting the air injector. Reference numeral 14 denotes an exhaust manifold, and 15 denotes a combustion chamber.
이와 같이 구조의 본 발명 에어 추가공급 장치는 헤드의 주물가공시 홀이 뚤리는 위치에 배기 포트(12)를 관통하는 포옴(13)을 삽입하여 가공하고, 홀 가공시 배기 포트(12)와 연결되도록 한다. 상기와 같이 형성된 홀에 TSAI 파이프를 압입하고, 에어 인젝터를 함께 연결구성한다. 이와 같은 구조로 이루어지게 되는 배기 다기관(14)내에 구성된 종래에 비해 배기 밸브에 더 가깝게 에어분사가 가능하여 인젝션 강도를 증가시킬 수 있게 된다. 또한, 배기 가스의 흐름을 방해하지 않으므로서, 출력에 아무런 영향을 미치지 않게 되어 엔진의 출력이 향상되며, 가공성이 향상되는 것이다.In the present invention, the additional air supply device of the structure is processed by inserting a foam 13 penetrating through the exhaust port 12 at the position where the hole is bent during the casting of the head, and connected to the exhaust port 12 during hole processing Be sure to The TSAI pipe is pressed into the hole formed as described above, and the air injector is connected together. Compared with the conventional configuration in the exhaust manifold 14 having such a structure, air injection is possible closer to the exhaust valve, thereby increasing the injection strength. In addition, without disturbing the flow of the exhaust gas, the output of the engine is improved without any influence on the output, and the workability is improved.
