본 발명은 흡기밸브의 보조 공기유입장치에 관한 것이다.The present invention relates to an auxiliary air inlet device of the intake valve.
종래의 엔진 흡기밸브는 초우크밸브의 개폐에 따라 흡기매니폴드로 유입되는 양만큼의 혼합기를 연소실 내로 공급하도록 캠에 의하여 상하왕복운동하고 있다.Conventional engine intake valves are reciprocated vertically by cams so as to supply the amount of mixers introduced into the intake manifold into the combustion chamber as the choke valve opens and closes.
그러나, 공전시나 저부하시에는 연소실 내가 진공상태로 되어 잔류가스가 잘 빠져나가지 못해 점화상태가 불량하기 쉽고 연소효율을 저하시키는 원인이 되기도 하고 있었다.However, during idle or low load, the combustion chamber is in a vacuum state, and residual gas does not escape well, causing poor ignition and lowering combustion efficiency.
본 발명의 목적은 기존의 흡기 매니폴드를 거치지 않은 다른 공기유입경로를 개설하여 흡기밸브를 통하여 연소실 내로 보조적인 공기의 유입이 가능하도록 하므로서 양호한 점화상태의 유도와 연소효율의 향상을 이루고자 하는데 있는 것이다.An object of the present invention is to establish a good ignition state and to improve combustion efficiency by establishing another air inflow path not passing through the existing intake manifold to allow auxiliary air to be introduced into the combustion chamber through the intake valve. .
본 발명은 상기 목적을 달성하기 위하여, 초우크밸브 전방의 기화기와 실린더헤드의 흡기밸브측 벽면간에 보조공기유입로를 개설하고, 흡기밸브의 하부에는 플런저 시트를 갖는 ㄱ자형의 플러저 유동공간을 형성하며, 이 플런저 유동공간내에는 상기 실린더 헤드의 보조공기유입로와 일단이 결합되는 ㄱ자형의 유입파이프가 벨브 리프트의 크기만큼 상하유동 가능하게 삽입되고, 상기 유입파이프에는 상기 플런저 유동공간의 플런저 시트와 밀착가능한 헤드를 갖는 플런저의 상단을 나사체결시킨 것이다.In order to achieve the above object, the present invention establishes an auxiliary air inflow path between the vaporizer in front of the choke valve and the intake valve side wall of the cylinder head, and has an L-shaped plunger flow space having a plunger seat in the lower part of the intake valve. In the plunger flow space, the inlet pipe having an end coupled to the auxiliary air inlet of the cylinder head is inserted into the plunger so as to flow up and down by the size of the valve lift, and the plunger in the plunger flow space. The upper end of the plunger having the head close to the seat is screwed in.
본 발명은 상기와 같은 구성에 따라, 흡기밸브가 리프트되면 플런저가 플런저 유동공간을 막아 보조공기유입로가 차단되고 흡기밸브가 개방되면 플런저의 헤드가 플런저 유동공간을 열어 보조공기유입로가 개방되므로 인하여 공기가 연소실 내로 공급된다.According to the above configuration, when the intake valve is lifted, the plunger blocks the plunger flow space so that the auxiliary air inflow path is blocked, and when the intake valve is opened, the head of the plunger opens the plunger flow space to open the auxiliary air inflow path. Air is thus fed into the combustion chamber.
이하 본 발명의 실시예를 첨부된 도면에 의하여 설명한다.Embodiments of the present invention will now be described with reference to the accompanying drawings.
본 발명은 제1도 및 제 2도와 같이 초우크밸브(1) 전방의 기화기(2)와 실린더 헤드(3)의 흡기밸브(4)측 벽면간에 보조공기유입로(5)를 개설하고, 흡기밸브(4)의 하부에는 플런저 시트(6)를 갖는 ㄱ자형의 플런저 유동공간(7)을 형성하며, 이 플런저 유동공간(7)내에는 상기 실린더 헤드(3)의 보조공기유입로(5)와 일단이 결합되는 ㄱ자형의 유입파이프(8)가 밸브 리프트의 크기만큼 상하유동 가능하게 삽입되고, 상기 유입파이프(8)에는 상기 플런저 유동공간(7)의 플런저 시트(6)와 밀착 가능한 헤드를 갖는 플런저(9)의 상단을 나사체결시킨 것이다.The present invention establishes an auxiliary air inflow passage 5 between the vaporizer 2 in front of the choke valve 1 and the wall surface of the intake valve 4 side of the cylinder head 3 as shown in FIGS. A lower portion of the valve 4 is formed with an L-shaped plunger flow space 7 having a plunger seat 6, and in the plunger flow space 7 an auxiliary air inflow path 5 of the cylinder head 3. And an inlet pipe (8) having one end coupled therein to be inserted up and down by the size of the valve lift, and the head in close contact with the plunger seat (6) of the plunger flow space (7) in the inlet pipe (8). The upper end of the plunger (9) having screwed.
따라서, 흡기밸브(4)가 리프트되면 플런저(9)가 플런저 유동공간(7)을 막아 보조공기유입로(5)가 차단되고 흡기밸브(4)가 개방되면 플런저(9)의 헤드가 플런저 유동공간(7)을 열어 보조공기유입로(5)로 개방되므로 인하여 공기가 연소실(10)내로 공급된다.Therefore, when the intake valve 4 is lifted, the plunger 9 blocks the plunger flow space 7 so that the auxiliary air inflow passage 5 is blocked, and when the intake valve 4 is opened, the head of the plunger 9 is plunged. Since the space 7 is opened to the auxiliary air inlet 5, air is supplied into the combustion chamber 10.
상기와 같이 구성된 본 발명은 혼합기 이외의 공기가 연소실 내로 유입되므로 인하여 공전시나 저부하시 연소실 내의 잔류가스가 상기 공기로 인하여 쉽게 배출되고, 신선한 공기의 공급으로 인해 점화상태가 개선되며, 압축행정시 강한 스월(swirl)을 야기시켜 높은 연소효율을 얻게 되고, 이로 인해 탄산가스의 발생 또한 억제되는 효과가 있는 것이다.According to the present invention configured as described above, since the air other than the mixer is introduced into the combustion chamber, the residual gas in the combustion chamber is easily discharged due to the air at idle or low load, and the ignition state is improved due to the supply of fresh air. By causing a strong swirl (swirl) to obtain a high combustion efficiency, which also has the effect of suppressing the generation of carbon dioxide gas.
