Cars are an important means of transportation for people to travel. If they are used frequently, maintenance is necessary. If they are used for a long time, there will be various problems. Therefore, today's Xiaobian will introduce you some knowledge about the role of automobile carburetor. Today's Xiaobian will tell you about the role of automobile carburetor?

汽車化油器的作用

Function of automobile carburetor

化油器的作用是將汽油霧化與空氣混合形成可燃混合氣，然后送如各個汽缸。當汽油通過汽油泵送如化油器中的浮子室，在浮子室內有一個量空，它可以通過外界氣體壓力與噴管形成（真空）壓力差，直接將油噴入吼管，變成油滴與吼管上部通過空氣濾清器的空氣混合，化油器還分五大系統，主供油、怠速、加濃、加速、起動。

The function of carburetor is to atomize gasoline and mix it with air to form combustible mixture, which is then sent to each cylinder. When gasoline is pumped through gasoline, such as the float chamber in the carburetor, there is a measuring air in the float chamber. It can form a (vacuum) pressure difference between the external gas pressure and the nozzle, and directly inject the oil into the roar pipe, which becomes oil droplets and mixes with the air passing through the air filter on the upper part of the roar pipe. The carburetor is also divided into five systems: main oil supply, idle speed, enrichment, acceleration and start.

提供發動機啟動、冷啟動、加速、怠速、正常工作等各種工況下的一定數量與濃度的可燃混合氣。它包含有主供油系統、怠速供油系統、過度噴孔、加速泵、節氣門、霧化喉管、阻風門、快怠速機構、空調提速機構、油平面浮子調整裝置等裝置，利用流經主、副腔高速氣流的虹吸作用把汽油從浮子室吸出，同時利用氣流的切割作用將汽油破碎成細小顆粒形成初步混合的混合氣，再經由進氣歧管、進氣門活塞等加熱蒸發形成可燃氣。

Provide a certain amount and concentration of combustible mixture under various working conditions such as engine start, cold start, acceleration, idle speed and normal operation. The utility model comprises a main oil supply system, an idle oil supply system, an excessive spray hole, an acceleration pump, a throttle valve, an atomization throat, a choke valve, a fast idle mechanism, an air conditioning speed-up mechanism, an oil level float adjustment device, etc., which uses the siphon effect of the high-speed air flow through the main and auxiliary cavities to suck gasoline out of the float chamber, At the same time, the gasoline is broken into fine particles by the cutting effect of air flow to form a preliminary mixed mixture, which is then heated and evaporated through the intake manifold and intake valve piston to form combustible gas.

空氣在進氣沖程的吸力作用下，以較高的流速流經化油器。

The air flows through the carburetor at a higher flow rate under the suction of the intake stroke.

空氣流經化油器喉管（氣道截面積縮小部位）形成真空度，連接浮子室的噴管口也在喉管處，油從噴管吸出，高速進氣氣流將被吸入化油器喉管的汽油吹散和霧化，形成可燃混合氣進入氣缸。

The air flows through the carburetor throat (where the cross-sectional area of the airway is reduced) to form a vacuum. The nozzle port connecting the float chamber is also at the throat. The oil is sucked out from the nozzle, and the high-speed intake air flow will be blown and atomized by the gasoline sucked into the carburetor throat to form a combustible mixture into the cylinder.
