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?

汽车化油器的作用

Function of automobile carburetor

化油器的作用是将汽油雾化与空气混合形成可燃混合气，然后送如各个汽缸。当汽油通过汽油泵送如化油器中的浮子室，在浮子室内有一个量空，它可以通过外界气体压力与喷管形成（真空）压力差，直接将油喷入吼管，变成油滴与吼管上部通过空气滤清器的空气混合，化油器还分五大系统，主供油、怠速、加浓、加速、起动。

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.

提供发动机启动、冷启动、加速、怠速、正常工作等各种工况下的一定数量与浓度的可燃混合气。它包含有主供油系统、怠速供油系统、过度喷孔、加速泵、节气门、雾化喉管、阻风门、快怠速机构、空调提速机构、油平面浮子调整装置等装置，利用流经主、副腔高速气流的虹吸作用把汽油从浮子室吸出，同时利用气流的切割作用将汽油破碎成细小颗粒形成初步混合的混合气，再经由进气歧管、进气门活塞等加热蒸发形成可燃气。

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.

空气在进气冲程的吸力作用下，以较高的流速流经化油器。

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

空气流经化油器喉管（气道截面积缩小部位）形成真空度，连接浮子室的喷管口也在喉管处，油从喷管吸出，高速进气气流将被吸入化油器喉管的汽油吹散和雾化，形成可燃混合气进入气缸。

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.
