The carburetor is an important component of the automotive fuel system, whose main function is to evaporate and mix the car's fuel to form flammable gases, which are supplied to the engine for use. The working principle of a carburetor is to inject liquid gasoline into the airflow inside the carburetor through the nozzle and fuel injector, and then mix with the air to form gasoline gas, which enters the engine for combustion and drives the car forward. Below, we will provide a detailed introduction to the working principle of carburetors.
The carburetor is mainly divided into two parts, one is the fuel supply system, the other is the air supply system.
Fuel supply system
The fuel supply system mainly consists of fuel tank, oil pipe, oil pump, fuel air ratio regulator, main throttle valve, auxiliary throttle valve, float valve, fuel injector, and other parts. The oil pump is mainly responsible for delivering gasoline from the car's fuel tank to the carburetor, while the float valve is mainly used to control the oil level in the fuel tank and ensure the correct ratio of oil and gas.
Oil pumps are mainly divided into two types: mechanical oil pumps and electric oil pumps. The mechanical oil pump relies on the operation of the engine to extract gasoline from the fuel tank and deliver it to the main and auxiliary throttle valves (also known as the fuel air ratio regulator) of the carburetor, controlling the flow rate and gasification ratio of gasoline to achieve the optimal ignition point and achieve power output. The electric oil pump, on the other hand, mainly relies on electric drive to deliver gasoline to the carburetor through the oil pipe.
Air supply system
The air supply system mainly consists of intake pipe, throttle valve, air filter, throttle shaft, accident protection, and speed curve adjuster. The main function of an air filter is to filter and purify the air entering the carburetor, avoiding dust and foreign objects from entering the interior of the carburetor, which affects the quality and mixing ratio of the fuel. The throttle valve can control the amount of air entering the carburetor, in order to adjust the fuel flow rate and mixing ratio, and adjust the engine's operating speed and output power.
The interior of the carburetor mainly consists of float valves, fuel injectors, carburetor chambers, electric heaters, and other parts. After gasoline is sprayed out of the fuel nozzle, it will mix with air and form a combustible gas that enters the engine for combustion, generating power to drive the car.
To sum up, the working principle of the carburetor is to generate combustible gas by mixing gasoline and air, so that the engine can run normally and efficiently, and ensure the normal driving of the car. Currently, with the development of technology, carburetors have gradually been replaced by fuel injection systems, but their core principles remain unchanged.
