What is the function of a carburetor?

The function of a carburetor is to mix a certain proportion of gasoline with air under the vacuum generated by the engine's operation. As a precision mechanical device, the carburetor utilizes the kinetic energy of the incoming air stream to atomize the gasoline, playing a crucial role in the engine—often referred to as the heart of the engine. A complete carburetor assembly should include a starting device, an idle device, a medium-load device, a full-load device, and an acceleration device. The carburetor automatically adjusts the mixture ratio according to the engine's different operational states, delivering the corresponding amount of air-fuel mixture. To ensure the mixture is uniformly blended, the carburetor also has the effect of atomizing the fuel for smooth engine operation.
Oh, I've driven quite a few old cars. The carburetor is that thing which mixes gasoline and air into a mist-like fuel, allowing the engine to burn smoothly and work properly. Simply put, it's like a bartender, atomizing the gasoline and mixing it with air in the right proportion. If the ratio is off, the car will have trouble starting, lack power when accelerating, or emit excessive smoke. I remember carburetor carbon buildup was a common issue when repairing cars in the past—if the fuel line got clogged, it was hard to start, especially in winter when it was prone to freezing and stalling. Nowadays, new cars use electronic fuel injection systems, which are more efficient and eco-friendly, but old cars still rely on carburetors. For maintenance, you need to regularly clean carburetor parts like the nozzle and float to avoid roadside breakdowns that could affect driving safety. Don't overlook these small components—they're crucial for fuel efficiency and performance.
