karburaatorisüsteem

A karburaatorisüsteem, more commonly known as a carburetor system, is a mechanical device responsible for mixing air and fuel in a specific ratio for combustion in internal combustion engines. Its primary function is to atomize liquid fuel into fine droplets and combine it with incoming air before it enters the engine cylinders. This precise mixture is crucial for efficient engine operation and performance.

The core components of a carburetor include a Venturi tube, a throttle valve, and a fuel jet. As air flows through the Venturi, its velocity increases, creating a low-pressure area that draws fuel from the fuel bowl through the jet. The throttle valve, controlled by the accelerator pedal, regulates the amount of air-fuel mixture entering the engine, thus controlling engine speed and power. Different types of carburetors exist, such as simple, compound, and downdraft carburetors, each designed for specific engine applications and performance characteristics. Carburetors were a standard fuel delivery system for gasoline engines for many decades before being largely replaced by fuel injection systems due to their superior fuel efficiency, emissions control, and performance in modern vehicles.
