Kaasukartturi

Kaasukartturi, which translates to "gas carburetor" in English, is a component found in many internal combustion engines. Its primary function is to mix air and fuel in the correct ratio for combustion. This mixture is then drawn into the engine's cylinders to be ignited by a spark plug.

The carburetor works by utilizing the Venturi effect. As air flows through a narrowed section of the carburetor, its speed increases and its pressure decreases. This low-pressure area draws fuel from a fuel bowl through a jet. The fuel then atomizes into fine droplets and mixes with the incoming air. Different jets and passages within the carburetor control the air-fuel mixture for various engine operating conditions, such as idling, acceleration, and full throttle.

The design of a carburetor can vary, but most include a float chamber to maintain a constant fuel level, a throttle valve to regulate the amount of air entering the engine (and thus controlling engine speed), and various jets for fuel delivery. In older vehicles and smaller engines like those found in lawnmowers and motorcycles, carburetors were a common fuel delivery system. However, with advancements in technology, they have largely been replaced by fuel injection systems in modern automobiles due to their greater precision, fuel efficiency, and emission control capabilities. Despite this, carburetors remain relevant in many applications where simplicity and cost-effectiveness are prioritized.
