CARBURETORS Meaning and
Definition
-
Carburetors are mechanical devices used in internal combustion engines to blend air and fuel in the correct proportions for optimal combustion. This dictionary definition will elaborate on the function, components, and historical significance of carburetors.
A carburetor works by utilizing the Bernoulli principle and the Venturi effect to create a low-pressure area that draws fuel into the incoming air stream. These devices are commonly found in older vehicles but have mostly been replaced by fuel injection systems in modern cars. However, carburetors are still used in small engines such as those found in lawnmowers and motorcycles.
The main components of a carburetor include a venturi, throttle plate, float chamber, and jets. The venturi is a narrow passage that increases air velocity, creating low pressure and facilitating fuel discharge. The throttle plate controls the amount of air entering the engine, adjusting the engine's speed accordingly. The float chamber houses the float and fuel supply to regulate fuel levels, and the jets control the amount of fuel flowing into the air stream.
Although carburetors have gradually been replaced by more efficient fuel injection systems, they played a crucial role in the automotive industry's growth and development. Carburetors made fuel delivery more efficient and improved engine performance by ensuring an optimal air-fuel mixture. Despite their historical significance, modern vehicles now rely on electronic fuel injection for greater precision in fuel delivery, emissions control, and overall engine performance.

Etymology of CARBURETORS
The word "carburetor" comes from the French word "carburateur" which is derived from "carburant" meaning "fuel". It was coined in the late 19th century to describe a device that mixes air and fuel for an internal combustion engine. The term "carburetor" is formed by combining the prefix "carb-" from "carburant" meaning "fuel" and the suffix "-eur" which designates the tool or device used for a specific purpose.
