AUTOMATIC CHOKE Meaning and
Definition
-
An automatic choke is a mechanical device found in some older models of automobiles that is responsible for regulating the air-fuel mixture during a vehicle's cold start-up process. It is a key component of the carburetor system, ensuring a smooth and efficient engine operation.
When a vehicle engine is cold, it requires a richer fuel mixture to start and run smoothly. The automatic choke accomplishes this by limiting the amount of air entering the carburetor and increasing the fuel flow. By restricting the air supply, it creates a more fuel-rich mixture necessary for starting the engine, as cold engines need more fuel to ignite and sustain combustion.
The automatic choke operates based on the engine's temperature. When the engine is cold, a bimetallic coil in the choke mechanism expands due to the heat generated by the exhaust manifold or coolant. This expansion closes the choke plate, causing a reduction in the air supply. As the engine warms up, the bimetallic coil contracts, gradually opening the choke plate, allowing more air to enter and adjusting the fuel mixture to a leaner ratio, suitable for normal operation.
As modern vehicles now rely on electronic fuel injection systems, the automatic choke has become obsolete. However, it remains a vital part of older carbureted engines, ensuring a proper fuel-to-air ratio during cold starts for a smooth running engine.

Etymology of AUTOMATIC CHOKE
The word "automatic choke" consists of two parts: "automatic" and "choke".
The term "automatic" comes from the Greek word "automatos", meaning "self-moving" or "self-thinking". It entered English in the early 19th century as a technical term associated with machinery that could operate independently or perform certain actions automatically without human intervention.
On the other hand, "choke" refers to a device that regulates the amount of air entering a carburetor in an internal combustion engine. It restricts the flow of air to create a richer fuel mixture during cold starts when the engine requires a higher fuel-to-air ratio. "Choke" originated from the Old English word "ceocian", which meant "to strangle" or "to suffocate".
