Definition
Meaning and Definition
The process of mixing air with a fine spray of liquid fuel in the correct proportion for combustion in an internal combustion engine.
Technically, it refers specifically to the function of a carburetor. More generally, it can be used to describe the overall fuel-air mixing and delivery system in older, non-fuel-injected engines.
Dialectal Variation
British vs American Usage
Differences
The term is recognized in both varieties, but 'carburation' is the more common British English spelling variant, though 'carburetion' is also used. 'Carburetion' is the standard American spelling.
Connotations
In both varieties, it connotes older, classic, or less sophisticated engine technology compared to modern fuel injection.
Frequency
Equally low frequency in both dialects, limited to automotive enthusiasts, mechanics, and engineers. The American spelling 'carburetion' may be more globally recognized due to the influence of American automotive literature.

FAQ
Frequently Asked Questions
No, they are distinct and largely successive technologies. Carburetion uses a mechanical device (a carburetor) to mix air and fuel via vacuum and pressure. Fuel injection uses electronically controlled injectors to spray fuel directly into the intake manifold or cylinder.
Virtually no mass-produced cars have used carburetion since the late 1980s or early 1990s, due to the superior efficiency, performance, and emissions control of fuel injection. It survives only in some small engines (e.g., lawnmowers, generators) and the classic/vintage vehicle market.
'Carburetor' is the name of the physical device that performs the mixing. 'Carburetion' is the name of the *process* or *function* of mixing the air and fuel that is carried out by that device.
It is a technological fossil. As the technology (the carburetor) has been superseded by fuel injection in almost all applications, the specific term for its function has naturally fallen out of everyday and even most technical use, except in historical or niche restoration contexts.
The process of mixing air with a fine spray of liquid fuel in the correct proportion for combustion in an internal combustion engine.
Carburetion is usually technical/historical in register.

Learning
Memory Aids
Mnemonic
Think: CAR + BUREAU (like an office) + TION. The carburetor is like the 'fuel office' of an old engine, where carburetion—the mixing of air and fuel—happens.
Conceptual Metaphor
The carburetor is the LUNGS/HEART of the engine (mixing life-giving air with fuel). Carburetion is the BREATHING/CIRCULATION process.
