What does carburate mean?
Carburate is a technical verb meaning to combine, mix, or charge something with carbon, most commonly applied to enriching a gas or fuel with volatile hydrocarbons so that it burns more efficiently or brightly. Historically, engineers carburated lean gases such as water gas by blending them with heavier hydrocarbon vapours, raising their calorific value for lighting and heating. The word belongs chiefly to the registers of chemistry and mechanical engineering, and its legacy survives in the name of the carburetor — the device that once 'carburated' the air–fuel mixture in virtually every petrol engine. Though less common now that fuel injection dominates, carburate remains useful in discussions of metallurgy and historical gas manufacture, where precise language about carbon enrichment still matters.
verbTo combine, mix, or charge a substance with carbon, especially to enrich a gas or fuel by adding volatile hydrocarbons.
- To combine or charge a substance with carbon.
- To enrich a gas or fuel mixture with hydrocarbons so it burns more readily.
"The engineer carburated the lean gas mixture to improve combustion efficiency."
"Early gas engineers carburated water gas with benzene vapours to give it a higher heating value."
"The process carburates the surface of the steel, hardening it for wear resistance."
Before fuel injection took over, every petrol engine relied on a device named after this very word — the carburetor, literally the thing that 'carburates' your fuel.

Etymology of carburate
Carburate derives from 'carburet', a formation based on 'carbon', which traces back through French to the Latin 'carbo', meaning charcoal or coal. The word entered scientific English in the 18th and 19th centuries as chemists studied compounds of carbon with metals and the practice of enriching gases. Its cognates include carbonate, carbide, and carburize, all built on the same Latin root, while the derived noun carburation and the familiar carburetor preserve the term in engineering vocabulary.

How carburate is actually used
A technical term used mainly in chemistry and mechanical engineering; largely superseded in everyday contexts by 'carburet' historically and by modern fuel-system vocabulary today.
Easily confused with carburate
Carburet is the older spelling of the same verb (and of the noun meaning a carbon compound), while carburate is the later, more common form.
