In most carburetor heat systems, warm air is drawn initially from the compartment and further heated by being passed through a muff or heat exchanger around the manifold, before being ducted to the carburetor.

Carburetor icing is prevented by providing warm air to the carburetor. The air is first drawn from the engine compartment, then warmed further by passing it through a heater muff or heat exchanger that surrounds the exhaust manifold. The heated air is then ducted to the carburetor, using waste heat from the exhaust to raise the air temperature without letting exhaust gases enter the intake. This arrangement relies on exhaust heat to condition the air and keeps the heat source localized to the engine area, rather than pulling air from cabin or cockpit or from other unrelated paths.

In most carburetor heat systems, warm air is drawn initially from the ______ compartment and further heated by being passed through a muff or heat exchanger around the ______ manifold, before being ducted to the carburetor.
