exhaust gases

Combustion engine byproducts

Exhaust gases are the byproducts expelled from an engine or combustion process—the spent air and fuel mixture pushed out after burning.

In vehicles, exhaust gases exit through the tailpipe and contain pollutants like carbon monoxide and nitrogen oxides: Catalytic converters reduce harmful exhaust gases.

The term appears in discussions of emissions standards and air quality.
