vehicle exhaust
Fumes from cars
Vehicle exhaust is the mixture of gases and particles expelled from an engine's tailpipe after fuel combustion.
It contains carbon dioxide, carbon monoxide, nitrogen oxides, and unburned hydrocarbons—pollutants that contribute to smog and respiratory problems.
Catalytic converters reduce some harmful emissions, but vehicle exhaust remains a major source of urban air pollution: The garage filled with vehicle exhaust.
