Exhaust gas
From Freepedia
(Redirected from Exhaust fumes)
Exhaust gas is gas which occurs as a result of combustion of fuel such as gasoline/petrol, diesel or coal. It is discharged to atmosphere through an exhaust pipe or chimney.
Although much of it is relatively harmless carbon dioxide, part of it is noxious or toxic substances, such as carbon monoxide (CO), hydrocarbons, nitrogen oxides (NOx), and particulate matter. Diesel exhaust has a characteristic smell.
Emission standards often focus on reducing pollutants contained in exhaust gas.
