CO2 in Garages and Tunnels
Modern vehicle engines emit many harmful substances including carbon monoxide (CO), carbon dioxide (CO2), nitrogen oxides (NOx), hydrocarbons and some 20 other gases. Internal combustion engines produce CO during a cold start. To protect people from this toxic gas, a catalytic converter is usually installed as part of the exhaust system. A warm running modern engine with a catalytic converter installed generates 140 times more CO2 than CO.
