Diesel Exhaust Gas

Compared to the composition of air, the diesel exhaust gas contains increased concentrations of water vapor (H 2 O) and carbon dioxide (CO 2)—the main combustion products. The concentrations of both H 2 O and CO 2 can vary from a few percent, up to about 12% in diesel exhaust. These combustion products displace oxygen, the concentration of which can vary from a few percent, up to about 17% (compared to 21% in ambient air).
