During the mixing of hot combustion gas containing NO with cold air, NO₂ is formed through the oxidation of NO. In this study, using hot combustion gas-cold air double concentric jets, the effect of methane and propane on this type of NO₂ formation has been experimentally investigated. The methane (below 2530ppm) and propane (below 148ppm) were added to the cold air, and NO and NO₂ concentrations were determined by a chemiluminescent analysis. The equivalence ratio of the combustion gas was varied from 0.76 to 1.20. It was found that the addition of low levels of methane and propane can significantly promote NO₂ formation. Propane was found to promote NO₂ formation much more effectively than methane. The difference of their effectiveness is discussed in view of hydrocarbon reactions in smog formation. From the above results, the level of hydrocarbons in the mixing region of combustion gas with air is one of the important factors controlling the direct emission of NO₂ from combustion systems.
