How is unburned fuels formed
WebWe conducted photo-oxidation experiments in a smog chamber to investigate secondary organic aerosol (SOA) formation from eleven different unburned fuels: commercial gasoline, three types of jet fuel, and seven different diesel fuels. The goals were to investigate the influence of fuel composition on SOA formation and to compare SOA … WebAlthough no one knows exactly what smog is or how it is formed, some investigators(G78)agree that hydrocarbons (particu- larly olefins), nitrogen oxides, and ozone are important in the mechanism of smog formation. The second reason for this interest is fuel conserva- tion.
