Abstract

Wood stoves, off road vehicles, snowmobiles, etc. contribute to total particulate emissions a far greater fraction than is represented by the fraction of the total energy that they release because their emissions are uncontrolled. Fine particles in the atmosphere originate with both direct emissions and their generation by secondary reactions of SO₂, NO_x, and volatile organic hydrocarbons in the atmosphere. A discussion covers the particulate characterization for both ambient and source particles; mechanisms of fine particle formation; models for calculating emissions; mobile sources that dominate the emissions of organic particles; results of studies performed on a number of on- and off-road vehicles and military aircraft; and soot forms under fuel-rich conditions where hydrocarbon fragments have a greater chance of colliding with other hydrocarbon fragments and growing rather than being oxidized to CO, H₂, CO₂, and H₂O.
