Measurement of primary exhaust particulate matter emissions from light-duty motor vehicles. Final report
An in-use fleet of 60 gasoline-fueled and 8 diesel-fueled vehicles was evaluated to characterize primary particulate exhaust emissions. The candidate vehicles included light-duty passenger cars and trucks, and passenger trucks with heavy-duty engines. The six visibly smoking gasoline-fueled vehicles were chosen from a pool of over 30 smoking vehicles because they emitted smoke during virtually all operating conditions (idle, acceleration, deceleration, and cruise). Primary particulate exhaust emission samples were characterized for total mass emission rate, PM-10, PM-2.5, organic and elemental carbon fraction, trace elements, sulfates, nitrates, and the presence of select polynuclear aromatics, hopanes, and steranes. In addition, particle mass size distribution and particle number concentration were measured for a subset of vehicles. Gaseous and particulate exhaust emissions were evaluated using the Federal Test Procedure (FTP).
