Abstract (summary)

Particle size distributions in diesel exhaust were studied using a thermal desorption technique to determine the volatile and non-volatile fractions. A thermal denuder was designed and characterized for optimal operating parameters and its influence on the exhaust chemistries studied using diesel engine exhaust. The study was conducted on a 1992 DDC Series 60 engine mounted on a heavy-duty direct current dynamometer and exercised over steady state and transient cycles. The particle size distributions were recorded upstream and downstream of the denuder maintained at different temperatures to determine the behavior of the volatile fraction. The volatilization technique was also applied to the crankcase emissions in light of the 2007/2010 EPA regulations. The SMPS was used to obtain the particle size distributions from the sample gases diluted by an ejector diluter system. With the removal of the volatile fraction from the sample exhaust a shift in the size distribution towards the lower end of the spectrum was observed. (Abstract shortened by UMI.)
