The objective of this project was to characterize crankcase or 'blowby' emissions from two in-service diesel engines, developing and demonstrating methodology for analyses where none existed. Methodology development and demonstration was performed using a dynamometer mounted Detroit Diesel 6V-71, and characterization was done on a Cummins NTC-350 and another 6V-71. Gaseous emissions measured included: emission mass rate; HC, CO, CO2, and NOx (both exhaust and crankcase emissions); individual hydrocarbons; aldehydes; and N-dimethylnitrosamine. Crankcase particulate measurements included: mass rate; concentration; size distribution; elemental composition; sulfate; total solubles; BaP in solubles; boiling range of solubles; and N-dimethylnitrosamine. These measurements were made using variations of the standard 13-mode diesel procedure.
