Through cooperative research, the Chemical Characterization Panel of the CRC-APRAC Program Group on Composition of Diesel Exhaust has worked to improve characterization of unregulated diesel emissions and to validate chemical analysis methods for measuring diesel-exhaust constituents. In Part I, the Panel dealt with extraction of the organic fraction from diesel particulate matter, including investigation of various solvents and laboratory techniques. Part II of the CRC-APRAC Diesel Particulate Extract Study expanded the previous research to heavy-duty diesel engines operating under transient test conditions of the U.S. EPA Heavy-Duty Diesel Certification Test Procedures. The Panel extended its extraction and characterization studies to include samples from the Engine Manufacturers Association (EMA) and the U.S. EPA Mobile Sources Laboratory round-robin program to determine inter-laboratory and test-to-test variability of heavy-duty diesel-engine exhaust emissions for the Transient Test and 13-Mode Steady-State Cycle Tests. Six heavy-duty diesel engines, typical of production engines in the early 1980's with rated power ranging from 150 to 285 kW (200-380 hp) were used in the round-robin program.
