ICCT-sponsored study of in-use testing of 3 Tier2-Bin5, CA LEV-II light-duty diesels finds wide variation of emissions against the limits

Green Car Congress

The test plan covered a wide variety of topological, road and ambient conditions as well as traffic densities over three major urban areas along the West coast—San Diego, Los Angeles, and San Francisco. Overall, urban/suburban driving leads to a 32-39% reduction in fuel economy over highway driving.

At idle and low loads, rebreathing of hot exhaust gases provided stable compression ignition with very low engine-out NO x and PM emissions. Rebreathing enabled reduced boost pressure, while greatly increasing exhaust temperature. Hydrocarbon and carbon monoxide emissions after the oxidation catalyst were very low. Earlier post.).
