Green-Diesel school bus as clean or cleaner than CNG: study
Diesel Fuel News, Nov 25, 2002 by Jack Peckham
Except for the 14-ppm sulfur limit, the ULSD fuel used in the tests was much like ordinary diesel in all respects. ULSD aromatics (by volume) were actually higher (31.8%) than conventional EPA diesel certification fuel (27.5vol%). Cetane number was the same for both fuels (47.7).
Even the conventional (not "green-diesel"), 2001-model diesel bus tested on ordinary diesel fuel was relatively low in emissions, contradicting claims by certain "green" groups that all existing diesel buses somehow pose an equally "toxic" threat.
