Effects of Fuel Oxygenates, Cetane Number, and Aromatic Content on Emissions from1994 and 1998 Prototype Heavy-Duty Diesel Engines

摘要

The Coordinating Research Council-Air Pollution Research Advisory Committee (CRC-APRAC) developed the VE-10 Project to determine the effects of selected fuel properties on heavy-duty diesel engine emissions. In the first part, the VE-10 Project examined the effects of cetane number, aromatic level, and oxygen content of diesel fuel on regulated and selected unregulated emissions from two heavy-duty diesel engines calibrated for 1994 emission levels. In the second part of VE-10, cetane number effects on emissions from prototype 1998 heavy-duty engine were examined.
