Study of fuel cetane number and aromatic-content effects on regulated emissions from a heavy-duty diesel engine. Final report
As heavy-duty diesel engine manufacturers strive to meet stringent emission requirements, the relationship between regulated emissions and fuel properties has become increasingly important. Emissions of particulate and NOx are of special interest because control of these pollutants represents a major problem for the diesel engine. Earlier study VE-1 study results indicated that fuel aromatic content was correlated with cetane number. To determine the effects of cetane number, cetane improver, and fuel aromatics on exhaust emissions (NOx, particulate, HC, and CO), a follow-on study was developed by the VE-1 Group and is reported herein as Phase II of the VE-1 project. The study determined cetane number is the fuel property affecting hydrocarbon and carbon monoxide emissions. Both cetane number and aromatic content affect NOx emissions and cetane number and possibly aromatic content affect particulate emissions.
