Heavy-Duty Diesel Fuel Analysis
The EPA's heavy-duty diesel fuel analysis program sought to quantify the air pollution emission effects of diesel fuel parameters on various nonroad and highway heavy-duty diesel engines.
The program examined the
- hydrocarbon (HC)
- oxides of nitrogen (NOx)
- and particulate matter (PM)
emission impacts of diesel fuel parameters; including such parameters as
- cetane number
- aromatics content
- and fuel density.
The program was a short-term effort to perform a thorough analysis of existing data.
