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.
