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.
