Emissions From a 6.5L HMMWV Engine on Low Sulfur Diesel Fuel and JP-8

摘要

This project investigated the exhaust emissions produced at various operating conditions by the 6.5L diesel engine that is used to power the Army's GMMWV. Compared to reference diesel fuel, the use of JP-8 fuel resulted in lower levels of NOx and particulate matter. Polycyclic aromatic hydrocarbons (PAH's) were also determined. The JP-8 produced lower levels of exhaust PAH's than the low sulfur certification diesel fuel (LSCD) for most but not all PAH type.
