Exhaust emissions (HC, CO, NO_x, PM, and polycyclic aromatic hydrocarbons in PM) from a commercial DI diesel engine were measured for petroleum-derived fuels with a wide range of fuel properties. Fuel properties such as cetane number, aromatic content and type, and distillation temperature were independent of each other. The test results showed that PM and NO_x depended predominantly on aromatic content, especially polycyclic aromatic content, in fuel. PAH emission was also strongly affected by polycyclic aromatic content. The amount of sulfate in PM was proportional to sulfur content in fuel. The cetane number seldom affected the amount of PM and NO_x emissions.
