Influence of Density and Viscosity of Diesel Fuel on Exhaust Emissions 2003-01-1869

Fuels of wide range of density and viscosity were tested by using a DI diesel engine that conforms to present Japanese regulations. A total of 9 fuels was tested. Six test fuels were commercial automotive diesel fuel available in Japan. In order to expand the density range, test fuels of kerosene, high-density diesel fuel and automotive diesel fuel in Singapore were also included. The density range was 0.796 to 0.856 (g/cm3), and the viscosity range was 1.52 to 5.44 (mm2/s). The test mode was Japanese D13. Also, some fuels were tested by the Japanese transient test mode. Moreover, fuel spray was observed by an optical method to clarify the relationship between viscosity and Sauter mean diameter.
