Fuel Effects on Emissions from Diesel Vehicles Equipped with Advanced Aftertreatment Devices 2005-01-3700

Exhaust emissions from diesel vehicles equipped with advanced emission reduction technologies including the most up-to-date aftertreatment devices were examined from the viewpoint of fuel properties effects.
Three kinds of diesel trucks with different emission levels were used:
  • Vehicle A: compliant to the Japanese Long Term Regulation (J-1998 Regulation)
  • Vehicle B: compliant to the Japanese New Short Term Regulation (J-2003 Regulation)
  • Vehicle C: compliant to the J-2003 Regulation with NOx and PM emissions lowered by 75% and 85%, respectively, from the emissions standard values.
Eight kinds of test fuels were used with their characteristics changed parametrically in distillation ranges, aromatics contents and sulfur content. Among them were those conforming to the Category-4 Specifications of the World Wide Fuel Charter (WWFC).
Emissions of PM, NOx, THC, NMHC, CO and CO2 and fuel economy were examined.
