Title:
FUEL OIL COMPOSITION FOR DIESEL ENGINE
Document Type and Number:
Japanese Patent JP2004225000
Kind Code:
A
Abstract:
To provide a fuel oil composition for diesel engines generating few environmental pollutant due to combustion of the fuel oil, and highly stable to a rubber such as NBR used for a sealing material or the like of a jet pump in the diesel engine.
This fuel oil composition for diesel engines has a stability index of ≥26, which is defined by formula (I): Stability Index=Aro(vol%)+5×MAro(vol%)+AO(ppm)-N(ppm), wherein Aro(vol%) is the content(vol%) of a monocyclic aromatic component, MAro(vol%) is the content(vol%) of a polycyclic aromatic component, AO(ppm) is the content(mass ppm) of an antioxidant and N(ppm) is the content(mass ppm) of a nitrogen component(mass ppm, excluding one derived from the antioxidant).
