Title:
GAS OIL COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2007/114025
Kind Code:
A1
Abstract:
This invention provides a gas oil composition for use in superchargers having
a geometric compression ratio of not more than 16 and diesel engines with EGR.
The gas oil composition is an FT synthetic base material-containing gas oil composition
for a summer or winter season suitable for both diesel combustion and premixing
compression ignition combustion. The gas oil composition has a sulfur content
of not more than 5 ppm by mass, an oxygen content of not more than 100 ppm by mass,
a volume modulus of not less than 1250 MPa and not more than 1450 MPa, a saybolt color
of not less than +22, a lubricating property value of not more than 400 μm,
and distillation characteristics of 140°C or above for the initial boiling
point and 380°C or below for the end point, and is characterized in that (1)
the cetane number in a fraction range below 200°C is not less than 40 and less
than 60, (2) the cetane number in a fraction range of 200°C or above and below
280°C is not less than 60 and less than 80, and (3) the cetane number in a fraction
range of 280°C or above is not less than 50.
