Standard diesel fuel (sometimes called diesel oil) comes in two
grades: Diesel-1 (D1) and Diesel-2 (D2). Diesel or Diesel fuel in
general is any fuel used in diesel engines. Thats why its also
commonly called as AGO or Automotive Gas Oil. Diesel fuel is a type
of fuel derived from the distillation of oil that is heavier than
gasoline but lighter than engine oil and heavy oil.
D1 is similar to kerosene and is lighter than D2. While D2 is sold
most of the time, D1 is sold during winter in very cold climates
and not sold in hot weather countries. But D2 is easily available
in most countries around the world. Despite rising awareness of
environmental protection, D2 remains to be a key type of fuel for
use in vehicles in many countries.
particular, demand for D2 has risen significantly in Asia over the
past years as a consequence of increasing number of cars. In view
of the country sustained economic growth, D2 will continue to be
undersupply in the China/India and market.
DIESEL EN590 ?
describes the physical properties that all automotive diesel fuel
must meet if it is to be sold in the European Union and Britain.
Automotive diesel has national variants but the usual variants
traded are EN590 and EN560 which are specified by ISO in Paris.
for diesel (in Europe) has been around for almost 20 years. However
fuel, like most products, is subject to a process of continuous
development and that development includes responding to
legislation. The EN590 standard has been amended many times since
590 had been introduced along with the European emission standards.
With each of its revisions the EN 590 had been adapted to lower the
sulphur content of diesel fuel. Since 2007 this is called ultra low
sulphur diesel as the former function of sulphur as a lubricant is
absent (and needs to be replaced by additives).
quality of European diesel fuels is specified by the EN 590
standard. While these specifications not are mandatory, they are
observed by all fuel suppliers in Europe. Automobile diesel EN 590
is intended for application in diesel engines. Diesel motor fuel
quality meets the requirements of European Standard EN 590.
operation in the conditions of a temperate climate following marks
of fuel diesel automobile EN 590 are offered: Grade C limiting
filterability temperature -5 ° C; Grade D limiting filterability
temperature -10 ° C; Grade E limiting filterability temperature 15
° C; Grade F limiting filterability temperature -20 ° C.
entire volume of produced diesel fuel quality meets the
requirements for fuels for vehicles of Euro 4 and Euro 5. Low
sulfur content in diesel EN 590 reduces emissions of sulfur oxides
into the atmosphere, which is especially important for for
inhabitants of big cities.
of the important revisions of the EN 590 standard have been:
590:1993 the first EU diesel fuel specification. It established a
sulphur limit of 0.2% in on-road and non-road diesel fuels.
590:1999 this standard reflected the sulphur (350ppm) and cetane
(51) specifications by Directive 98/70/EC.
590:2004 Sulphur limits of 50ppm (Euro 4) and 10ppm (Euro 5) as
regulated by Directive 2003/17/EC. FAME (Fatty Acid Methyl Ester)
content of 5% (B5)
590:2009 FAME content of 7% (B7) as regulated by Directive
2009/30/EC. This directive also adopts mandatory biofuel
requirements for refiners and introduces a 10ppm sulphur limit in
non-road fuels effective 2011.
WHAT IS ULTRA
LOW SULPHUR DIESEL (ULSD) ?
Low Sulfur Diesel (ULSD) is diesel fuel with substantially lowered
sulfur content. As of 2006, almost all of the petroleum-based
diesel fuel available in Europe and North America is of a ULSD
is not a single standard set of specifications and as the
government mandated standard becomes progressively more strict so
does the definition. The move to lower sulfur content is expected
to allow the application of newer emissions control technologies
that should substantially lower emissions of particulate matter
from diesel engines.
change occurred first in the European Union and is now happening in
North America. New emissions standards, dependent on the cleaner
fuel, have been in effect for automobiles in the United States
since model year 2007.
has a lower energy content due to the heavy processing required to
remove large amounts of sulfur from oil, leading to lower fuel
economy. Using it requires more costly oil.
