Cummins Inc. has approved B20 biodiesel
blend for use with its 19- to 78-liter highhorsepower
engine platforms manufactured
after January 1, 2008. This approval,
according to the company, provides a significant
expansion of Cummins engine compatibility
with B20 usage, bringing the environmental
benefits of using a 20% renewable
fuel blend to high-horsepower applications
in mining, industrial and power generation
markets. Cummins high-horsepower
engines approved for use with B20 biodiesel
include the Quantum Series engine
platforms from the QSK19 to the QSK78,
covering a 506- to 3,500-hp range (377 to
2,610 kW). Cummins K Series engine platforms
from the K19 to the K2000E are also
approved for use with B20 biodiesel across
a 450- to 2,000-hp range (336 to 1,491
kW). These high-horsepower engines will
join Cummins EPA Tier 3 and EU Stage IIIA
industrial engines already B20-approved
down to the 80-hp (60 kW) QSB3.3.
Cummins requires that biodiesel fuel blends
above B5 and up to B20 used in all
Cummins engines to be purchased from
BQ-9000-certified suppliers and meet both
the revised ASTM D6751 and the new
ASTM D7467 standards or equivalent international
specifications.
Cummins is participating in industry
efforts aimed to improve the consistent
quality of biodiesel. The availability of
biodiesel from BQ-9000 Accredited Producers
and Certified Marketers has
increased significantly. Working closely
with the American Society of Testing
Materials has resulted in an improved
B100 specification (ASTM D6751) that
now requires a cold soak test and a new
B20 specification (ASTM D7467) that
includes an oxidation stability requirement.
