Cummins Inc. announced the approval of B20 biodiesel blend for use with 19- to 78-liter high-horsepower engine platforms manufactured after January 1, 2008. This provides a significant expansion of Cummins engine compatibility with B20 usage, bringing the use of a 20 percent renewable fuel blend to high-horsepower applications in mining, oil and gas, rail, industrial and power generation markets.
Engines approved include engine platforms from the QSK19 to the QSK78 cover a wide 506- to 3500-hp range (377 to 2610 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 1491 kW).
These high-horsepower engines will join Cummins EPA Tier 3 industrial engines already B20-approved down to the 80-hp QSB3.3 engine.
Cummins requires that biodiesel fuel blends above B5 and up to B20 used in all Cummins engines are purchased from BQ-9000-certified suppliers and meet both the revised ASTM D6751 and the new ASTM D7467 standards or equivalent international specifications.
