Cummins Inc. has announced the approval of biodiesel B20 blends for use in its 2002 and later emissions-compliant ISX, ISM, ISL, ISC and ISB engines. This includes the recently released 2007 products.
Cummins is able to upgrade its previous position on the use of biodiesel fuel, which limited the use to B5 blends only, up to B20 for three key reasons. First, the American Society of Testing Materials specification ASTM D6751 now includes an important stability specification for B100 biodiesel.
Second, the availability of quality fuels from BQ-9000 Certified Marketers and Accredited Producers is rapidly growing.
Third, Cummins has completed the necessary testing and evaluations to ensure that customers can reliably operate their equipment with confidence using B20 fuel.
The popularity and use of biodiesel fuel continues to climb. Recent studies predict that, by 2008, 1.2 billion gallons of B100 biodiesel will be produced in the United States.
Blends above 5 percent generally are not approved by most of the engine manufacturers, but some such as Caterpillar are exceptions. Some blends up to B30, if they meet certain very specific standards, have been approved.
Further information about the use of biodiesel for both on-highway and off-highway Cummins products can be found on the Web at Cummin’s website.
