Cummins Inc. announced today that it is approving us of B20 blends of biodiesel for use in its Tier 3 emissions compliant QSB4.5, QSB6.7, QSC, QSL, QSM and QSX engines. These powerplants can be found in different late-model farm machines as well as in over-the-road trucks.
Cummins notes it was able to upgrade its previous position on the use of biodiesel fuel - previously only at the B5 level - to B20 for three reasons.
First, the American Society of Testing Materials specification ASTMD6751 now includes a stability specification for B100 biodiesel used in the blend.
Second, the availability of quality fuels from BQ 9000 Certified Marketers and Accredited Producers is growing rapidly.
Third, Cummins has completed the necessary testing and evaluations to ensure that customers can reliably operate their equipment with the B20 fuel.
The fuel buyer must be aware they are using fuel that meets ASTMD6751 specifications to take part in this enhanced biofuels program.
In a press statement, Edward Lyford Pike, chief engineer of Alternative Fuel Programs - Cummins, remarks: "We have completed an exhaustive analysis and test evaluation which enables Cummins to provide necessary guidance and information to our customers for the proper and successful use of this fuel in many of our engines."
The announcement points to recent studies showing that by 2008 1.2 billion gallons of B100 biodiesel will be produced in the United States. Cummins continues its testing to ensure future products as well as other industrial engines such as its A Series, B3.3, QSB3.3 and high-horsepower engines, will be compatible with biodiesel fuels.
