Cat Approves B20 For Smaller Diesels

Posted on September 16, 2008

Caterpillar has approved the use of B20 biodiesel across its range of compact and mid-range engines including the C0.5 through C2.2 Tier 4 Interim (11 to 66 hp), the C4.4, C4.4 ACERT and C6.6 ACERT (72-275 hp) Tier 3/Stage IIIA compliant engines.

“These engines join the previously B30 approved C7 ACERT through C32 ACERT and our 3400 and 3500 series,” said Cat industrial engine marketing manager Mike Reinhart.

The addition of these engines to the B20 approved product line follows successful testing of higher percentage blended fuels in a number of installations, Cat said. Biodiesel used in B20 blends must meet the most current version of ASTM D6751 or EN14214. The final B20 blend should meet the minimum requirements of the upcoming ASTM specification for B5-B20 blends.
