The U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy’s Bioenergy Technologies Office has released a Request for Information (RFI) seeking stakeholder input on the following topics related to the use of advanced biofuel blends in small engines:

• The potential to optimize and/or modify small engines to utilize ethanol blends greater than 10% (E10)
• Technical hurdles of designing, developing, and/or modifying small, internal combustion engines to improve compatibility when operated with high-octane biofuel blends
• The market impact of increasing the consumption of biofuels in the small engine market
• Mechanisms for addressing the technical and non-technical hurdles of using biofuels in small engines.

The small engines of interest for this specific RFI are spark-ignition, internal combustion engines such as those found in small tractors, chainsaws, hand-held line trimmers, off-road motorcycles, generator sets, personal water craft, snowmobiles, and all-terrain vehicles. 

To see the full RFI, visit the EERE Exchange website. Responses must be submitted no later than 5:00 p.m. (EDT) on August 30, 2015.
