Gevo Supplied Isobutanol-Gasoline Blend Runs Well in Small Engines
October 28 2011 - 7:45AM
Business Wire
In side by side performance, durability and emissions testing of
small engines, gasoline blended with isobutanol performed better
than blends using ethanol. Gevo, Inc. (NASDAQ: GEVO), a renewable
chemicals and advanced biofuels company, provided the isobutanol to
the Outdoor Power Equipment Institute (OPEI) and Briggs &
Stratton (B&S), who tested both fuel blends in B&S small
engines. The results demonstrated that unlike ethanol, blends
incorporating isobutanol do not cause any irregular or unstable
engine or performance issues. The outcome suggests that isobutanol
blends at 12.5% could ease the pressure on moving to higher ethanol
blends to meet biofuel mandates with no impact on small engines.
Isobutanol is a drop-in fuel that requires no flex fuel engines,
special blender pumps or pipelines.
"Briggs & Stratton is encouraged by the results of the
isobutanol testing on our engines,” said Todd Teske, Chairman,
President & CEO of Briggs & Stratton Corporation. "We are
very interested in alternative fuels that do not cause damage to
the substantial number of engines in use today while lessening
the country's dependency on foreign oil."
“The OPEI test results provide further evidence that isobutanol
is a superior gasoline blend stock for engines of all kinds,” said
Patrick Gruber, Ph.D., CEO of Gevo. “In addition to the issue of
engine compatibility, our technology addresses other limitations of
ethanol – infrastructure compatibility, evaporative emissions and
the blend wall – to the benefits of all consumers. Isobutanol
eliminates barriers across the fuels value chain and provides a
very significant opportunity for growth in biofuel use for small
engines and for automobiles.”
“These results show us that isobutanol could be a biofuel
alternative that can be introduced into the existing supply chain
without the potential for disruption and harm to our outdoor power
equipment engines,” said Kris Kiser, President and CEO of OPEI. “In
the economic interest of our members and the safety interest of
consumers, we need to be open to a biofuel that can perform
reliably in the millions of products on the market -- lawnmowers,
chainsaws, motorcycles, snowmobiles, ATVs and UTVs, boats and older
cars.”
Kris Kiser announced the results today at the industry’s largest
trade show, GIE + EXPO. After testing three different B&S
engine models on isobutanol, the following test results were
reported:
- No engine or performance issues were
found while running on an Isobutanol blend.
- Horsepower and torque levels remained
the same while running on Isobutanol.
- Equivalent or better performance than
E10 at temperatures ranging from 40°F to 120°F.
- No significant change in emissions
(HC+NOx) levels.
- Isobutanol does not absorb water like
ethanol. This will lead to fewer problems in the seasonal use
conditions and long storage periods that are common with small
engine applications.
