EPA Certifies CleanFUEL USA's Latest Propane Engine System

GEORGETOWN, TX, Apr 06 (MARKET WIRE) --
Today CleanFUEL USA, a leading supplier of alternative fuel
infrastructure and propane engine systems, announced EPA certification of
the industry's first liquid propane engine built on a General Motors (GM)
6.0L chassis. Designed for OEMs to produce new light-duty vehicles that
operate on propane, CleanFUEL's liquid propane injection (LPI) system
provides a high-performance, fuel-efficient alternative to gasoline and
diesel engines to help fleets significantly reduce carbon emissions.
Propane is a domestically abundant, cost-competitive and cleaner-burning
fuel and is ideal for fleet transportation markets.

Sales of alternative fuel vehicles, including plug-in hybrid electric,
mild hybrid 1, natural gas and propane (also known as Autogas and
liquefied petroleum gas/LPG), and fuel cell powered vehicles are expected
to increase to 49 percent by 2035, up 36 percent from 2008 based on the
Annual Energy Outlook 2010 report released by the U.S Energy Information
Administration (EIA). About 13 million cars and trucks worldwide are
powered by propane today, and it is gaining popularity as a
transportation fuel because of its cost -- roughly 40-50 percent less
than gasoline/diesel per gallon -- and its environmental benefits.

CleanFUEL's advanced propane engine utilizes the patented Icom JTG
Technology and System manufactured by Icom North America and offers the
same horsepower, torque and performance as gasoline-powered engines. Yet
it produces 87 percent less hydrocarbons and 50 percent fewer toxins than
gasoline. CleanFUEL's system performed 25 percent better than comparable
gasoline and diesel engines tested against current EPA standards, also
reporting zero in particulate matter emissions rate. With the EPA setting
stricter fuel efficiency standards, new engine technologies, such as
CleanFUEL's LPI system offers vehicle manufacturers a viable and
cleaner-burning alternative for light-duty fleet vehicles, including
passenger vans, shuttle buses, walk-in vans and utility and service
vehicles.

"As the leader in the Type-A (small) school bus industry, it's essential
to deliver innovative products that meet our customers' demand for clean
fuel alternative vehicles," said Kent Tyler, President of Collins Bus
Corporation. "We are excited to partner with leaders in the propane
industry, such as CleanFUEL USA and PERC (Propane Education & Research
Council) to expand fleet options for school districts evaluating greener
modes of transportation to take advantage of federal tax incentives."

Collins will display its propane school bus test vehicle, featuring
CleanFUEL's new EPA certified 6.0L LPI system, April 9-12, 2010 at the
Southeastern Convention & International Propane Expo. The engine is
undergoing CARB testing and CleanFUEL expects the engine to be fully
certified and commercially available by summer of 2010.
