Wisconsin Motors to certify replacement for Ford 4.9L engine

ALGONA, Iowa (October 12, 2010) - Hydrogen Engine Center, Inc. ("HEC") (OTCPK: HYEG) announced today that HEC and Wisconsin Motors (WM) have signed an agreement to form Oxx Power Continental, a JV, to produce a wet sleeve version of the Oxx Power 4.9L six cylinder engine. The new engine will replace both the Ford F300 and the Oxx Power 4.9L engines in the industrial market. Wisconsin Motors intends to certify these engines on traditional fuels (gasoline, natural gas and propane) while HEC intends to use alternative fuels such as hydrogen, ammonia, syngas, ethanol and methanol.

The team will start testing the new engine this month and hope to introduce the new engine late in the fourth quarter. The new engines will be machined at V&L Tool in Wisconsin, assembled at Wisconsin Motors facility in Dyer, Tennessee. Alternative fuel systems and controls will be added at HEC. Alternative fuel electrical generator systems will be built at HEC in Algona, Iowa. The Dyer facility is almost a quarter million square feet and has five test cells for EPA emission certification. This frees up needed space in Algona to expand HEC's genset business.

"The demonstration of this engine will complete years of development work and will allow the sale of systems worldwide without concerns about having to ever replace the engine blocks." says Ted Hollinger, HEC President. Ted says he likes to think of the new engine as a "forever engine" because the engine block should never wear out.

Gerald (Gerry) Schaefer, president of Wisconsin Motors stated, "The opportunity to add a proven six cylinder engine to our product line is exciting. This will complete our product line and nicely complements the Wisconsin Motors offerings."

To get started WM picked up 206 engine blocks from HEC and took them to Wisconsin for machining. Two more similar loads will follow.
