Hydrogen Engine Center Announces a 9.3L Compacted Graphite Iron Engine

ALGONA, IA - October 6, 2008: Hydrogen Engine Center, Inc. (HEC) (OTCBB: HYEG) announced today that it has entered into an agreement with Eliminator Performance Products to produce the largest spark ignited hydrogen V8 engine yet built. It is intended for large hydrogen-fueled electrical power generation systems and for buses. Ted Hollinger, HEC Founder, says, "This 572 cubic inch engine will give us a much needed power source. Hydrogen is very light and it takes a lot of displacement for every kW of power produced. Compacted Graphite Iron will increase the strength and life of the engine by more than five times and thus give very long engine life which is essential for engines running 24/7. This is our first Distributed Generation engine. After years of work I believe that HEC has an engine that can achieve the efficiency and durability that the industry has long been looking for. We are also proud to build this engine in the United States."

Michael Bowery states, “Eliminator Performance Products, Inc. is proud to manufacture the new 9.3L Oxx Power® block and cylinder heads designed for a wide variety of industrial applications. Eliminator will provide Hydrogen Engine Center, Inc. with 100% American made blocks and heads, which includes both castings and machining.”

He goes on to say, “Much of our success in the industrial segment has been taking ‘lessons learned’ from the performance industry, thus making an extremely stout product line. To date we have over 4000 industrial units operating accumulating almost 50 Million run-time hours. Durability and reliability are essential in both markets, therefore we are obligated to be abreast of any new technologies as they arrive.”

The new Oxx Power® blocks and heads will be Compacted Graphite Iron (CGI), a recipe based on current NASCAR blocks. Similarly, the 4-bolt main bearing caps and fasteners were designed after those found in top fuel dragsters. We believe the valley tray is undoubtedly the strongest in production, for any application. These are key attributes for Oxx Power® engine durability. The Oxx Power® block will have a priority oiling system promoting lubrication to the engines vital parts. Likewise, the block will be machined for a roller camshaft for high displacement without sacrificing reliability. HEC intends to develop a 10.2L engine based on the same engine technology.
