TAMPA, Fla.--(BUSINESS WIRE)--Feb. 1, 2006--Hybrid Fuel Systems, Inc., ("Hybrid" or the Company") (OTCBB: HYFS) today announced the receipt of the US Environmental Protection Agency (EPA) Conversion System Certificate of Conformity for the Company's patent dual-fuel diesel conversion system. The Certificate of Conformity was declared effective January 19, 2006.

Applicable to the Company's dual-fuel diesel system installed on Mack engine families, the Certificate of Conformity allows Hybrid to now pursue domestic conversion opportunities primarily in the refuse hauling segment of the US market place. "We are pleased with this official Certificate for several reasons," stated Hybrid CEO Mark Clancy. "While we have had some success with certifying our portfolio of gasoline systems, adding our first dual-fuel diesel Certificate opens several new marketing channels. We also believe that our dual-fuel diesel Certificate is the first for a small volume manufacturer in the US aftermarket and can aid in differentiating our technology and our Company," concluded Mr. Clancy.

Sheri Vanhooser, the Company's Vice President Business Development said, "As a Company we are proud to lead the way in demonstrating that the technology exists today to bring diesel vehicles into compliance with current emission standards. Working through our development facility in Atlanta, we now anticipate adding several more diesel engine platforms to our portfolio of certified systems in the coming year," concluded Ms. Vanhooser.
