SAN MARCOS, Calif., July 29, 2008 (PRIME NEWSWIRE) -- Omnitek Engineering, Corp. (Other OTC:OMTK.PK - News) reports the receipt of Notice of Allowance from the United States Patent Office for a key technology, essential for achieving ultra-low emission levels with natural gas engines.

The Omnitek Fuel Mixing Apparatus has been applied on engines of various sizes with expected superior results. One engine equipped with this technology has already received EPA and CARB emission certifications.

The technology greatly improves air/gas mixture formation. The resulting complete combustion greatly reduces emissions and increases fuel economy.

Omnitek plans to make this technology available to other engine manufacturers, such as Cummins, Volvo, Isuzu and Mercedes, in an effort to support the fight to lower air pollution and combat global warming.

About Omnitek Engineering, Corp. (Other OTC:OMTK.PK - News)

Omnitek Engineering, Corp. develops and sells new natural gas engines, as well as a proprietary diesel-to-natural gas conversion system, which has established Omnitek as a leader in the industry.

Omnitek offers a total system approach and is dedicated to supplying alternative energy and emissions control solutions that are sustainable, affordable and contribute to combat global warming. As the price of crude oil continues to increase and the threat of global warming and air pollution remains, the search for an alternative fuel becomes increasingly important. Natural gas has emerged as a perfect solution to these challenges. Readily available in many countries from indigenous sources, natural gas is inexpensive and clean burning.

Diesel engines have been the backbone of the transportation industry. Valued for their power, fuel economy and durability, diesel powered trucks and buses are used worldwide, however, they are heavy polluters and significantly contribute to global warming. Omnitek has developed a system to convert any existing diesel engine to a clean-burning natural gas engine at a fraction of the cost of a new engine.

Omnitek estimates the population of heavy-duty diesel vehicles and stationary engines around the world which can be converted using the Omnitek Diesel-to-Natural Gas Conversion System and offer the best ROI approaching ten million engines.

Prevailing economic factors, rising oil prices and the real threat of global warming make abundantly available and inexpensive natural gas the fuel for the future.
