American Technologies Group Announces the Approval and Sponsorship of the Force-R by Japan's Environmental Purification Association.

MONROVIA, Calif.--(BUSINESS WIRE)--Sept. 17, 1998--American Technologies Group, Inc. (OTC Bulletin Board: ATEG), announced today that the Environment Purification Association (EPA) of Japan has approved The Force(R), ATG's proprietary airborne combustion-enhancement product, to help reduce pollutants from automobiles and trucks. This move is part of the Japanese EPA's response to the recent request by the Japanese Ministry of Transportation for assistance in red ucing environmental pollutants.

The EPA has begun their official sponsorship of the additive by purchasing samples of the product which they are distributing to vehicle maintenance providers in Japan as part of a program to educate and familiarize professional maintenance and repair facilities with The Force(R) product. The EPA recommends product implementation and monitors government-approved programs for all vehicles.

The Japan Automotive Technology Association, an official Japanese testing facility, recently tested The Force(R) for its ability to reduce emissions. The results of these tests showed a 32.6 percent reduction in the emission of carbon monoxide (CO), a 14.7 percent reduction in the emission of hydrocarbons and a seven percent reduction in the emission of nitrogen oxide (NOx), all three of which are environmentally damaging pollutants.

The Force(R) is a catalyst which is placed into the vehicle's air intake system, where it mixes with the air/fuel mixture. It is an environmentally benign combustion enhancer, not a "normal" metal-based catalyst or a petroleum-based detergent additive. It contains no halogens, aromatic solvents or other environmentally hazardous components and has been demonstrated as effective in improving performance of both gasoline and diesel engines.

Lawrence J. Brady, chairman and CEO of ATG said, "I am honored to have ATG's Force(R) product recommended by the Environment Protection Association of Japan. Recognition by such a prestigious and powerful organization is added validation of our technology and its utility and significance to cleaning up the environment. This is only our first step in penetrating the Japanese market."
