Advanced Engine Technologies Inc. Board of Directors Pass Resolution to File a Form 15 LOS ANGELES, April 1 /PRNewswire-FirstCall/ -- Advanced Engine Technologies Inc. (OTC:AENG) (BULLETIN BOARD: AENG) announced that on February 17, 2005, Advanced Engine Technologies, Inc. Board of Directors RESOLVED, that AET will de-register the company's stock with the SEC through the filing of a Form 15 with the SEC so as to suspend its reporting obligations under the Securities Exchange Act of 1934, subject to the fulfillment of conditions precedent. In doing so, the Board noted that the satisfaction of these conditions precedent (which include issuance of a press release and subsequent Board action) may take approximately ninety (90) days to complete before the filing of the Form 15 can be accomplished. The OX2 is a 4-stroke, 1.1-liter internal combustion engine that is 17 inches in diameter with a length of 13 inches and a total weight of 179 pounds in normally aspirated form. The compact engine weighs 75 percent less than and is half the size of traditional internal combustion engines. In addition, it offers the flexibility of being able to run on a variety of fossil fuels including gasoline, diesel, natural gas, liquid propane or methane. Containing far fewer moving parts than traditional engine designs, the OX2 engine could offer the further advantages of significantly enhanced operation and maintenance costs and a longer useful life. With its expected higher power-to-weight ratio, multi-fuel capacity and anticipated low emissions and high fuel efficiency, the OX2 has a practical and much needed application in the commercial and industrial generator markets. Additional future applications may include marine, light-duty farm and construction equipment, light aircraft, and the hybrid electric vehicle market. However, the near term focus remains electrical generator applications. Investor inquiries can be directed to the company at (310) 914-9599.
