Advanced Engine Technologies Reports Testing Of a Turbocharged Version of The OX2 Engine

LOS ANGELES, Aug. 5 - Advanced Engine Technologies, Inc. today announced that, following the successful test results of its normally aspirated OX2 internal combustion engine, it has initiated preliminary testing of a turbocharged version of the OX2 powerplant and the test results are positive. AET's OX2, design level two, engine #2, generating 145 KPA of boost, created 215 lb ft of torque, resulting in 30 horsepower at 735 rpm, an increase of 80 lb ft of torque and 13.2 horsepower over its previously tested normally aspirated version. The turbocharged OX2 engine ran smoothly and was considerably quieter than under normally aspirated conditions.

"This latest testing, with the small compact turbocharger attached, has given us tremendous insight into the OX2's potential performance capabilities under turbocharged conditions," says Carroll Shelby, President, Advanced Engine Technologies. "We are very encouraged and excited about this new turbo OX2 performance milestone. However, we will continue to aggressively advance the performance and durability testing of the OX2 engine under normally aspirated conditions."

The OX2 turbocharged engine, fitted with a Motec fuel system, was test mapped in increments. At startup, the turbocharged test engine initially achieved 120 KPA of boost, which was then advanced to 135 KPA of boost and finally, with boost increased to 145 KPA and placed under a load, it demonstrated the positive and encouraging increased performance numbers and reduced noise levels. AET plans to continue its upmapping test sequence on subsequent OX2 test engines.

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 125 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. In addition, with 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 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.
