Improvements To OX2 Engine Porting Yield Gains In Horsepower And Torque
LOS ANGELES (April 21, 2003) - Advanced Engine Technologies Inc. (OTC
Bulletin Board: AENG) announced today that it has completed the first
phase of OX2 Engine port re-engineering. AET engineers have successfully
advanced the OX2 Engine's port shape and location from its earlier
design. Through engine modeling, Flow bench analysis, and eventual
real-time engine lab testing, AET engineers have been able to re-engineer
the intake and exhaust port\shape and location on Design Level 2, OX2
Engine #2. This re-engineering has resulted in a 40% improvement in
the OX2 engine's airflow or known as Volumetric Efficiency. This improvement
has also yielded a 16% improvement in torque from 135 to 157 ft lbs,
and a 23% increase in horsepower from 17 to 21 hp.
"This improvement in porting will now allow the OX2 to breathe
freely, and provide us with greater opportunities for performance improvements" says
Carroll Shelby, President, AET. "In addition, this new porting
configuration has increased the exhaust velocity by 400% this will
prove to be very valuable in future turbo applications."
AET has also started validation testing of its recently received Design
Level 2, OX2 Engine #4. Utilizing an increased bore and shorten stroke,
this design is expected to yield a marked improvement in overall engine
performance.
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.

the progress of the OX2 engine, Advanced Engine Technologies has established
