About Sonex

Sonex  Research,  Inc.,  a leader  in the  field of  combustion  technology,  is
developing its patented Sonex Combustion  System (SCS)  piston-based  technology
for in-cylinder  control of ignition and  combustion,  designed to increase fuel
mileage and reduce  emissions  of internal  combustion  engines.  Sonex plans to
complete  development,  commercialize  and  market  its  Sonex  Controlled  Auto
Ignition (SCAI)  combustion  process to the automotive  industry to improve fuel
efficiency of gasoline powered vehicles in response to forthcoming  increases in
national vehicle fuel mileage standards.  Additionally,  independent third-party
testing has confirmed the potential of the SCS application  for  direct-injected
diesel  engines to reduce  harmful  soot  in-cylinder  without  increasing  fuel
consumption.  Other SCS  designs are being used to convert  gasoline  engines of
various sizes to operate on safer, diesel-type "heavy fuels" for use in military
and commercial applications requiring light weight and safe handling and storage
of fuel, such as in UAVs (unmanned aerial vehicles).
