  ITEM 5. - OTHER EVENTS AND REGULATION FD DISCLOSURE
  
  
  On July 19, 2004, the Registrant issued the following  announcement over the
  newswire and posted it on its website (www.sonexresearch.com):
  
  
                  SONEX RECEIVES $192,932 FOLLOW-ON TASK FROM DARPA
  
  
  ANNAPOLIS,  MARYLAND,  July 19, 2004 - SONEX  RESEARCH,  INC. (OTC BB: SONX),  a
  leader in the field of clean burn combustion  technology,  announced that it has
  received a $192,932  follow-on task from the Defense Advanced  Research Projects
  Agency (DARPA) to continue  development of a multi-cylinder  "heavy fuel" engine
  (HFE) combustion process for potential  Department of Defense (DoD) applications
  such as unmanned aerial vehicles (UAVs).
  
  Under the existing contract, Sonex has adapted a lightweight gasoline automotive
  engine to an unthrottled,  direct fuel injection combustion process based on the
  Sonex  Controlled  Auto-Ignition  (SCAI)  technology  to  run on  JP5,  military
  kerosene-based  heavy fuel. The SCAI process is enabled by a proprietary  piston
  technology that achieves in-cylinder chemical kinetics at a moderate compression
  ratio for auto ignition of the JP5. Sonex adapted the automotive gasoline engine
  using a computer aided design and prototyping  fabrication process that involved
  subcontractors  and  specialty  suppliers.   The  laboratory  HFE  features  the
  proprietary Sonex pistons,  electronically controlled common rail fuel injection
  system and extensive instrumentation.
  
  The  contract  was  extended to add a task to:  enhance the  6-cylinder  HFE for
  higher power output; achieve boosted HFE combustion  optimization;  perform data
  collection-analyses; and provide a technical readiness demonstration. Sonex will
  determine the technical  feasibility of turbo-charging  the HFE for higher power
  output and advantageous rates of fuel consumption.
  
  This project is sponsored by DARPA as a technology feasibility  demonstration of
  a means for  lightweight  piston  engines to comply with a DoD policy  directive
  that mandates kerosene-based "heavy" fuel for all engines.  Gasoline engines are
  typically 25% to 30% lighter than diesel engines; thus, fully qualified, adapted
  gasoline engine designs that could burn low cetane (hard to ignite, diesel type)
  heavy fuel would address DoD performance, logistics and safety requirements.

  About DARPA
  
  The Defense  Advanced  Research  Projects Agency (DARPA) is the central research
  and development organization for the Department of Defense (DoD). It manages and
  directs  selected basic and applied  research and development  projects for DoD,
  and pursues research and technology where risk and payoff are both very high and
  where success may provide dramatic  advances for traditional  military roles and
  missions.  More  information  about  DARPA  can  be  found  on the  Internet  at
  www.darpa.mil.
  
  
  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.  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).
  
  
  Caution Regarding Forward-Looking Statements
  
  "Forward-looking"  statements  contained  in this  announcement,  as well as all
  publicly disseminated material about the Company, are made pursuant to the "safe
  harbor" provisions of the Private Securities Litigation Act. Such statements are
  based  on  current  expectations,  estimates,  projections  and  assumptions  by
  management  with respect to matters  such as  commercial  acceptance  of the SCS
  technology, the impact of competition,  and the Company's financial condition or
  results of  operations.  Readers  are  cautioned  that such  statements  are not
  guarantees of future  performance and involve risks and uncertainties that could
  cause  actual  results to differ  materially  from those  expressed  in any such
  forward-looking statements.  Additional information regarding the risks faced by
  Sonex is provided in the  Company's  periodic  filings with the  Securities  and
  Exchange Commission under the heading "Risk Factors". Such filings are available
