SONEX COMBUSTION PROCESSES

Sonex Research, Inc., a small business located in Annapolis, Maryland, is developing and commercializing a patented proprietary technology, known as the Sonex Combustion System (SCS), which improves the combustion of fuel in internal combustion engines.  The SCS achieves in-cylinder control of ignition and combustion through chemical/turbulent enhancement using patented combustion chamber designs.  The SCS combustion chamber is defined by embodiments located in the piston in four-stroke direct injected engines and in the cylinder head in two-stroke spark-ignited (SI) engines.  SCS designs reduce fuel consumption and emissions, and permit adapted gasoline engines to run on safer diesel-type, kerosene-based, “heavy fuels” in military and commercial applications requiring lightweight engines and safe handling/storage of fuel, such as in unmanned aerial vehicles (UAVs). 
 

Our multi-fuel, lean burn Sonex Controlled Auto Ignition (SCAI) piston based technology in four-stroke Direct Injected (DI) engines achieves:

• Low NOx, CO, HC and particulates
• 25% greater fuel efficiency (than gasoline) at moderate compression ratio (<12.5:1) with peak cylinder pressure  <100 bar
• Feasibility established for next generation GDI engine

Our piston based Low Soot Diesel Design (LSDD) in four-stroke DI engines achieves:

• Particulate reduction up to 70%, even with EGR with no fuel penalty

Our two-stroke modified cylinder head and cold starting Heavy Fuel Engine (HFE) technology achieves:

• 25% lower fuel consumption (than gasoline) at 8:1 compression ratio
• Spark Ignited, carbureted (or fuel injected)
• Cold start at -20 degrees C in < 2 minutes

Sonex is seeking partners to fully develop its engine technology.  Licensing opportunities are available.
