Sonex Research, Inc.

Sonex Research, Inc. develops and commercializes Sonex Combustion System (SCS), which improves the combustion of fuel in internal combustion engines for use in military and commercial applications. The SCS technology enables the combustion of fuels in engines through design modification of the pistons in four stroke, direct injected engines, and the cylinder heads in two stroke, spark ignited, and gasoline engines to achieve chemical/turbulent combustion. The company also develops Sonex controlled auto ignition combustion piston to the automotive industry, which allows ignition and combustion of low cetane heavy fuels by controlled auto-ignition at moderate compression ratios, and operates at controlled peak cylinder pressures; low soot diesel design that enables soot and oxides of nitrogen (NOx) reductions in standard DI diesel engines; gasoline direct injection engines; and Sonex two-stroke heavy fuel engine technology products for use in unmanned aerial vehicles, all-terrain vehicles, pumps, outboard engines, small watercraft, and generator sets. The company was incorporated in 1980 and is based in Annapolis, Maryland.
