Sowda® Engines and Compressors offers patent use and building licensing rights to a new, innovative, one-of-a-kind mechanism that maximizes power extraction to automotive and industrial engine and machine manufacturers. The Sowda® mechanism is a 45-year-long effort that combines my work (Sokalski) with all of the positive benefits of the ingenious works of Nikolaus August Otto, Felix Wankel, Rudolf Diesel, and James Atkinson in one working and proven apparatus, hence the name Sowda®. See photos of the working model.

About My Invention

The Sowda® Engine mechanism provides the most fuel efficient engine in the world. The high efficiency is accomplished by providing an infinitely variable compression ratio applicable to both 2-cycle and 4-cycle engines. With the infinitely variable compression ratio, the engine can automatically adjust the top dead center height of the piston so as to maintain a constant pressure ignition (CPI). Emission are dramatically reduced. Additionally, the 4-cycle engines have two distinct stroke lengths: short intake/compression strokes and longer power/exhaust strokes so as to extract maximum power. Typically, the power/exhaust strokes are 40% longer than the intake/compression strokes. Exhaust temperatures are dramatically reduced as more power is extracted.

Mission Statement

Make the Sowda® patent use and build licensing rights available to all automotive and industrial manufacturers and hopefully each manufacturers will improve upon the design to the point where every new internal combustion engine in the world contains the Sowda® mechanism.
