Fundamental hardware differences between a 4-stroke piston and a Wankel rotary
  • The Rotor replaces the piston engine's piston.
  • The Eccentric Shaft replaces the piston engine's crankshaft and connecting rods.
  • The Rotor Housing replaces the piston engine's cylinder.
  • Intake and Exhaust Ports in the housings replace valves, camshafts, rocker arms, springs, lifter rods, and timing belts.

4 - Stroke Piston vs. 4 - Stroke Rotary


Ground Applications
The Wankel rotary engine principle Rotapower engine is a perfect alternative to nearly all 2-stroke engine applications and many of the high power-to-weight applications using conventional 4-stroke piston engines today.
