Abstract (en)
In order to increase the volumetric efficiency of piston-type internal-combustion engines, a cylinder/piston torque of annular preferably circular, cross section, is provided for. In one four-stroke form, the value arrangement comprises several values (10, 11) arranged in a circle around one central value (14) concentric with the engine cylinder (2). The two-stroke versions comprise crank-case scavenging with different slot arrangement in the inner resp. outer cylinder wall (103, 2).
