- the relaxation tion ie, the displacement of the piston from top dead center to bottom dead center extends, namely from 180 degrees to 220 to 225 degrees
- the compression stroke ie the displacement of the piston from bottom dead center to top dead center from 180 degrees to 135 degrees is shortened.
- the English patent application GB 2 053 352 A discloses a four-stroke engine in which two crankshafts are also used to drive the piston. These are coupled together in such a way that they rotate in a predetermined speed ratio of two to one relative to each other.
