Bank of the curved cylinder creates a large displacement per housing volume.

FIGS. 8, 9 and 10 represent a modification of the machine tOa. The cylinder 29a has two oddly offset sections 115 and 116, in which the pistons 36a and 37a are slidably arranged. The connecting rods 78 and 83 run in the center plane of the respective piston (Pig · 9).

FIG. 15 shows a further modification. BIe connecting rods and 83 are arranged on the crankshaft 62 so that the piston 36 is at its top dead center when the piston 37 is has reached bottom dead center and vice versa.
