Reciprocating piston engine with crankshaft bearing offset to the side relative to vertical cylinder extension, to reduce side forces acting on piston during working stroke

摘要

The engine has a crankshaft bearing, which is offset outside of a vertical extension of the cylinder axis, so that during a working stroke, lower side forces act on the piston than with central positioning. To achieve a better torque, vertical excursion of the connecting rod outside the vertical extension is smaller during the working stroke than during the compression stroke.
