摘要： A combustion engine. The engine includes an engine housing; at least one cylinder disposed in the engine housing; and a crank drive including: a crankshaft having a crank; and a piston being axially displaceable within the cylinder. The crank drive further includes a connecting rod which has an upper connecting rod part hinged to the piston; and a lower connecting rod part hinged to the crank. The lower connecting rod part is hinged to the upper connecting rod part. A central joint hinges the upper connecting rod part and the lower connecting rod part to one another, a longitudinal axis of the upper connecting rod part further being defined by a line connecting the central joint with a hinge joint of the upper connecting rod part to the piston. The engine further includes a hinge point disposed on the engine housing; a control arm hinged at one end thereof to the hinge point, and at another end thereof to the upper connecting rod part; an additional joint for hinging the control arm and the upper connecting rod part to one another disposed adjacent the central joint at a distance from the longitudinal axis of the upper connecting rod part; and a controllable adjusting device connected to the hinge point for changing a distance of the hinge point with respect to the cylinder axis.
