Abstract
A reciprocating-piston internal combustion engine includes first, second, and third cylinders, and a crank drive having a crankshaft rotatably mounted in a crank housing. The crankshaft has first and second crank pins, wherein a first and a second connecting rod for a first and a second piston are assigned to the first crank pin, and a third connecting rod for a third piston is assigned to the second crank pin. The first and the second cylinder together with the first and the second piston are arranged in a V-shape, wherein the third cylinder together with the third piston is arranged in the V.
