Abstract

A reciprocating internal combustion engine includes a reciprocating piston in a cylinder bore of a cylinder housing forming an assembly together with a cylinder head. Two connecting rods are connected between the piston and first and second crankshafts. The two crankshafts are functionally connected to two synchronization gears of a spur gear box. The synchronization gears are connected to the crankshafts in a torque-proof manner such that the crankshafts rotate synchronously in opposite directions. The engine operates based on the diesel principle and with exhaust gas turbocharging, wherein the engine is an outboard engine for a watercraft. The exhaust gas turbocharger has an exhaust gas turbine and a compressor and/or a shaft which carries a turbine wheel and a compressor wheel which runs perpendicular to the longitudinal dimension of the watercraft. The turbocharger is attached on an upper end-face wall of the assembly.
