An air-vapor engine which exhibits one or more cylinders and a piston located therein, by which a stroke movement can be performed. Furthermore, the air-vapor engine has an injection nozzle and a prechamber. The prechamber is arranged between the injection nozzle and the cylinder, a fuel fluid is introduced into the prechamber from the injection nozzle. Compressed air from the cylinder can be received by the prechamber. This enables the stroke movement of the cylinder. In addition, the cylinder is connected to a condenser via an outlet valve such that the air-vapor mixture or the vapor of the air-vapor mixture condenses and is present in the condenser as condensate. The condenser and the injection nozzle are in flow connection. This means that the air-vapor engine exhibits a circuit, resulting in efficient operability.

A duel-fuel large diesel engine is proposed, comprising at least one cylinder having a combustion chamber, wherein a piston is arranged in the cylinder for a reciprocating movement between a top dead center position and a bottom dead center position, wherein the cylinder is provided with a first fuel injector (10) for injecting a first fuel into the combustion chamber, and a second fuel injector (20) for injecting a second fuel into the combustion chamber, wherein the first fuel is different from the second fuel, the large diesel engine further comprising a first fuel supply system (5) for supplying the first fuel to the cylinder and a second fuel supply system (7) for supplying the second fuel to a fuel distribution system (6), wherein the fuel distribution system (6) is configured to deliver the second fuel from the second fuel supply system (7) to the second fuel injector (20). A purge line (9) is provided connecting the first fuel supply system (5) to the fuel distribution system (6), wherein a switching member (8) is provided for opening and closing a flow connection through the purge line (9). Furthermore, a method for operating such an engine is proposed.
