A coolant delivery device for an internal combustion engine, in particular for a motor vehicle, includes a pump, a an activatable electric motor, a shut-off valve, a return line, a heating device, and a common module housing. The pump is configured to deliver liquid coolant, and includes a suction port configured to connect to a tank, and a pressure port for the coolant and which is assigned to the engine. The motor is configured to drive the pump. The valve is assigned to the suction port. The return line is configured to connect to the tank, and includes at least one check valve. At least the pump, motor, valve, heating device, and the at least one check valve together form a delivery module and are positioned in the common module housing.

A ship propulsion system comprises at least one internal combustion engine with a combustion chamber for burning a fuel and a turbocharger with a compressor in an intake tract of the internal combustion engine. The ship propulsion system further comprises an electrolysis device, which produces hydrogen and oxygen gas, which are added on a pressure side of the compressor and conducted to the internal combustion engine. Moreover, a water tank and an alcohol tank are connected to a pressure side of the compressor in order to add water and alcohol to the charge air.
