Abstract
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.

A retrofitting method for a ship propulsion system, wherein the ship propulsion system comprises at least one internal combustion engine with:
- a combustion chamber for burning a fuel;
- an intake tract for supplying fresh air to the combustion chamber;
- and
- a turbocharger with a compressor in the intake tract;
- the method comprising:
- connecting an electrolysis device configured to produce hydrogen and oxygen gas to a pressure side of the compressor for supplying hydrogen and oxygen gas into the intake tract;
- and
- connecting a water tank and an alcohol tank to a pressure side of the compressor for supplying water and alcohol into the intake tract.
A ship propulsion system comprising:
- at least one internal combustion engine with:
- a combustion chamber for burning a fuel;
- an intake tract for supplying fresh air to the combustion chamber;
- and
- a turbocharger with a compressor in the intake tract;
- an electrolysis device for producing hydrogen and oxygen gas for the internal combustion engine;
- and
- an alcohol tank for supplying alcohols to the internal combustion engine;
- a water tank;
- wherein the water tank and the alcohol tank are connected to a pressure side of the compressor for the supply of water and alcohol into the intake tract, and
- wherein the electrolysis device is connected to the pressure side of the compressor for supplying hydrogen and oxygen gas into the intake tract.
A method for operating a ship propulsion system, comprising the following steps:
- burning a fuel in a combustion chamber of an internal combustion engine;
- supplying fresh air to the combustion chamber via an intake tract;
- compressing the fresh air by means of a compressor of a turbocharger in the intake tract;
- producing hydrogen and oxygen gas for the internal combustion engine by means of an electrolysis device;
- and
- supplying alcohols from an alcohol tank to the internal combustion engine, wherein the alcohols and water are supplied from a water tank on a pressure side of the compressor;
- and
- wherein the hydrogen and oxygen gas of the electrolysis device are supplied on the pressure side of the compressor.
