Ship drive system and retrofitting method for a ship drive system

摘要

The invention relates to a ship drive system comprising at least one internal combustion engine (10a, 10b) with a combustion chamber (11a, 11b) for combusting a fuel and with a turbocharger (13a, 13b) comprising a compressor (14a, 14b) in an intake tract (12a, 12b) of the internal combustion engine (10a, 10b). The ship drive system additionally comprises an electrolysis device (20) which generates hydrogen and oxygen gas that are added to the pressure side of the compressor (14a, 14b) and conducted to the internal combustion engine (10a, 10b). Additionally, a water tank (31) and an alcohol tank (30) are connected to the pressure side of the compressor (14a, 14b) in order to add water and alcohol to the charge air.
