Method for operating a supercharged diesel internal combustion engine for ship propulsion, and a diesel internal combustion engine for carrying out the method

摘要

The ship's propulsion system contains a supercharged diesel internal combustion engine (1), a waste heat boiler (7), a steam turbine (17) with an electric power generator (18) which is connected to the waste heat boiler (7), and an auxiliary fan (15) for the delivery of scavenging and charging air, which has an electric drive (16). A control device (40, 42, 33, 35, 36) is provided for switching on the auxiliary fan (15) when excess waste heat energy is present. By switching on the auxiliary fan (15), the waste heat energy available is used for additional cooling of the diesel internal combustion engine. IMAGE
