The turbocharged diesel engine has good adaptability, and the WD615C and WD618C series diesel engine flywheel, flywheel housing, diesel engine monitoring instrument, water jacket exhaust pipe, seawater pump and other components are universal. The installation dimensions, flywheel and flywheel housing dimensions of diesel engines are also the same, which facilitates matching and maintenance. The front pulley of the crankshaft is reserved with a pulley groove and a connecting flange for outdoor power output devices.

The accessories of the turbocharged diesel engine are fully installed, and the air cooler, fresh water heat exchanger, etc. are installed on the diesel engine to facilitate the layout of the engine compartment. The diesel engine cooling system adopts an internal and external dual circulation water cooling method. The internal circulation uses fresh water to cool the diesel engine, while the external circulation uses seawater to cool the fresh water through a sea fresh water heat exchanger, improving the service life of the diesel engine.
