Marine QSK50 Diesel Engine

Author : Qijing Date : 2015-7-16 9:08:52
       Recently, cummins for the variable speed diesel electric propulsion (VSDE) market launch of the new optimized Marine QSK50 diesel engine.



Variable speed diesel electric generator is especially suitable for low load applications, such as ocean engineering ships, passenger ships, ferry, and fishing boats, and so on. And the traditional fixed speed diesel units are the same, variable speed diesel unit consists of a diesel engine, generator, control system and public base. But unlike traditional diesel, VSDE use of dc system, allows the engine to work under different rotational speed. System integrators previous report shows that it can significantly reduce fuel consumption, reduce carbon dioxide emissions, and the variable speed diesel system as a whole unit weight for constant speed applications. Also can reduce the user unit maintenance cost, and extend the service life of the engine.



Cummins engine power can also be used for existing VSDE, but new 2183 HP 1800 RPM QSK50 optimization designed for variable speed applications, in different working point are optimized for fuel economy. Power management system can achieve better effectiveness. VSDE optimization for cummins will continue to launch more power, all power products will meet ISO E2 E3 test cycle of IMO two-phase emission standards.
