It is understood that the advent of the electronically controlled common rail marine main engine is a new revolution in the world diesel engine manufacturing industry. From the diesel engine orders of the world shipping industry in recent years, the electronically controlled common rail diesel engine is slowly replacing the traditional aircraft, in order to realize the ship. The engine is completely intelligent and paves the way. It is the perfect combination of modern advanced electronic technology, computer technology and traditional mechanical power technology, representing the development direction of contemporary marine mainframes and has broad market prospects.
This model uses the world's most advanced wecs9520 electronic control system to control fuel injection, exhaust valve closing, main engine start and reversing, replacing the traditional hydraulic and pneumatic control, making diesel combustion more complete. Thanks to the computer control, the camshaft system has been removed, the operation is simpler and more convenient, and the weight of the mainframe is effectively reduced, which is reliable, flexible and compatible. After being put into use, it will be effective in reducing fuel consumption, low noise, reducing exhaust emissions, extending overhaul period and "ultra-low speed" operation.
The successful development of the first 7RTflex58T-B electronically controlled common rail mainframe marks that the overall technical level, mainframe assembly and commissioning capability of CSIC Heavy Industry Group has reached world-class level, and at the same time, it has accumulated valuable for the future development of electronically controlled common rail series engines. experience of. At present, Dalian Shipai has become the largest enterprise in China for the handheld flex series electronically controlled common rail host.
