Description

technical field [0001] The invention relates to the technical field of marine diesel engines, in particular to a main propulsion control device for marine diesel engines. Background technique [0002] The marine diesel engine propulsion power module is mainly composed of single or multiple diesel engines, gearboxes, couplings, shaft motors and other equipment. Port operation tugboats driven by pure diesel engines have low thermal efficiency; based on the characteristics of port operation tugboat operations, the main engine is often in low-load conditions, and compared with the required power, fuel consumption and emissions are higher; oil energy costs are high, and emission pollution is large; it cannot meet Environmentally friendly development and air emission policy requirements, so hybrid power has become a new mainstream method. [0003] With the development and progress of society, higher technical requirements are put forward for the propulsion power module of marine ...

Problems solved by technology

Port operation tugboats driven by pure diesel engines have low thermal efficiency; based on the characteristics of port operation tugboat operations, the main engine is often in low-load conditions, and compared with the required power, fuel consumption and emissions are higher; oil energy costs are high, and emission pollution is large; it cannot meet Environmentally friendly development and air emission policy requirements, so hybrid power has become the new mainstream method

[0003] With the development and progress of society, higher technical requirements are put forward for the propulsion power module of marine diesel engines: it must not only meet the needs of propulsion power of ships, but also need to be matched with peripheral equipment such as paddles and shafts. There are few applications, and it is complicated and difficult to realize the translational movement of the hull by manually controlling multiple parameters of the propulsion device. Therefore, we propose a main propulsion control device for marine diesel engines to solve the above problems
