Abstract
The invention discloses an intermediate-speed high-power environment-friendly marine diesel engine. The intermediate-speed high-power environment-friendly marine diesel engine comprises a body which is formed by integrated casting, a dry type oil pan is arranged at the bottom of the body, a high-temperature cooling water pipeline, a crankshaft assembly, a cam shaft assembly and a damper assembly are internally arranged in the body, an electric protection system is arranged on the side face of a free end of the body, and an oil mist detector and an axle temperature alarm are arranged on the side face of an exhaust end of the body. An output end cover and a free end cover are externally hung on the body, and the free end cover is provided with a lubricating oil pump and a cooling water pump. The body at the output end of the diesel engine is provided with a turning mechanism, and a modular actuating unit capable of being lifted integrally is arranged on the body. According to the intermediate-speed high-power environment-friendly marine diesel engine, hot load bearing capacity of the diesel engine is improved; cheap heavy oil can be burned, and therefore fuel cost for operation of the diesel engine is reduced; emission of the intermediate-speed high-power environment-friendly marine diesel engine can meet the demand of IMOTier II; and lifting of the integrated actuating unit can be achieved, and whole maintenance performance can be improved.
Description
technical field [0001] The invention relates to a medium-speed and high-power environment-friendly marine diesel engine, which belongs to the technical field of diesel engines. Background technique [0002] Diesel engines have high thermal efficiency, good economy, easy starting, and great adaptability to various ships. They were soon used as propulsion and power generation power for ships after they came out. By the 1950s, diesel engines had almost completely replaced steam engines in newly built ships. At present, marine diesel engines are the main power for civilian ships, small and medium-sized ships and conventional submarines. Marine diesel engines can be divided into main engine and auxiliary engine according to their role in the ship. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive generators, air compressors or water pumps. [0003] Marine diesel engines are generally divided into high-speed, medium-speed and ...
