Marine hosts most of the time the price of marine engines working under full load conditions, and sometimes operate at varying load conditions. Ships sailing often bumpy, so marine diesel engine should be able to trim under 15 ° ~ 25 ° and heeling 15 ° ~ 35 ° of reliable operation. Most of the ship using turbocharged diesel engine (see supercharged internal combustion engine), low power non-turbocharged diesel engine on the boat only. Most of the low-speed diesel engines for marine two-stroke engine manufacturers, the majority of medium-speed diesel four-stroke machines, and high-speed diesel engine is both. Scavenging two-stroke marine diesel engine in the form of a reflux scavenging, gas inlet - DC scavenging valve and the counter-piston scavenging air intake. High-power, and low-speed diesel engines widely used in heavy oil as fuel for marine engines, high speed diesel engines are still many with light diesel oil. Marine diesel engines to develop relations of major national political and economic security strategy, since 2003, the central leaders attach great importance to and fully affirmed the positive role of the shipbuilding industry in national economic development, especially in 2004 under the background of macro-control ship Industrial faster and greater development ardent expectations. In this context marine engine vendors, we believe that our marine diesel engine industry already has a foundation and favorable conditions by leaps and bounds in the next fifteen years, marine diesel engine manufacturing, China will most likely ranks first in the world. Perhaps due to the continued prosperity of the world shipbuilding industry, China's shipbuilding industry dominated the world may not need that long.
