It is worth mentioning that the "two aircraft (aero-engine and gas turbine) special" have also been discussed and passed by senior officials, are being prepared for implementation and some work has started. In addition, the state is preparing to launch a special project for the development of low-speed diesel engines, which is currently under discussion. The building of "China's heart" is still "on the road." China's first self-developed new low-speed small-bore marine diesel engine 6EX340EF and a 10000kW high-power medium-speed diesel engine 12MV390 at the 18th China International Maritime Convention officially released. Wu Qiang, general manager of China Shipbuilding Industry Corporation, the developer of both products, told China Industry Daily that the successful development of 6EX340EF and 12MV390 "twin computers" has filled the gaps in China and laid the foundations for the implementation of the innovation project of marine power autonomy during the "13th Five-Year Plan" A solid technical foundation. Foreign brands come out on top Marine engines include steam engines, steam turbines, diesel engines, gas turbines and nuclear power plants. Diesel engines are the mainstay. At present, diesel-powered ships account for over 95% of the world's merchant fleets. In recent years, dual-fuel engines based on liquefied natural gas (LNG) have also been applied on some types of ships and, by virtue of their excellent green performance, the industry has seen the trend of future ship power. Overall, marine power technology comes mainly from MAN, Wärtsilä, the traditional shipbuilding manufacturer. The global marine diesel engine manufacturers mainly use technology license to produce and sell. Among them, the old European diesel engine manufacturers represented by MAN and Wärtsilä occupy the majority of market share. In 2014, the two companies engaged in global low-speed marine diesel engines and Marine medium-speed diesel engine market share of 99% and 77%. Data shows that at present, South Korea, Japan and China have about 80% of the world's marine diesel engine market. Fierce competition among mainframe manufacturers also has a direct impact on the shipping industry's competition in the countries in which the vendors are located. Taking LNG carriers as an example, this high-end ship, a luxury jewel known as the "Pearl of the Crown", is the first ship to break the foreign monopoly in 2008 and become an international LNG carrier The leader in construction. However, our country is still at a disadvantage in the competition of LNG carrier engines. It is understood that nearly 70% of the world's LNG carriers use Wärtsilä dual-fuel engines. Hyundai Heavy Industries in order to seize the market opportunities, with the Wärtsilä Group established a joint venture Wärtsilä - Hyundai Motor Company, specializing in the production of 50DF-type dual-fuel engine. "In general, an LNG carrier needs four dual-fuel engines. If Chinese shipping companies can only use imported products while Korean shipping companies can produce for themselves, the two sides obviously will not compete on the same starting line." About the Experts . In fact, China's shipbuilding business did not give up the quest in the field of shipbuilding. Hudong Heavy Machinery, Dalian Marine Diesel Engine Company and other enterprises have entered the ranks of the world's top ten machine builder. However, it can not be avoided that there are still many shortcomings in the production of patents in our country. China started late in the field of marine engines, with a weak foundation and lack of advanced theoretical basis and accumulation of actual data, but also in the manufacturing process is subject to a variety of factors such as technology, materials and other constraints, so there are deficiencies in research and development, the key zero The performance of the components there is a big gap. Local motivation to catch up As a research and development platform for the power sector of China State Shipbuilding Corporation ("CSSC"), CSRI presented two marine diesel engines with its own brands to the 18th China International Maritime Conference and Exhibition. One of the most concerned about is that under the leadership and support of the Ministry of Industry and Information Technology, the 3-year-long generation of China's new generation of small-capacity low-speed marine diesel engine with a new generation catch up with the world's latest low-speed marine diesel engine, theEX340EF, is released for the first time in the global marine market. According to reports, 6EX340 series is a green, economical and low-speed diesel engine tailored by China Shipping Power Research Institute for China's Jianghai intermodal transport and offshore shipping. It adopts international advanced electronic control and fuel rail system and is equipped with high efficiency and high pressure ratio Turbocharger. At the same time, the two core indicators of high power output and low fuel consumption are fulfilled, meeting the International Maritime Organization (IMO) TierII emission standards. The key indicators are catching up with the international advanced technology of the same specifications of small bore and low speed diesel engines. In addition, the product manufacturability, manufacturing costs have a strong competitive advantage; also has high reliability, long overhaul, easy maintenance and other excellent quality. China Shipbuilding Institute of Power launched another type of independent brand 10000kW medium-speed machine 12MV390 10000kW, which lasted 5 years to build, is China's new generation to catch up with the world's latest level of its own brand of high-power medium-speed diesel engine, the aircraft also uses the most international Advanced electric control and fuel rail system, with a wide range of applications, high reliability, long overhaul and maintenance convenience and many other excellent features, the key indicators to catch up with the same range of medium-speed diesel engine of the international advanced technology level. His birth officially opened the road of independent development of China's high-power medium-speed machine.
