Build a platform to accelerate the development of the internal combustion engine industry

The improvement of reliability has become an industry consensus. After years of persistence and investment, high-quality reports and topics, and high-level guests, the annual International Symposium on Internal Combustion Engine Reliability has gradually become an industry event and a well-known international academic exchange platform in the industry. .

In this seminar, many academicians in the field of internal combustion engines and industry "big coffee" gathered together again, shining brilliantly. Tan Xuguang, director of the National Key Laboratory of Internal Combustion Engines and Power Systems, delivered a speech, Su Wanhua, academician of the Chinese Academy of Engineering, Liu Weimin, academician of the Chinese Academy of Sciences, Shu Gequn, Secretary of the Party Committee of the University of Science and Technology of China, Xu Changming, deputy director of the State Information Center, executive vice president and secretary of the China Internal Combustion Engine Industry Association More than 40 experts including Chang Xingmin focused on the internal combustion engine industry's requirements for the "double carbon" goal and the high-quality development of the equipment manufacturing industry, focusing on the reliability of the entire internal combustion engine, the reliability of key components of the internal combustion engine, and the reliability prediction and evaluation of internal combustion engines. The direction of academic exchanges and sharing.

The International Symposium on Internal Combustion Engine Reliability Technology has been successfully held for ten sessions so far, and its influence has been continuously improved, and it has become a well-known international academic exchange platform in the industry. With the help of this platform, more and more universities, scientific research institutions and enterprises have carried out cooperative research on key common technologies of internal combustion engine reliability, which has promoted the chain innovation of the internal combustion engine industry and played an important role in promoting the technological progress of internal combustion engine reliability in my country.

In the past, the research on the reliability of internal combustion engines is of great significance

The global economy is currently undergoing major changes unseen in a century. At this historical juncture where crises and opportunities coexist, it is quite urgent for the internal combustion engine industry to avoid risks scientifically and rationally and play its indispensable main role in order to bring a steady stream of surging momentum and reliable power to the transformation and upgrading of the manufacturing industry. and important.

The internal combustion engine is also the leading power for transportation, construction machinery, agricultural machinery, fishing vessels and national defense equipment, and is an important basic industry. Environmental protection requirements are a big challenge for internal combustion engines. With the full implementation of China VI and non-road four-stage emission standards, more complex post-processing also puts forward higher requirements for the reliability of internal combustion engines, especially in the "carbon peak" After the goal of "carbon neutrality" was put forward, improving thermal efficiency has become the best way to save energy and reduce emissions, but this will inevitably increase the working pressure of the engine and also have a certain impact on engine reliability.

The reliability of internal combustion engines directly affects the performance and service life of supporting equipment, and profoundly affects the sustainable development of my country's internal combustion engine industry and related industries. Improving the reliability of internal combustion engines is also one of the important ways for my country to achieve the goal of carbon peaking and carbon neutrality as soon as possible.

Up to now, the International Symposium on Reliability Technology of Internal Combustion Engines has been successfully held for ten sessions. It is said that if you don’t accumulate small steps, you can’t reach thousands of miles; With the continuous improvement of influence, the holding of the 11th International Symposium on Reliability Technology of Internal Combustion Engines is nothing less than the first to set off an ideological revolution and brainstorm in the world.

Leading by example, Weichai takes the lead in reliability research

Reliability is to internal combustion engines what water is to fish. Regarding reliability, Weichai has the most say. Weichai, which regards reliability as a differentiated strategy for corporate development, is not only a pioneer, a leader, but also a participant and witness.

In 2015, the only national key laboratory in my country's internal combustion engine industry, the State Key Laboratory of Internal Combustion Engine Reliability, settled in Weichai, which marks that China's internal combustion engine reliability technology research has moved to a higher level. Since its establishment, the laboratory has always taken it as its own responsibility to overcome the technical problems of internal combustion engine reliability, and has cooperated with many well-known universities and research institutes at home and abroad to vigorously carry out technical research to promote the innovation of internal combustion engine reliability technology. A total of 5 international standards, 20 national standards, 32 industry standards have been released, 676 patents have been authorized, including 330 invention patents, and 34 awards above the provincial and ministerial level have been awarded, including 1 first prize of the National Science and Technology Progress Award, and the National Technology Invention 1 second prize, 1 second prize of National Science and Technology Progress Award, and achieved fruitful results in key areas such as reliability basic theory research, reliability research of complete machines and key components, and reliability prediction and evaluation, especially reliability Increased from 1.2 million kilometers to 1.8 million kilometers. Since 2020, Weichai has successively released the world's first commercial diesel engines with body thermal efficiencies of 50.23%, 51.09%, and 52.28%, setting new benchmarks for the thermal efficiency of diesel engines in the world three times, leading my country's internal combustion engine industry to a world-class level.

As Tan Xuguang emphasized in his speech at the opening ceremony, high-power diesel engines will never disappear on the earth. Green and low-carbon development has become a global consensus. The internal combustion engine industry needs the leapfrog development of core technologies more than ever before. Subversive breakthroughs in cutting-edge technology are required, and integrated innovations from global peers are even more needed.

The world is gradually coming out of the haze of the epidemic, and the strong recovery of the Chinese economy is closely related to a strong and healthy manufacturing industry. And this is inseparable from the strong support of the internal combustion engine industry from beginning to end. The holding of the 11th International Symposium on Internal Combustion Engine Reliability Technology has allowed the world to see the passionate vitality and strong vitality of China's internal combustion engine industry, and witnessed that, like Weichai Power, it has become more courageous in the face of difficulties, striving to be the first and creating brilliance The leading enterprise of China has also output rich and colorful wisdom and abundant and reliable power for the strong rise of China's manufacturing industry and the orderly development of its peers, and firmly established a clear compass for the positive recovery of the global economy.
