Weichai Construction State Key Laboratory of Internal Combustion Engines Aimed at the Gap of Domestic Internal-Com

Weichai has made many efforts and contributions to the research and application of reliability technology of internal combustion engines. Since it became the first key laboratory for reliability testing of internal combustion engines established in Shandong Province in 2009, many researches have been carried out successively and lead the establishment of “internal combustion engines. "Reliability International Technology Innovation Alliance", the Reliability Committee of the National Standardization Committee for Internal Combustion Engines, etc.

A few days ago, the good news retransmitted, Weichai was approved to build the State Key Laboratory of Reliability of Internal Combustion Engines . To this end, the reporter conducted an exclusive interview with Wei Dehui, Vice President of Weichai Power, and asked him to talk about the establishment of the laboratory and what it means for Weichai and even the industry.

Weichai approved the State Key Laboratory of Reliability of Internal Combustion Engines

Solve common problems in manufacturing in China

For the State Key Laboratory of Weichi Diesel's Construction of Internal Combustion Engine Reliability officially approved by the Ministry of Science and Technology on October 14 this year, Yu Dehui believes that Weichai has been deeply cultivating the internal combustion engine industry for nearly 70 years and has a deep understanding of the reliability of the internal combustion engine. Weichai has always put products in place for decades. The differentiated advantages were positioned in terms of reliability, and it took seven years to apply for national key laboratories.

In the reporting process, experts in the industry also suggested that: What is the reliability of advanced technology? It is better to declare new energy-saving technologies, materials, and the like. However, Weichai still insists on reliability, because when it comes to benchmarking with the international industry, companies have discovered that the reliability of internal combustion engines is the biggest gap between China and the world's advanced level. Taking the B10 life of a vehicle diesel engine as an example, the US diesel engine is basically 1.5 million kilometers, the European diesel engine is 1.2 million kilometers, and China's diesel engine averages only 800,000 kilometers.

The low reliability is not only an example of the Chinese auto industry, but it is a common problem of the entire “Made in China”. China can create manned rockets, but went crazy to grab the Japanese toilet seat; China's wholesale market is filled with numerous small commodities, but no Swiss brand like the Saber. A knife, how many advanced technologies can be? The key is quality, which is reliability.

The low-cost, low-cost haze has long influenced Chinese companies to enter the international high-end market. To achieve a “quality power”, it is by no means an intriguing innovation. It is even more urgent to carry out basic and comprehensive research in a down-to-earth manner. Reliability is the key to resolving the pain of lock-throat development in China's internal combustion engines.

Weichai has successfully applied for the National Key Laboratory. With the support of the government, it collaborates with all parties' superior resources to jointly carry out research on the reliability of internal combustion engines and share the results of scientific research. It will certainly boost the level of China's internal combustion engine manufacturing, and catch up with the world's advanced level.

Focus on improving service life

Yu Dehui told reporters that reliability research is not simply to extend the life of the engine. Sometimes the customer's demand for internal combustion engines is not long life but short life. Recently, a U.S. customer tried to find a diesel engine and wanted to make a 250-hour diesel engine and install it on a fire engine. Fire trucks have a low frequency of use and may not be in contact with fire for several years. Customers need to ensure that the engine can operate with high quality at all times and in a short period of time, and can stand idle for a long time.

Therefore, in the future, Weichai will not only have a durable "marathon runner" but also have a powerful "sprinter". Weichai’s reliability study is based on the basic premise of satisfying the individual needs of customers and improving attendance quality and reducing failures in the custom-made lifespan.

Of course, in view of the current status of the Chinese auto industry, especially commercial vehicles, durability is still the most extensive demand of customers. Weichai's reliability research will focus on the service life of internal combustion engines.

At the same time, the improvement of reliability is still the basis and premise of the energy-saving, emission-reducing and light-duty combustion engine. The combustion level of the internal combustion engine determines its energy consumption and emission level. To increase the combustion efficiency, the mechanical load and the heat load must increase. This requires the explosion pressure in the cylinder to expand. The high burst pressure imposes higher requirements on the reliability of the internal combustion engine. Therefore, to apply energy-saving and emission-reduction technologies to products and to apply lightweight materials, reliability must be ensured first.

This is why the State Key Laboratory of Reliability of Internal Combustion Engines is the main reason for being anchored in the “new energy and low-energy vehicles” major research category. In other words, there is no guarantee of reliability. The so-called new energy-saving technologies and lightweight new materials are difficult to use.

Yan Dehui also talked about the significance of laboratory establishment and future planning of Weichai: The construction of the State Key Laboratory of Reliability of Internal Combustion Engines can not only promote the overall technological progress of China's internal combustion engines and related supporting industries, but also for Weichai. With this resource platform, corporate reliability studies can be more standardized and deeper, and there are more opportunities to participate in national and even international projects.

Integrate with international strength

For example, the recent visit of General Secretary Xi Jinping to the United States has formed a series of scientific research cooperation projects, one of which is the “low-energy car research”. Because of the platform of the State Key Laboratory of Internal Combustion Engine Reliability, the Ministry of Science and Technology invited Weichai to participate. Weichai can have close contact with the world's most cutting-edge technologies, which is very helpful for the improvement of the company's own level.

The laboratory is affiliated with Weichai, and Weichai coordinates the resources of the entire society for research. The sharing of scientific research results is a process of mutual benefit. In the future, Weichai will honor its commitment to invest 400 million yuan to complete related facilities within two years; open 20 research projects, fund at least 10 scientific research teams; host more than 2 international conferences; apply for more than 5 national and industry standards, More than 50 patents...

From here, we can also see that building a national key laboratory not only requires Weichai to have a considerable industry status and product reputation, but also needs a strong R&D capability and huge resource support. It is very difficult for an average company to assume such a heavy responsibility.

Weichai improves the reliability of the engine is not a day, but a complex system engineering, involving the entire engine and parts design, processing and assembly, and even closely related to the vehicle's calibration level.

Weichai's performance in reliability is the first in the industry, which is accumulated after years of baptism in the market. In order to ensure the high reliability of products, in the development process, Weichai has the industry's most rigorous R&D process, B701. The durability assessment index far exceeds that of peers. In the manufacturing process, there are also rigorous and mature processing technologies, weaving the strictest quality control. Network, from the source to eliminate the failure; in the application of matching, Weichai has accumulated decades of experience, has a huge data resources, to ensure the perfect match of the engine and the vehicle.

Some companies are keen to "innovation," preferring to use so-called "new technology" as a gimmick to win customers' attention. Weichai pays more attention to basic R&D, concentrates its resources on breakthroughs in key technologies, and steps up one step at a time to upgrade itself and even the industry. This is where Weichai is the social responsibility of the leading companies, and it is also the "establishment way" for Weichai to establish itself in the industry.
