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 â€œinternal combustion engines. "Reliability International Technology Innovation Alliance", the Reliability Committee of the National Standardization Committee for Internal Combustion Engines, etc.

Weichai Engine

Recently, the Ministry of Science and Technology formally approved Weichaiâ€™s State Key Laboratory of Reliability of Internal Combustion Engines. Weichai has been cultivating the internal-combustion engine industry for nearly 70 years and has a deep understanding of the reliability of the internal combustion engine. For decades, Weichai has always positioned its differentiated advantages in terms of reliability, and spent 7 years reporting to the national key laboratory.

The low reliability is not only an example of the Chinese auto industry, but it is a common problem of the entire â€œMade in Chinaâ€. 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 â€œquality powerâ€, 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.

Research on the reliability of internal combustion engines 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.

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 â€œnew energy and low-energy vehiclesâ€ 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.

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.
