Weichai engine: reliable domestic
Weichai has been committed to doing the best engine, in the domestic leader, be unmatched in the international scope within the engine expert. Through the research and application of reliability in the technical aspects of the internal combustion engine in 2009, Weichai became the Key Laboratory of Shandong Province, the first batch of internal combustion engine reliability project construction. After that, a large number of studies have been carried out successively to take the lead in establishing the international technical innovation alliance for internal combustion engine reliability, and the reliability work group of the National Standardization Committee of internal combustion engines.
Weichai successfully declared national key laboratories, government support, effective integration of various resources, to carry out joint research of internal combustion engine reliability, sharing research results, can significantly enhance the level of China boost IC manufacturing, catch up with the world advanced level.
Weichai deep internal combustion engine industry for nearly 70 years, has a profound understanding of the reliability of internal combustion engine, for decades, Weichai always put product differentiation advantages in positioning reliability, and took 7 years to declare the State Key laboratory.
At present, China's entire manufacturing industry will exist or large or small reliability problems, that is, low quality. Low end and cheap haze have long influenced Chinese enterprises to enter the international high-end market. To achieve "quality power", the innovation is not necessarily novelty, and it is more urgent to carry out basic and comprehensive research. And reliability is the key to solve the problem of lock throat development in China's internal combustion engine.
The reliability research of internal combustion engine is not simply to extend the service life of the engine. Sometimes the customer's demand for internal combustion engines is not long life, but short life. A US customers find Weifang recently, want to do a batch of 250 hours of diesel engine assembly in fire truck. The use of fire engines is very low frequency, may not hit the fire for several years, the customer needs is in short life, to ensure that the engine can run at high quality at any time, and can withstand long-term idle.
At the same time, the upgrading of reliability is the basis and premise of energy saving, emission reduction and lightweight of internal combustion engine. The combustion level of internal combustion engine determines its energy consumption and emission level. In order to improve the combustion efficiency, the mechanical load and thermal load will increase accordingly, which requires the explosion pressure in the cylinder continue to expand. And the high burst pressure puts forward higher requirements for the reliability of internal combustion engine. Therefore, in order to apply energy-saving emission reduction technology to products, and to apply lightweight materials, the reliability must be guaranteed first.
This is also why the National Key Laboratory of internal combustion engine reliability is the main reason for the new scientific research of "new energy and low energy consumption vehicles". In other words, without the guarantee of reliability, the so-called new energy saving technologies and lightweight new materials are hard to come into play.
Performance of Weichai engine in reliability, this is called the industry first, after years of market baptism accumulation. In order to ensure the high reliability of products, in the development of links, a development process B701 Weichai industry's most stringent durability assessment index, far more than counterparts; in the manufacturing sectors, there are rigorous and sophisticated processing technology, strict quality control of the woven net, from the source to eliminate the fault; in the application of matching, Weifang also accumulated decades of experience have huge data resources, to ensure the perfect engine and vehicle matching.
