From October 24 to November 23, 2015, Weichai has successively held seminars on technical upgrading of power equipment such as agricultural equipment, trucks , and passenger cars. Whether new products are released or technologies are upgraded, reliability has become the power of Weichai 2016. Product technology upgrade "the biggest ace." The support of Weichai's "reliability" advantage has become the "exclusive advantage" of internal combustion engine companies, and it represents the highest level of China's internal combustion engine manufacturing - the Weichai internal combustion engine reliability key laboratory that was successfully selected in the company's national key laboratory recently. On October 14, the Ministry of Science and Technology formally announced the list of the third batch of national key laboratories of enterprises. As a leader in the internal combustion engine industry, the Key Laboratory of Reliability of Internal Combustion Engines developed by Weichai passed approval. In order to further improve the layout of the State Key Laboratory, the construction of the third batch of State Key Laboratories started in 2014. According to the results of the expert review and comments, 75 laboratories, including the Weichai Engine Reliability Laboratory, passed the deliberation. The Weichai Engine Reliability Laboratory has a total investment of 550 million yuan, a building area of ​​11,200 square meters, and scientific research equipment of 260 million yuan. It can meet the research needs of the entire engine reliability, key component reliability, reliability prediction and evaluation, and so on. It has passed the national C-NAS accreditation and German TÃœV accreditation, and the equipment has reached the international advanced and domestic leading level. It is the most complete and most capable laboratory in the same industry in China. The supporting product trial center invested 250 million yuan and has 45 sets of high-precision equipment such as five-axis machining centers and quick-loading trolleys, which can fully meet the demand for test parts; it is equipped with an independent public system station house to ensure wind, electricity, and gas. Oil, cold, warm and other supplies. There are currently 138 laboratories in the laboratory, including 120 permanent personnel, including 4 national "Thousand Persons Projects", 8 "Taishan Scholars" of the People's Government of Shandong Province, and 50 senior professional titles. Research on reliability, reliability prediction and evaluation techniques are conducted in three directions. Since the “Twelfth Five-Year Planâ€, the laboratory has successively took on 8 national science and technology plan projects, participated in 6 national science and technology plan projects, led 93 scientific and technological planning projects in Shandong Province, and obtained 14 science and technology progress awards at the provincial and ministerial level. 675 patents were authorized and 47 papers were published, of which 3 papers were included in SCI and 11 papers were included in EI. The State Key Laboratory of Enterprises is an important part of the national technological innovation system. After deliberation, the Weichai IC Reliability Laboratory will focus on the needs of the society and the future development of the industry, carry out basic research and pre-competitive common technical research, study and formulate international standards, national and industry standards, and gather and train outstanding talents. And to promote industrial technological progress.

Air humidity and health
Effect of dry air on human body
People can easily distinguish the cold and heat of their environment, but the air humidity cannot be clearly perceived. We can't give immediate feedback on the water content of the air we breathe into our lungs or in contact with our skin and body.
However, air humidity will have a significant impact on us. If we are in extreme environment for a long time, it may cause damage.
Dry air draws water from any source it comes into contact with, including our bodies. Water can evaporate from our eyes, skin, hair, nails and any other body surface. This dehydration may initially cause discomfort, such as eye soreness or contact lens irritation, but it may also lead to more serious symptoms, such as dry skin, itching and dermatitis.
What's more, it affects our respiratory and immune systems. When the relative humidity of the air we breathe is less than 40%, the mucous membranes in the nose, throat and bronchus will become dry, and these elements play a vital role in our body's resistance to airborne pollutants (such as viruses and bacteria).
These moist mucous membranes trap airborne particles before they enter our lungs. Tiny hairs called cilia transport these contaminants to our throats, which are then coughed up or swallowed and destroyed. This process is called mucociliary clearance.
When our mucous membranes become dry, this natural defense mechanism will be inhibited, making us more vulnerable to airborne viruses and bacteria.
scientific basis
Over the years, a large number of studies and investigations have been carried out to demonstrate how humidity affects the human body. The following is a summary of these studies. These famous examples illustrate the benefits of maintaining an optimal humidity value for physical health and well-being
Selected as the largest ace of technology upgrade of Weichai 2016, a key national laboratory of selected companies.
