On April 13, the 8th International Symposium on Internal Combustion Engine Reliability Technology was held in Beijing. Huang Guoliang, Director of the Bureau of Quality Development of the State Administration of Market Supervision and Administration, said that in the future, no matter how new energy develops, internal combustion engines are indispensable for production and life. In the process of internal combustion engine reliability research, it is important to focus on both speed and passion, and safety and rationality.

 Currently, there are some views in the industry that new energy will replace traditional energy and that traditional energy may be withdrawn in the future. In response, Tan Xugang, director of the National Laboratory of Internal Combustion Engine Reliability, said that new energy sources will become an important part of the future energy mix worldwide. In the 30-50 years that can be expected, diesel engines are irreplaceable. A fairly long transition period for hybrids within cities is expected. It is also unlikely that heavy trucks will be replaced by new energy vehicles.

"The internal combustion engine is the core power source in industry and will continue to play an irreplaceable and important role for a longer period of time to come." Tan Xiguang stressed.

In the important process of transforming China's economy from high-rate growth to high-quality development and manufacturing, the reliability of internal combustion engines and the research and breakthrough of key common technologies are increasingly becoming the focus of industry attention. Reliability is one of the important indicators to measure the quality of internal combustion engines and determines product quality and core competitiveness.

However, Tan Xiguang admits that there is still a big gap between Chinese internal combustion engine enterprises and European and American countries, and domestic consumers' awareness of their rights is not strong. At present, the national six stage of the emission warranty period and effective life of higher requirements, and strengthen the OBD (on-board diagnostic system) regulation, high-speed logistics vehicles, trunk logistics vehicles have higher requirements, internal combustion engine reliability will usher in a qualitative leap.

It is understood that the National Laboratory of Internal Combustion Engine Reliability is an enterprise national laboratory in China's internal combustion engine industry, and since its establishment in 2015, it has invested a total of more than 10 million yuan fund to finance 40 open projects to support universities and research institutes to carry out research on the basic theory of internal combustion engine reliability and common technology research before competition, in the engine thermal fatigue technology, mechanical fatigue technology, friction and wear technology, sealing technology The National Laboratory of Internal Combustion Engine Reliability has achieved fruitful results in key common technologies involving internal combustion engine reliability such as thermal fatigue technology, mechanical fatigue technology, friction and wear technology, sealing technology, reliability prediction technology, fault online diagnosis technology, etc.

"The National Laboratory of Internal Combustion Engine Reliability has carried out fruitful work in external cooperation, and has carried out more than 40 open projects, and received more than 60 project applications from all over the world this year. At present, the open cooperation mechanism and technical exchange atmosphere of the National Laboratory have basically taken shape." Wen Xueyou, an academician of the Chinese Academy of Engineering, said.

Tan Xiguang said that there are still shortcomings in China's engines, especially high-speed engines. As the relying unit of the Internal Combustion Engine Reliability Laboratory, Weichai is actively promoting its products to the world, especially in terms of civil-military integration, and hopes to achieve a breakthrough within 3-5 years.

It is understood that in 2018, Weichai achieved sales revenue of 236 billion yuan, up 7% year-on-year; profit of 13.9 billion yuan, up 30%, with profit growth much higher than revenue growth, achieving high-quality development. Tan Xugang revealed that in the future, Weichai will continue to increase investment in research and development, focus closely on the core business of engines, base on global resources, and strengthen the main industry of equipment manufacturing without distractions.

The new Ginkob product is more adaptable than the retarder and will pay for itself much faster

Engine braking is increasingly recognised by drivers for its ability to significantly reduce wear and tear on the brakes and for its more reliable operation. The general principle of engine braking is to use the engine's compression stroke to generate compression resistance, internal friction and intake and exhaust resistance to form a braking effect on the drive wheels and thus slow down.

Warmly celebrate the company passed the TS16949 quality certification system Limited

Excellent quality and efficient management is our core competitiveness, expand market sales, and through the TS16949 quality system certification, the company is on stage before the recognition of the work, but also the future goals and encouragement. In the company's accurate cooperation and careful preparation, our company in September 2005 ushered in the AQA international certification company for our company to implement the TS16949 quality system audit. And in January 2006 passed the examination and got the certificate.
