On September 5, 2022, YUCHAI held a high-quality development achievement exhibition of "Scientific and Technological Innovation and Quality Enterprise" in Yulin, showing the black technology that guarantees the quality and reliability of YUCHAI's products in all aspects, and decoding how YUCHAI creates a reliable ace power.

On the same day, Miao Qingwang, vice chairman of the autonomous region, Wu Jiashi, director of the market supervision bureau of the autonomous region, Bai Songtao, mayor of Yulin City, and leaders of municipal bureaus and outstanding enterprise representatives in the region visited the achievement exhibition, and Li Hanyang, chairman of YUCHAI, made an introduction.

YUCHAI's high-quality development results have received extensive attention from domestic mainstream media, including Xinhua News Agency, Science and Technology Daily, China Automobile News, China Communications News, China Consumer News, China Bus Information Network, Guangxi Daily, Guangxi TV, Truck E Family, Fangde Nearly 30 media, including the first commercial vehicle network, and Construction Machinery Weekly, came to visit and learn about YUCHAI's achievements in scientific and technological innovation, product reliability and technical highlights.

Technological innovation breaks through neck-stuck technology

This exhibition is divided into two parts: technical achievement exhibition and reliability achievement exhibition.

The technical achievement exhibition mainly displays hydrogen energy power innovation achievements such as hydrogen combustion engine and fuel cell, IE-power hybrid power, unmanned autonomous tractor, crawler tractor engine localization achievements and other agricultural machinery and construction machinery power innovation achievements, MTU real estate Chemical achievements, technological innovation achievements such as ECU chip products and UAV engines, and market supporting achievements such as fully supporting National VI and non-road National IV vehicle products.

Among them, the MTU real estate products are the outstanding achievements of the cooperation between YUCHAI and MTU Germany. The MTU real estate project has successfully developed real estate products that meet MTU technical standards 100% by fully benchmarking the international top manufacturing technology of MTU diesel engine parts, and has successfully entered the domestic space launch site, large data Centers, power plants, hospitals, airports, commercial buildings and public facilities, etc., have achieved German standards and created in China.

The drone equipped with the YUCHAI YCUAV56 engine has attracted everyone's attention. This engine is also the largest heavy oil or gasoline aviation piston engine with large-scale commercial mass production in China. In August, the first prototypes of two higher-horsepower aerodynamic engines were successfully ignited on YUCHAI's new bench. Since then, YUCHAI has added two new members to the product spectrum of aeroengine series, which also marks another solid step for YUCHAI in the field of aerodynamic engines.

Based on years of diesel engine technology precipitation, YUCHAI has made breakthroughs in key technologies such as heavy oil combustion anti-knock control, heavy oil reliability growth, and localization of YUCHAI's own ECU, and has carried out laboratory tests on this engine, tests under environmental simulation conditions and real environments. The on-board flight test and more than 2,000 hours of reliability testing ensure product reliability. The R&D process of this UAV engine product to the final product delivery, no matter from R&D, manufacturing process development, supplier development, factory testing, etc., the whole process is controlled according to the YUCHAI quality management system, combined with the special requirements of aviation power products. Adjust and adapt to fully meet the actual needs of customers.

The unmanned self-driving tractor exhibited at the scene adopts the YUCHAI agricultural machinery intelligent driving system, which can realize the intelligent control of the tractor's straight-line driving, automatic U-turn, and implement control. This means that in the near future, farmers and friends can also enjoy the convenience brought by driverless technology.

"Through the visit and the introduction of the lecturer, I can deeply feel YUCHAI's rigorous and high level of quality control. YUCHAI has a domestically leading National VI production line, which solves the problem of independent control ECU development, emission control technology, and hybrid powertrain technology. It is very good to introduce a series of 'neck neck' technology and launch a series of innovative products at the same time." said Liu Tao, general manager of the truck e family.

Carry out the whole process reliability assurance

The Reliability Achievement Exhibition focuses on displaying the whole process of power system R&D, manufacturing and service, reflecting YUCHAI's remarkable achievements in improving power system reliability.

In the field of research and development, YUCHAI has established several research laboratories and big data analysis rooms such as NVH test room, hydrogen engine test room, etc., based on customer needs, combined with YUCHAI's advantages in the powertrain field, and joint research and development with OEMs to fully carry out research and development. road test, crack the customer's actual product application pain points, and create products that are more in line with customer needs.

In the field of manufacturing, YUCHAI has national-level intelligent manufacturing demonstration projects, from the largest foundry center in Asia, to the machining and assembly workshop that has reached the German Industry 4.0 level, to the 11-year practice of lean manufacturing, YUCHAI "does both hard and soft", creating a leading industry manufacturing strength.

"I am deeply impressed by how YUCHAI is close to customers and serves customers. Especially in the workshop, I saw a master working for 1544 days without failure. He said, 'This engine I produced, treat it as I am using it for production. It.' Because the people who make the engine are doing it as if they are using this product, I think YUCHAI has so many supporting fields, which makes me feel that a hundred flowers are blooming, and in some fields it has become the king of flowers. " said Wang Shuhui of "Construction Machinery Weekly".

Service, as the strong "soft power" of YUCHAI, is also displayed in front of everyone. YUCHAI demonstrated the server-side big data and real-time status feedback system on the spot. This system allows us to quickly understand the service process and progress, further improve service efficiency, and allow customers to obtain all-round support.

In addition, YUCHAI also invited typical users of millions of kilometers without major repairs to share their car experience on the spot. The user said that the reason why his truck has achieved millions of kilometers without major repairs is inseparable from the support of the reliable YUCHAI ace power. "As long as it is properly maintained, millions of kilometers without major repairs are not a problem at all."

"YUCHAI's pursuit of product reliability and focus on user needs are beyond my expectations. For a manufacturing company, its core competitiveness in technology, manufacturing, and products determines whether it can survive the turbulent situation. The market occupies the commanding heights. During the whole visit, I found that YUCHAI’s perfect R&D, manufacturing, service integrated quality control model and strong technological innovation capabilities, as well as the pace of fuel saving and efficiency improvement, the first use of hydrogen energy, and the mass production of intelligent driving systems Fast, I am very shocked." Wu Bofeng of "China Consumer News" said.Editor/Ma Xue
