The full report is as follows
July 5, just after 7 a.m.，Xu Yanni, dressed in overalls, appeared in Guangxi Yuchai Machinery Co., Ltd.（Hereinafter referred to as“Yuchai”）。From presiding over the workshop morning meeting to arranging production tasks，She is the head of the assembly line of the new product trial production workshop of Yuchai Manufacturing Division.，As soon as I arrived at the company, I was busy.。
30 years of hard work，Let Xu Yanni grow from an ordinary engine assembler to a super technician.。She can't remember how many machines she has assembled.，I can't remember how many engines I've done.“Physical examination”。The product that passed through her hands.，Everyone is very relieved.。Not long ago，Xu Yanni was named the National March 8th Red-Banner Pacesetter。
Since entering Yuchai in 1994,，Xu Yanni has been fighting in the production line.。With an unyielding spirit.，Xu Yanni is in the same batch of workers in the factory.，He was first promoted to senior technician.。
March 2018，Yuchai Starts to Meet the Sixth Phase of National Motor Vehicle Pollutant Emission Standards（Hereinafter referred to as“China VI”）Small batch production of engine。June of the same year，Xu Yanni was arranged to be responsible for the trial production and assembly of the new engine of the sixth national standard.。
“The trial production of new products is extraordinary.，Each round of assembly may face different difficulties.。”Xu Yanni said，She works with the team.，The quality and performance of the new engine meet the expected standards.，Lay a solid foundation for subsequent batch production。
Developed by YuchaiYCK05HHydrogen engine is the first commercial Vehicle hydrogen engine in China.，Complete ignition and stable operation in December 2021。Early 2022，Xu Yanni and the team took onYCK05HAssembly work on hydrogen-fueled engine。
“2020‘Double Carbon’After the goal is put forward，Scientific researchers in the automotive engine industry strive to make products、Equipment is developing in the direction of green and low carbon。After fully understanding the industry situation, the company's technical team，Decide on R & DYCK05HHydrogen engine，Help to achieve‘Double Carbon’Aim。The assembly of new engine is very important。”Xu Yanni said。
After that，Xu Yanni led the team members to conduct a comprehensive physical examination of the engine.，As small as flange face bolt，As large as a supercharger，She won't let go of every little part.。She also made a decision.“Day coordination”、“Weekly spot inspection”And other working mechanisms，Strive to advance the progress of work as soon as possible。
With the efforts of Xu Yanni and her team，YCK05HThe hydrogen-fueled engine has few problems in many rounds of trial production.，And successfully passed the feasibility verification.。
Under the management of Xu Yanni，The performance of Yuchai new product trial production workshop is fully up to the standard.，Engine batch pass rate increased to 92%，The probability of trial operation is up to 95.5%，Shorten the production cycle by more than half。With excellent product quality，Yuchai's new products have been recognized by many customers after listing.。
In addition to promoting the listing of new products，Xu Yanni also founded Yuchai Female Workers Innovation Studio and Xu Yanni Labor Model Innovation Studio.。She led the studio team members to tackle key technical problems.，Promote the innovation and development of enterprises。
“We not only optimize、Improve the production line，It also actively explores the application of new technologies.。”Xu Yanni said。In the studio，She led the team members to study and solve the problems encountered in the production process.。
Once ，Xu Yanni found employees installing hydraulic cylinder end caps at the production site.UType a seal ring，Pinch the seal ring by hand to deform it.，And then insert it into that hole of the end cap，Then use a screwdriver，To pry、Pick、Pressure and other ways，Press the sealing ring into the sealing groove little by little。
“Such a mode of operation，It is not only easy to damage the seal ring，It is also time-consuming and laborious。”Xu Yanni said，She and her colleagues analyzed it.，A seal ring mounting caliper has been designed。Use this caliper，Workers can complete the installation of sealing ring in less than 1 minute.。
July 2023，This caliper was unveiled at the 2nd Great Power Craftsman Innovation Exchange Conference and Great Power Craftsman Forum.，It has been concerned and recognized by many peers.。
In recent years，Xu Yanni's Labor Model Innovation Studio has overcome many technical problems.。Under her guidance.，The studio is finished“High strength and light weightVDevelopment of Aluminum Alloy Cylinder Head”And other 25 innovative projects，Five of these achievements have won national awards.。
“ These innovations show the strength of Xu Yanni and her team.，It has brought more than 10 million yuan of direct economic benefits to Yuchai. 。”Yuchai Technician Association、Kou Chuanfu, president of the Engineering Technology Association, said.。
“Maybe our position is very ordinary.，Every day is with a small part.‘Compete’，But the duty is not ordinary.。I hope to encourage more people to engage in technological innovation.，To contribute to the improvement of product quality。”Xu Yanni said。
