Recently，The All-China Federation of Trade Unions Holds the National May 1 Women's Award Recognition Conference in Beijing，Li Guohong, Chief Engineer of Heavy Locomotive Platform Technology of Yuchai Research and Development Institute, won the award“National May 1st Women's Pacesetter”Title。

He has worked for 17 years.，Li Guohong always sticks to the front line of internal combustion engine research and development.，Overall design of the whole machine、Key technological breakthroughs have been made in the design of key components.，To achieve self-reliance and self-improvement in science and technology for the country“The carbon reaches the peak、Carbon neutral”The strategic goal has contributed to women's strength.。She was awarded the May Day Labor Medal of Guangxi.、Honorary titles such as Excellent Communist Party Members of the Party Committee System of the SASAC of the Autonomous Region，Scientific research achievements won the second prize of Guangxi Science and Technology Award。

In order to grow quickly，Li Guohong has been rooted in the front line of R & D for decades.，Always be the last to leave the office，In addition to actively consulting senior experts on various issues,，It also makes full use of all available time to acquire professional knowledge.，Lay a solid foundation for R & D work。

2010，Li Guohong served as the new development of YuchaiSPlatform Product Manager，Shouldering to fill 3 in Guangxi～4LThe important task of blank displacement products。She knows，The product must be dynamic.、Economy、Sufficient competitive advantages in terms of reliability，Talent“Grab food from the tiger's mouth”，Break the monopoly of foreign brands，Occupy the high ground of the market。For this reason，Li Guohong led the R & D team to carry out low emissions day and night.、Research on low vibration noise and friction work reduction。

Six years to sharpen a sword，Out of the scabbard must be sharp。2016，Led by Li GuohongYC4SOnce the engine is launched，It is economical and fuel-efficient.、Stable and reliable、Strong adaptability and other advantages quickly become the new favorite of the market.，Breaking foreign brands at one stroke“It smells good”Law，It has promoted the progress of key automotive parts matching technology.，Widely recognized by domestic customers，And won the second prize of Guangxi Science and Technology Award.，It has made outstanding contributions to the high-quality development of China's automobile industry.。

The road to success cannot be smooth.，When Yuchai develops products that meet the requirements of the sixth stage of national emission regulations，It is also accompanied by hardships and challenges.。2016，Yuchai starts the research and development of six national products，Li Guohong was appointed at the critical moment.YCK13NSenior Project Manager of China VI Gas Engine。She withstood the pressure of the market.、Research and development time is pressing and many other difficulties，Successfully solved the long-standing problem.YCK13NA stubborn illness，Smooth realization of batch production，It has become one of the best-selling national six heavy-duty engines in the domestic market.。

Li Guohong takes practical actions to help the country win the battle of defending the blue sky，Cashed “Women hold up half the sky.，Female engineers can also develop competitive products.” A promise。

Carefully refine China“Core”

Li Guohong has an unyielding spirit and enthusiasm in her heart.，She will always“Develop the most competitive products for the company，Let the world admire the power of Made in China”As one's own belief in struggle。

  

In recent years，Affected by the epidemic at home and abroad、The international situation is changing、Foreign technology giant constraints and other influences，The shortage of chips has become the top problem in the automotive industry.，Some of the engines were even missing for a time.ECUStop production。

In order to break through foreign technology monopoly,， Work out “Stuck in the neck” Problem ，Achieve key core technology freedom，Yuchai decided to develop independently.ECUSystem。Therefore，Li Guohong led the team.，In development 15LFor gas engines，It took two years to conquer autonomy.ECUTechnical difficulties of the system at the application level，ECUThe control accuracy and performance have reached the same level as the mainstream products abroad.，The 100 km gas consumption of the whole vehicle is 4% lower than that of domestic and foreign competitors%。Heavy-duty gas engine independently developed by China，I can finally feel proud and elated.。

On the Beijing Olympic Winter Games.，Yuchai Autonomous Controller, the only mass-produced application in China, is applied to thousands of Guoliu gas buses.，Provide services for travelers，Successfully completed the commuting service guarantee task with outstanding performance and was highly recognized by the Olympic Organizing Committee.。

Move forward by green“Carbon”New Road

2020，Proposed to be achieved in the country“Double Carbon”Target time，The development of Yuchai's generation of engines that meet the Sixth National Emission Regulation is nearing the end.。Li Guohong, who has not had time to breathe.，It has also devoted itself to the development of the new generation of engines in the Sixth National Congress of the Communist Party of China.。

She shuttles through the test beds every day.，Coordinate resources of all parties to solve R & D problems。Li Guohong led her team to complete it in only 70 days.YCK15 Pioneering Work of New Generation Engine from Project Establishment to Prototype Ignition。YCK15 with ultra-high detonation pressure design、Advantage of 150,000km ultra-long oil change mileage，Let customers use more worry-free。More importantly,，YCKR & D of 15 engine，Means ultra-low specific fuel consumption 174g/（kWh）The engine came into being，2% lower than domestic and foreign competitors with 15 liters of displacementg/（kWh），It's helping to achieve“Double Carbon”Achieve the goal，Li Guohong and her team have taken another step forward.。

  

At the same time，Li Guohong knows very well to realize“Double Carbon”Aim，It is far from enough to exert force only on traditional power.，We must devote ourselves to the research and development of new energy power.。Only half a year in 2022，She was involved in the research and development.YCK16HSuccessful ignition of hydrogen-fueled engine。The engine has a displacement of 15.93 liters，Maximum horsepower up to 560 horsepower，It is the largest displacement in China at present.、The most powerful hydrogen engine。The engine platform can be adapted to grey hydrogen、Green hydrogen、Methanol online hydrogen production and other fuels，Freely combinable fuel supply，Be able to achieve low carbon、Zero carbon power provides higher adaptability、More flexible solution，It has broad prospects for development.。YCK16HThe ignition was successful，It marks that China has taken another solid step on the track of zero-carbon energy power system.。

Big country's heavy weapons need big country's craftsmen to create meticulously.，Craftsman quality can not be separated from the careful carving of the technical elite.。In the cause you love.，Li Guohong“Tingying”The posture，Seventeen years are like a day.，Fighting in the Front Line of Technological Innovation of Internal Combustion Engine，Continuously achieve self-improvement and transcendence，He has made extraordinary achievements in ordinary posts.，It has made due contributions to the strength of national industry.。
