Recently，By the Central Committee of the Communist Youth League、Jointly issued by the Ministry of Human Resources and Social Security《Decision on Naming and Commending the 21st National Young Professionals》，Among，Xiao Gang, Chief Engineer of Yuchai Pioneer Diesel Engine Performance Development, won the award“National Young Professionals”Title。

“Actually, there is nothing‘Most’，Because there are many things that can give me a sense of achievement in Yuchai.，Uch as the ignition of a hydrogen-fueled engine、The thermal efficiency of the diesel engine is improved，Including revision of international standards、IPD（Integrated Product Development）Process development, etc；There's nothing to it.‘Proud’，Because I am soberly aware that this is actually an opportunity for enterprise platforms.，I didn't create it personally.。”When I was interviewed about what I was most proud of at work.，Xiao Gang made the above answer modestly.。

Whether as the chief engineer of Yuchai Pioneer Diesel Engine Performance Development，Or as a doctor?，Xiao Gang's reaction is a little flat.，But that's the secret of what he's achieved.：Always be curious，And dare to meet the challenge.。So，Let's follow Xiao Gang's past.，To realize his original intention and mission of sticking to the research and development of internal combustion engine。

Growth period：Affinity with internal combustion engine specialty and enterprise

After choosing the direction of internal combustion engine as the first choice of university，Xiao Gang began to make down-to-earth progress on this road.，As the leading enterprise in the domestic internal combustion engine industry, Yuchai，Nature also quietly entered his field of vision.。Studied in the State Key Laboratory of Combustion of Internal Combustion Engines of Tianjin University，Xiao Gang has participated in many Yuchai projects.，I also came into contact with many Yuchai people.。Yuchai people's pursuit of excellence in product technology，He was deeply impressed.，And has always inspired and urged him to be down-to-earth.、Seek truth from facts and carry out research work。The period of choosing a job，Xiao Gang only sent his resume to Yuchai.，Even though Guangxi is not his hometown.，Even far from his hometown.，But he firmly chose to join Yuchai.。Because Yuchai，It is the hot spot of innovation and research in his heart.，Is that he can show what he has learned.、A broad stage for talent。
Transition period：All experiences are preparation for the future.

After coming to Yuchai，The different working environments of institutions of higher learning and enterprises have brought some troubles to Xiao Gang.。Just started，Based on the company's strategic development needs，Xiao Gang was assigned to develop natural gas engines.，This is not an area of technology he is familiar with.；Catch，The period of intensive job rotation is coming.，CAESimulation、Component design、Diesel engine performance、Hydrogen engine development and so on.，Every job adjustment is a great challenge.，If you want to do well in every challenge,，It means the transformation and reconstruction of a large number of professional knowledge.、The change and improvement of professional ability is even the reset of research thinking.。Xiao Gang, who wants to do these research and development work well，At first, I often couldn't sleep because of stress.，But he gritted his teeth and persevered.，Make up for basic knowledge and cutting-edge technology research results by oneself，Broaden your horizons，Tirelessly absorb and digest the internal combustion engine technology accumulated and precipitated by Yuchai for more than 70 years.。In the meantime，Xiao Gang participated and finished it.“Sino-US Joint Research on Key Technologies for Improving Energy Efficiency of Medium-duty and Heavy-duty Truck”“High Cost Performance Commercial Vehicle Hybrid Power System Development and Vehicle Integration”Key R & D projects in other industries，His identity has also changed from engineer to chief engineer of diesel engine performance development.、Conversion of Director of Internal Combustion Engine Performance Development，At the same time, it assumes the dual responsibilities of technology and management.。

Maturity：Launching the ultimate challenge to hydrogen-fueled engines

Hydrogen-fueled engine is the implementation of China's internal combustion engine industry“Double Carbon”The important technical path of the target，It is also a hot technology research field in recent years.，Including internal combustion engine technology research institutes in Europe and the United States、Automobile enterprises have started the research and development of hydrogen-fueled engines.，However, there are still many technical problems to be overcome in the research and development of engine body and its production and manufacturing.。At this juncture，Xiao Gang took over the arduous task of hydrogen engine development.，He said：The development of hydrogen-fueled engines is a national strategic need.，It's also Yuchai“1235”Strategic needs，Yuchai is a leading enterprise in the internal combustion engine industry.，It has always taken the research and development of efficient environmental protection power as the core task of fulfilling social environmental protection responsibility.，Our Yuchai technical developers are even more duty-bound.“Double Carbon”Contribute your wisdom and strength to the achievement of your goals.。

YuchaiYCK05 Since the official establishment of the hydrogen engine project，There is no development experience for reference in the past.，Plus the scarcity of key components such as nozzles.、The theoretical research and practical application of hydrogen combustion mechanism have brought great difficulties to the development work.。In the beginning，Xiao Gang is perturbed.，The development of any new technology is always accompanied by difficulties and risks.，But on the other hand，As the project leader，He wants to build up confidence in the team that the mission will be achieved.，Make a good plan for the technical route and direction，Even the design of every experiment.。

Under such intense and unspeakable pressure.，Xiao Gang led the team to complete the task.，December 2021，YuchaiYCK05 successful ignition of hydrogen-fueled engine。High-pressure multi-point inlet injection technology is adopted in this model.、High efficiency and low inertia turbocharging technology、High efficiency lean combustion technology and many other advanced technologies，And that structure of the whole machine、Combustion and gas distribution subsystems have been comprehensively optimized and upgraded.，Overcome the problem of easy backfire of hydrogen engine、Easy to knock and other technical problems，Can be widely apply to public transport.、Municipal、Sanitation、Logistics distribution and other scenarios，It is the first commercial vehicle hydrogen engine in China.。The high evaluation and praise in the industry did not make Xiao Gang lose his original intention.，He said：“Our goal is not just to make a prototype.，It is to truly become an emerging force in the power industry.。”In that proces of converting the hydrogen engine development technology into a large-scale commercial technology,，There is still a lot of development.、Test、Process-based、Systematic work should be done.，There is a long way to go.。

Always be curious，And dare to meet the challenge.。As mentioned in Yuchai Struggle Culture“Have a sense of crisis，Set up the ambition of catching up and surpassing，Collect stones from other hills，Carry out the method of lean，Raise the wind of struggle，Be a goose of example”，On the way to the future，Xiao Gang will continue to stick to Yuchai，Continuous progress and challenge，Lead his team to innovate and create based on the post，Complete more advanced technology research and development of internal combustion engine，To introduce more efficient and energy-saving power products for customers。
