32, the power is surging!!!

“32”! Determined to become a powerful country, the driving force is surging!

——Sidelights of Department of Energy and Power Engineering, School of Machinery and Vehicles

"Zengquan, this is your undergraduate graduation design and drawings 39 years ago. I've always kept them for you! I finally returned to my alma mater and gave them to you! I hope you can firmly remember the spirit of '32'."

In May 2021, Wang Zengquan and several other alumni of the former 32781 class of the School of Machinery and Vehicles returned to BIT to specially visit professors Wu Dachang, Wang Changmin and Qin Youfang. Wang Changmin carefully packed his "gift" and gave it to Wang Zengquan, a former student and chief scientist of China Ordnance Group.

Gentlemen in their 80s and students over half a hundred years old, the faded finished papers and several yellow drawings are still so familiar with the teachings that touch people's hearts, although time has faded from youth. The strong flavor of "32" is an endless link in the hearts of generations.

In Beijing Institute of Technology, since the 1950s, the majors of colleges and departments have been numbered with numbers, of which the second major of the third mechanical department, referred to as 32 major, has been used until now. "32" is the most proud title for teachers and students of the Department of Energy and Power Engineering of the College of Machinery and Vehicles. The simple two numbers have deep connotation.

Generations of energy power people of Beijing Institute of Technology inherit the red gene, engrave the feelings of being determined to become a powerful country, the persistence of establishing morality and cultivating people, and the spirit of innovation, and create the character and temperament of "32" people shining with the spirit of Beijing Institute of Technology.


Determined to become a powerful country is a responsibility engraved in the bones.

In the clear sky, 70 salutes resounded through the sky, the bright five-star red flag rose slowly, the ten mile long street, rolling iron flow, and the majestic national prestige attracted the attention of the world.

On the morning of October 1, 2019, the celebration of the 70th anniversary of the National Day was grandly held in Tiananmen Square. In a ward 10 kilometers from the square, a pair of eyes stared at the picture on the TV screen and burst out the brilliance that had not been seen for a long time.

The owner of these eyes is Liu Fushui. He is a professor in the Department of Energy and Power Engineering of the School of Machinery and Vehicles and the chief designer of the power plant of a national special vehicle. At this time, Liu Fushui was suffering from cancer. He could only focus on the results of his efforts through TV in the ward and bloom in front of Tiananmen Square.

"Serving the motherland is my unswerving ambition!" In 2003, after three years of hard study in Germany, Dr. Liu Fushui, 40, graduated successfully. Facing the choice of whether to return home, Liu Fushui did not hesitate.

Liu Fushui, both undergraduate and master, majored in Internal Combustion Engine of Beijing Institute of Technology. As a standard "32" person, he stayed in school after his master's degree and devoted himself to his favorite vehicle power research. In 2000, Liu Fushui went to Germany to study for his doctorate and devoted himself to engine design theory. In a foreign country, "learning knowledge well and serving the motherland" has become the only belief in Liu Fushui's heart. After returning home, Liu Fushui couldn't wait to invest in the research projects urgently needed by the country. After 12 years of hard work, he finally developed a special vehicle engine representing the highest level in China.

"May China's energy and power disciplines become one of the most popular in the world as soon as possible! May the Chinese nation become a design and manufacturing power as soon as possible!" On September 11, 2020, 57 year old Liu Fushui left without time to check hundreds of unread teacher's Day blessings in his mobile phone. On his deathbed, what he left to his family, colleagues and students is still the deep patriotism and ambition to serve the country in the bones of the "32" people of BIT.

In 1956, teachers of Energy and Power System took a group photo (Cheng Changqi on the fourth left in the first row and Qin Youfang on the first right in the second row)

"In that year, Mr. Cheng Changqi independently designed the spring foundation and developed a universal single cylinder performance test machine with an old Toyota gasoline engine, a cooling system made of gasoline barrels and small water pumps, as well as test instruments made of portable mechanical tachometer, mechanical stopwatch and glass oil gauge."

Qin Youfang, a 90 year old former president of the College of Cehicle Engineering, recalled that Cheng Changqi, an old professor of 32 majors in the college, was still full of admiration.

In 1953, Cheng Changqi, 26, is a young teaching assistant majoring in 32 at Beijing Institute of Technology (the predecessor of Beijing Institute of Technology). It is his task to prepare for the establishment of BIT's power laboratory. Cheng Changqi has "nothing" except two temporary bungalows, but his sense of mission to cultivate urgently needed talents for the country makes Cheng Changqi "have everything" 。 Since then, in less than a year, Cheng Changqi led Liu Zongchang, Zhong Jingfang, Chen Ying, Guan Mingyue and other professors to check literature and design, built an experimental platform that can test engine crankshaft speed and fuel consumption, and successfully opened a teaching experiment of engine principle for 1950 students. At that time, there were only two such experimental platforms in the country. After 25 years, Cheng Changqi, who has become the leader of 32 disciplines, won the National Science Conference Award in 1978 for "Research on Omega Combustion Chamber of High-speed Diesel Engine".

"For the country, as long as you can't die, you'll die." The simple words, imbued with the commitment to becoming a powerful country, are deeply engraved in the bones of the "32" people. With the rotation of years and the flow of time, the red gene is still inherited from generation to generation, and the baton of a powerful country has been steadily handed over to the new generation of "32" people.

In 2021, Cui Tao, a 40 year old "32" teacher, tried to resist the high altitude reaction of splitting headache in the cold plateau area of minus 40 ℃, took off his gloves from time to time, and connected the test cable with his red hands. Looking at the distance, the white snow peak, set off by the five-star red flag, is particularly bright!


Establishing morality and cultivating people is the mission of continuous inheritance.

Yellow color, framed frame, this is 2 "drawing No. 0", 841mm × 1189 mm, the hand drawn lines are vertical and horizontal and straight, the tolerance fit is accurate and in place, and the clear structure of the starting motivation is outlined.

At the entrance of the East Building of the Engine Experimental Building of BIT, two engine drawings drawn by 32 professors and students in the 1950s and 1980s are hung. Every teacher and student passing by can't help glancing. The rigorous temperament contained in it deeply touches the heart.

"The university should give every student the most wonderful youth. As a teacher, it is a very beautiful thing to keep a memory of their growth." Wang Changmin, mentioned at the beginning of the article, retained these two drawings. For the sake of students and teaching students well, it has become the persistent pursuit of all teachers at the beginning of the establishment of 32 major.

In the 1980s, Wang Changmin was with the students.

After graduating from Shanghai Jiaotong University in 1956, Wang Changmin came to Beijing Institute of Technology to teach with the ambition of becoming an excellent university teacher of Internal Combustion Engine. At that time, domestic colleges and universities studied the Soviet model and paid special attention to practice in teaching. In order to enable students to carry out good practical learning,  Wang Changmin worked hard to establish a practical training system for 32 professional students from engine disassembly practice to curriculum design, production practice and graduation design, and often ran between schools and internship units to prepare students for internship. At that time, just after the Spring Festival, students were going to practice. In order to make a good front stop, I don't know how many Spring Festival, Wang Changmin spent alone in the practice unit.

"Treating students completely is like treating their own children. This is the mission of our '32' people." Zuo Zhengxing, Professor of the Department of Energy and Power Engineering and former Party Secretary of the College of Machinery and Vehicles, thinks so.

The vehicle diesel engine with the highest single point efficiency, the vehicle gasoline engine with the highest comprehensive efficiency, the special engine with the highest lifting power, the ship engine with the largest total power, and the UAV Engine with the largest specific power... The students keep studying and communicating around one engine, which are 32 professional responsible professors Zhang Weizheng, a famous profwssor in Beijing, is teaching the principles of internal combustion engine.

Zhang Weizheng is in class.

"Students learn theory and practice, and exercise their ability to solve practical problems in the process of consulting literature, formulating plans, analysis and discussion, calculation and research." In order to enable students to learn well and thoroughly, Zhang Weizheng actively promoted the research-based curriculum reform, added the "flipped classroom" link, guided students to have full discussion in the classroom, arranged the calculation research practice link, and organized students to study, calculate and design in groups.

"If students understand, use and give good feedback, my teaching will be successful." In the past 30 years of teaching, from teaching professional courses to organizing production practice and carrying out graduation practice, Zhang Weizheng, who was once a "32" student, took over the baton of predecessors to cultivate virtue and people, and worked hard in the teaching career.

"32 people from generation to generation carry forward the tradition of educating people, work steadily, inherit the spiritual tradition of the older generation, and cultivate a batch of outstanding talents worthy of important tasks for the Party and the country." Liao Ridong, Secretary of the general Party branch of the Department of Energy and Power Engineering, said. According to statistics, the chief designers of power systems of special vehicles independently developed by new China have all come from the 32 major of Beijing Institute of Technology.

The professors participated in the teaching method exchange activities of 32 teaching and research rooms.

"The teachers are very involved in the debate, and outsiders seem to think they are quarrelling! Science and engineering teachers are sometimes not good at sharing and expression, so the Department has strengthened communication through this form, which has also formed a good tradition." When it comes to the characteristic "32 Teaching and Research Department Teaching Method Exchange Activities", Liao Ridong said.

Since 2019, the Energy and Power Department has focused on the improvement of talent training quality and the training of young teachers, and created "32 Teaching and Research Room Teaching Method Exchange activities". Each activity is led by a teacher, from professional courses to basic courses, from undergraduate training to graduate guidance. The teaching method exchange is not limited to the theme, but clearly requires teachers as listeners to play the role of students, Comment and exchange with the speaker.

In the past three years, the teaching method exchange activities have been fully affirmed by the teachers, and have also become a stage for new teachers to collide with their thinking. The old professors have been newly inspired, and the new teachers have learned the "old methods". In the exchange and collision of ideas, the hearts of "32" people are closer and the hearts of teaching and educating people are more homogeneous. In recent years, teachers of the Department of Energy and Power Engineering have won the first prize in the Beijing basic teaching skills competition for three consecutive years.


Daring to be first is the pursuit of self-reliance and self-improvement

"This innovative direction has become one of the development directions of the industry in the next 15 years." Zuo Zhengxing evaluated the innovative research of modular intelligent power system.

Modular intelligent power system is a forward-looking and revolutionary innovative technology in the engine field. This technology changes the traditional way of transmitting energy with mechanical devices, directly converts heat energy into electric energy, and effectively reduces energy loss.

"To be the first is to be one step ahead of the national demand. One day, our industry needs to face higher challenges. Therefore, we need to look at the country and industry and layout in advance. This is the due intention of our innovation in Beigong." As the witness and witness of this innovative research, Zuo Zhengxing has a lot of feelings.

In 2003, the power system research team of the Department of Energy and Power Engineering where Zuo Zhengxing worked undertook full scientific research tasks and made continuous achievements. However, with the "32" people's thoughtful "vision" for the industry, the team teachers were not satisfied with the current situation, but boldly put forward the new research direction of modular intelligent dynamic power system and worked tirelessly for 20 years. In recent years, as a subversive development direction of new power technology, modular intelligent power system research has become a leader in the industry.

"We all think that to engage in power research is to 'play with fire'. In fact, some of us' play with water '. If we understand the matter of fluid, we can solve the problem of energy and power from another angle." Professor Wang Guoyu, director of the Institute of Fluid Mechanical Engineering, talked about his field with relish.

Wang Guoyu has worked deeply in the field of fluid mechanics for many years and led the team to stick to the research of cavitation flow. Cavitation refers to the phenomenon that the liquid on the surface of the shell of an object moving at high speed in water vaporizes due to high velocity. If the cavitation problem is not solved well, the high-speed movement of objects in water will lose control, and the consequences are very serious.

Professor Wang Guoyu is with his colleagues.

"Our innovation is to support and develop the computational methods and models of hydrodynamics through basic research, and then improve the level of solving engineering problems and serve the engineering needs of major national fields." Once, the speed of a special vehicle could not meet the standard in the process of wading. At the critical moment, Wang Guoyu was ordered to change the traditional method of increasing the thrust. Starting from the hydrodynamic characteristics of the vehicle, he successfully realized the original design goal and made outstanding contributions to the country by adding a simple hydrofoil to reduce the resistance.

"On the basis of basic research, innovation cannot be for innovation. Our university and department are engaged in applied technology, not subverting a theory in the fields of mathematics and physics. There is only one demand for innovation, that is, the needs of the country." For innovation, Wang Guoyu's views are full of "32" flavor.

Free piston engine, cavitation flow mechanism research, China's first hydrogen engine car, and the "Tissot" solar car that completed the world challenge... In the view of the "32" people, the first thing to dare to be a person is to aim at the forefront of world science and technology, strive to achieve high-level scientific and technological self-reliance and contribute to the construction of a scientific and technological power.

In the southeast corner of Zhongguancun campus of Beijing Institute of Technology, there are two simple small buildings, and the low floors are particularly low-key. With the passage of time and the changes of the times, the professors and students in and out of here have changed one stubble after another, and the green silk has become white hair.

Predecessors have developed and future generations have inherited. Behind the number of "32", generations of BIT workers who are determined to become a powerful country and dare to be the first have kept their spirit and aspirations unchanged.
