When Yu Hang set foot on the land of Hushan, he suddenly felt steady, and in just 3 days, he quickly completed the resignation procedures and came to Hushan County, a poor rural area, from the metropolis of Hujiang. Pen, fun, and www.biquge.info

Faced with the unsupport of his family and the incomprehension of his colleagues, Yu Hang responded lightly.

"My hometown needs me, let time tell!"

Born before liberation and growing up under the red flag, Yu Hang has a high ideological consciousness, and he will not hesitate to do things that are beneficial to the country.

As the deputy chief engineer of the happy factory, how can he not know the disadvantages of the enterprise, and now the whole factory is proud of the joint venture, and only says nothing about independent innovation. Han Hao said that he failed to develop an engine that belonged to the Chinese themselves, nor could he build a motorcycle that belonged to the Chinese themselves, which deeply hurt the nerves of an old man with national self-esteem.

People live a lifetime, and they always have to leave something in history, even if it is a very small thing. Yu Hang decided to follow Han Hao to do a big job, even if he failed, he would have no regrets in his life.

When Yu Hang followed Han Hao to the gate of Han Yao's factory, all the R&D teams and workers spontaneously came to the door to line up to welcome him.

Hujiang City is the center of the Yangtze River Delta, but also the metropolis in everyone's minds, now a willing to give up the leisurely life of the big city, choose to come to Han Yao factory to work hard, how can not get everyone's welcome and respect!

"Bang Bang-"

As soon as he got out of the car, Yu Hang received warm applause, making him feel as if he had returned to the scene when he first set foot on African soil and was greeted with great enthusiasm.

"Presumably, even if this is the skilled craftsman of our team, I have already learned your excellent craftsmanship. ”

Without Han Hao's introduction, Yu Hang took the initiative to hold Miao Zhenhua's hand, because he saw a familiar temperament from the other party.

"I've won the prize, so please give me a lot of advice in the future. ”

Miao Zhenhua also shook hands and responded enthusiastically.

If the original team overcame 99% of the difficulties, then the remaining 1% of the hard bones had to be experts like Yu Hang.

After a brief lunch, Yu Hang officially led the entire team as the R&D commander and began to analyze and test the failure of the No. 0 machine.

In the evening, Hao Yishan also came to Han Yaochang, and when he learned that the elegant person in front of him was the famous Yu Hang, he was so surprised that his jaw almost fell to the ground.

"Mr. Yu, I just read your engine paper back then and embarked on the road of research and development, but I didn't expect to meet a real person today!"

Unlike Yu Hang, who dealt with various train and motorcycle engines after graduating, Hao Yishan was a halfway monk, and he was inspired by Yu Hang to turn to engine research.

Unexpectedly, Han Hao had such great ability, and invited the great expert Yu Hang to the factory. As soon as he returned home, Hao Yishan immediately wrote a resignation report and planned to join Han Hao's R&D team. These days, he feels more happiness in Hanyao Factory, and compared with the corpse vegetarian meal in Qianjiang Factory, he can realize his life ideals more here. Especially now that Yu Hang is here, solving the engine problem is just around the corner, and what he is looking forward to is working with his idol Yu Hang, which is Hao Yishan's biggest source of confidence.

Hao Yishan originally just wanted to leave alone, but he didn't expect that the subordinates of the Qianjiang factory heard that he was going outside to study a new engine, and four people were willing to leave and go with him.

Although the five people, including Hao Yishan, were a little worse in terms of creativity, they had a solid foundation in kung fu, and their arrival was definitely a big surprise for Han Hao.

Yu Hang is also very happy that the team brought by Hao Yishan can share a lot of his work, after all, compared with Niu Dawei, who is a secondary school graduate, they have more experience in system theory and practical operation.

As soon as the connoisseur makes a move, he will know if there is one.

Soon, Yu Hang locked the root cause of the fault between the box, the piston and the piston ring. After many tests, it was found that the die-casting process on the box was not up to standard, and there were pores inside the seemingly smooth surface detected by X-ray; the casting material of the piston was problematic and could not withstand high temperature work; the piston ring parts purchased from the same factory were not up to standard and were defective.

At the beginning, Han Hao found a small die-casting factory to cooperate, they did not have strict technical parameters, but relied on the reference literature that they got out of nowhere for die-casting, and the result was to create unqualified samples. Under the guidance of Yu Hang's team, the technical difficulties were finally overcome for three consecutive days, the machine pressure and cooling time were adjusted, and qualified box samples were produced.

In terms of pistons, the proportion of metal materials is not right, and the quenching steps in the process are not correct, resulting in the piston being unable to withstand high temperatures and easy to deform as soon as it works. After Yu Hang gave the correct formula and steps, the piston reached the normal standard.

As for the piston ring, when it was purchased, it was urgent, and the factory salesman sold it with defective products, which was a small trap. Generally speaking, defective products can also top the genuine products for most of the time, but I didn't expect that there were many problems with Han Yao's samples, and the small problems of the piston ring were magnified, so that the stuffing was exposed. When Han Hao sent someone to the door, the factory was very cheerful to reissue the piston rings that had been strictly inspected.

All the big problems are small problems that accumulate little by little, thus creating an unmanageable situation. Han Hao also learned from it that production is to pay attention to details, operate in strict accordance with the regulations, and not be sloppy.

Time flies, since Yu Hang came to the Hanyao factory has been 20 days, under his auspices, the R&D team has worked hard one by one, finally solved all the problems, and once again prepared for the official test run.

Eating and living in a simple dormitory in Han Yaochang, Yu Hang and his team worked day and night. Quenched with sweat, cast with wisdom, and polished with will, they finally created a new sample in the time of burning passion - No. 1 machine.

Niu Dawei still assembled the engine and connected the testing machine, and the exciting moment was coming.

"Suddenly-suddenly-"

The No. 1 engine quickly emitted a pleasant starting sound, which was quieter than the original engine and ran more smoothly.

Han Hao stood in the crowd, his hands clenched into fists, he had already experienced too many failures like everyone else, and he was desperate to usher in the clarion call for success.

As the minutes ticked by, the data displayed on the newly purchased test instrument was normal.

5 minutes - 10 minutes - 30 minutes - 45 minutes......

Everyone held their breath motionless, as if they were looking at a newborn baby, and watched the No. 1 machine run non-stop, and the roar was as loud as a baby's cry, tickling everyone's heart.

"Well, the initial test can be said to be basically successful. ”

Looking at the time, Yu Hang announced the test results in accordance with industry practice.

"Yay—it worked!"

Everyone present was excited, jumping and laughing happily, and finally reaped the joy of success after more than 3 months of hard work.

"It worked, I really made it......"

Han Hao couldn't believe all this, and after a series of unbearable failures, his team finally succeeded in copying the 70CC engine derived from Honda's technology.

Hard work pays off!

In order to study the engine, Han Hao gambled everything on his own, up to more than one million R&D funds, and as heavy mental pressure as a mountain, which made him breathless at all times.

Now that he has finally succeeded, he can go to his father's hospital bed to report the good news to his parents, he can go to a place where no one is there to cry and laugh, and he can go to all the people who did not think of him in the first place, smash the engine in their faces, and then shout to the world - I have finally succeeded!

Two lines of hot tears rolled down from Han Hao's eyes, the man didn't flick his tears, he waited too hard and too long for this day.

"Thank you...... Thank you all for your hard work and dedication......"

Everyone invited Han Hao to the front, and he wiped away his tears as he spoke.

Not only Han Hao at the scene, but almost all the people who participated in the research and development all the way couldn't help but cry with joy, even Yu Hang and Miao Zhenhua, who have rich life experience, wiped away the tears from the corners of their eyes with their hands.

"Tears are contagious, I don't know who got it to me!"

"Haha-"

Han Hao's words made everyone cry and laugh.

"Knowledge is productivity and wealth, so I announced that when our engines are industrialized, the factory will give a big reward to all those who contribute to the research and development work. ”

"Wow-"

Hearing such good news, everyone opened their mouths wide and then applauded together.

"The engine is the heart of the machine, and when the heart beats, our Hanyao factory will have unlimited development world. The No. 1 machine is just our starting point, and in the future, we will enter the fields of 90CC, 100CC, and 125CC, which are completely monopolized by foreign technology, and develop the No. 2 and No. 3 machines...... Until they break their technical blockade on us, create an engine with full intellectual property rights for our Chinese, and create our own motorcycle Chinese

Han Hao's words once again made everyone applaud. Everyone came to Hanyao Factory just to make a career. Now the leader Han Hao is not complacent, and said the direction of future development, so that everyone can see the direction of progress.

"Finally, I announce that I will hold a celebration banquet at Tengyun Pavilion, the best restaurant in town, to make up for everyone!"

That night, many people, including Niu Dawei, were drunk, and even Yu Hang and Miao Zhenhua, two old-timers, were poured a stomach full of wine.

But Han Hao is not drunk, he must keep a clear head and do a good job as a logistics housekeeper.

People can't get too carried away when they are proud, Han Hao has already suffered such a loss at the beginning. So even though he was supposed to be the happiest and most celebrating person at the scene, he suppressed the idea of celebrating and kept himself awake.

Arrange for sober people to send drunk people home or in the dormitory, and Han Hao didn't go home until he had dealt with all the trivial things.

The No. 1 machine was successfully tested at first, but it still needs to be tested on the road and passed the technical acceptance organized by the province and the state before it can be officially and legally put into market production.

For the next week, Sample 1 of Unit 1 ran non-stop on the test machine for 161 hours before lying on its stomach and was tested to be in normal condition. Samples 2 and 3 also work normally on the motorcycle, with plenty of power, exactly the same as the original 70CC.

Yu Hang led the team to make improvements to some small details, and then officially launched the mass production plan, and at the same time reported to the province for technical acceptance.

"What, you guys actually got a motorcycle engine?"

When they went to the county to report, the officials concerned looked incredulous, how could such a high-tech thing succeed in a small research institute in a township or township.

With suspicion, the county officials came to the Hanyao factory and saw the various finished products of the No. 1 machine, especially after Yu Hang's explanation, they really believed that someone in Hushan County had really made a 70cc motorcycle engine.

The county went to the city, and the city went to the province, and it was reported all the way as a major research achievement, and soon the province sent an expert group to Hanyao Factory to verify and organize acceptance.

The expert group is composed of 5 experts, including Han Hao's old acquaintance - Jiang Zhaoping, director of the Department of Mechanical Engineering of Zhejiang Institute of Technology.

As soon as they saw Yu Hang at the scene, the experts knew that the matter was inseparable. After all, the academic circle is not big, Yu Hang, as a well-known engine expert in China, saw the name in the application materials before and thought it was the same name and surname, and when he came to the scene to see the real person, he knew that it was the deity, and everyone knew his identity and status.

There were no surprises, and the No. 1 machine passed the acceptance of the expert group without any problems, after all, it comes from Honda's mature technology, a single-cylinder 4-stroke. There is basically no big action on the structure, but there are some small improvements, and the Jialing 70CC acceleration loves to shake the small problem of solving.

Although Yu Hang and Jiang Zhaoping talked on the phone from time to time, they met a year ago, and after the business was done, the two old classmates chatted privately.

"Lao Yu, how is my student? ”

"People are small and big, and there are talented people in the country!"

In front of his old classmates, Yu Hang couldn't help but sigh. Unexpectedly, when I came to Han Yao Factory, I seemed to have a second spring, and creativity was endless. He used the entire R&D team very easily, and Han Hao was also responsible for solving all problems outside of scientific research and making the whole team run smoothly.

Pulling Jiang Zhaoping to the side of the R&D room, Yu Hang lifted a red cloth, and the prototype, known internally as No. 2, was standing quietly in front of him.

Honda's technology is extensible, that is, there is a certain technological correlation between 70CC and 90CC, so Yu Hang soon changed the 90CC engine sample.

"Shhhh

Jiang Zhaoping took a deep breath, this time they just came to accept the 70CC machine, and they didn't expect that the 90CC machine Han Yao Factory was about to succeed in research.

"Awesome, really awesome! Okay, Lao Yu, you can't be famous now!"

Jiang Zhaoping was instructed to keep it secret, after all, 90CC is still under development, although success is just around the corner.

Han Hao also thanked his mentor Jiang Zhaoping for his help along the way, if it weren't for his introduction, maybe Han Yaochang would have gone bankrupt now after burning money.

"Study hard and win glory for the country in the future. Also, you have a lot of ready-made teachers, remember to review your homework, the final exam is coming soon. ”

If you want to go further, receiving a university education is a necessary condition, and Jiang Zhaoping hopes that Han Hao will go further in the future, so he does not forget to urge him to study university courses.

"Thank you Director Jiang for your teachings, I will definitely live up to your expectations. ”

When the 70CC engine passed the acceptance, Han Hao began to face the next problem, which was how to transform intellectual property into commercial results. To mass-produce 70cc engines, he had to build an industrial engine production line, but now he can't afford to invest millions more in building a factory.

The test is coming again, and Han Hao will face another challenge in his life.
