I would like to express my sincere gratitude to the book friend qingfeng_gg, Long Shao LL1 for his reward!!

From the point of the educated youth, Su Hongmei quickly forgot the joke of the educated youths just now, and was full of wondering if Yang Weiping could not repair the tractor, whether she should really go to Chen Jialiang.

Seeing Su Hongmei's preoccupied appearance, Yang Weiping didn't know what to say, sighed secretly, walked behind her silently, and soon came to the gate of the production team compound in Shangling Village.

"Uncle Luo, Uncle Luo, I'm Hongmei. Su Hongmei shouted as she knocked on the closed courtyard door.

"Hongmei is here. Old Man Luo came out of the communication room with a fan in his hand and opened the courtyard door with a smile.

"Uncle Luo, thank you. Su Hongmei forced a smile.

The sadness in Su Hongmei's eyes saw that Old Man Luo couldn't help sighing, and comforted: "Meizi, what are you polite to Uncle Luo, come in, I'll watch it for you." ”

"Good evening, Uncle Luo. Yang Weiping said hello to Elder Luo rudely.

Elder Luo nodded, and while closing the courtyard door again, he said: "It is said that you educated youths from the capital have seen the world, and I hope you can bring some good luck to Changgui." ”

"Captain Su is not kind to me, and I will definitely do my best. Yang Weiping said solemnly.

"Alas, it's better to have a glimmer of hope than nothing. Old Man Luo sighed and shook his head, obviously not optimistic that Yang Weiping would be able to repair this tractor that the county engineers could not repair.

Yang Weiping nodded silently, walked straight to the Dongfanghong wheeled tractor parked in the yard, lit the horse lamp in his hand, looked carefully at the head of the machine for a while, and then found the toolbox, motioned Su Hongmei to come over and hold the horse lantern for lighting, and then loosened the fastening cap quite skillfully and opened the chassis shell.

Luo Lao looked at the side for a while, and saw that Yang Weiping didn't look like a layman, so he nodded secretly, handed the fan in his hand to Su Hongmei, and then pouted at Yang Weiping, who was sweating profusely, turned around and left, and went back to drinking.

Su Hongmei held a horse lantern in her left hand, providing lighting according to the places that Yang Weiping kept pointing out, and holding a fan in her right hand to gently fan him.

Because there were no drawings in his hand, Yang Weiping could only explore and scrutinize the two-cylinder horizontal diesel engine in front of him in all aspects.

Although this diesel engine is so simple in Yang Weiping's eyes, he has not been exposed to it for many years, and many details he has to recall according to the real thing.

The technical work is very rigorous, and there must be no sloppiness.

In his last life, Yang Weiping stayed abroad for 20 years, during which he worked as a technical worker at Mercedes-Benz in Germany, a project engineer at BMW, and later as a deputy chief engineer at Rolls-Royce in the United Kingdom. In the mid-nineties, Yang Weiping was hired as a senior engineer by Pratt & Whitney in the United States.

In Pamp; Pratt & Whitney During this period, Yang Weiping participated in the IHPTET plan ("Comprehensive High-performance Worm Gear Engine Technology Plan" in the United States).

In 2001, Yang Weiping was selected by General Electric (Gamp; Electric) for his outstanding performance in IHPTET planning. E) dug to serve as deputy chief engineer. In 2005, there was a leak at General Electric, and Yang Weiping was listed by the FBI and the CIA as a key suspect surveillance target.

After 20 years of lying on the salary and hiding the courage, after several setbacks, Yang Weiping finally returned to the motherland after nearly 20 years of absence in October 2005 under the full mediation of the Chinese government. In December of the same year, Yang Weiping was directly appointed by the No. 1 chief as the general manager and chief engineer of the North Industries Corporation, and at the same time was appointed as the commander-in-chief of the first-generation carrier-based aircraft research and development project in Huaxia.

Although the J-15 was made and the test flight and landing on the Taishan, the first aircraft carrier in China, Yang Weiping did not have time to make further improvements to the J-15, and the illness accumulated from long-term high-load work finally crushed him. Perhaps God was also moved by the obsession in Yang Weiping's heart, and gave Yang Weiping a chance to be reborn for the first time, allowing him to return to 1976. …,

During his work in Mercedes-Benz and BMW, Yang Weiping has deep attainments and research on diesel engine power and gasoline engine power, and has rich theoretical and practical work experience. Although his ultimate goal is aeropower, he knows that the foundation of the road is not solid, and he definitely has no right to speak in the field of engine technology. Therefore, although he did not work on diesel and gasoline engines, he is also one of the world's leading experts in this field.

The two-cylinder diesel engine in front of him, which has an obvious traditional style of Soviet technology, is certainly no stranger to Yang Weiping. But he hasn't been in contact with it for more than 30 years, and for the sake of insurance, he can only start with the most basic maintenance work.

Although there have been technicians who have repeatedly tested the various parts of this diesel engine before, with Yang Weiping's rigorous work style, he will naturally personally see it before it can be regarded as passing.

In this way, of course, the maintenance workload is not light.

Through this meticulous inspection, Yang Weiping also has a comprehensive re-understanding of the diesel engine of this era, and accumulates the most authentic first-hand information in line with the current national conditions for the next entrepreneurship.

Pistons, piston rings, cylinders, connecting rods, valves, oil seals, rocker arms, high-pressure oil pumps and other parts, their materials, design, in Yang Weiping's view, everything is so primitive and backward, there are too many places that can be improved and are worth improving.

Any technical improvement will be an epoch-making utility model technology patent, and each patented technology means a huge wealth.

Yang Weiping compared the current diesel engine with the advanced diesel engine skills in his mind, and suddenly found that there were ownerless gold mines waiting for him to excavate.

Su Hongmei on the side looked at Yang Weiping's focused work demeanor, completely like a professional technician, not at all like a novice who came into contact with tractor maintenance work for the first time, she was both nervous and excited. She was already desperate and had a glimmer of hope, and wanted to ask him out loud several times, but she was worried about disturbing his work.

The sweltering summer night made the beads of sweat on Yang Weiping's head never break, and even the sweat on his back gradually became wet.

Su Hongmei secretly scolded herself for being so careless, why didn't she think about bringing some towels over to wipe his sweat for him!

While increasing the strength of the fan in her right hand to drive away the mosquitoes attracted by the light, she carefully wiped Yang Weiping's forehead with her sleeve.

Seeing that Yang Weiping didn't react, Su Hongmei's nervous heart relaxed slightly.

The diesel engine of the tractor was gradually disassembled by Yang Weiping, and his hands were also stained with oil, occasionally raising his hand to wipe the sweat on his face with the back of his hand, and by the way, his face was also dyed into a cat face.

A gray-spotted mosquito took advantage of Su Hongmei's crispy hand to pause for a while, and unceremoniously stung Yang Weiping's neck, and the originally shriveled belly was immediately filled with blood.

Su Hongmei wanted to shoot this damn mosquito to death, but she was afraid of disturbing Yang Weiping.

Yang Weiping was unaware of this, and carefully reloaded the piston ring into the piston groove, then connected the connecting rod and reset.

Before you know it, time slips away.

After Yang Weiping made a comprehensive search for the power parts of the engine, he determined that all the parts were normal and functional, and he was more confident in repairing the tractor.

There are no problems with the power components, and the next step, naturally, is to check the fuel part of the engine.

As soon as the oil pipeline was removed, I heard the voice of the old man Luo behind me: "Meizi, Xiao Yang Zhiqing, it's not early, it's already past twelve o'clock, you should go back early, this tractor has been dragged for so long and has not been repaired, no matter how anxious you are, it's useless." ”…,

Hearing Elder Luo's greeting, Yang Weiping could only stop what he was doing, straighten his waist, and use the back of his slightly clean hand to kill a mosquito that was biting and sucking blood on his face.

"Excuse me, Uncle Luo, we'll come back tomorrow night. Yang Weiping said apologetically while putting the tractor head shell back into place.

"There's nothing to bother with, it's hot anyway, I can't sleep. Old Man Luo looked at Yang Weiping with curiosity in his eyes and said: "Little Yang Zhiqing, I see that your maintenance techniques just now are not at all rusty with Qian Jilu and Engineer Li, like a veteran, have you also repaired tractors before?"

Yang Weiping tightened the last nail cap, put the toolbox back in its place, and nodded and replied, "Sort of." ”

"Wei Ping, can it be repaired?" Su Hongmei finally asked the sentence that had been held for almost a whole night.

"It shouldn't be a big problem. Yang Weiping found a lump of cotton yarn from the tractor cab and wiped the oil stain in his hand, "Tonight first, as long as there is no fault with the power parts, the fault of this tractor must be a small fault." I'll check the fuel system again tomorrow night, and I guess this is the problem. ”

Looking at the red buds on Yang Weiping's face and neck that were bitten by mosquitoes, Su Hongmei looked at him with guilt, "Weiping, I've tired you." ”

Yang Weiping raised his hand and scratched the itch on his face and neck with the back of his hand, and smiled disappreciatively: "It's okay, the right is to link theory with practice, a good opportunity to learn." Don't worry, Hongmei, I'm sure I'll fix this tractor. ”

"Hmm. Su Hongmei nodded with a wry smile, and there was still half-belief in her big sad eyes.

Although Yang Weiping's hard work tonight gave her a glimmer of hope, she never dared to believe that her life would be so good, any problem could be solved as long as Yang Weiping encountered it, it was related to her father's life, how could she pin all her hopes on Yang Weiping.

Besides, even if the tractor is repaired, her father may not be acquitted, and he will still have to be fined, sentenced, and imprisoned. I really can't do it, so I can only go to the commune to find Chen Jialiang. As long as the father can come back safe and sound, what is there to be sacrificed as a daughter.

When it really came to this day, she could only accept her fate. Is it supposed to be like this, do you blame God? Is that useful?

Regarding Su Hongmei's worries, Yang Weiping can certainly understand. It's just that he doesn't know how to comfort her now, he knows very well in his heart that only by repairing this tractor is the best comfort for her, which is more effective than anything else.

Coming out of the production team compound, Yang Weiping sent Su Hongmei home by the way, returned to the Zhiqing Point, took a bath with cold water by the well, changed into clean clothes and pants, half lay on the kang, carefully recalled the work tonight, analyzed and deliberated on several possible failures in the fuel part, and couldn't sleep for a long time.
