Restarting life in Siheyuan

Chapter 88 Engine Test

All he knew was that he was helping to constantly modify the mold. Then, after pouring, he helped with some simple processing. Zhu Xuefeng took the parts to fiddle with. After they came out, he helped to finish them off and it was qualified.

The key is to save trouble. According to Xiao Zhu, it is really strange that the cylinder and piston at the back can maintain this level.

"Here, all the parts are working?"

Master Xie smiled and said,
"We got all these things from Section Chief Lu. He is also in the office, as well as the leaders of our technical department. They all want to take a look."

Seemingly unable to escape, Zhu Xuefeng had no choice but to nod.

"Okay, you ask them to bring everything over, and I'll try to assemble one."

"Good boy, I've been waiting for your words, and my heart has been scratching my head all morning."

Master Xie went to pick up the parts with a smile, and even asked someone to ask Section Chief Lu to come over.

In the assembly workshop, I found a place where Zhu Xuefeng was squatting on the ground and assembling piece by piece. Without the assembly diagram, no one could assemble it, except Zhu Xuefeng.

Section Chief Lu also came. This matter really bothered him a lot, so Zhu Xuefeng greeted him affectionately.

"Uncle Lu, I see you have been alarmed again. I just came to see the progress. Thank you, Master, for they are too enthusiastic and insist on seeing the real thing."

Section Chief Lu also laughed and hugged Zhu Xuefeng's shoulders.

"Well, not only him, but also the leaders of our technical department want to see it. This is Section Chief Wang of our technical department."

Zhu Xuefeng stood up quickly and said hello. Why did this matter seem to be derailed? The technical department also came.

It turned out that after Zhu Xuefeng left the day before yesterday, the designer from the Polytechnic University came and happened to see Zhu Xuefeng's cylinder block and piston. These things were so exquisite.

It can be easily held with one hand. It is very beautiful, not like an engine, but like a handicraft. I wonder how a motorcycle factory can make a cylinder with such a small cavity and no power output.

The workers on the side handed over Zhu Xuefeng's drawings. The designer of the University of Science and Technology became more and more surprised and strange as he looked at it. After asking many people, he still didn't understand.

According to the requirements of the drawing, it cannot be processed at all now. According to the capacity of the cylinder, it should be very small and of little use value.

Only then did everyone want to see the real thing.

Zhu Xuefeng was not very proficient in assembling for the first time. Fortunately, the craftsmanship of the masters was still very reliable and they could all meet the requirements of the drawings.

Some unexpected aspects of the design were modified directly in the workshop. In more than an hour, a mysterious ultra-small gasoline engine was presented to everyone.

It's very delicate and very small. Master Xie can't believe that this thing can really be made. Although he was involved in the main modifications, can this thing work?

It is countless sizes smaller than the engine in our factory, and its appearance is like the difference between a peanut and an egg.

"Chief Lu, can you buy some gasoline to try?"

Seeing everyone's suspicious eyes, Zhu Xuefeng felt a little proud and wanted to see the specific operation.

"Buy a hammer, what a joke, our motorcycle factory can save you a mouthful of gasoline!"

This little thing, a mouthful of gasoline can probably burn it for a long time.

Zhu Xuefeng took advantage of the time to get oil and checked again to confirm that there was no problem.Connect the oil pipe and wait.

After a while, several people came over, carrying some things. Zhu Xuefeng didn't need to do anything. Some people added engine oil, some connected the oil pipes, and some checked the gas lines. Section Chief Wang was personally responsible for ignition.

I was really neglected. If someone came without engine oil, I didn't even think about it, and it almost burned out.

Zhu Xuefeng looked at Section Chief Lu, wondering where these people came from. Section Chief Lu also looked at Zhu Xuefeng.

"They are all from the technical department and the assembly workshop. Maybe they just want to see if this gadget of yours can work." There was a slight roar and the engine started. Everyone looked at such a gadget as if they were surprised. I really understand. No, it's too small. Think about today's tractors. The size of the engine is called an engine. Such a gadget can really move.

Section Chief Wang has circled the small engine several times, wanting to reach out and touch this delicate thing. It really works. He looks like a man who has just become a father and doesn't believe that the baby in his hand can breathe on his own. Yes, I always want to check my nose to see if I am still venting my anger.

The engine works very stably, runs smoothly, and the sound is very low. There is only a faint black smoke emitted, reminding everyone that this thing is really a gasoline engine.

Section Chief Lu was a little nervous just now, but now he was a little surprised and excited, so he punched Zhu Xuefeng.

"Boy, you really did it, it's amazing!"

Although it is strange that this thing can work, everyone still believes in the judgment of the University of Science and Technology that it has no practical value. After all, it is too small. Look at the size and strength of their tractors, it is called an iron cow.

This thing is so small, it can't be called Iron JI, some people laughed...

"Uncle Lu, just throw this away and let it run for a day. We'll see what happens to the other accessories tomorrow."

The two of them chatted and entered Section Chief Lu's office.

"Xiao Zhu, tell me, can this thing of yours really run?"

Chief Lu is the most supportive of Zhu Xuefeng's idea, but he is still a little skeptical. In everyone's eyes, it is like a toy.

朱雪峰设计的排量是60CC左右，风冷、正常情况动力在3.5～4.2马力左右，峰值在7000转能达到接近8个马力，很厉害了。（远低于几年后的本田50CC）

The designed maximum speed is about 40 to 45 kilometers per hour, and the top speed should exceed 70. These are theoretical data. In fact, it should be slightly lower. It seems that it may be even lower now.

But there will be no problem at all when running. This is designed based on Zhu Xuefeng's childhood motorcycles that came from the seaside and combined with later generations of small-displacement scooters.

The engine displacement is 20% larger than that of later generations, and its capacity should be almost the same as that of later generations of 50CC.

"Uncle Lu, there must be no problem. When the wheels arrive in a few days, we can put them on and try again."

"Okay, I believe you. Do you think this will work?"

Chief Lu's eyes were already shining.

"Uncle Lu, tell me if you have anything to say."

I'm surprised by Section Chief Lu's behavior. A straightforward man can still be hesitant.

"Didn't you make two of them? If you can really run, give the second one to me first, and then I'll make one for you."

Section Chief Lu has seen the overall renderings, which are very beautiful, but the appearance has never been seen before.

"Uncle Lu, you'd better wait. You want my aunt to use it. It's too far for her to go to work, right?"

After being told off by Zhu Xuefeng, Section Chief Lu was not embarrassed. The two had cooperated many times, and Zhu Xuefeng had already met his wife.

"You are not a stingy person. Is there still a problem? Can't it be used?"

Zhu Xuefeng looked at Section Chief Lu, handed him a cigarette, lit it, lit one himself, and blew out the smoke.

"Uncle Lu, after this thing comes out, it needs to be tested and experimented. The brakes, the engine, everything needs to be tested on the road. Otherwise, there will be trouble."

"This thing should run faster than buses and trams. If you don't try it, do you dare to let my aunt ride it?"

"Besides, there isn't even a sign, this..."
