Chapter 87 Engine Testing
He only knew that he was helping to modify the mold. Then, after pouring, he helped with the simple processing. Zhu Xuefeng took the parts to toss with, and after he came out, he would help again. Once you finish it, you're qualified.
The key is to save trouble. According to Xiao Zhu, it is really strange that the rear cylinder and piston can maintain this level.
“Here, are all the parts ready?”
Master Xie chuckled,
“You asked Section Chief Lu for all these things, and we got them all. He is also in the office, and the leaders of our technical department all want to take a look."
It seemed that he couldn't escape, so Zhu Xuefeng had no choice but to nod.
"Okay, you ask them to bring all the things over, and I will assemble one and try it."
"Good boy, just waiting for your words, my heart is scratching my head. It’s been 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. Zhu Xuefeng greeted him affectionately.
"Uncle Lu, I see you have been alarmed again. I just came to see the progress. Master Xie and the others are too enthusiastic and have to see the real thing."
Section Chief Lu also laughed. , 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, this matter Why does it seem to be derailed, the technical department is also here.
It turns out that after Zhu Xuefeng left the day before yesterday, the designer from the Polytechnic University came. By chance, he saw Zhu Xuefeng's cylinder block and piston. They were so exquisite.
It can be easily held with one hand. It is very beautiful, not like an engine, but like a handicraft. It is strange 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. He asked many people, but 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.
For the first time of assembly, Zhu Xuefeng was not very skilled. 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 is very delicate and very small. Master Xie cannot believe that this thing can really be made. Although he is 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?"
Looking at the suspicious eyes of everyone, Zhu Xuefeng was a little proud and wanted to see the specific operation situation.
“Buy a hammer, what a joke, our motorcycle factory can save you a mouthful of gasoline!”
For this little guy, a mouthful of gasoline can probably burn for a long time.
Zhu Xuefeng took advantage of the time to get the oil and checked again to confirm that there was no problem. Connect the oil pipe and wait.
After a while, a few people came over, carrying some things to do. Without Zhu Xuefeng, 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. I didn’t expect that someone would bring me engine oil without me, and I almost burned out.
Zhu Xuefeng looked at Section Chief Lu, a little strange, where did these people come from? Section Chief Lu also looked at Zhu Xuefeng.
"They are all from the technical department and assembly workshop. Maybe they just want to see if your gadget can work." There was a slight roar and the engine started. Everyone looked at it as if they were surprised. It’s such a gadget, I really can’t understand it. It’s too small. Think about today’s tractors. The size of the engine is called an engine. Such a gadget can really move.
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. , as if he didn’t believe that the little baby in his hands could breathe on his own, and always wanted to check his nose to see if he was still breathing out.
The engine works very stably, runs very smoothly, and the sound is very small. There is only a faint black smoke emitted, reminding everyone that this thing is really an engine, powered by gasoline.
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’s 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's too small, look at the size and strength of their tractor, it's called an Iron Bull.
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. Let's see tomorrow. How are the other accessories?"
The two walked into the road chatting. The section chief's office.
"Xiao Zhu, tell me, can this thing of yours really run?"
Section Chief Lu is the most supportive of Zhu Xuefeng's realization of his idea, but he is still a little doubtful. In everyone's eyes, this is Like a toy.
The displacement designed by Zhu Xuefeng is about 60CC. It is air-cooled and the power under normal conditions is about 3.5 to 4.2 horsepower. The peak value can reach nearly 8 horsepower at 7000 rpm, which is very powerful. (Far lower than the Honda 50CC a few years later)
The designed maximum speed is about 40 to 45 kilometers per hour, and the top speed should be more than 70. These are theoretical data. In fact, it should be slightly lower. It seems now Maybe a little lower.
But there will be no problem at all when running. This is designed with reference to Zhu Xuefeng’s childhood motorcycle that came from the seaside, and combined with the small-displacement scooter motorcycles of later generations.
The engine displacement is 20% larger than that of later generations, and its capacity should be almost the same as the 50CC of later generations.
"Uncle Lu, there must be no problem. When the wheels come 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 was surprised at Section Chief Lu's performance. A straightforward man could still hesitate.
“Didn’t you make two of them? If you can really run, give the second one to me first, and then I will make another one for you.”
Chief Lu has seen the overall effect. The picture is very beautiful, the appearance has never been seen before.
"Uncle Lu, you'd better wait. You want my aunt to use it, right? She works too far away."
After Zhu Xuefeng broke it off, Section Chief Lu was not embarrassed. The two have collaborated many times, and Zhu Xuefeng has already met his wife.
"You are not a stingy person. Is there still a problem? Can't you use it?"
Zhu Xuefeng looked at Section Chief Lu, handed a cigarette, lit it, and lit it himself He took one and blew out the smoke.
"Uncle Lu, when this thing comes out, it needs to be tested and tested. The brakes, the engine, everything needs to be tested on the road. Otherwise, there will be trouble."
"When this thing runs, It should be faster than buses and trams. If you don’t try it, do you dare to let my aunt ride?”
“Besides, there’s not even a sign on it, this...”
