The ups and downs of life in the Siheyuan

Lu Xingyu's answer gave Li Yuan the urge to cover his face.

"Boss, don't you want to get a diesel engine that can actually start?"

"That thing is so expensive, how is it possible...".

He stopped suddenly and stared at the parts on the table.

Li Yuan was delighted.

"It would be great if we could have such a small real thing," he actually lamented.

"Leader, actually, our factory has the materials to make these parts. Do you want me to get you a real one?"

"Isn't this bad?!".

Looking at his ready-to-move expression, Li Yuan knew it.

Li Yuan could see that the leader in front of him didn't think about products at all, it was just the innate liking of men.

After thinking about this, he thought about guiding him to make a sample first.

If the system is triggered by then, all these efforts will not be in vain.

"Leader, these things don't cost much material anyway. Making a real thing that can be activated will definitely be exciting.

If you think about it then, if you take out this wooden model, people who see it will definitely not believe that it can be used.

If you take out the real thing again and activate it like this, what effect will it have?"

Little stars appeared in Lu Xingyu's eyes.

However, within ten seconds, his eyes slowly returned to clarity.

He looked at Li Yuan with a half-smile, "Tell me, what evil are you holding back?"

"Hey, no way! But recently I have been thinking that if our machinery factory keeps producing wrenches, it will be easily imitated by other big manufacturers.

With their manufacturing capabilities, we will be unable to fight back.

So I thought about doing something difficult.

In the past few years, I have been studying engine principles by myself. At the previous stage, I got a detailed explanation of engine principles, so I wanted to design an engine suitable for domestic use.

The great man said in the first half of the year: The fundamental solution for agriculture lies in mechanization.

We must not follow closely?

Now we are all imported large tractors, which are still in the imitation stage.

The core component, the engine, is an early design with complex structure, high fuel consumption, and difficult maintenance.

And as far as I know, there is no domestic engine of its own yet.

Although there are hundreds of tractors in China, none of them have their own engines.

The heart of a tractor is the engine. It is so sad to not have its own engine."

Lu Xingyu was tempted by Li Yuanshuo.

"Can you really do this? Can you really activate it?"

"I don't know, but there must be no first step in doing anything."

He lowered his head and thought for a long time.

"How sure are you?"

"Give me half a year, I dare not say %, but there is still hope for %."

"Done!".

Lu Xingyu is young, and he has the final say in this factory now.

The popularity of the card wrench has already enabled him to submit a satisfactory answer to the head office.

If he can come up with an engine, he can gain deep capital.

After thinking about this, why is he still hesitating?

The big deal is just a waste of materials, which is harmless.

"Can your engine be used on a large tractor?"

Nowadays, people like big things, and many tractors are still crawler-type.

“Nowadays, the vast majority of rural areas, especially in the south, do not actually have access to large agricultural machinery.

This engine of mine is specifically aimed at small agricultural machinery, which can pull goods, plow fields, and run freely on sandy roads."

He had spent time in rural areas and felt the same way when he thought about the farmland layout in northern Shaanxi.

"Just go ahead and do it. If you need anything, just ask and I will take care of it for you."

Once he made up his mind, Lu Xingyu was very generous.

"It doesn't have to be so troublesome. I'll design the mold first and then ask the foundry to make it by hand.

I can do it myself in the later stages of refinement.

But you need to buy some bearings, sealing steel rings and steel tiles."

"There is no problem with this. I have leaders I know at the Red Star Rolling Mill who will help you get it done when the time comes."

"Okay, I'll modify the drawings first and send them to you in a few days."

More than ten days later, Li Yuan gave Lu Xingyu the repeatedly calculated parts drawings and asked him to help with procurement.

Then I went to the mold shop and started making molds for casting.

The current mold workshop director is a very kind young man. He doesn't understand molds, so he relies heavily on Li Yuan.

The technical leader trained by Li Yuanbang's mold workshop is the ingenious Liang Zhixiang.

Although there is no master-disciple status, it is better than master-disciple.

It is precisely because of his upright character that he is dedicated, serious and responsible.

He quickly became Li Yuan's right-hand man when it came to assembling bicycles.

During this organizational reform, Li Yuan brought him to the mold workshop.

Although innovation is insufficient, imitation and persistence are enough.

The main parts that need to be cast in the engine include:

Engine main frame, housing, crankshaft, pistons, valves, counterweight flywheel, water tank and camshaft.

After casting is completed and finishing is completed, it can be used normally.

As for the fuel injectors, he plans to purchase them directly.

Li Yuan made the mold himself, and Liang Zhixiang helped.

Explaining while doing it, I hope he can master the key points of mold making of such complex parts as soon as possible.

One month later, all the accessories were placed in Li Yuan's office.

In Li Yuan's office, there is a large solid wood workbench that he made by himself.

At that time, Lu Xingyu laughed at him for a few days, but it also established his image as a doer.

Li Yuan took Yan Jiecheng to start assembly.

One more thing to say here.

At Yan Jiecheng's request, Li Yuan transferred him to the mold workshop.

In fact, it is to train subordinates for future technical departments.

When designing parts, Li Yuan repeatedly determined the dimensions, so there were no dimensional matching problems during assembly.

Basically it's a success.

Yan Jiecheng followed and recorded the installation steps and design defects to facilitate Li Yuan's later improvements.

At the same time, Yan Jiecheng needs to organize it into an assembly manual.

Li Yuan has already compiled the assembly manual template.

In just one day, a single-cylinder diesel standard 1-stroke engine appeared on the workbench.

Li Yuan turned the external counterweight and put his ear against the casing. There was no abnormal sound from the engine.

After adding engine oil, diesel and cooling water, Li Yuan slowly shook the crank.

Slowly feel the rotation of the engine, it is extremely smooth.

Shake it hard, keep increasing the speed, suddenly release the pressure reducing valve with your left hand, and the engine starts suddenly.

Although the engine vibrates obviously, it is indeed a standard engine.

The engine in front of you is 10 times larger than the previous model.

Li Yuan got it right in one step and directly aimed at practicality.

Standard 12 horsepower, 8.8 kilowatt small engine.

Run it for a while and the engine has no issues.

But Li Yuan had to turn off the engine because the exhaust gas from the engine had filled the entire room.

Hearing the noise, Lu Xingyu and other workshop directors ran over and were startled as soon as they opened the door.

"Xiao Li, are you okay?"

As soon as he finished speaking, Li Yuan walked out of the black smoke. His face was dark with oil and smoke.

Li Yuan bared his teeth and said, "It's okay, the engine is successful."

Upon hearing what he said, Lu Xingyu was the first to rush into the room, regardless of the exhaust fumes in the room.

When they saw the engine on the table clearly, they were not only shocked but also excited.
