After idling for more than an hour without any malfunctions, the machine was stopped, all parts were disassembled, and all components were inspected.
After assembly, it was run on the experimental platform for 10 hours, 48 hours, and 100 hours.
Every certain period of time, it is necessary to check and confirm the degree of wear and tear.
He Yuzhu only installed the engine on the Jeep after it had run for 500 hours.
The copied engine was named Limin 100 by He Yuzhu. The engine's power was twice that of the M20 engine produced by Jinling Engine Factory.
When placed on a Jeep, it significantly improves the vehicle's performance, both in terms of power and off-road capability.
Factory Director Shen said, "It seems that this change is feasible."
"Yes, the hard work of the past two months has paid off. We have finally produced our own engine, which gives us the ability to produce Jeeps."
News has come from Shanghai this year that production of the Type 58 Jeep has been suspended due to engine defects and numerous other problems with the vehicle.
After extensive deliberation, it was finally decided to cancel the project.
He Yuzhu quietly and efficiently completed the production of the replica engine, which was a significant step forward.
At that time, there was no intellectual property right, so once you got the other party's engine, you could copy it and produce it.
The most obvious example is the 130 truck, which became famous in later generations. Dozens of automobile companies across the country could produce it.
What are Yuejin 130, Shanghai 130, and Beijing 130? Apart from the brand, the appearance and engine of the whole vehicle are exactly the same.
Whether or not they can be produced depends on their individual abilities.
Director Zhu attaches great importance to engine production and calls to inquire about it almost every day.
When he learned from He Yuzhu that the 500-hour verification had been completed, he couldn't sit still.
Tell He Yuzhu to wait, saying, "I'll be right there." He Yuzhu then pulled Lü Xiaomi aside and discussed work in the office for a while before going to pick up the person.
Director Zhu didn't waste any words and said directly, "Take me to see the engine."
He Yuzhu led him into a shed where a large frame was fixed on the ground, and three engines were mounted on it, making a roaring sound.
何雨柱介绍说：“1号发动机已经平稳运行了600多小时，2号发动机不到400个小时，3号发动机只有80个小时左右。”
Director Zhu asked, "Was there any major repair done in between?"
"Of course not, it's just a minor design flaw. We haven't been able to remove the cylinder head even after several minor repairs."
Director Zhu nodded: "So the engine is fine."
After inspecting the three test engines, He Yuzhu invited him to the test track.
"The engine in the Jeep is running normally."
"Stop, I'll go up and try it."
He Yuzhu naturally obeyed Director Zhu's orders. He had the test driver stop the jeep, and then Director Zhu sat directly in the driver's seat, while He Yuzhu quickly got into the passenger seat.
Director Zhu started the jeep, drove it around the test track twice, and then drove it out of the machinery factory.
Then he said, "Oh, right, I have to go to the steel rolling mill. Let's go together."
"Ok."
Since the cars were already on the road, He Yuzhu had no reason to refuse. On the way, Director Zhu asked about the assembly of the 30 cars.
Previously, a total of 50 sets of complete vehicle parts were purchased, of which only 20 sets were engines. The remaining 30 sets will use the Limin 100 engine produced by ourselves.
He Yuzhu said, "Ten vehicles have already been assembled, and we are currently assembling one vehicle per day."
This speed may sound slow, but even last year, Shanghai only produced 498 cars.
Moreover, the demand is not high now, since there is no certain level of social status that allows one to be equipped with a car, and private individuals are not qualified to purchase one; only organizations can afford it.
Producing too much is also inappropriate.
Moreover, this is currently in trial production, and it will take time to confirm the engine's performance and lifespan.
He Yuzhu continued, "After assembling these 30 vehicles, we will use parts produced by ourselves. Of course, we will not modify them all at once, but gradually replace them."
After the parts are manufactured, they must be inspected. However, the replacement process should be carried out slowly and not rushed.
"Things need to be done slowly."
Director Zhu said, "However, I will take all ten vehicles that have already been produced."
There was no problem with that, and He Yuzhu agreed immediately.
Now the machinery factory is a production base, and Director Zhu can handle all the sales, so He Yuzhu doesn't need to worry about it at all.
In those days, this was a drawback. Back then, the economy was planned, and factories didn't have sales departments; most factories only had purchasing departments.
They soon drove to the steel rolling mill, where the two were invited into Director Yang's office.
Director Yang was quite surprised to see He Yuzhu coming with Director Zhu.
Director Zhu said, "Never mind him, I'm here to check on the production of spring steel plates."
Factory Director Yang asked first, "He Yuzhu, are you eyeing our spring steel plate workshop? Let me tell you, we let it go last time you tried to go to the auto repair shop, but you absolutely cannot try to take advantage of our factory again."
"Even if we take it to the top leaders, they won't take our workshop back. We won't give it to them no matter what."
After hearing this, He Yuzhu said, "I really didn't mean that."
Leaf springs are a very important component in automobiles, especially trucks, where they are indispensable.
Leaf springs are flat, rectangular steel plates that are bent into a curved shape. Several leaf springs are stacked together to form a chassis. One end is mounted on a hanger with a pin, and the other end is connected to the main beam with a lifting lug, allowing the leaf springs to extend and retract. Currently, they are used in off-road vehicles and medium to large-sized trucks.
Factory Director Yang thought that He Yuzhu had set his sights on the spring steel plate workshop again and wanted to take it away directly.
Director Zhu just shook his head and smiled, saying, "This time it really isn't. I just went to the machinery factory to inspect their Limin 100 engine, and then brought He Yuzhu to talk to you about the production of spring steel plates."
Factory Director Yang was still somewhat suspicious, but he didn't ask any further questions and led the two of them to the spring steel plate production workshop.
The first Jiefang brand truck in China is currently being produced in Kunming, and the steel rolling mill is supplying them with spring steel plates.
He Yuzhu's company also manufactures Jeeps. There's a demand for leaf springs from them.
After visiting the spring steel plate workshop, the three went to the office, where Director Zhu listened to a report on spring steel plate production and discussed the technical issues involved.
The research institute also needs to optimize the production process.
Then they brought up the matter of having the steel rolling mill produce spring steel plates for Jeep vehicles.
Only then did Factory Director Yang feel somewhat relieved, knowing that they hadn't come to seize his workshop.
After discussing spring steel plates, the conversation turned to the production of automobile chassis, as well as some large components on the front and rear axles, which all need to be manufactured by steel rolling mills.
It's not that there aren't factories in other places that can produce it, but the distance is too far and transportation is a major problem.
For small batches of a few dozen, it's acceptable to purchase from other places. However, for longer periods, it's best to produce locally as much as possible to save on transportation costs.
Factory Director Yang asked, "Was your Jeep modification project really a success?"
He Yuzhu said, "Of course, the new Jeep is downstairs."
"Come on, I want to see it with my own eyes."
Before we could even mention this, Director Yang came downstairs, opened the hood, and immediately recognized a brand-new engine inside.
The steel mill also had two Type 58 jeeps, but they had too many minor problems and were often broken down on the road.
Factory Director Yang certainly recognized the original M20 engine.
The engine in front of us is clearly a size bigger now.
He Yuzhu said, "This engine is a copy of the one used in the GAZ-100 sedan, and it looks much better than the original M20 engine."
Factory Director Yang nodded: "If possible, we will purchase five new Jeeps."
Chapter 321 Why aren't you getting up?
"So much?" He Yuzhu asked.
Factory Director Yang said, "We have several branch factories that are qualified to be equipped with jeeps, but the Type 58 jeeps are too easy to break down, so we didn't continue to purchase them after buying two."
He Yuzhu didn't ask any more questions. It was good that they could be sold. Each Jeep could earn more than 2000 yuan.
After replacing the parts, the procurement costs will be significantly reduced.
After negotiating the purchase of some parts at the steel rolling mill, I returned to the machinery factory with Director Zhu.
After Director Zhu and his group left, He Yuzhu also entered research mode.
He and his workers spent every day on the production line, constantly improving the assembly line, and their own factory gradually began producing various parts to replace the previously purchased components.
Although a planned economy is in place now, there are no mandatory requirements for collective enterprises.
He Yuzhu was willing to stay in the collective period because he had a certain degree of independence.
At that time, the state only issued production plans to factories with higher levels and carried out planned production for them, but there was no document stipulating how much product collective enterprises should produce.
Because typical collective enterprises are small factories with only a few dozen or even just a few people.
Director Li Hongying is very open-minded and trusts He Yuzhu, allowing him to develop his career freely, only accepting leadership from the street office.
As Jeeps rolled off the production line, the original stock of parts was gradually used up. The fifty Jeeps were successfully delivered, and the next batch of production consisted entirely of replacement parts.
After actual testing, it was found that the new vehicle had a significantly reduced failure rate and more powerful performance, which finally put He Yuzhu at ease.
