"Boss, after our efforts, we have tried to produce a prototype. We are now testing it. There are many problems, and the main mechanical problems have not achieved the best combustion conditions."

Miao Wei carefully answered Wang Yong’s question.

It is not difficult to test-made an engine. Draw a design drawing and use a five-axis linked CNC combined machine tool to make the parts one by one. When combined, it will be an engine.

However, Dolphin Technology is different from other automobile companies. It does not have a complete supply chain of parts, and all parts are developed by itself.

There are too many problems in this. A screw or a spring must be found, otherwise problems will occur frequently.

The engines that Miao Wei's team have now been tested are just like this. After their efforts and improvements, they can barely start and go on strike at any time. There are a lot of problems anyway, so Wang Yong asked him, and Miao Wei was not confident in speaking.

"Is it because of insufficient manpower?"

Wang Yong was not angry, but his tone was very serious.

Miao Wei was a little panicked and quickly apologized: "No, no! Sorry! Boss, we have been entering this field for the first time, and we are inevitably inadequate in our experience and have inappropriate considerations. Now all kinds of parts are not qualified, and we are still improving."

"What are the problems? Tell me about it." Wang Yong continued to ask him lukewarmly.

"The main problem is the various springs and crankshafts. We have not found the best value yet, which causes the machinery to be poorly matched and it is easy to shut down." Miao Wei told the truth.

Miao Wei and his team are less experienced than ordinary automotive engine R&D teams, but their advantages are also obvious.

As for materials, they use the best imported materials. From the inside to the outside, they are all imported materials and have the most precise machining technology. With these two points alone, the starting point is very high.

Wang Yong also reminded them to learn other engine design ideas and pay attention to the difference in parts and components, so there is no big problem with the engine design.

Like gears and bearings, there is no problem, and the performance is excellent and smooth, but it is not durable due to the problem of the tempering process and cannot reach the service life of similar parts abroad.

But these do not affect the performance of the engine. The most annoying thing now is the small parts such as screws and springs.

Screws are a problem of tension and tightening, while springs are a problem of elastic modulus, and require continuous debugging.

It was these small problems that caused the engine to be like a diesel engine, with loud noises and thick smoke, and it would be shut down after a few sounds. It was simply terrible.

Because there are too many problems, Miao Wei and the others have not yet had the time to study fuel management technology.

This is the disadvantage of not having a foundation. If an ordinary three-cylinder engine is used as a basis for improvement, it will be much easier.

It is normal for a new product to have problems. Wang Yong was not angry, but he also discovered the problem and instructed: "You only made one engine to study how to study it. You need to speed up the process and try to make a few more. If you don't have ten machines, just twenty machines will be. Once there are more engines, the faster the data will be collected.

I can tell you that this engine is another product that our company can use commercially at this stage.

You must work harder and seize the time to perfect the engine. You can go down!"

"Yes" Miao Wei bowed respectfully and turned around and left.

It is not that easy to build a car engine. When Europe and the United States invented gasoline engines, their performance was poor, and the situation was similar to Miao Wei and others.

After hundreds of years of research and improvement, we have now achieved the engine with excellent performance. Not to mention many, just adjusting the valve gap is a profound technology.

Miao Wei’s team is all laymen, so of course they have to pay the price of learning.

What Miao Wei and the others lack now is metal quenching technology. The springs produced are not up to standard, either too hard, too brittle or too soft, which is really a waste of the good materials.

Some people may think that springs can be bought ready-made, but they have actually tried it. Because it is a brand new engine with no supporting parts, the ready-made springs do not match and need to be developed by themselves.

What they are poor now is the tempering process, not the specifications of parts. This problem is not unsolvable, but it is just time-consuming.

Miao Wei’s team shares an experimental factory with Zhang Zhidong’s team and Zhu Tao’s team.

It has been eight or nine months since its establishment at the beginning of the year. They have purchased equipment bit by bit from the poor and backward basis to form a set of test production equipment.

Although they have few people, they have the most production equipment, such as oil molding die casting machines, tempering furnaces, annealing furnaces, five-axis linkage combination machine tools, etc.

These big guys are very large, and their team of 15 people accounts for half of the entire factory building.

When Miao Wei returned to the experimental factory, the noisy scene of people rushing in the past disappeared, and only the people in their group were still there.

The people from Zhang Zhidong's team and Zhu Tao's team have new tasks at this time, and they have moved back to the temporary office building in the dormitory area to work.

Everyone was busy doing the experiment at hand, but they didn't see Miao Wei coming in. Miao Wei walked straight to several technicians next to the tempering furnace and asked a leading master in his forties and said, "Old Li, has the valve spring progressed?"

Several people were discussing the issue seriously, and even Miao Wei didn't know that when he arrived, Miao Wei spoke. Several people turned around and saw that it was him. The old Master Li immediately answered him: "Manager Miao, the situation is much better, but it is a bit rigid and not durable. We are discussing how to improve it."

"Old Li, and you guys, I want to tell you something. The boss called me away just now and was very dissatisfied with the progress of our project.

We need to speed up the development of the time. Testing one engine is too delayed. First, we will try to produce ten units to speed up the pace of the experiment.”

Miao Wei had a serious face and issued a rare tone to command to several technicians.

These technicians are relatively old and come from the bankrupt state-owned machinery industry. They have rich experience in machining, but are not good at metal quenching and tempering. They have only seen technicians do these things.

They also drove the ducks to put them on the shelves. Now, looking at Miao Wei's appearance, they also knew that the boss had any objections, and a few masters immediately panicked.

Lao Li agreed immediately. "Okay, Manager Miao, let's do it right away."

Don’t blame them for panic. You may not know the embarrassment of state-owned factories in the 1990s. A whole family lived in a tube building, only one room, without kitchen and toilet facilities, and the conditions were very simple.

Since they joined the company and lived in a single dormitory like a five-star hotel, they were almost in heaven, so they immediately took their families to the company to live in.

They are older and their children can find jobs. They are not afraid of having nothing to do in Yangcheng. Moreover, their technician level is high, at least level five or above, and their salary is at least above 3,000, ten times their previous experience.

Even if the family doesn’t do anything, it’s enough to bear it. Unlike such young employees, they all take care of their families and have such a good job, they don’t want to lose it!

The boss is unhappy. The unlucky one is the ordinary technicians, so it’s no wonder they are scared.

There are ready-made drawings and CNC machine tools, which quickly process parts. In just two days, several technicians assembled ten brand new engines.

Not only that, under Miao Wei's repeated resolute efforts, the entire team immediately moved at high speed, worked overtime to do experiments, and the R&D speed suddenly increased by more than three times.
