"The main problem is that we haven’t found the optimal value of various springs and crankshafts, which leads to poor mechanical fit and easy flameout." Miao Wei told the truth

Miao Wei, their experience is not as good as that of the general automobile engine R&D team, but their advantages are also obvious
That is to say, they are all the best imported materials, imported materials from the inside out and the most sophisticated machining technology. Only these two points have a high starting point.
Wang Yong woke up again. They studied other engine design ideas, and paid attention to the difference of parts. There was not much problem in engine design.
Like gears and bearings, there is no problem. The excellent performance is smooth because of the quenching and tempering process, which leads to the failure to reach the service life of similar parts abroad.
But these do not affect the performance of the engine. Now the most annoying thing is the small parts such as screws and springs.
The screw is loose and tight, and the spring is elastic modulus, which needs constant debugging.
It is these small problems that make the engine ring like a diesel engine, and it is terrible to stop the engine after a few loud noises.
Because there are too many problems in Miao Wei, they haven’t had time to study fuel management technology yet.
This is the disadvantage that there is no foundation. It will be much easier if there is an ordinary three-cylinder engine with improved foundation.
It’s normal for a new product to have problems. Wang Yong wasn’t angry, but he also found the problems, so he instructed, "You made an engine to study how to speed up the process. If you don’t have ten engines, you will have twenty engines. The faster the data will be."
I can tell you that this engine is another product that our company can negotiate at this stage.
You have to work harder to improve the engine when you hurry. You go! "
"Yes" Miao Wei bowed respectfully and turned and excused himself.
It’s not that easy to build a car engine. When Europe and the United States issued gasoline engines, their performance was also poor, and the situation was similar to that in Miao Wei.
After a hundred years of research and improvement, the engine with excellent performance today is a profound technology, not to mention much.
Miao Wei’s team is a layman, of course, at the cost of learning.
At present, what they lack in Miao Wei is the performance of springs made by metal quenching and tempering technology, but they are either too hard, too brittle or too soft, which really blinds those good materials.
Some people may think that the spring can be bought off-the-shelf, and they have tried it, because the newly designed engine has no matching parts, and the off-the-shelf spring needs to be developed by themselves.
Now their difference is the quenching and tempering process, not the part specification. This problem is not the solution but the comparison time.
Team Miao Wei is an experimental workshop with team Zhang Zhidong and team Zhu Tao.
From its establishment at the beginning of the year to now, nine months later, they only added equipment bit by bit from a poor foundation to form a set of experimental production equipment.
Although they are few in number, they can produce equipment, but most of them are like oil die casting machines, tempering furnaces, annealing furnaces, five-axis combined machine tools and so on.
These big guys are huge, and their 15-person team accounts for half of the whole factory.
When Miao Wei returned to the experimental factory, the crowds and noise in the past disappeared, leaving only his group.
Zhang Zhidong team Zhu Tao team members are all new at this time, and they have all moved back to the temporary office building in the dormitory area.
Everyone was busy doing the experiment at hand. I didn’t see Miao Wei coming to Miao Wei. He went straight to several technicians next to the tempering furnace and asked the leading teacher in his forties, "Is there any progress in Lao Li’s valve spring?"
A few people are seriously discussing the problem. Even Miao Wei didn’t know that he was around. A few people in Miao Wei turned around and saw that it was his Lao Li master Ma who answered him, "Manager Miao’s situation is much better, but it is still a little rigid. We are discussing how to improve it."
"Lao Li and you guys, I want to tell you one thing. The boss just called me to be very dissatisfied with the progress of our project.
We have to speed up the development of an engine, and when the test is too late, we will try out ten engines first to speed up the experiment. "
Miao Wei issued a rare command tone to several technicians with a serious face.
Most of these technicians are older and come from the closed state-owned machinery industry. They are experienced in machining but not good at metal tempering. I have seen technicians do these things.
They are also chasing ducks. Now they see Miao Wei. They also know that the boss has a crush on several Lao shifu and immediately panicked.
Lao Li Ma replied, "Good Miao Manager, let’s do it."
Don’t blame them for their panic. You may not know the embarrassing situation of state-owned factories in the 1990 s. A large family lives in a tube building with one room and no kitchen and toilet. The supporting conditions are very simple
Since they joined the company, they have lived in a single dormitory like a five-star hotel. It is suspected that they have taken their families to the company since they arrived in heaven.
They are all older, and children can also find jobs. Yangcheng is not afraid of nothing to do. Besides, their mechanic level is high or low, and their salary is at least three times that of their top ten.
Even if the family doesn’t do anything, it’s enough to bear the burden. They are different from so young people. The staff are all in married with children and they are such good jobs. They don’t want to lose them!
The boss is unhappy and unlucky, even they ordinary mechanics, so it is no wonder that they are afraid.
There are ready-made drawings and CNC machine tools to process parts, and in two days, several technicians assembled ten brand-new engines.
Not only did some Miao Wei repeatedly urge the whole team to move at high speed and work overtime to do experiments, but the speed of research and development suddenly tripled.

It’s really to blame, and it’s also to blame that dolphin’s scientific and technological conditions are too simple to develop automobile engines.
That is to say, the spring test should have a special test equipment Miao Wei team. It is of course a waste of time to save money by directly loading it into the engine test.
However, after many failures, these technicians finally found the metal tempering method, and the spring made is getting closer and closer to the ideal value.
The specific performance is that the engine can keep running for a long time without stalling.
Of course, there are still many problems, such as loud noise and heavy smoke, which have not changed
At this time, it is necessary to adjust the valve clearance. This step is not difficult to adjust slowly with a screwdriver and a wrench.
