Yuan Aiguo's speech paid more attention to reality, and after finishing his speech, he received a long and warm applause from the audience. And then Director Sun's final speech was empty and had no practical content, and empty slogans were far less tempting than real bread.

Yang Quan was born in a technical identity, and what he hated the most was listening to the leader's speech at the meeting. After an hour of speech, the audience was able to fall asleep, and at the end of the speech, it seemed that everyone could wake up and give an unprecedented round of applause.

I didn't remember a word? It doesn't matter, the leader himself has just made a lot of speeches, and he has not remembered a word of it.

It was almost noon after the meeting, Yang Quan and Yuan Aiguo accepted the lunch invitation and had a light meal with several people in charge in the school cafeteria. It was said that it was a light meal, but it was also thought of, and the chef borrowed it from the automobile factory, so he naturally had nothing to say about the craftsmanship.

Because there was still work in the afternoon, no one drank alcohol at noon, and this meal really filled the stomachs of several people. After the meal, Yang Quan also specially said hello to the chef and got to know him, and saw what a person who can cook sweet and sour pork ribs and braised pork like a delicious one looks like.

After eating, Director Sun of the R&D team said hello to Wu Hao and left, after all, I knew and I knew, and the next thing was to check the actual work.

At half past one in the afternoon, under the guidance of the deputy chief designer of Changzheng, Yang Quan and Yuan Aiguo got to know all the teachers, and learned about the work ability of each teacher and the progress of the project they were responsible for.

Conversation is slow, and it is easy to understand the teacher's ability. Chang Zheng has been in the school for more than ten years, and he gives a pertinent evaluation of each teacher's ability.

But Yang Quan's conversation is actually more about planting seeds and preparing for the development of his company in the future. Yuan Aiguo paid more attention to the progress of the project, asking in detail about the difficulty of the research and what help was needed.

Time flies, and Yang Quan, Yuan Aiguo and Pao have been in the research group for a week. During this week's work, I got to know all the people more than I learned about the progress of the project.

From the bottom of his heart, Yang Quan picked up the treasure this time. In the past ten months, the research group has set up all aspects such as personnel selection, direction selection, and work arrangement, and laid a solid and feasible foundation.

On this basis, the research process has been completed by about 60%. The remaining 40% of the projects will be difficult, but as long as the time and funds are sufficient, these will not be a problem.

Over the course of a week, Yang Quan also found a few troublesome problems.

The first is time, and the other identity of the researchers selected by the project team is teachers. In other words, they are teachers in their own right, and their deputies are members of the study group. Only by ensuring the quality of teaching can they find time to participate in the work of the deputy.

The R&D time is unstable every day, and I can only squeeze it day by day like squeezing toothpaste. Luckily, this has been going on for 10 months, and everyone is used to it and can arrange the work of both parties well.

The second is to be controlled by hardware. This hardware problem refers to the substandard problem of materials, process machinery and equipment.

For example, China is one of the few countries in the world that can manufacture jet fighter engines, but the level of aircraft engines in China is far from being comparable to that of the United States and Russia.

There are not only problems in design level, experience, but also in processing ability. The smelting and processing technology required for engine blades alone is very profound, and it takes a long-term large-scale investment to make it.

However, this does not mean that China can't make aircraft engines, it's just that the level is not as high as that of Europe and the United States, or the cost still can't be reduced.

All in all, compared with developed countries, China's underlying industrial capacity still has many deficiencies. This inadequacy has led to China's industrial base becoming a bottleneck that restricts the further improvement of industrial products.

Again, these don't mean that we can't make products, it's just that the quality and cost control of foreign countries are not as good.

The third is to resign from the school as a teacher, and like Yuan Aiguo, he entered Yang Quan's back garden and chose to work full-time in research and development of engines.

If you want to wear a crown, you must bear it.

This weight is not only the weight of the weight, but also the weight of the pressure.

Chang Zheng was squeezed by Yang Quan's soft knife or designed by Yangmou, and Yang Quan promoted Chang Zheng to the position of deputy chief designer of the design team, and raised his rights and salary.

During this week, I saw not only students who wanted to come over for a piece of the pie, but also retired teachers and relatives who were beating around the bush.

In the school, he has been teaching for a short time, and his status is low, and he belongs to the junior, but in the R&D group, the position belongs to the third place in power, except for Yuan Qingli of the foreign school and the director who does not ask about things, Chang Zheng is the first person in the R&D group in this land!

In the R&D team, you can be a little more serious if you are a superior. But in the academy teaching, it became a subordinate again.

The identities are not equal, and it is not easy to speak.

And no one can ignore the allocation of 50,000 or 60,000 R&D funds per month, and at the conference, Yuan Qingli personally said that Comrade Chang Zheng has certain personnel rights, and everyone has heard this sentence.

Some retired veteran comrades thought that they could still shine for the country and burn themselves, and Chang Zheng asked to join the R&D team. He looked at these old comrades and was also helpless, if you have a professional equivalent, it is good to come in and help, but it is not right to want to come over and sell the old ones if the majors are not equal.

Simply suspended to join the big family described by Yang Quan, the full-time permanent levy is indeed more attentive than before, Yang Quan after thinking about it does not adjust his salary, but increases benefits and bonuses.

Time flies, and R&D doesn't come to fruition in a day or two. Yang Quan unconsciously passed more than half a month here, and after receiving a bad contact from the Wujiacun Bicycle Factory, he put down his work and went to deal with it.

It turned out to be the last two batches of goods, and there were more than a dozen engines with product quality problems, and they were asked to return for exchange and check the reason. Yang Quan returned to the R&D team with a defective product and asked Yuan Qingli to take someone to check it.

Yuan Qingli and Chang Zheng called five or six people to participate in the inspection, and as the saying goes, three stinkers beat Zhuge Liang.

These seven or eight are not soft persimmons, and as soon as the engine sounds, several doubts are immediately locked. After some disassembly and inspection, the cause was directly given, and the quality of the piston ring was unqualified.

A piston ring is a metal ring designed to be embedded in the piston groove, which is assembled into the annular groove with its corresponding profile. Reciprocating and rotating piston rings, relying on the pressure difference of a gas or liquid, create a seal between the outer ring surface and one side of the cylinder and the ring and ring groove.

There are two types of piston rings: compression rings and oil rings. Compression rings are used to seal flammable gas mixtures in the combustion chamber, while oil rings are used to scrape off excess oil from cylinders.

The functions include sealing, adjusting the oil (oil control), heat conduction (heat transfer), and guiding (support). Sealing: It refers to sealing the gas to prevent the gas from the combustion chamber from leaking to the crankcase, controlling the gas leakage to a minimum and improving the thermal efficiency. Air leakage will not only reduce the power of the engine, but also deteriorate the oil, which is the main task of the air ring;

Adjust the engine oil (oil control): scrape off the excess lubricating oil on the cylinder wall, and at the same time make the cylinder wall covered with a thin oil film to ensure the normal lubrication of the cylinder, piston and ring, which is the main task of the oil ring

Contact the factory office of the auto repair plant and ask to immediately check the product status of the last few batches of piston rings. Luo Daodao also knew the seriousness of the matter and found out the cause of the matter within one day.

It turned out that these two batches of goods were purchased from the list of independent manufacturers given by Liu Xiaokang, and the quality of the products of the small factory was unstable, and the quality of these two batches of piston rings was not guaranteed to be completely different from the samples cut.

Luo Daodao also admitted that when leaving the factory, this test was unqualified, resulting in poor outflow and customer complaints.

The reason is known, and the solution is very simple, but the important thing is how to expand horizontally to prevent all products from being like this, which is a difficult problem for Yang Quan.
