Chapter 453 Install PK (Part 2)

The engineer in charge of recording is very conscientious, and the process records on both sides are very detailed. They not only recorded the operation of each process, but also recorded the installation angle of some specific parts and the tightening torque of some nuts.

On the side of the Mercedes-Benz technical team, these angles or torque values ​​are measured by special instruments, and the records are normal. However, when Guo Tai came to this side, some of the recorded engineers put a question mark.

For example, the installation angle, Guo Tailai installed it according to the design angle. But the recording engineer did not see him measure the angle with any tool, but just saw him reach for the piston and stuff it in. There is a torque wrench for the torque value, but the recording engineer did not see Guo Tai to check the reading, but just reported the value casually.

Therefore, the installation details on Guo Tailai's side were questioned by the two engineers responsible for recording. The data is still recorded according to what Guo Tailai said, but there are obviously doubts.

Guo Tailai didn't explain this, nor did he intend to explain it at all. Anyway, some people in Mercedes-Benz know that they can achieve accurate values ​​without using those tools, and he has no obligation to explain to everyone who has doubts.

The comprehensive test of the engine on the test bench is to ensure that the engine is in good working condition and to obtain the most intuitive first-hand data. This belongs to Mercedes-Benz's internal quality inspection, and it will be submitted to McLaren after the quality inspection is passed. Then it's up to McLaren's technical director to decide whether to use this engine in F1.

The two engines started one by one, and just hearing the sound of the two engines, the experienced mechanics knew that they had lost.

The engine that Guo Tailai assembled has less vibration and a more balanced sound, which is even better than the one they assembled.

In the process of large-scale industrial manufacturing, there will always be a few workpieces with excellent processing precision, and there will always be a few assembly precision with very good precision. Those old technicians also have such a sound in their careers. I have heard it before, but it is only one of the tens of thousands of units that has such a performance. But Guo Tailai only assembled one, and they had such a sound, they felt ashamed.

If it is a different part, you can still look for the reason, but the same part is made by Guo Tailai, and it has been tested at the Mercedes-Benz headquarters and the industrial laboratory. With the same processing accuracy, if you look for the reason from the parts, it will not be possible. fit.

This group of veteran technicians simply surrendered without waiting for the test data to come out.

Fortunately, when the comprehensive data of the all-titanium alloy engine was higher than the data of some titanium alloy engines by nearly 5%, the smile on the face of McLaren's technical director could not be suppressed. This test data is about 7% higher than that used in their current car, and the weight is more than ten kilograms lighter. Even that part of the titanium alloy engine has two percent higher performance and lighter weight, because some parts are made of aluminum alloy, which has a lower density than titanium alloy.

At this time, the technical director regretted agreeing to the competition. Fortunately, there is still time for Guo Tailai to reassemble that part of the titanium alloy engine. As long as the performance of the other engine is comparable, these two engines are probably enough for all competitions this year. The strength of the titanium alloy engine is much stronger than that of cast iron and aluminum alloy.

However, this is only the prediction of the technical director. Whether it can be realized can only be supported after it is installed on the car and checked after each race to obtain detailed data. However, just a 7% increase in overall performance is enough for the technical director to wake up from sleep with a smile.

After the internal quality inspection, it must be packaged and transported to the team, which has nothing to do with Guo Tailai. According to the agreement between the two parties, after Guo Tailai disassembled the part of the titanium alloy engine and reinstalled it, the cooperation content has been completed. Mercedes-Benz paid very readily, and the vice president came forward to discuss further cooperation with Guo Tailai.

Before the negotiation, Guo Tailai had already called Sister Zhang and Lin Jiayi and asked them to come together to negotiate with Mercedes-Benz.

The content of the cooperation is limited to the all-titanium alloy engine. Guo Tailai operates by hand, and it is definitely meaningless to talk about mass production with him, but the more such handmade, it is the favorite of some nobles in the upper class. For example, Rolls-Royce is known as the best hand-made, and has won the favor of many nobles.

Guo Tailai's all-titanium alloy engine can completely cooperate with Mercedes-Benz to launch the top-end handcrafted limited edition of Mercedes-Benz's most high-end S series or off-road G series. I believe that once this gimmick is launched, it will definitely win a group of top customers.

What Guo Tailai wants to do is to build an all-titanium alloy engine. Guo Tailai has no objection to this, as long as the quantity is not too large, Guo Tailai can agree, and everyone just needs to negotiate the price. Lin Jiayi and Sister Zhang are responsible for solving price negotiations and legal issues.

Lin Jiayi had to hand over the construction of the company to Mi Feifei, and asked her to take over her job. She flew to Germany with Sister Zhang quickly and started negotiating with Mercedes-Benz.

After the engine was assembled, Guo Tailai also specifically asked Mercedes-Benz and McLaren whether they had a relationship with the Louvre in France so that he could get a close look at the real "Mona Lisa Smile". It's a pity that both sides shook their heads with regret. There are many friends in France, but none of them can satisfy Guo Tailai's request.

Such cooperation cannot be negotiated overnight. Last time Guo Tailai agreed very readily, but he also knew that he must have suffered a lot. Guo Tailai himself is not suitable for such a thing. He is not good at fighting for conditions bit by bit, negotiating bit by bit, so professional things should be handled by professional people, and he only needs to tell them the bottom line , and then let them go to negotiate, Guo Tailai just wait for the result by himself.

I thought that such negotiations would only last a few days at most, but unexpectedly, after a week, they still failed to reach a conclusion. The focus of the dispute between the two parties is that Mercedes-Benz hopes that Guo Tailai can only provide services to their family, but Guo Tailai is obviously not happy to do so.

"Mr. Guo, I think your characteristics are suitable for cooperation with some hand-built car manufacturers." Lin Jiayi was also annoyed by the restrictions on Mercedes-Benz, and after a week of not talking about it, she suggested to Guo Tailai: "Maybe we can contact Rolls-Royce , Koenigsegg, Pagani, etc., there is no need to be tied to Mercedes-Benz, Mr. Guo, what do you mean?"
