Chapter 452 Install PK (Part 1)

To be honest, the workers in the industrial laboratory were also taken aback. The processing precision of each of the titanium alloy parts brought over today is extremely high. According to their measurements, they have all reached the level of 0.1 micron. Even the highest precision CNC machining center does not seem to have this precision, right?

Guo Tailai seemed very satisfied with the machining accuracy, at least whether it was Huang Weiguo and the staff of Mercedes-Benz, they could see Guo Tailai's satisfied smile.

Two days later, the group drove back to the Mercedes-Benz headquarters in Stuttgart again. Next, Guo Tailai will assemble the two engine parts.

McLaren insisted that Guo Tailai install the two engines with bare hands, but Mercedes had a different opinion. Although they have all seen the stability and accuracy of Guo Tailai's free-hand installation and the improvement of engine performance, Mercedes-Benz still wants to assemble one of the engines.

After the two parties negotiated, they negotiated with Guo Tailai again. Guo Tailai has no objection to this. Why not do it if he can assemble one less engine and still charge the same fee? However, Guo Tailai insisted that this all-titanium engine was installed by Guo Tailai himself, and Mercedes-Benz can install another one.

The installation was carried out in another assembly workshop, and a Mercedes-Benz assembly team composed of senior technicians, holding various tools, was ready to do so. On the other side, on another assembly table not far from the same assembly workshop, there was only Guo Tailai alone. All kinds of tools were also available, and the three of Huang Weiguo were there, but the three of them just stood by, faithfully performing their duties as bodyguards, and had no intention of interfering at all. There are two engineers on each side who record the relevant processes, and they will check off each completed item to ensure that no operation is missed.

Except for the different materials in some areas, the thickness of some parts, and the overall weight, the principles and designs of the two engines are exactly the same. Theoretically, the output power and output torque of the two engines should be the same, so the assembly of these two engines has become an unofficial little competition between the Mercedes-Benz senior technician team and Guo Tailai's assembly skills.

On one side is a senior technician carefully selected by the German nation, and on the other side is a young man from China who is said to be a master, and the operation is still purely manual. It’s okay if the machining accuracy of the fully automatic CNC machining center is not comparable. If it is even inferior to the senior technician team in assembly, then Mercedes-Benz needs to study carefully to see whether Mercedes-Benz has been striving for excellence over the years.

There is no comparison in terms of processing. Mercedes-Benz has completely admitted that its skills are inferior to those of titanium alloys, which are difficult to process metals. Therefore, in terms of assembly, you must win back, and you must win beauty. The vice president in charge of production personally mobilized them before the war, and in any case had to overwhelm Guo Tailai in order to seize some opportunities in the subsequent negotiations.

For this reason, the senior technicians selected this time are the most experienced veteran technicians stationed at the headquarters who do not know that the performance of the engine installed by Guo Tailai has been improved. They will not be affected by Guo Tailai's previous record.

Mercedes-Benz has the pride of Mercedes-Benz, and they don't seem to want to take advantage of the time. When Guo Tailai picked up the tools and started to work, the other side took action. On the assembly table, a group of people began to get busy.

Various connecting rods, cams, valves, etc. began to be assembled carefully. Guo Tailai looked relaxed, and the Mercedes-Benz team was not nervous. Everyone acted in an orderly manner, and no one affected the other.

It's just that when they started to move some heavy parts, the two sides saw the gap.

For Guo Tailai, everything is basically assembled by hand. The entire engine was designed according to the design, and the combined weight of all the workpieces did not exceed one hundred kilograms, which was not a problem at all for Guo Tailai's abnormal physique at the moment. Therefore, for the final cylinder part, Guo Tailai also installed it with both hands, without using lifting equipment.

Not so with the Mercedes-Benz team. Even for the accuracy of the assembly, they have to use lifting equipment to help with the suspension, and only need to adjust the angle manually.

In this way, for fear that the lifting tool may slightly hit the workpiece, even when the suspension is suspended, the team members are careful to protect it, and the natural progress will be affected. In terms of speed, how efficient the previous people were Guo Tailai's lead was evened up a little bit by Guo Tailai.

Guo Tailai's assembly is already incomprehensible. For the V-shaped cylinder, Guo Tailai stretches out his hand to grab the piston and inserts it. He is not afraid that a slight deviation in the angle will lead to unsmooth installation and increased friction during later work. It stands to reason that this method of not measuring at all and relying on the feel of the eyes should be completely abandoned and replaced by high-precision mechanization. However, when Guo Tailai installed it, it was so easy, and there was no wrong angle at all that could not be inserted. The situation is simply unbelievable.

Especially when Guo Tailai held the upper part of the cylinder with both hands and lowered the cover, the Mercedes-Benz team was still cautious even if they used lifting equipment. Even more adjustments. But where is Guo Tailai? He put it on so easily, isn't he afraid of being wrong?

Although everyone couldn't believe it at all, Guo Tailai had already started to screw the nuts over there. Seeing the ease with which the screws are inserted in, it shows that the up and down alignment is still very precise. However, it is obvious that Guo Tailai held the installation with both hands, how could it be possible with the strength of human arms?

Obviously, in the later stage of assembly, the installation of the Mercedes-Benz team has been disturbed by Guo Tailai's actions alone. No matter what Guo Tailai was doing or what process he was doing, those senior technicians would always take a look here. All kinds of doubts, shocks and disbelief made the installation efficiency of the Mercedes-Benz team several times lower.

The final result was that when Guo Tailai had finished installing the 85kg all-titanium alloy engine by himself, the part of the titanium alloy engine installed by ten people from the Mercedes-Benz team was still a few steps away from the final steps.

Although the time difference is not even ten minutes, the senior technicians of the Mercedes-Benz team have completely lowered their proud heads. Ten people working together are ten minutes later than one person. No matter how the assembly quality is, the assembly efficiency will lose first.

Next, without dismantling each other's engines, the two sides appreciated each other's installed engines. At this stage, neither Guo Tailai nor the Mercedes-Benz installation team made any comments on the engine installed by the other party.

Afterwards, the two engines were filled with lubricating oil, added coolant, powered on, and carried out a comprehensive inspection after starting on the test bench.
