Chapter 175: Titanium engine (top)


The glass windows in the workshop are large, and many people outside can see the work inside. In the eyes of these British and Germans, this primitive technique of hand-polished is too old, too primitive and too inaccurate, and it is completely out of the development of the times. can
Yes, the piston that I just took out was obviously polished out with this simplest manual method, but the light is the mirror finish of the surface, I know that this is definitely a rare boutique. The two surveyors were poisonous in their eyes, and similar workpieces could not be seen in tens of thousands of pieces. After reading it with experience, it is measured with the instrument, and the unprecedented precision is even higher than that made by the Mercedes-Benz high-precision machining center. Look
With such a result, the person who has just been questioned has been completely transformed from questioning into worship. There are several old people in the team that watched, and it is also a relief. They were also hand-polished experts, and they were slowly replaced by machines. Guo Tailai's hand is equivalent to saving the honor of manual processing for them. more
The scary thing is that they didn't see Guo Tailai using a measurement tool from start to finish. It is said that some masters know the size as long as they touch it. Some young people always think that this is a legend of exaggeration. Now, seeing Guo Tailai’s undisguised performance, they are not allowed to believe it. It turns out that there is such a legendary master in this world!
All of this happened under the eyes of everyone. Guo Tailai is not likely to cheat. People from McLaren and Mercedes will not allow Guo Tai to cheat. Until now, McLaren’s talents really realized how the prototype of Guo Tailai came from, and believed that Guo Tailai’s hand-processed titanium alloy was seen by Songshan Jiuzhi.
When Guo Tailai was busy for half a morning, when he came out from the dust-free workshop to prepare for lunch, a group of McLaren and Mercedes-Benz technicians who had been waiting at the door stood spontaneously on both sides of the door, with reverence in their eyes. Guo Tailai applauded enthusiastically. Guo
It took only half a morning for Tailai to conquer the more than a dozen staff members present, and there was no doubt that he had half a word on his handwork. On the contrary, everyone has a little more expectation. What kind of wonderful performance will the engine with such precision make?
On the 3.0v10 engine, Guo Tailai completed almost six pistons in the morning. In the afternoon, all the pistons were taken out with other small parts. After dinner, Guo Tailai did not rest, but continued to work. The crankshaft camshafts were completed one after another. After only the cylinder is left, this will stop. Hugh
The interest was also overnight, and the next morning, Guo Tailai built the largest and most complicated cylinder. Although all the parts were polished from rough-worked parts, Guo Tailai's efficient processing speed scared the technicians of the two companies.
The next step is naturally assembly. In cooperation with Longfei, several Mercedes-Benz technicians attacked, and Guo Tailai still assembled the entire engine with the most primitive manual method. The total weight of this engine is only less than one hundred kilograms. Guo Tailai can actually get it alone.
The assembled engine was connected to the test bench and the circuit was connected to the oil circuit to start the test. More than a dozen engineers were busy, and one after another data was quickly released, forming a complete report. The next morning, it was placed in front of the McLaren team manager and technical director. "
The maximum power output has only increased by four percent. The maximum torque is not much changed, but the life expectancy is increased by 20%. The technical director was shaking with the data and looking at the body: "Is it really effective?"


It’s just the data on the test bench.
The team manager was relatively able to hold his breath:
You have to get on the train for one or two stops to see the real results.


I was thinking, if I really replaced the cast iron parts with titanium.
The technical manager looked at the data and said,
What kind of improvement would there be?

The technical director has not been idle for a few days. When Guo Tai came to work, he had taken a group of engineers to calculate the possible performance changes after replacing the titanium alloy. hair
The weight of the motive can definitely be reduced, but the strength of the same volume of titanium alloy is definitely higher than that of cast iron, and it can last longer. Or, regardless of the life, and continue to maintain the existing strength, the weight can be further reduced. However, for the sake of life, some aluminum alloy parts are also replaced with titanium alloys, and the life will be greatly improved without reducing the weight.
The calculation is the impact of these different directions. Engineers should use previous experience to judge and estimate, and form quantitative indicators, which are handed over to the team manager and technical director for judgment. Of course, the processing cost of different choices is also different, and it needs to be listed at the same time as a cost item for reference by the superior.
McLaren’s team experience and technical director are making decisions, and Mercedes-Benz is also making choices. Unlike McLaren's own accounting costs, Mercedes-Benz is more direct. According to McLaren's thinking, if some limited-model engines are replaced with high-precision ferroalloys, will there be local buyers? Ben
Certain high-end models of Chichi can directly consider the all-titanium engine, giving customers a unique sense of dignity. Of course, the price will be extremely impressive. This alone will make the difference between the two cars with the same engine material and the difference of one million dollars or more. Performance will definitely change, but customers will not accept this is the point. Want to know this, it is estimated that some surveys should be done among high-end customers.
But before that, whether it is Mercedes or McLaren, it is necessary to come up with a solid engine to prove that the titanium engine is different. Otherwise, the empty mouth speaks vernacular, and the engineers understand that there will be performance differences, but it does not mean that every customer knows.
"If you need to verify the advantages of titanium engines." Mercedes-Benz is also very concerned about the reputation of the engine manufacturer in the f1 competition, so after knowing that McLaren has been somewhat tempted but blocked by high costs, Proactively found the McLaren team: "Mercedes can be responsible for 50% of the cost, but the experimental data must be shared with Mercedes."
People are willing to pay half of the cost, what else can the McLaren team consider? In particular, Mercedes-Benz is still the engine provider of these two years, and they have contracts with them. Of course, there is no problem with data sharing.

Processing costs two million dollars? Processing two sets of four million?
Guo Tailai heard the request made by McLaren, did not ponder how long, still decided to take the order. Because Guo Tailai himself wants to verify the performance of the titanium engine, is there a better place to test the strength and weakness than in the f1 stadium?
