"It was given to me by my girlfriend, and I promised her that I would never leave her." Su Ming shook his head firmly, pressed the watch in his hand again, the guards next to him looked at each other, and said a lot in a very strong attitude, Watanabe relayed their meaning to Su Ming, saying that it was a matter of the company's top secret, and it must be strictly implemented in accordance with the regulations.

Su Ming also knows that concept cars or unlaunched models are the biggest secrets of automobile companies, once they are leaked, it means that the models that have been hard to drive for several years have been lost, generally speaking, those who can be invited to visit this are very distinguished guests, but Su Ming wants to take this opportunity to test his true attitude, and Ada said that he can't leave anything.

"Forget it, I've gained a lot from reading the front, and I'm very satisfied, so I won't look at the back." Su Ming turned to Watanabe and finished speaking, standing aside to see how they decided.

Watanabe discussed a few times with the vice president and the chief engineer, and then turned his head and said to Su Ming embarrassedly: "Mr. Su, this is embarrassing, it can't be accommodating, and the following visits are all at the same level of confidentiality, if Mr. Su's side can't be accommodating, then today's visit has to end here." ”

"That's the end of it, I just want to go back and rest for a while, and I'll be back in two days." Su Ming pretended to be indispensable, he didn't expect that there would be any big gains here, concept cars or something, what is the use of seeing it, and it can't be produced in China, and it is sold to other automobile companies, and Su Ming is not short of those two cents.

"Mr. Su's side really can't discuss anymore?" Watanabe felt very embarrassed, he had pulled people over from afar, and it was a little rude to go back like this, but the rules here were not something that could be changed at his level.

"I will never leave the table, there is absolutely no doubt about it." Su Ming's firm attitude made Watanabe very distressed, it's just a girlfriend, not a wife, and it's hard to say if you have a girlfriend or not, if you are really so loyal to your girlfriend, why do you want to get involved with our Sumitomo Flower.

"Mr. Su, you are our distinguished guest, wouldn't it be rude if it ended like this, can we each take a step and add a security measure to your watch?" Watanabe went back and discussed with the other side, and this time the guards also discussed, and several people argued very fiercely, shaking their heads and nodding their heads for a while, and finally came to a conclusion, Watanabe came over again.

"What security measures, you say?" Su Ming knew what the other party was thinking, but in fact, he had already given them a hint of never leaving his body, and it seemed that they finally understood.

"It's this black metal tape that wraps around your wrist." At this time, the security personnel had already brought the tape, and Watanabe took it and handed it to Su Ming.

Su Ming took the tape, which is a kind of tape with a metal layer shielding function, Su Ming took off the watch, first wrapped it with a handkerchief, and then wrapped it densely with several layers of tape, and then held it with his hand and asked the other party: "Is this okay?" ”

The other party wanted to take it and take a look, but Su Ming took it back and stared at him, the other party understood, so he lay on Su Ming's hand and looked at it, and didn't find that it was in a place that might be penetrated, so he was relieved, Su Ming threw the watch into his pocket, and Shi Shiran walked in.

Compared with the car outside, the car inside is really much more dreamy, especially a four-door bridge sports car, after getting used to the BMW M3, Su Ming likes this type of car very much, that is, it has strong and powerful power, and it can maintain a good comfortable surname, and the appearance is not so weird that people dare not go on the road.

"This is a model that we are preparing to launch in the next few years, and it has not yet been finalized and produced, Mr. Su came to see this model, I don't know if Mr. Su likes it?" The other asked, pointing to a royal blue streamlined car.

"This one is not bad, it looks like an RX-7, but it's a little different?" Su Ming looked at this car, which was similar to the RX-7 launched by Mazda, but the appearance was much weirder, especially the front face part, the lower half was a grille formed by the superposition of three Mazda logos, and the middle of the upper part was the Mazda logo, and the black on both sides was with silver stripes, which combined with the lower parts to form a huge Mazda logo, and the appearance was very conspicuous.

The RX-7 is different from the previous one, it is a pure bloodline sports car, this kind of car with a low center of gravity in order to ensure speed, there are few roads in China that can run, unless it is driven like a snail, it is better to drive an ordinary car.

"The RX-7 is the only sports car in the world with a rotary engine, and this is our limited edition model for special users, so customers of this car, no matter where you are in the world, can enjoy our Mazda 12-hour arrival and 24-hour solution." When he said this, the pride on the other party's face was fully revealed, but Su Ming was attracted by this rotary engine, isn't the engine an engine, what type of engine is the rotary engine, and it is the only one in the world? I missed a little for a while, and when I saw Su Ming like this, the other party smiled: "Mr. Su, if you have love for this car, go and pick your favorite color, and then do a surname test, and we will make you a car that is most suitable for you and give it to you, do you think it's okay?" ”

"Thank you, this car is really good, I like it very much." Like other people's products is to respect others, and I say that my cheap is not white, and it is also white, anyway, you don't want to get cheap with me.

"Thank you, thank you." Sure enough, Bai sent a car and the other party also expressed his gratitude to Su Ming, Su Ming didn't choose a color, he liked the color in front of him very much, and at the same time measured his height or something, and then the other party said that after three months, the car could be delivered to Su Ming.

Turned around and visited the production workshop again, this Su Ming was not interested, and the other party did not introduce much, but just looked at it in a fancy way, and came to a reading area, the door was still heavily guarded, and there were instruments to measure the body, Su Ming's watch was also taken out and checked once, and then he was allowed to enter this research institution.

When he entered the research institute, the first thing he introduced to Su Ming was Mazda's specialty, the rotary engine, Su Ming only then knew what this rotary engine meant, it turned out to be a triangular piston rotary engine, and reciprocating piston engines are commonly used in automobiles. There is also a well-known engine that is rarely used, that is, the rotary engine.

Due to the reciprocating engine, the piston does reciprocating linear motion in the cylinder during work, and in order to convert the linear motion of the piston into rotary motion, a crank connecting rod mechanism must be used, and a part of the efficiency must be lost in the conversion. Rotary engines, on the other hand, directly convert the combustion expansion force of combustible gas into driving torque. Compared with the reciprocating engine, the useless linear motion is canceled, so the rotary engine of the same power is smaller in size, lighter in weight, and has lower vibration and noise, and the disadvantage is that the fuel consumption is very large at low speed, which is an unacceptable factor in the world, and at the same time, because it can only be injected and not compressed, so diesel cannot be used.

This form of engine was invented by the German Wankel, but the rotary engine was developed in the hands of Mazda, especially in 91 at the 24 Hours of Le Mans in France, after Mazda's RX-7 won the championship in one fell swoop, the organizers of the race immediately announced that the next year's competition will prohibit other engines except for the duplex engine, and the power of the rotary engine can be seen.

In the sixties, Mazda obtained the patent and technology of this engine in the hands of Wankel, and has been focusing on the research and improvement of this engine for decades, and through 30 years of efforts, it has solved all kinds of problems of this engine.

When they led Su Ming to the front of the running engine, Su Ming suddenly paused, and then continued to observe very intently in the process of running the two engines, what is the difference, the shells of the two engines are transparent, it can be clearly seen that the rotary engine is indeed a lot less steps than the reciprocating engine, and the sound is small, the action is light, in terms of energy consumption and energy output, it is indeed not worse than the reciprocating engine.

For the shortcomings of this engine, the other party is also blunt, energy consumption can not continue to reduce, but the same energy consumption, the rotary engine can provide far more energy than the reciprocating engine, and the reciprocating engine, after more than 100 years of development, but there is no room for improvement.

At the same time, they led Su Ming to a room and introduced to Su Ming the most suitable energy material for the rotary engine, that is, hydrogen fuel, and there is a modified vehicle on the site, as long as there is a cubic meter of compressed hydrogen, it can provide hundreds of kilometers of energy, which is more than three times that of gasoline, and hydrogen combustion will produce a small amount of water, and there is no waste residue and waste gas and other pollutants, which is a clean energy material.

And the content of hydrogen in nature can be said to be endless compared to oil, water, air, land, including oil, all contain hydrogen, which can be said to be inexhaustible, Su Ming's eyes brightened when he saw this, and he said on the spot that he hoped to cooperate with Mazda in this regard.

Seeing this, Su Ming already felt very satisfied, and there was no need to look at the rest anymore, who could know how long the oil would last, who could master the new energy technology, and who would have mastered the future, and all of this was thanks to Ada.
