What's it called? Qin Yu was going to spoof him and call him a luxury car name such as Lamborgy Ferrari, and he wanted to call it a domestic brand such as Land Rover Chery Geely.

It's funny to think about.

But after thinking about it, this is the world's first car after all, and if it will be passed down to future generations, it is better not to use someone else's name.

So he put away his spoof thoughts and said, "It's called Dongfeng." ”

"Dongfeng Citroen!"

"Snowflake Goddess Dragon!"

"Dongfeng Iron Dragon!?" Zhu Yuanzhang's heart swelled with enthusiasm, "Good name!" It is a steel dragon from the eastern country, which will crush the worlds and overseas countries in the future. ”

It's actually a dragon!?

The villagers' expressions froze when they heard this, especially the old farmer who wanted Qin Yu to help pull the cow dung just now, and his heart trembled: I actually wanted the dragon to pull the dung for me just now?

Sin, sin!

We were riding a dragon just now? Han Yan'er, Lu Qingqian, Lingshu and other girls were excited when they heard this.

"Mr. Qin, what is it moving forward on?" Zhu Yuanzhang was like a studious student at this time, humbly asking Qin Yu for advice. I hope to learn the trick and then go back to the Ministry of Industry to imitate it.

"It's by the front of the car." Qin Yu said.

Pointing to the head of the car, he said: "The iron bump in the front of the car is the diesel engine, and its working principle is similar to that of a steam turbine." A diesel engine is a type of internal combustion engine. ”

"As for how to make it, I've already drawn the drawings."

"Got drawings?" Zhu Yuanzhang became excited, "That's great!" ”

It turned out that Qin Yu had already prepared everything for him.

Then he opened the lid of the front fuel tank, and the crowd saw that there was a pool of 'clear water' inside, and the smell was also very pungent, and the smell of diesel fuel was in the air.

"It turns out that Tielong's mind is full of water!?" The villagers were amazed.

"The power source of the diesel engine is diesel." Qin Yu said.

"Sir, you mean that this iron dragon drinks this kind of water as well?" The villagers were also very simple-minded, asking, "It takes two bowls of water to drive two kilometers." ”

And Zhu Yuanzhang was also curious to look at the diesel in the fuel tank, and it was estimated that it was not much different from what the villagers thought. Although he is much more awesome than the villagers, he is an ancient man after all.

Nor is there much more insight than theirs.

"It's all said, it's diesel, not water!" Qin Yu said.

"In other words, can't you fill it with ordinary water?" Zhu Yuanzhang said.

"Of course not, you have to use this oil to make the dragon move." Qin Yu said, "And it can't be mixed with water, once it is mixed with water, the machine will be wasted." ”

"But, sir, where did the diesel fuel you mentioned come from?" Zhu Yuanzhang asked another key question.

"Your question ......," Qin Yu said, "That's a good question." ”

"Diesel is purified from petroleum. Petroleum contains a variety of diesel, kerosene, engine oil, and polymer oil, each of which has a different boiling point, which can be extracted. Those polymer oils, although they are not needed now, will be used in the future, because they are all aviation liquid fuels. ”

"This belongs to chemistry, and I will teach my students next semester!"

"Sir, willing to pass on this knowledge to them!?" Zhu Yuanzhang became excited when he heard this. Being able to pass on advanced knowledge and not enjoy it alone is the greatest contribution to the Ming Dynasty.

It's really remarkable.

"Of course." Qin Yu said.

"I will definitely tell them to learn chemistry from my husband." Zhu Yuanzhang said, "Chemical knowledge can make this, it is really immortal knowledge!" ”

"By the way, do you know what oil is?" Qin Yu asked Zhu Yuanzhang.

"I don't know." Zhu Yuanzhang shook his head.

"It shouldn't be." Qin Yu said, "There is a record in "Mengxi Writings on Oil": There is oil in the territory of Yan and Yan, and it is said that it is "Gaonu County Fat Water...... Try to sweep its coal as ink, and the black light is like lacquer...... This thing will become more popular in the world in the future......"

"Look, Shen Kuo has already predicted, this thing will definitely be of great use in the future."

"Mengxi Pen Tan was written by Shen Kuo from the Song Dynasty, you shouldn't know it."

"It's because our knowledge is not good, so Mr. smiled." Zhu Yuanzhang said embarrassedly. Emperor Zhu had no money to study when he was young, and although he later learned a lot of knowledge from Confucianism, he learned some Confucian knowledge and Tao Te Ching, and "Mengxi Writings" belonged to the side of the study, and was looked down upon by those Confucians.

Mengxi Pen Talk is regarded by them as a strange skill, that is to say, it is estimated that even Liu Bowen and Song Lian have not read "Dream Creek Pen Talk", let alone Zhu Yuanzhang.

Don't think that the ancients knew everything about ancient knowledge.

"I didn't expect that "Dream Creek Writings", this little-known book of strange skills and obscenity, contains such clever knowledge!!" Zhu Yuanzhang said.

"Yes, it's not that we don't have good things, but our good things are suppressed and can't develop. Before it developed, it was strangled in the cradle. Qin Yu said.

"Sir, according to the records in "Mengxi Writings", in the territory of my Ming Dynasty, Yanzhou and Yanzhou are rich in oil, and then the oil can be processed to refine diesel kerosene?" Zhu Yuanzhang asked,

"Yes." Qin Yu said, "I also have the relationship of classmate Huang Fan, so I helped me get a barrel of oil in these two places, and then processed and purified the diesel." ”

"In addition, some kerosene was extracted, and now I use kerosene lamps at home."

"It turns out that the family uses kerosene lamps!" Princess Ningyang seemed to remember something, and said in a fuss, "I was surprised when I saw the kerosene lamp a few days ago, how can water burn?" ”

"My house is full of high-tech!"

"I'll give some to the villagers when I get back." Qin Yu said.

"Great!" The villagers were thrilled to hear this, and from now on they could use high-tech kerosene lamps. admires Qin Yu's character even more:

Whatever Mr. Qin invents, he shares with everyone, not one person monopolizes it.

"Since there is oil in Yanzhou and Yanzhou, it would be great!" Zhu Yuanzhang said, "Yanzhou and Yanzhou are in Shaanxi for a generation, and it seems that Shaanxi, a poor province, will prosper again because of this." ”

"It's like the coal mines in Shanxi."

"If there were large-scale manufacturing of motor vehicles in ancient times, the demand for oil would definitely be very large, and the oil abundant in the two places of Yanzhou and Yanzhou may be a little insufficient." Qin Yu kindly reminded.

"yes, so what to do?" Zhu Yuanzhang also came back to his senses and asked. If you want to make this kind of Dongfeng Iron Dragon in the whole country of Daming, the oil produced in the two places of Yanzhou and Yanzhou will definitely not be enough.

Because these two states are so small.
