Americans are a country that advocates individual freedom, they feel that the reason why rich people are rich is because of their ability, no one accuses him of why he doesn't help the poor, thinking that this is a moral kidnapping, but this does not mean that Americans do not respect those who are good at helping others, a caring person will be respected by others in any country, coupled with Liu Lang's clever tongue, he cited Fleming's example, which immediately raised his character to the height of world celebrities, and even Hanks was infected by his personality charm。

Although Hanks had never heard of this legend..........

Well, this story was read by Liu Lang from a book in China, and he thought that this Fleming was very noble, but is history really like this? Liu Lang didn't know, this story is just a "chicken soup" story similar to Newton being hit on the head by an apple and discovering gravity.

But this is not the point, the point is that Liu Lang refused the patent transfer fee of 650,000 US dollars, and gave the right to use this kind of ladder to the other party free of charge.

"Jimmy, on behalf of Director Howard of the California Emergency Management Agency, I would like to pay you my highest respect!"

Banksy and Makda stood up and saluted Liu Lang solemnly.

"You're welcome, let's go through the relevant procedures now!"

"Yes, yes, hurry up and go through the formalities!"

Banksy urged Makeda to say that it was useless to say anything until the relevant agreement was formally signed.

Makda is a legal adviser, and the purpose of his visit is to prepare Liu Lang to raise the price, but on the contrary, Liu Lang did not want a penny and gave his patent to the Emergency Management Bureau for free.

This kind of agreement is very simple, Makda drew up an agreement, Liu Lang signed this agreement, he also wanted to draw a charge, but was stopped by the other party, the Americans do not pay attention to this ..........

"Chief Banksy, you firefighters are a group of people worthy of respect, I hope the ladder I designed can help you save more people, and I would like to express my highest respect to all firefighters!"

The reason why Liu Lang gave this patent to the other party is not that he has too much money, but that he really thinks that they are a group of people worthy of respect, when the fire broke out, they were the first to rush to the fire to rescue the trapped people, this courage is not ordinary people can have, in the 911 incident 14 years later, nearly 1,000 firefighters sacrificed their lives in order to save other lives.

Not only the Americans, but also those soldiers in China are even more so, usually they seem to feel that no one is allowed to enter, but when disaster strikes, these people will definitely come forward, the flood in 98 is the embodiment of this spirit, I don't know how many soldiers died in the flood in order to rescue ordinary people, Liu Lang's contribution to these people is really insignificant in front of them.

Liu Lang's move was willing, Banks felt that this child deserved his respect, especially the identity of the other party made him feel very rare, Liu Lang is a Chinese child, and learned from Professor Hanks that he is not Chinese, a native Chinese.

What is the spirit of a Chinese who came to the United States thousands of miles away, without self-interest, exclusively for the benefit of others, and contributed to the fire cause of the United States. This is the spirit of internationalism, this is the spirit of communism. A person has great or small abilities, but as long as he has this spirit, he is a noble person, a pure person, a moral person, a person who is free from low-level tastes, and a person who is beneficial to the people..........

Well, Banksy is not good enough to express Liu Lang's internationalist spirit in words, but he can grasp the basic meaning and show deep respect for this spirit.

Liu Lang, Professor Hanks, Director Banks and Mark Da stood together and took a group photo, and Liu Lang and Director Banks signed the contract and left a photo at that time.

It's noon when I've done this, and I didn't have any classes in the morning, but no one in the university cares if you go to class or not, and Liu Lang's classes are full of randomness, and sometimes you even see him in Arabic language classes.

Professor Claire was nowhere to be seen, and Liu Lang ran to the library to read a book after lunch, and it was not until two o'clock in the afternoon that he found him in Professor Claire's office.

"Professor, this is the information you gave me, and I will give it back to you!"

"Oh, I gave you two months, and it's only been a little over a month now, why can't you understand?"

"No, I already think I see it all!"

Liu Lang smiled.

"See it all?"

Professor Claire was a little surprised.

"You can test me!"

Liu Lang said confidently.

"Okay, then I'll test you now!"

"Let me ask you first, how are the engine piston rings installed?"

"Well, there are generally 3 piston rings, 2 air rings and 1 oil ring from top to bottom. There are direction marks on each ring, and the side with direction marks is facing the top direction of the piston, and the assembly points are: the wrong position of the piston ring is the key factor that determines the sealing effect of the piston ring, and the opening of the first air ring should be towards the side of the cylinder wall with less lateral pressure, which can slow down the wear. If it is an integral oil ring, the opening of the three piston rings should be staggered by 120o; if the oil ring is composed of two oil scrapers, then the two air rings are staggered by 180 o, the two oil scrapers of the combined oil ring are staggered by 180 degrees, and the upper oil scraper of the second air ring and the combined oil ring are staggered by 90 degrees. ”

Liu Lang replied directly.

Professor Claire's question is definitely not the original question on these materials, for example, this question is just an article about various problems in the piston ring of the engine, this question is contained in it, but it is only slightly mentioned, and it is not fully expanded to explain, Liu Lang can answer so completely because he has completely understood these questions and does not let go of any place that he does not understand.

Professor Claire glanced at Liu Lang and showed a look of surprise, what is the matter with this little guy? Could he really be able to fully understand the more than ten papers and lesson plans? He thinks that even a student who has just become a doctor cannot do this.

"Well said, it seems that you really have a heart, but ......... I ask you, how is the piston assembled into the cylinder block?"

"Well, take the 4-cylinder engine as an example, the order of the piston connecting rod assembled into the cylinder is 1 cylinder, 4 cylinder, 2 cylinder, 3 cylinder, rotate the crankshaft, so that the connecting rod journal of the 1 cylinder and 4 cylinder is at the lowest point position, and the special tool is set on the outer circle of the piston ring, so that the piston ring is compressed to be flush with the outer circle of the piston, and the big end of the connecting rod is extended into the cylinder.

It should be noted here that in the process of loading, the big end of the connecting rod should be supported by hand to avoid the connecting rod bolt from scratching the cylinder wall and crankshaft, and the top of the piston should be pressed against the non-metallic rod to push it into the cylinder. After all piston connecting rod groups are installed, rotate the crankshaft to see if there is any difficulty in rotation or loosening, and if there is a need to find out the cause......... ”

Liu Lang replied immediately.

Professor Claire squinted, Liu Lang's answer was almost perfect, and he definitely couldn't answer this level if he didn't completely understand the knowledge points.
