When the researchers at the shipyard heard that Xia Li was going to modify the car's engine, no one had a bad attitude towards her.

After all, there is no competition of interests between the two parties, one is a shipbuilder, the other is a car, even if they are both improved engines, there are still some differences.

The little old man led by Lu Dingyuan heard Lu Dingyuan's request, and directly beckoned to the old man standing by the window watching others draw drawings, "Old Wu! This little comrade wants to know what materials we have now, you tell her! ”

After finishing speaking, he turned his head to look at Xia Li, and said with a smile: "If you have anything you want to ask, you can ask Lao Wu, Lao Wu is a professional materials scientist and knows the existing materials very well." ”

Xia Li is not a person who doesn't know what to do, everyone is so polite, and she also replied with a very good attitude: "Then trouble Wu Gong." ”

Wu Gong is also a little old man, although he looks a little thin, but he is a smiling face, with a thick-soled big round glasses, and walks over happily.

"You're welcome, they are all contributing to the motherland, how can there be so much to say?

Little girl, see what kind of material you want, and I'll introduce you. ”

Lu Dingyuan saw that Xia Li could handle this matter, and the attitude of the people was very good to her, so that she would not be in a situation of violence and hurt, so he said to her: "Dabi is a little busy, I'll go back to work first."

Let Zhao Qiang come over to help you in a while, and you can ask him for whatever you need. ”

Lu Dingyuan didn't think that he would be able to pick people up after a trip, but he just wanted to make an appointment with Xia Li, and then he would arrange it.

But I didn't expect to pick people back directly, and I also rubbed a meal.

As the battalion commander of the independent regiment, the two armies are very comparative, and there are many things in the battalion that need to be arranged by him, so naturally he has no time to follow Xia Li all the time.

After confirming that there are no "risk factors", he offers to leave.

Xia Li came over this time to be responsible for his quick mouth, so naturally he wouldn't look at Lu Dingyuan.

immediately waved his hand at him, "It's okay, you go and get busy, I'll let Zhao Qiang send it to you after I finish drawing the picture here." ”

Lu Dingyuan nodded, then turned to leave.

Xia Li carefully inquired about what kind of materials are available today and what the properties of the materials are.

The little old man surnamed Wu originally thought that Xia Li was just a junior, but listening to her questions, listening to it, his eyes gradually became serious.

There's something about this little comrade!

There are a lot of material development directions, all of which they have never thought of before.

If it can really be developed according to her requirements, it will definitely be a great progress in materials science!

Raised his hand and waved to the few people sitting around the wall, "Lao Zhang, Lao Xu, this little comrade is very thoughtful in material science, you can also come and listen!" ”

Called Lao Zhang, Lao Xu's two little old men are also good-natured people, and when they heard Lao Wu call them like this, they immediately surrounded them happily.

After a while, the three little old men of materials science all gathered around Xia Li and followed her to discuss the future development direction of materials science.

Xia Li: ......

Is it possible that I'm here to ask questions and not to be asked by you?

These three serious-faced head teachers surrounded the immediate sense of the errand students, what was going on?

Xia Li took a lot of effort again and again to bring the topic farther and farther back to the question she wanted to ask.

I finally coaxed everyone away, and then I had time to start drawing the engine.

As a result, as she painted, she found that there were more and more people around to watch her draw designs.

Xia Li: ......

Suddenly, there was a premonition that the scene that was about to become an airplane and was surrounded by scientific researchers to ask questions was repeated again.

Sure enough, at the beginning of the answer to Lu Dingyuan, the little old man who was the leader of this group of people lifted his glasses, frowned at Xia Li's drawings, and suddenly asked out loud: "Little comrade, do you want the fuel to be premixed with fuel and air before it reaches the cylinder?"

It's a novel concept. ”

Xia Li: ......

Xia Li said in his heart, sure enough.

As soon as she was dragged by the old man to ask questions, she knew that she would start drawing designs in a while, and it would most likely turn into another defense.

After leaving the university for a long time, I once again ushered in the graduation defense surrounded by several professors.

Is it really...... It's hard to put into words.

But when people asked, she didn't want to herself, so she replied casually, "Yes."

Simply burning gasoline is not very efficient, and it can even be said that the efficiency is very low.

Between 14% and 30% of the potential chemical energy in gasoline is converted into the energy that actually drives the car. The rest is lost due to idling, parasitic losses, heat and friction.

In older engines, fuel was injected directly into the cylinders, which was a huge waste of resources.

Whereas, turbochargers use exhaust gases to power the turbine, injecting additional exhaust gases into the cylinders for further propulsion.

It can improve efficiency by up to 8%. ”

The expressions on the faces of the people present, especially the scientists who studied the engine, suddenly became solemn.

There are a total of 14 points, and an increase of 8 points is already more than half of the increase, and it is not as easy as this little comrade said.

This is a big step forward for science!

Everyone immediately began to discuss this issue, not only discussing it themselves, but also pulling Xia Li, who was dedicated to painting, to discuss it together.

Although the engines of cars and battleships are not the same, some things are still universal, and the principles that can be applied to car engines can also be referred to on their warships.

The discussion was in full swing, and the eyes that looked at Xia Li were shining, and even a few little old men secretly wanted to pull Xia Li into the gang during the discussion.

It doesn't matter if you're not engaged in battleships, you can learn slowly! There is no end to learning, I didn't see that Lu Xun originally studied medicine, and later didn't he rely on the pen to fight the world and save the country and the people?

There are more and more people here, and the discussion is getting louder and louder.

In the midst of the voices of the old men, a young voice suddenly came, "You want to apply this to the actual car engine?"

Whimsical, there is no way to apply it at all. ”

The sound of the discussion stopped instantly, and everyone's eyes looked at the person who spoke.

When I recognized who this person was, I was a little unsure of the truth of what he said.
