Open an aircraft carrier to fight against Japan

Case said confidently: "Is there anything I don't understand." As he spoke, Case walked to the diesel engine, pointed to a large can next to it and said, "This is gasoline."

Case pointed to the pipe connecting the tank and the diesel engine and said: "This is the oil pipeline. Gasoline flows into the carburetor of the gasoline engine through the oil pipeline. The function of the carburetor is to break the gasoline into tiny particles. The air being sucked in mixes, which is the intake stroke of the four strokes, and then the piston compresses the mixture, which is the compression stroke."

"After the air and gasoline are compressed to a certain extent, there will be an ignition device to ignite. At this time, the gasoline will expand and burn, and the high-temperature and high-pressure gas generated by the combustion will push the piston to do work, that is, the power stroke, and then the exhaust gas will be discharged. Go, that's the exhaust stroke, that's how a gasoline engine works."

Lin Yuan applauded lightly after hearing this, and said with a smile, "Wonderful! Very exciting!"

Nuoer said angrily: "Don't think that we will let you go if you say a few nice words."

Lin Yuan ignored the angry Noel, but called a mechanic nearby and ordered, "Go and get some of the oil we used."

The mechanic nodded and went out, and came back soon, holding a cup in his hand, and then put the cup on the ground, Lin Yuan pointed to the diesel inside and asked Case: "The gasoline you are talking about, is it this kind of thing? "

Case poked his head out to take a look, and saw that the oil looked very dark, not as clear as gasoline at all, and said, "Strange, is this the oil you use? It is impossible to use this kind of oil. In a gasoline engine."

Lin Yuan pointed to these oils and said: "These oils are all low-quality oils left after petroleum distillation. In your country, these oils are only used to produce chemical products, but when they come to me, they are the most precious fuels."

In the diesel engine used in ships, in order to reduce the operating cost, the diesel engine will choose low-quality oil when designing, and the price of these oils is very low, but the combustion chamber and oil supply system must be specially designed to use this oil, that is these The Germans could understand, Lin Yuan took out a match from his pocket, ignited it, and then made a gesture to throw the burning match into the oil.

Case turned pale with fright at Lin Yuan's actions, and said, "What are you going to do? It will explode, and we will all die."

But it was too late for Keith to stop it, the burning match had already fallen into the oil, only heard a sound of "呱啦", the match emitted a puff of white smoke, and then went out, Lin Yuan smiled and said: "This Are you sure we're not using gasoline?"

Case nodded, and Lin Yuan said again: "In order to convince you, I will ask someone to remove the cover of the cylinder, so that you can take a good look at our principle."

As soon as Lin Yuan waved his hand, a mechanic came forward. Generally, gasoline engines or diesel engines share one cylinder head with multiple cylinders, but each cylinder of this type of diesel engine has a cylinder head. The mechanic stepped forward, Unscrew the connecting thread on the cylinder head, and then remove the cylinder head.

Case stepped forward immediately, and Lin Yuan said to him: "As you said, gasoline must be ignited to burn after entering the cylinder. Look, can you find something to ignite?"

In a gasoline engine, the ignition tool is called a spark plug. Case has seen many spark plugs. He is confident that he can pick out the spark plugs among many parts, but when he saw the components inside the cylinder, he was surprised to find that he could not find them at all Not the spark plug, not only that, he has never seen the internal components of the cylinder.

Case panicked a little, and he couldn't help thinking: "Did the Chinese really develop an internal combustion engine that can be used without spark plugs?"

Just as cold sweat was dripping from Case's forehead, Lin Yuan smiled and said, "Is it a bit of a surprise? I can tell you that the principle of our engine is completely different from your gasoline engine!"

Noel didn't know much about technology. He looked at Case, and Case said, "The technology they use is really not ours, and they may use more advanced technology. I can't understand it at all."

Lin Yuan asked with a smile: "Would you like to listen to the principle of our engine?"

Without waiting for Noel to speak, Case said anxiously: "Of course, tell me the principle quickly."

Lin Yuan squatted down, picked up the cup of oil from the ground, and said, "The key lies in this cup of oil. This oil has a wonderful property. When the pressure is high, it can burn itself without igniting a fire." Combustion, so we use a compression ignition engine."

When Case heard this, he couldn't help but said, "Have you ever cooperated with Diesel?"

Diesel is the father of the diesel engine. The compression ignition principle of the diesel engine was first proposed by him. The diesel engine does not need an ignition system. Compared with the gasoline engine, it has great advantages, so that in modern internal combustion engine applications, except Small cars are still using gasoline engines, and other fields, such as military vehicles and construction machinery, are dominated by diesel engines.

Diesel proposed the principle of the diesel engine in 1892, but it took until 1898 to actually manufacture the diesel engine. Of course, Lin Yuan had heard of Diesel's name, but he did not admit it, but laughed: "Diesel Who is it? Does he also understand compression-ignition diesel engines? If he understands this kind of thing, others must understand it too."

Case stopped talking, because they were convinced that they lost this matter, and Noel said helplessly: "Let's go, we lost this matter!"

Noel took Case and the reporters out of the door. Lin Yuan was about to say some sarcastic remarks in the back to get angry with these arrogant Germans. At this moment, a message from Shen Wanqing suddenly came from the communicator: Come back quickly, we're in big trouble.

Seeing the news, Lin Yuan didn't dare to neglect, he hurriedly got out of the boat and went back to his residence, thinking that Shen Wanqing was already in the house, he opened the door and went in, but there was no sign of him, just when Lin Yuan was wondering, She saw Shen Wanqing walking in from the outside holding a stack of documents, her forehead was covered with sweat.

Lin Yuan let her into the room, poured her a glass of water, and said, "What's wrong with you? You're so tired that you seem to have run for five kilometers."

Shen Wanqing raised her head and drank all the water from the glass of water. Without even wiping the water from the corner of her mouth, she handed a stack of documents in front of Lin Yuan, and said, "I made a special trip to Fengtian to collect all these things. I brought it here. You guessed it right. The British aluminum factory has indeed signed a lot of orders, and these orders will be delivered in a few months. I took a quick look and found that the amount of aluminum needed is very large. Finish."

Lin Yuan took those orders and looked at them page by page, only to find that this batch of aluminum involved nearly ten companies, including Mercedes-Benz in Germany. Because aluminum alloy has a low density, it is relatively light under the same volume. A material that the industry loves to use.

Another company is the Edison Electric Company. Because the mechanical properties of aluminum alloys are better than copper alloys, aluminum alloys are usually used in long-distance power transmission. Lin Yuan looked at the amount of the order below and thought: "It's okay, it doesn't count. It's too big, and the total amount is less than forty tons." Lin Yuan turned to the last page while thinking this way, and he couldn't help but be surprised by the content on it.
