When everything was taken care of, Lin Yuan returned to Mukden, he was afraid that Shen Wanqing would blame himself like in Vladivostok, so he didn't tell him his true whereabouts, only said that he had inspected the troops, and Shen Wanqing didn't ask in detail, and when Lin Yuan was left alone, he thought back to the Japanese ship, and the more he thought about it, the more strange he felt. Two days later, Lin Yuan asked people to send him the photos taken during the surveillance, and when he saw the photos, Lin Yuan suddenly realized, picked up the photos and came to the arsenal.

After Lin Yuan entered, he found a room at random, only to see that the people inside were busy drawing design drawings, the ground was full of eraser scraps and pencil scraps, and a few T-rulers were placed in the corner messily, Lin Yuan went in and asked, "Are the experts there?" ”

The people inside were all young engineers on the Beijing ship, and they all knew Lin Yuan, so they all stood up and said hello, Lin Yuan walked among the crowd with a smile, and said jokingly: "Why are you so messy here?" ”

A young girl blushed and went to get a broom by the wall, and said embarrassedly: "Today is my duty, and I was busy checking the strength, so I forgot." ”

Lin Yuan then asked, "Is the mechanical expert Yan Siming Yan here?" ”

The girl said, "Teacher Yan went to the expert meeting, and it was in the conference room of the arsenal. ”

Lin Yuan asked, "Expert meeting?" What is that? The girl smiled: "It is experts in various fields, and they will talk about the progress in their fields at the meeting to see if others can use it, and we will have such a meeting here once a week." ”

Lin Yuan nodded, came out of the room, came to the conference room, gently pushed the door open and entered, only to see Yan Siming dancing on the stage and talking: "Our high-precision gear technology has made a new breakthrough, Lao Liao, if you want to build a gas turbine engine, you don't have to worry about the fuel pump without gears." ”

In an aviation gas turbine engine, the supply of oil to the combustion chamber requires a large amount of pressure, which is provided by a pump composed of gears, and the gear set is connected to the main shaft of the engine through a series of structures, which is driven by the main shaft to rotate.

Lin Yuan's opening made everyone turn around, and when they saw Lin Yuan, they all laughed and said, "Why is Comrade Xiaolin here?" Is there something wrong? ”

Lin Yuan shook his head again and again and said, "You guys talk about it first." ”

Yan Siming smiled: "We've finished talking, you should talk about your business." ”

Lin Yuan then walked up to the stage, turned on the projector, and then put the photo under the projector, a clear image of the photo suddenly appeared on the big screen, Lin Yuan pointed to the photo and said: "This is the new type of high-speed boat I found by the Japanese, they use this kind of boat to transport drugs to our country, I first saw it and felt a little strange, I don't know if you see anything strange?" ”

Ship expert Wan Ling only glanced at it and said, "The chimney of this ship is too small, it's just like nothing!" ”

Lin Yuan thought to himself: "An expert is worthy of being an expert, and it only took a glance to see what I had been pondering for a few days." Lin Yuan smiled and said, "Wan Lao is really good eyesight, but can you tell me why the chimney of this ship is so small?" ”

Wan Ling frowned, thought for a while, and said, "Is it the angle of the photo?" ”

Lin Yuan said with a smile: "In my opinion, it was the Japanese who installed a new type of power system on the ship, and I suspect that this power system is the internal combustion engine!" "All the people present are engineering experts, engineering can be divided into two categories, one is mechanical, the other is power electronics, mechanical experts have more or less heard of the internal combustion engine, but the power electronics class is different, they hear the term "internal combustion engine" are at a loss.

Liao Ming, an aero engine expert, said with a smile: "The internal combustion engine, as the name suggests, is that the combustion and work of the fuel are carried out inside the machine, as opposed to the external combustion engine, such as the steam engine that is most widely used in various countries in the late Qing Dynasty. ”

"According to the movement form of the work parts, the internal combustion engine can be divided into reciprocating and rotating, the rotary type is our gas turbine, such as aero engine, reciprocating is like a car, the gasoline engine and diesel engine commonly used in tanks, which are used on ships, military ships generally use gas turbines, and civilian ships mostly use diesel engines."

When Liao Ming said this, everyone looked at Sun Yunchao, an expert in diesel engines and gasoline engines, who is also an academician of the Chinese Academy of Engineering, and participated in the design of the power system of the third and fourth generation of main battle tanks.

Sun Yunchao said: "In modern times, most civilian ships use diesel engines as power, but the first diesel engine was used as ship power in 1904, and the prototype of the diesel engine appeared in 1898, so I think the Japanese ship is likely to be powered by a gasoline engine." ”

"Compared with the original steam engine, the diesel engine and gasoline engine will have an advantage in small ships because of their light weight, so the speed of this ship will not be slow." Lin Yuan said: "That's right, this is also the purpose of my visit this time, the Japanese ship is very fast, and our anti-smuggling ships are all eliminated by foreign devils, when I rescued Chinese laborers, I couldn't catch up with the American devil's ship, and now it is even more impossible to catch up with the Japanese ship, so we must use the latest power!" That's the diesel engine! Sun Yunchao smiled: "Great, we are finally going to build a diesel engine, with a diesel engine, we can build tanks and high-power trucks." ”

Lin Yuan said with a smile: "You are right, the diesel engine is simply a catalyst for industrial development, you can think like this, with the diesel engine, we have an advanced power source, in this way, we can manufacture a large number of agricultural machinery, just as we are reclaiming the Great Northern Wilderness, with advanced agricultural machinery, I believe we will soon be able to solve the food problem!" ”

"With diesel engines, we can also build a lot of construction machinery, such as multi-bucket excavators, cone rock drills, concrete mixers, etc., these construction machinery can reduce our construction of hydropower stations, the time of the dock is doubled, and when the power station dock is completed, it is the era when we dominate the world!"

Everyone smiled when they heard this, and then metallurgical expert Liu Jinqiu said: "But we can't make a lot of materials now!" What we lack most now is a variety of element ores, the characteristics of alloy steel are like this, sometimes there is a lack of a certain element, and the performance is not good! ”

Sun Yunchao said with a smile: "It doesn't matter, we can build a simple diesel engine, and the parts in it are all made of our current materials, I don't think there is a problem, and when we open a scale to mine all kinds of ores again, we will re-produce a batch of high-quality ones." ”

Lin Yuan said: "I know that there are many ores in the northeast, so we must transfer them from all over the country, but the transportation is really underdeveloped, and when our various transportation facilities are complete, we can transfer them from all over the country." ”

Sun Yunchao said with a smile: "We have been preparing for the manufacture of internal combustion engines for a long time, you can rest assured, if all parts fully cooperate, we only need about ten days to make the first batch of internal combustion engines." ”

Lin Yuan said with a smile: "We not only have to build a diesel engine, but also apply the same necessary skills for every traverser on it." ”
