Lin Yuan continued: "This technique is exhaust gas turbocharging, a necessary technique for every traverser!" ”

Sun Yunchao couldn't help laughing when he heard Lin Yuan's words, he said: "Exhaust gas turbocharging: use the exhaust gas after doing work to push the turbine, and the rotating turbine increases the air pressure entering the combustion chamber, which not only increases the power that the engine can provide, but also greatly saves fuel consumption, which is indeed a good idea, but the difficulty of this kind of thing is not small, and it is not something we can play now." ”

Sun Yunchao explained: "The air pressure entering the combustion chamber increases, the heat generated by combustion will also increase, and the heat load of each component of the combustion chamber will also increase. ”

"If we design the boost ratio to be relatively large, with our existing materials, the piston top of the cylinder will not be able to withstand that high temperature at all, and the service life will be greatly reduced, so the turbo increase is not for anyone to use, at least we can't use it now."

Lin Yuan nodded and said, "Okay then, let's not use turbocharging." After we designed the diesel engine, we used it to replace the boilers and transmission parts on the existing anti-smuggling vessels. Wan Ling couldn't help but laugh when he heard this, Lin Yuan knew that he must have made some mistake again, and laughed at the generous family, so Lin Yuan asked a little embarrassedly: "Wan Lao, what are you laughing at?" ”

Wan Ling said: "Do you think the power system can be changed if you want to?" The diesel engine has the best working speed point, the continuous power is the largest when working at this speed, and the propeller also has the best working speed point, and the propulsion efficiency is the largest at this speed. ”

"Also, when the ship is in the water, the center of gravity and the equivalent center of all buoyancy do not coincide, so when designing, we should try to control the weight distribution, so that the two points are too far apart, if the difference is too far, there is a vernacular, the ship will sink at one end, and it will tilt an angle as soon as it enters the water, which has a great impact on the subsequent use of the ship, so the equipment on board cannot be changed randomly."

"When our new type of marine gas turbine came out, some people in our country said that our new gas turbine should be replaced with those old warships as soon as possible, and I also wrote an article in a military magazine to explain the difficulty of this matter, and the supporting transmission system and propeller had to be greatly changed, so it was not so easy to change the engine."

Lin Yuan nodded and asked, "Then what do you say we should do?" Wan Ling said: "We started from scratch and built a new type of maritime patrol ship. ”

Lin Yuan asked, "But is it too late?" ”

Wan Ling said: "The manufacture of the hull is not difficult, because this type of ship is relatively small, so relying on the craftsmen of the Jilin Machinery Bureau, we can manufacture it, just wait for the power system to be installed, and it can be used after testing." ”

Lin Yuan asked, "Okay, I'll wait for your news." ”

Lin Yuan returned to the Governor's Yamen from the arsenal, and when Chen Qingyun saw Lin Yuan coming back, he hurriedly stepped forward and said, "Lin Shuai, you can be regarded as back, I have two important things to report to you." ”

Lin Yuan replied, "Don't be in a hurry, speak slowly." Chen Qingyun said: "The first thing is: five new smoke houses have recently opened in the city. ”

Lin Yuan nodded and asked, "What about the next one?" ”

Chen Qingyun said: "Lin Shuai, can't you let the smoke house go on, this opium is a disaster for the country and the people!" ”

Lin Yuan said confidently: "Don't worry, I know the opium thing." ”

Chen Qingyun said: "The second thing is that the British factories have already started working, but they are discarding the discarded stones at will, which makes the people in the vicinity complain. ”

Lin Yuan thought to himself: "The stone left after the bauxite production of alumina is a good thing to make concrete, and it must not be wasted." So Lin Yuan ordered: "You immediately send someone to collect their discarded stones, and then build a warehouse nearby, and hoard these stones, I will keep them for important use." ”

Chen Qingyun nodded and said, "What about opium? ”

Lin Yuan smiled: "You don't have to worry about opium, I have my own way." ”

Half a month has passed in a blink of an eye, the time has entered April, the weather has gradually warmed up, Lin Yuan received news from the arsenal: a new type of maritime patrol ship has been built and transported to Yingkou Port.

Lin Yuan immediately rushed to Yingkou Port after receiving the news, when he arrived, Wan Ling and Sun Yunchao were trying to test the new boat at the anti-private water training ground, they were traveling on the water, and the shore was full of anti-private sailors watching the excitement, but Lin Yuan did not see the battalion commander Gu Jinkai, so he asked a sailor: "Where is your battalion commander?" ”

The sailor said: "I was called over by the director of the tax department, Asko, and scolded, that foreign devil, when he saw the fire, he took us out of anger, it's not a thing." ”

It is not surprising that after the Second Opium War, Britain forced the Qing government to sign the "Sino-British Trade Charter", Article 10 of which clearly stipulates: let the prime minister invite the British (American, French) to help with taxation, and strictly investigate tax evasion......

Because the British are the most powerful, so in 1859, the British Li Tai was appointed as the "China General Taxation Department", until 1863, the British Hurd succeeded to the post of General Taxation Department, Hurd during his tenure, in more than 30 treaty ports have established tax departments, Yingkou Port is also among them. Lin Yuan inquired about the location of the tax department, so he walked over quickly, and when he arrived, he was stopped by the British guards at the door, Lin Yuan casually said a few words of English to frighten the guards, and Lin Yuan immediately walked into the tax department.

As soon as Lin Yuan went up to the second floor, he heard a person's roar in the corridor, in blunt Chinese, so Lin Yuan understood as soon as he heard it: it must be the director of the tax department who is scolding Gu Jinkai.

Lin Yuan was just about to listen attentively, when he saw a door open on the side, Gu Jinkai walked out of it indignantly, and when he saw Lin Yuan, he asked in surprise, "Lin Shuai, why are you here?" ”

Lin Yuan smiled: "I'm here to find out the quality of this director, what's wrong with you?" Did something go wrong? Gu Jinkai sighed and said: "Today they said that they received a report that two British ships were smuggling sweaters, and let us go to investigate, but the British ships are too fast, and we can't catch up at all!" Its ship was still out of range of our machine guns, and I had to come back and report that it had not caught up. ”

"Who knew that this director of the department didn't ask about it, and he scolded me for half an hour when he opened his mouth! If I am at a loss, this anti-smuggling ship was given by the British, and now their ship can't catch up with others, he actually scolded me for not having the ability, you say that this matter is not angry! ”

Lin Yuan smiled and said: "You don't have to worry, I'm here to send you a new ship, this ship is guaranteed to be able to catch up with any enemy ship!" ”

Gu Jinkai's eyes lit up when he heard this, and he followed Lin Yuan to the water training ground, and when he saw the boat, he couldn't help but pout his mouth high, and said in disappointment: "Even this boat can be used!" ”
