At the end of April, the internal combustion engine was put into prototype testing. When Song Yang came back, the prototype testing had already failed twice.
As the saying goes, failure is the mother of success.
The R&D team did not give up because of the failure. After finding the reasons, they made adjustments and continued the process of prototype testing.
June 20th, the third prototype test started today.
Song Yang was invited to the scene to observe.
He was not there the first two times. People in the R&D team said that it failed twice in a row because the prince was not here and Luck was not here either.
This time they said they would wait until Song Yang came back before testing, saying they wanted to borrow Song Yang's luck.
Song Yang went to the test site with a smile early in the morning. Wang Jinshi and two Mohist apprentices had already installed the No. 3 prototype and were debugging the external support structure.
"Your Majesty, you are here."
"Yeah. You guys are busy, I'm just here to take a look."
Song Yang watched them working, and the alarm clock pulled out some introductions and drawings of internal combustion engines.
In appearance, the No. 3 internal combustion engine is very similar to the engine of the Sanbengzi.
"Your Majesty, the adjustment is complete." Wang Hun straightened up and said.
He and Xu Ling are the persons in charge of mechanical design, and they were responsible for the design and assembly of Unit 3.
"Okay, let's get started." Song Yang nodded.
He also has high expectations for the No. 3 engine, which looks very similar to a modern three-bounce engine.
"Why don't you, Your Majesty, start it?" Xu Ling looked at Song Yang.
They all want to borrow some of Song Yang's luck...
After two failures in a row, the R&D team was somewhat confused.
"Okay. Here comes the king!"
Song Yang walked to the front of the No. 3 engine and saw a crankshaft inserted inside.
Song Yang held the crankshaft and started shaking it.
Song Yang has actually done this before.
He was only a teenager at that time, and there were such hand-cranked engines in the countryside.
Song Yang gradually found the hand pole from back then.
Unit 3 also reacted to the shaking.
"chug!"
"Tu tu tu tu!"
"sudden!"
"Chug, tug, tug, tug, tug!"
Seeing that the internal combustion engine was about to start running, Song Yang showed a look of joy on his face.
The people in the R&D team also grinned.
It seems that borrowing Song Yang's luck is indeed the right decision!
"Tu tu tu tu!"
"Bang~biu~puff~touch!"
Song Yang was still happy, so he worked harder.
As a result, Unit 3 made a strange sound.
After that, some black smoke came out from a certain location.
Finally, everyone's expressions turned stiff.
Song Yang's luck...is useless!
Unit 3 failed again.
And facts have proven that success or failure has nothing to do with Song Yang.
"Haha! It's okay! It's all a minor problem! Let's continue working hard on research and development!" Song Yang smiled to ease the awkward atmosphere.
"Yes! It must be a small problem! It has nothing to do with the prince's luck!" said the upright Xu Ling.
Song Yang: "..."
In short, Engine No. 3 failed again, and the road to research and development of internal combustion engines was indeed long and difficult.
Several people dismantled the internal combustion engine step by step, and finally discovered some problems.
It's due to rough processing and some flaws in the design.
Wang Hun immediately made a rectification plan, recorded the plan in a book, and started over again when he returned.
Experiments are just like that, always moving forward through failure again and again.
Song Yang didn't urge anything, he just encouraged everyone to move forward.
Back in the office, Song Yang started thinking about it on his chair.
There was still no movement from the internal combustion engine, and he was considering whether to jump onto the generator.
Steam power machinery has been relatively complete, and the equipment used to produce generators is not a big problem.
If we could build a generator, we might be able to use electricity to drive machinery, internal combustion engines, etc., very quickly.
In addition, if electricity is available, electric welding will be available. With electric welding, the ocean shipping industry will be able to improve rapidly.
Song Yang closed his eyes and looked up the introduction to generators in the encyclopedia.
There are indeed many types.
Nowadays, there are two types that are closer to reality: wind power and hydraulic power.
The difficulty lies in the copper wire.
It is not impossible to use a steam engine to draw copper wire, but the processing precision may not be ideal.
However, as long as one generator can be produced, the rest can be gradually replaced by electricity.
Thinking of this, Song Yang opened his eyes and decided to move towards the electric age immediately.
Arriving at the workshop area, Wang Jinshi's team was busy working on the internal combustion engine.
Song Yang then asked Liu Bao to come over.
This guy has also escaped from the youthful youth, and last year he married a daughter-in-law who is a female worker in a textile factory.
In the past two years, he has been working as the director of a firearms factory, producing a large number of muskets for Jiangzhou's Northern Expedition.
He is the most outstanding among the rear personnel.
"Electricity? What is that?" Song Yang shared his thoughts with Liu Bao.
Liu Bao was a little confused.
Song Yang explained electricity and Liu Bao again.
"A power source that is more convenient and efficient than steam?" Liu Bao's eyes lit up.
Although steam engines are very advanced, boring gun barrels still takes a long time.
Moreover, the neat power is not particularly smooth, and the inner wall of the barrel is often uneven, requiring workers to polish it manually.
According to Song Yang, electric machinery has higher efficiency and better smoothness. Liu Bao feels that this thing can completely improve the quality of muskets.
"You can understand it that way. And electricity can not only be used for power, but also for lighting. The effect is ten times better than candles!"
Song Yang kept telling Liu Bao about the benefits of electricity, which made him want to get electricity now.
"This thing also needs research and development, it doesn't mean it can be built just because it is made. Electricity is more difficult to make than steam, and a lot of things need to be prepared in the early stage." Song Yang said while holding down Liu Bao who was eager to try.
"Your Majesty! Just tell me what to do!"
Liu Bao looked at Song Yang and said firmly that he had made up his mind to create electricity.
"We have to make three machines first. To make a generator, we cannot do without copper wire. To make copper wire, we need a wire drawing machine."
Song Yang took Liu Bao to the desk, spread out a palm of papyrus, and Song Yang took a pen to write and draw on it.
Soon, models of three machines appeared, and Song Yang wrote the three characters "wire drawing machine" next to them.
"Copper wire? Can't it be made directly or poured?" Liu Bao asked with some confusion.
Song Yang shook his head and said: "No! The efficiency is low, and the thickness is uneven. The cast one is too thick. We need to make the copper wire the same as sewing thread!"
"Sewing thread!" Liu Bao was a little shocked. Can copper wire be made so thin?
In order to make useful copper wire, Song Yang transferred Wang Muyue over.
This boy has become a master of the blacksmith class, and his craftsmanship is not much worse than his father's.
His brother and his father are both studying internal combustion engines, and his second uncle is in charge of the blacksmith workshop.
Song Yang asked him to work with Liu Bao.
"Wire drawing machine? This... is not difficult."
Having built a steam engine was enough to give him confidence. Song Yang explained the wire drawing machine to Wang Muyue, and Wang Muyue said he could do it.
"Okay. Then start work as soon as possible and make three sets. The groove wire holes should be of three sizes from large to small."
Song Yang wants to build a large, medium and small Sanzhong wire drawing machine. There are three processes. What should be the use of the copper wire produced?
"Your Majesty, the mechanical problem is not big, but you said you want pure copper, which is not easy. Most of the copper in our city is alloy copper." Wang Muyue said about copper.
For production needs, Jiangzhou's copper is almost all alloy copper.
Pure copper can only be found in Daye, and it must be mined in Songtian and directly refined into pure copper.
"I told Song Tian about this, you need to get the machinery out first." Song Yang nodded.
"Don't worry, Your Majesty, this machine is not difficult. Our city now has a complete supply of materials. We can make one within half a month." Wang Muyue assured, patting her chest.
During the war in the previous two years, Jiangzhou accumulated a large amount of steel building materials.
Now that the fighting has stopped temporarily, there is a pile of materials left.
Song Yang planned to vigorously develop the shipbuilding industry, but the new shipyard was still under construction and the old shipyard did not consume much energy, so these materials were piled in the warehouse.
"Don't be impatient, make the machine more detailed!" Song Yang said, posing on Wang Muyue's shoulders.
"Yes! I understand, little one!"
After arranging the copper wire matter, Song Yang drew a few parts drawings for Wang Muyue.
There are shells, rotors, etc., these are all easy to make. Wang Muyue directly handed them over to his apprentice, while he concentrated on the research and development of the wire drawing machine.
After that, I discussed with Liu Bao the working principle of the generator and the use of electricity.
Song Yang first thought of electric lights.
Tungsten is produced in Jiangzhou. Tungsten ore was discovered before. Song Yang had people store a small amount of it in order to one day make tungsten filament lamps.
With tungsten filament material, it is possible to make light bulbs.
Song Yang found Gongsun Mo and left the matter of burning paper lampshades to him.
Liu Bao came to develop tungsten wire.
Then Song Yang thought about the need to flush nitrogen into the tungsten filament bulb.
According to Encyclopedia, nitrogen can be produced by heating a mixture of saturated ammonium chloride solution and sodium nitrite crystals or saturated solution.
When making soda ash, both substances were produced, and these were recorded in the chemistry laboratory.
In this way, the nitrogen problem is solved.
Speaking of the chemistry laboratory, it was set up by Song Yang a few years ago. It is located in the school and is managed by the chemistry teacher.
The so-called chemistry teachers are actually students of Song Yang.
The dean of education is none other than Chu Zian, who has the most outstanding reputation among the first batch of graduates.
During the war, the boy also worked part-time in the security team for a while.
Under his leadership, the chemistry laboratory has produced many new substances.
For example: ammonium chloride, sodium nitrite.
There are also elements such as oxygen, silicon, aluminum, iron, calcium, sodium, potassium, magnesium and hydrogen.
It can be said that Chu Zian has surpassed the teacher Song Yang in terms of chemical attainments and operational abilities.
In order to create nitrogen, Song Yang found Chu Zian again, gave him the reaction formula, and let him solve the rest by himself.
Chu Zian got the new reaction formula and left happily, saying that the results would be available soon.
That was really fast. Chu Zian came back with a glass bottle of nitrogen in the afternoon.
"Is this nitrogen?"
"Yes! Your Majesty, there is indeed nitrogen here!"
"how to prove?"
"Well... the one prepared according to the formula you gave... should be nitrogen..."
