In less than half a month, the first 'carriage' equipped with an internal combustion engine appeared, with the experience of the steam engine, and the crankshaft connecting rods were readily available, but the craftsmanship on the ship was transferred to the carriage.

Daniel immediately sent the sample to Mavi and talked about the new 'carriage'.

"Teacher, you see, we installed the factory crankshaft on the car to ensure that the power of the internal combustion engine can be transmitted to the four wheels one to one."

"Is it okay to run?"

"It's been tested! It's fast! ”

"Daddy, I want to sit on it!"

Yunia is very interested in the new means of transportation, and immediately wants to take a test ride, Ma Wei did not stop her, she is a god, even if the car is smashed, she will not be injured at all, not to mention that the test drive is in the suburban grass, and there is no need to worry about who will be pressed.

Daniel acted as the driver and stood in the back of the carriage, Otto and Barnett put the burnt red copper wire into the combustion chamber with their hands and feet, Daniel pulled the lever with his right hand, and the kerosene began to burn, and the car shook and rumbled.

Sitting in the car, Yunia said 'wow', leaning on the window to look, Otto and Barnet carefully checked the condition of the car after starting, and after confirming that there was no problem, they made an OK gesture to Daniel, Daniel pulled the left lever, the crankshaft began to rotate, and the car quickly rushed forward!

According to Mavey's eyesight, the car was moving at the same speed as an adult man running at full strength, slower than a horse-drawn cart, but much faster than a steam car.

The concept of automobiles was actually born as early as the age of steam, and the so-called "steam" does not refer to gasoline, but to steam.

Looking at the speeding car, Yunia let out a cry of delight, and Daniel kept changing directions, turning the car around, always at the same speed, as if there was no way to speed up or slow down.

Just when Daniel was excited, he only heard a clang, and the sound of some kind of steel collision sounded from under the car, and then the car seemed to be equipped with a spring, and the tail was bumped, and the unsuspecting Daniel flew directly into the air, smashing his head on the grass, and the car that lost control was like a wild horse that had escaped from the reins, rushing straight into the woods.

The crash was not heard, and within a few minutes, Yunia came out of the woods with her car.

The wheels had stopped spinning, but the internal combustion engine was still working, and Barnett and Otto hurried up to check it, only to find that the connecting rod was broken.

The crankshaft connecting rod is machine-tested and used by steamships, so it stands to reason that there will be no problems, but the key is that the car has to steer, and the speed of the front and rear wheels is inconsistent when steering, which will cause the connecting rod to rub and twist, and eventually break.

Daniel clutched his sprained neck and got up from the grass, limped back, and after understanding the root cause of the problem, he fell into deep thought.

"Why don't you use the wheel behind you to generate a forward force and the wheel in front to steer?"

Edward said: "Isn't it okay to divide the front and rear wheels separately? ”

"The internal combustion engine is mounted at the bottom of the cabin, and if it only produces power to the rear wheels, it will cause a warping phenomenon."

"Then put the internal combustion engine in the front of the car to balance the weight!" Levin didn't understand what Barnett was struggling with, and this kind of thing came to mind with his brain!

With the help of the team, the solution was quickly found, Barnet and Otto immediately went back to remake it, Daniel chased after him despite the pain in his neck, Levine and Edward also had high hopes for the new tool, and Yunia looked at their departing backs with some hesitation.

"Aren't you going?" Mavi asked.

"Dad, are you going?"

"I have something to do in the afternoon, and the church is waiting for me to deal with it."

Ma Wei shook his head slowly, he was not very interested in the history of the development of automobiles, not to mention that he was entangled in official business, and it was already good to be able to spare time.

"Go if you want, Otto, they are all top scientists, and you will definitely learn from them."

Practice is the best teacher, just like the lessons of the past, you can't remember it after listening to it a hundred times, but you will never forget it after experiencing it once.

Yunia doesn't want to sit in the classroom and teach obediently, so find her a practical teacher, and she can also learn things.

"Then I'll go, Dad, see you in the evening!"

"See you in the evening."

Yunia trotted after her, following Daniel and the others back to the windmill workshop and starting to redesign.

The car itself was not damaged, except for the broken connecting rod, and Barnet and Otto removed the internal combustion engine, removed the power lever that connected the front wheels, and connected only the lever that controlled the direction

The exterior of the car had to be redesigned to challenge the direction of the internal combustion engine, but in the case of simple experiments, there was no need for an outer shell, not even a seat, and a control seat was sufficient.

At sunset, when the sky was dark, a modified car was once again ready, without a cabin, without glass, with the internal combustion engine and various connecting rods completely exposed.

This time the internal combustion engine was placed in the front position, Daniel stood above the rear wheels, nodded to Barnet and Otto, started the car, and with a rumbling sound, the car began to move forward, straight ahead, no problem, but when Daniel made a turn

Syllable!

The right front wheel detached directly, and the car fell to one side, stuck on the grass and could not move.

Everyone hurriedly gathered around, and Barnett frowned: "How can this be, shouldn't it?"

The detachment of the wheels means that the car has encountered a great obstacle, and the terrible thing is that they can't even find the problem!

Yunia stared at the broken axle for a long time, and seemed to understand something.

She turned her body in place and looked down at her feet: "When we turn to the same side, the force on both feet is different!" Will the same be true when the car turns? ”

"Ackerman turns!" Otto patted his head and completely forgot Yunia's identity: "You mentioned the method of turning the carriage proposed by George, the engineer of the Kingdom of Frederick in 1817!" This carriage uses the same principle, and it stands to reason that the same problem will not occur."

"The problem is not in the front wheels, but in the rear wheels."

Edward said suddenly: "The carriage is pulled by horses, the power comes from the outside, and the car is rear-wheel driven, when we only use the front wheels for steering, the rear wheels will exert a forward force on the front wheels, if the speed is too fast, there will be a rollover, the speed is too slow, and the wooden wheels will also twist and break because they can't withstand the stress generated by the steering."

"What about iron tires?"

"The connecting rod that was broken just now is the best answer, and if you don't solve the problem of the direction of the force, the car can't turn perfectly."

Four-wheel drive steering, will lead to connecting rod breakage, front-wheel drive, there will also be axle fracture problems, as Edward said, the key to the car turning problem is not the front wheel, but the rear wheel!

While everyone was thinking about a solution, Daniel suggested a different way of thinking: "Why do you have to be a four-wheeler?" Since steering is difficult, why not just use two wheels? ”

"Two wheels?" Barnett looked up: "Is it like a two-wheeled carriage?" ”

"Not one left and one right, but one front and one back."

Daniel made a cart motion: "Haven't you seen a wheelbarrow?" People push behind and apply power forward, just like a car! ”

One before and one after.

"Isn't that going to be out of balance?" Barnett looked puzzled: "The triangle is the most stable, maybe we should make a tricycle!" ”

"Tricycles aren't going to have steering problems yet!" Otto said.

"Separate the two wheels! There is no link in between, so there are no steering problems! ”

Otto shook his head, not disapproving of Barnett's idea, but wanting to solve the problem, not run away.

Maybe Barnett's idea works, but who will solve the problem of steering on four wheels?

Do things carefully and meticulously!

However, Barnett believes that it is necessary to seize the trend of the internal combustion engine and promote it vigorously, not just four-wheeled vehicles.

The two disagreed, and eventually broke up, Daniel was for Barnett, but he didn't want to give up the four-wheeled car either, and everyone knew that four-wheeled cars were more likely.

At Daniel's recommendation, Otto went to the Royal Academy of Sciences in London to seek help from more scientists, while Barnet continued his research with his team, and just when Mavi thought the matter was over, Katerina found him.

"Father, I heard that Barnet developed the internal combustion engine?"

In the evening, Katerina invited Mavi to dinner, and the dim candlelight at the quiet table looked a little beautiful.

"Your Majesty's news is really well-informed."

"I want a prototype." Katerina said bluntly: "Eggs can't be put in one basket, maybe the Royal Academy of Sciences in Mosk can study something different." ”

"The machine is already on its way." Ma Wei said lightly: "The technology sharing of the Northern Alliance is not a lie. ”

"Arthur, does he agree?"

"He's not very happy, but he doesn't have a problem either."

Hearing this, Katerina picked up her wine glass, took a sip and said: "Priest, maybe you feel that you are favoring the Romanov Kingdom, maybe it is true, but please believe in the potential of the Romanov Kingdom, and please also tell Arthur that one day, the Romanov Kingdom will be stronger than the Windsor Kingdom!" At that time, we will also come up with the most advanced technology and share it with them! ”

The investment may not have a return, but if there is a guarantor and this guarantor is reliable enough, the stability of the investment will definitely be greatly increased.

The Church of Truth is the link between the countries of the Northern Alliance, and without Ma Wei in the middle, no one will trust anyone, let alone give their most precious technology to others, who will test each other's humanity with the interests of the moment?

Because of the Church of Truth, because of Mavi, the Northern Alliance was formed, Arthur didn't believe in Katerina, and Katerina didn't believe in Arthur, but they both trusted Mavi, so they signed a contract.

Katerina's words were addressed not only to Arthur, but also to Mavey, and were more like a fear of being abandoned by the Church of Truth than a declaration.

"The Romanov Kingdom helped us in the most difficult period for the Truth Church, and this is also the place where the Truth Church has flourished, of course I believe in the potential of the Romanov Kingdom, Your Majesty, you don't have to test anything, as long as the Romanov Kingdom still trusts us, the Truth Church will not abandon the Romanov Kingdom."

Katerina smiled slightly, and said with a bow, "No one believes in you more than I do, Father Priest, and from the first moment we met, I saw the trajectory of the future. ”

Putting down her glass, Katerina changed the subject: "Next week I will take an airship to London to lead the Olympic team and try out with the Olympians from the Kingdom of Windsor." ”

"Your Majesty, are you here in person?"

"I value this opportunity, and I want to visit the Kingdom of Windsor in the open." Katerina's eyes drifted and her tone was very light: "At that time, I hope that the priest can organize a banquet to introduce me to the celebrities of the Windsor Kingdom." ”

"No problem."

Ma Wei agreed, as Katerina, not to mention celebrities, even Arthur can see him if he wants to, isn't it easy to organize a banquet?

Those celebrities can't wait to see her!

Downstairs, Ma Wei's carriage left, and the personal maid Marusa brought decanting soup to Katerina, and saw Katerina standing in front of the window in a daze, and asked curiously, "Your Majesty, what are you thinking?" ”

"I'm thinking about next week's banquet."

"What's there to think about at the banquet?" Marusa was puzzled: "You have attended as many banquets as you have eaten!" ”

"I'm thinking about what to wear."

"You have a lot of clothes, not to mention that you are so beautiful, you look good in anything." Marusa said with a smile.

Katerina said to herself, "I heard that she likes to wear red, and this color is very eye-catching. Well, just wear that blue dress. ”

"Also, inform Bodlinov that he will come with me to London next week."

"Yes!"

The next day, the internal combustion engine from London arrived in Mosk, and Katerina personally received it, and after watching the launch demonstration, she asked Pugachev, the president of the Academy of Sciences, next to her: "How soon can you reproduce it?" ”

"Half a month!"

"I'll give you three days." Katerina said coldly: "In three days, I must see the car with the internal combustion engine. ”

"Three days?!"

Pugachev said hurriedly: "Your Majesty, it is not difficult to reproduce the internal combustion engine, but it is not easy to make a car!" At the end of the day, the internal combustion engine only changed the way the power is delivered, not the fundamental problem! ”

"The internal combustion engine changes the future, we are already one step behind, we can't continue to lag behind, no matter what method you use, you have to give me an answer in three days, I not only want you to reproduce the internal combustion engine, but also want you to be ahead of the Windsor Kingdom!"

Pugachev gritted his teeth and could only bite the bullet, Katerina did not give him any room for mediation.

Returning to the Royal Academy of Sciences, Pugachev immediately summoned all the researchers, professors, and asked them to disassemble the internal combustion engine, draw drawings, study the principles of operation, and improve on them.

"Three days! We only have three days! Your Majesty wants to see the results! ”

Pugachev shouted with red eyes: "In three days, if you can't do it, everyone will be finished together!" ”
