Chapter 229 (Large Chapter) Heavy Oil Steam Engine Pickup

In fact, this vernier caliper does not require any refined scales at all. Only a small change can complete the upgrade of the accuracy to 0.1 or even 0.02 scales.

Many people who have used a vernier caliper know that the scale on the lower vernier is not set according to one centimeter or two centimeters.

There are several different cases, there are ten racks of 9 mm and fifty racks of 49 mm.

This kind of thing is something that only some junior high school physics course teaches for a few minutes, and most people forget about it after listening to it. Huo Hai also forgot about it, but he saw it again when he watched a short video later.

When I was in junior high school, I didn’t understand anything and just listened blindly.

As an adult, I watched the short video and then understood the principle, and I was amazed.

The principle is very simple. In theory, a vernier caliper only needs one mark. This mark is aligned with the ruler above, and the reading is what it is aligned with.

For example, if something is stuck, the cursor mark below is aligned to 1.2 cm, and the natural reading is 1.2 cm.

But with ten grids, there are only nine millimeters of markings in total, so the method of reading has changed.

The zero mark is at a certain distance on the ruler, and the reading above millimeters is this.

For example, align the space behind the 10 cm 3 mm scale and the space between 10 cm 4 mm.

So, the first half of the reading is 10 centimeters and 3 millimeters. So how much is the extra bit after the millimeter?

The answer is simple. The nine-millimeter cursor below has a total of ten grids, and only one of the lines can be aligned with one of the lines above.

What does alignment mean?
For example, the first line is aligned with the grid above.

What does it mean?
This means that the extra point out of 10 centimeters and 3 millimeters, plus the 0.9 millimeters of the first grid of the cursor below, is exactly 10 centimeters and 4 millimeters.

Doing subtraction, ten centimeters and four millimeters minus 0.9 millimeters, we get ten centimeters and three point one millimeters.

Doesn't that mean that the distance between the calipers and the object is 13.1?

And larger readings, and so on.

The design of this cursor is very simple, and the reading rules are actually very simple as well, but it still took Lanshe some time to make the people on site understand how to use this thing.

To put it simply, the first mark on the vernier is 0.1 millimeter away from the one-millimeter position on the upper ruler.

The second marking line is 2 mm above the ruler, with a difference of 0.2 mm.

The third line is off by 0.3 millimeters, the fourth line is off by 0.4 millimeters, and the ninth line is off by 0.9 millimeters.

The difference can be calculated by which marking line is aligned with the scale mark above. The difference plus the previous reading of the ruler that is aligned with the zero scale line is the object's spacing reading of 0.1 mm accuracy.

A ruler with fifty graduations totaling forty-nine millimeters can measure tiny distances with an accuracy of 0.02 based on the same principle.

After Tian Yi understood, he was amazed: "It turned out to be like this. There is no need to improve the mechanical precision at all. Just change the idea and you can succeed."

Although there is no original standard, it is very easy for a skilled craftsman to divide 0.9 cm into ten grids.

It is very simple to measure the unevenness of these ten grids.

This new vernier caliper can measure very fine spacing using this method.

Even the thickness of a hair can be measured accurately!
Everyone at the scene pulled their hair down for measurement, and no one's hair was shorter than 0.3 mm.

In other words, humans have mastered the means to measure the thickness of hair.

"A tiny difference. Everyone uses a tiny difference to describe a tiny difference. Now it seems that we need a smaller unit. This precision of measurement has been conquered..."

Huang Ji thought for a moment: "Measure 0.02? If the vernier has 0.99 grids, a total of 0.01 mm, wouldn't it be possible to measure with an accuracy of ?!"

Lan She shook his head: "That's what the people at the Academy of Sciences said."

"But Lord Wu Hou rejected this idea on the spot."

"Lord Wuhou said that if 9.9 centimeters can be divided into 100 equal parts, there are even hundreds of craftsmen in the Han Dynasty who can do it."

“But even if the difference is measured, ordinary people can’t see it and can’t read the number.”

"Because if the gap is a hundred lines, then it is actually impossible to tell which one is exactly aligned with the top. In the entire institute, perhaps only Yingmu Ting Hou Luoxiahong can use this ruler, so there is no need to waste effort to make something that others cannot use."

It is very easy to tell which of the ten lines is aligned with the upper ruler at a spacing of 0.9 cm.

At a spacing of 4.9 cm, it is barely possible to tell which of the fifty lines is aligned with the upper ruler.

It is quite difficult to distinguish a hundred lines at a spacing of 9.9 cm.

It has exceeded the limits of human vision.

Congressman Tian Yi couldn't help but sigh at Huo Hai's strength. Wu Hou was still the same Wu Hou. In just ten minutes, he solved a difficult problem that so many people in the research institute had failed to solve in five years.

Huo Guang: "If you were smarter, you would have noticed that before the vernier caliper was invented, my second brother said that it could only recognize 0.02mm precision at most, and it couldn't recognize anything finer. What do you think he meant?"

Everyone suddenly woke up.

I'm afraid Lord Wu Hou has already invented the vernier caliper.

However, Lord Huo Hai doesn’t have the habit of directly throwing the results out to the research institute for use.

To put it bluntly, so many people in the institute have been doing research for so many years, but in fact, the technology mastered by the institute is still not as good as the genius ideas in the genius brain of Wu Hou.

Wu Hou has always wanted to cultivate the research institute's scientific innovation and independent capabilities, so he has not announced the results of his personal research products.

Someone at the scene was frustrated: "I thought I became a multi-millionaire with a patent and was a great man. Now it seems that Lord Wuhou has already thought of it, but Lord Wuhou doesn't care about such a small thing at all."

Lan She: “Not only that, while making this new standard, Lord Wu Hou also proposed that the two calipers at the bottom can clamp objects to measure the inner diameter.”

"You can also design two protrusions on the top of the vernier caliper to expand outward to measure the outer diameter."

“Add another steel bar to the tail to measure the depth.”

Everyone looked at each other.

If we say just now that Lord Wu Hou might be a quick-witted person, he could have come up with that genius design immediately.

Well now it's impossible.

Lord Wu Hou had designed this thing a long time ago, but he just didn't bring it out.

It's like a group of people in the desert, thirsty and hungry, saying they want to eat a bowl of noodles.

Everyone knows that it is a pipe dream and it is impossible to achieve.

As a result, Lord Wu Hou served a palace banquet in ten minutes, and told everyone that it could not only quench thirst and hunger, but also detoxify and cure diseases, and that eating it could make people immortal.

It's so outrageous.

Everyone present was convinced.

But the people present were also convinced, and they were more determined to establish the Han Merchants Association to replace the current court meeting!
Because, it is impossible for such a wise and brave Marquis to always exist.

What would happen to this world if Huo Hai passed away one day?
The Han Dynasty is developing rapidly now. Is it the imperial court that is better? Or is Lord Wu Hou more powerful?
The court meeting is an old thing, and the parliament is a new thing, which was also proposed by Lord Wu Hou, so we should replace the old thing with Lord Wu Hou’s new parliament.

Huang Ji was silent for a moment, then said, "After the matter is accomplished, we should place the statue of Lord Wu Hou in front of the parliament entrance and admire it every day, but now, we must compete with Lord Wu Hou."

"If one day, Lord Wu Hou's child grows up and turns out to be as wise and brave as this, then we will accept it."

Now is the early Han Dynasty, not later times.

There were people who doubted the court, but not to such an extent.

By the Ming and Qing dynasties, there was no doubt that anyone would know that most emperors in history were unreliable.

However, since the founding of the Han Dynasty, except for the period of Empress Lü, each generation has been wise and powerful. This gives people the feeling that the emperor is really sacred, chosen by heaven, and each one is powerful.

Therefore, there are not so many people who believe in the system and deny personal inheritance.

However, this Han Merchants Association still appeared. The peripheral members only knew that the core of the Merchants Association was some parliamentarians and even senators.

But they didn’t know that the leader was called Huo Guang.

……

After instructing the research institute on what to pay attention to in the production of vernier calipers, Huo Hai returned to the car with a gloomy face.

There must be someone organizing this behind the scenes.

It is impossible that so many research groups in the institutes need measuring tools at the same time and they all rush to report to Yang Liancheng.

There must be someone behind this.

Huo Hai sighed: "The alliance of capital came so quickly."

Six years ago, these people were all ordinary people, common people in Chang'an City. They might have made a living by farming, transporting garbage, or doing any other job.

Huo Hai’s new business reform has brought them to their current position.

But now, Huo Hai had to fight against them.

Jiang Buyi, who was driving the car, asked, "Master Wu Hou, have you decided to fight them now?"

Huo Hai: "Do you understand their thoughts?"

Jiang Buyi: "They simply don't trust the nobles and the princes, they only trust the system. Trusting people is definitely not a good choice."

Huo Hai shook his head: "This is a society made up of people. What will be the consequences of not trusting people?"

"Now I want to build a society with morality and bottom line, but it's very difficult. No matter what class or identity, there will always be some people who are not bound by morality and have no bottom line. What such people do may not be bad, but those who do bad things will drag down the moral bottom line."

“If the capital of the merchants united together is accomplished, can they themselves be trusted?”

Huo Hai didn't finish his words.

If the struggle only exists within the rules and above the bottom line, then everything in the world is easy to deal with. At most, we can make a rule now and everyone will just not step out of it, and that's it.

But here's the thing.

It is impossible for anyone who has not experienced the Three Kingdoms, Wei, Jin, Southern and Northern Dynasties to maintain the bottom line.

At that time, a person who profits by destroying the bottom line will appear and bring a group of people to destroy the bottom line.

If such people appear on a large scale, society will quickly fall into decline.

History has proven this repeatedly.

Why did people after the Tang Dynasty emphasize morality so much? Was it really because the imperial examination system made Confucianism a must-learn subject that people emphasized morality?
That's just the appearance.

The truth is that everyone knows what society will become if there is no bottom line. Most people do not want to cross the bottom line and cause social collapse, even if it means they will suffer losses.

Only with such a national consensus can we usher in an orderly society.

And now the question is.

Huo Hai couldn't create the history of the Three Kingdoms, Jin, and the Southern and Northern Dynasties out of thin air.

Therefore, Huo Hai simply cannot believe in the concept of institutional progress.

Because it's a very simple truth.

There are good and bad children born to nobles.

But for businessmen, the worse they are, the faster they climb up.

This means that the capitalist system, which seems better, is actually far worse than the feudal system.

This simple truth has been demonstrated three times by the United States.

Other countries? Sorry, other countries have not yet reached the status of world hegemony, and it is impossible for them to form a mature society without external influence to complete this level of moral experiment.

Of course, Huo Hai did not really fully trust the feudal system, so Huo Hai had his own plans.

But at least, there is no option to transfer power directly to businessmen.

Why can’t it be given directly to the merchants? Huo Hai had already demonstrated this when he conquered Nanyue.

If they can even sell the country, what else can't they sell? Selling a few people and buying a little morality, what does it matter?
Jiang Buzhi knew that he couldn't figure out what Wu Hou was investigating.

"My Lord, where are we going now?"

If it were in the past, Huo Hai would not go out at all. He would solve the problem in the Huo Mansion and then throw the vernier caliper to the research institute for them to study.

But now, Huo Hai must come to the institute in person.

The reason is simple: people just like to follow the trend.

To do something, you don't need to say anything, just lead by example.

At the beginning, Dong Yan had the best relationship with the emperor. Whatever he played every day, the nobles also played the same thing every day.

Liu Che liked hunting at the time, so everyone liked hunting.

Later, everyone in Chang'an City followed Wei Qing. Wei Qing was such a boring person, and Chang'an was also boring for a while.

Then after Huo Qubing stood up, his hobby became the hobby of Chang'an City.

Now it's Huo Hai.

Huo Hai now inspects schools, research institutes, and clinics from time to time, and others naturally follow his example in dealing with these issues.

These people can start up education with just a little bit of money.

Huo Hai is now working on a national education plan, but it has not been announced yet. But everyone knows that Huo Hai wants to do this, so it has actually been studied in various places.

Recently, primary and secondary schools are being established in various places in order to stand out and be in the newspapers when Huo Hai's new system is introduced.

Huo Hai thought for a moment and said, "Go to the Steam Engine Research Institute."

Originally, Huo Hai was planning to invite Jiang Buyi to have a big meal.

After all, when the peppers were sent back, Ge San rushed to deliver them to South Vietnam to Huo Hai without stopping.

At that time, Huo Hai divided the peppers into two parts, one part was sent to Shu County and Yelang, and the other part was sent to the north of Nanyue, allowing the two places to grow peppers. At the same time, he asked Ge San to grow peppers in Qi County.

After two years, the production of peppers increased. The people of Chang'an, who loved to keep up with the fashion, heard that Huo Hai liked to eat peppers, so they all started eating them.

There are a lot of spicy things in Chang'an now.

But... the incredible thing is that Huo Hai, who likes to eat chili peppers, has never eaten spicy food in Dahan!
If the chili soup made by the chef of Nanyue Yuelai Restaurant is not considered a spicy dish.

So Huo Hai had been wanting to have a big meal for a long time.

But then I thought, since I'm already here at the research institute, I might as well inspect it a little more.

Especially when I was reading the report documents before, I saw something called a "diesel steam engine". The appearance of this incredible thing seemed to be completely different from the path taken during the Industrial Revolution in the previous life.

Why it's different is simple.

At that time, there were fewer people in England, so they needed extra power, so the steam engine came into being.

But soon they lost the motivation to innovate, so the coal steam engine continued to evolve, but there was no qualitative change.

The emergence of the internal combustion engine quickly replaced the steam engine.

In fact, the steam engine can be miniaturized. As long as diesel or even heavy oil is used as the steam engine fuel, it may not be impossible to innovate the size of the steam engine.

Before the advent of electric motors and internal combustion engines, it was possible to revolutionize train power.

Why is this reform needed?
Because the Xiongnu Company discovered surface oil in the former territory of the Dingling people!
Huo Hai couldn't figure out where that place corresponded to in later Siberia. Anyway, there were oil fields everywhere in Siberia, so it was normal to have oil near the surface.

But what can be done with this oil?

Let them develop oil refining over there?

Huo Hai thought it would be better to build a railway to transport the goods back.

If this railway burns coal to deliver oil, the efficiency is too low, and a large number of people have to go to dig coal along the way, which is not worth the cost. So if we can invent a diesel engine that burns heavy oil or even a steam engine that burns heavy oil, then the problem will really be solved.

At that time, we will mine and produce four things: asphalt rolls, light oil, heavy oil, and carbon black.

Then burn heavy oil and transport the other three things back to Dahan.

Further research will be conducted to produce industrial products.

In this way, it will not pollute the environment, but will also provide a job for the Dingling people who are unwilling to move, and will also make up for the problem of the lack of surface (shallow) oil fields in the Han Dynasty.

There is no rush for this matter. The construction of the railway there is very slow, and the Xiongnu Company will invest a large part of its profits into this railway.

At the same time, trees can be planted next to the railway to prevent desertification.

By the time the railway was completed, the steam engine burning heavy oil would also be completed.

After the internal combustion engine was invented, heavy oil would not be wasted. We could take a branch road from there to Beijing and then to Jinwu Bay, and use the heavy oil as ship fuel.

Originally, heavy oil was only used on ships in the past, but now the Han people can't specially produce iron cans to store useless heavy oil, right?
Besides, ordinary families don’t need this thing. Using a kerosene stove would be outrageous, and using a gasoline gasification furnace in a factory would be outrageous too.

Therefore, whether this heavy oil steam engine can be made is really important.

In fact, this is Huo Hai’s blind spot in knowledge.

In fact, in the past, countries such as the United States and Germany had heavy oil steam locomotives. Germany had a batch of coal-fired vehicles that were converted to burn heavy oil.

Later, when fuel locomotives appeared, these steam locomotives that burned heavy oil were converted back to burning charcoal and were not retired until the 1970s and 1980s.

In fact, for the United States and Germany, given the regional distribution and output of their coal production, the fact that they can actually develop heavy oil steam locomotives has already demonstrated the superiority of steam locomotives.

It's especially good at traction and climbing.

However, the Han Dynasty's current heavy oil steam engine is really a mistake in the technology tree.

Or... maybe it's not wrong, it's just used for different purposes.

Currently, the institute is studying the method of burning heavy oil to reduce the size of steam engines in order to create real cars suitable for driving on the road!

The steam locomotive used in Huo Hai’s wedding was so huge. It was actually just a few scaled-down locomotives running on land.

The amount of rubber used alone is enough to keep it from getting dark.

If it weren't for the fact that Eucommia gum has been used for some years, making the mixed rubber stronger than the rubber from the 1970s, the locomotive would not be able to start.

What they are designing now is a car that is six meters long, less than two meters high and less than two meters wide!

Real cars!
When Huo Hai's car arrived, some people who had seen it already went to inform the police.

As soon as Huo Hai entered the yard, Huang Jiao came forward with a smile.

Huang Jiao used to be a cook. Later he participated in the research and development of steam engines and became a leader in this industry. He successively participated in the research and development of 400-ton paddle steamers and 1,000-ton propeller ships.

However, the research and development there entered a stalemate phase. Three years passed, and the ship steel test was still not completed, so Huang Jiao returned to Chang'an from Qiancheng.

After returning, Huang Jiao became the director of the Steam Engine Research Institute.

When Huo Hai saw Huang Jiao's grinning face, he knew that he was going to "present a treasure".

Huang Jiao bowed and said, "Grand Minister of Agriculture, please come in!"

After entering this courtyard, it is obviously different from other places.

The walls here are thick and high, but the ceiling is not very complete.

It is obvious that they are afraid that the various energy sources they are researching may explode horizontally and cause a chain explosion.

So we have to explode against the sky.

This place is like a maze.

Huang Jiao certainly knew what Huo Hai was here to see, but he deliberately took a detour and took Huo Hai to see other results.

Before entering the first result, Huang Jiao's students had already come out to greet us.

Although Huo Hai sees this kind of admiring eyes tens of thousands of times a year, he always finds it new.

After entering, Huang Jiao pointed to a steel can with a cylinder in the middle and oval ends: "Although you are powerful, Wu Hou, you definitely don't know what this is."

Huo Hai: "Oh, let me guess."

"Did you find that when coal is heated and mixed with water, it produces a gas that is a mixture of multiple substances but can burn. This kind of gas can burn very conveniently. It does not need to be gasified like diesel and gasoline. It is gas itself."

"So you guys want to put it in cans and use it as fuel."

"But the tank can only hold a small amount of gas, and it will be gone after burning for a while, so you thought of pressurizing it and compressing the gas before pouring it in."

"It turns out that if pressure is applied to the inside of the jar, it will be stretched or even torn apart, so you designed the jar to be cylindrical. 'As long as I expand to the limit, it won't be stretched by pressure.'"

After Huo Hai finished speaking, Huang Jiao and his students were stunned for a moment.

Then they both rejoiced.

The students working on this project started studying this new subject because they admired Huo Hai. As they were full of ideas and did well in engineering subjects, they were recommended to the research institute, and were eventually noticed by Huang Jiao and brought into the profession.

This guy’s first research result was the gas tank.

Unexpectedly, now, Huo Hai could see the purpose of this thing at a glance, and what he said was almost correct.

Huang Jiao: "Master Wu Hou, how can this be changed?"

Huo Hai took a few glances inside and quickly retreated behind the wall: "Damn, you guys are really not afraid of death!"

"The gas tank has high pressure inside, so of course we need to design a pressure gauge to see the internal pressure. Otherwise, what if it is over-inflated and explodes? Otherwise, how do you know if the gas inside is used up?"

Water gas is mixed with water, so you can't tell whether it has been used up by shaking it.

To put it simply, this thing is water plus coal and high temperature, which turns into carbon monoxide and hydrogen.

Huang Jiao slapped his head and said, "Yes, the steam engines on the ship all use pressure gauges. We have one ready-made. We can just modify it and use it here."

“Does this thing have a bright future?”

Huo Hai shook his head: "This one..."

Almost spilled the beans.

Huo Hai: "This water gas should be water transformed into some kind of flammable substance. It should be a very important chemical material, but it will take time for us to study its use."

Huang Jiao and his disciples were heartbroken.

Huo Hai: "However, this gas tank is very useful."

"Although it can't be used to hold water gas, it can hold other things, such as... liquefied petroleum gas."

Huang Jiao and the student looked at each other.

Yes, it is compressed gas anyway, why must water gas be compressed for use? Why not liquefied petroleum gas?

This thing, Huo Hai can tell what they are thinking at a glance.

What they wanted was to use water gas as automobile fuel and put it in canned gas so that they could leave a gas tank grid on the car and replace the gas in an instant when it ran out of gas.

This idea is somewhat similar to natural gas cars and hydrogen cars.

But it is destined to be impossible.

In other words, it is possible to build such a car, but it is too dangerous and too expensive to put it on the road.

Huo Hai: "You can use this for your old job. It's too dangerous to use it on a car."

"You never know where the car will be driven to. If it explodes, it will be a disaster."

Huang Jiao felt a little disappointed, but when he thought about the fact that he could use the gas cylinders to fill with liquefied petroleum gas to do his old business, he thought it was okay: "Won't it be profitable if this project is completed?"

It’s easy to tell that coal is too troublesome to burn.

Nowadays, many people in Chang'an live in upper and lower floors, so it is impossible to build an earthen stove weighing several tons at home.

So those people who live in high-rise buildings now use coal briquettes stoves.

But the problem is that coal briquette stoves are prone to poisoning when burning in a closed environment, and more than one coal briquette is needed to cook a meal. If the coal briquette is extinguished after cooking, it would be a waste.

It is not convenient to light a fire over and over again.

If we fill a gas cylinder with liquefied petroleum gas and then use it with the ignition device they invented earlier, wouldn't it be possible to start a fire whenever we want?

There is indeed a huge market for this. If it is launched, and I have the patent in hand, I will definitely make a lot of money.

Huang Jiao patted the student on the shoulder and said, "You are rich, kid."

This kind of project, if listed on the Chang'an Stock Exchange Center and requires investment and listing, will definitely attract a large amount of investment immediately.

As for the fact that oil extraction is too far away from Chang'an, and when this kind of equipment can be used in everyone's home, that is another matter.

Huang Jiao's students were not so happy, and asked directly: "Grand Minister of Agriculture, can my invention be used in the army?"

Huo Hai nodded: "The army also needs to eat."

Besides, gas tanks can indeed be used as weapons, but let’s not do that, it’s too unethical.

The enemies the Han people faced were not worth it.

Huang Jiao led Huo Hai and continued to move forward.

A new experimental project has been launched.

This time, it was a stove that ran on liquid diesel.

In the absence of an internal combustion engine, the use of diesel and gasoline is to burn them, but they cannot be burned directly. They must be vaporized and then burned.

This type of stove needs to be preheated first, and then the preheated pipe can vaporize the diesel before it can be ignited. It is not suitable for home use at all, nor is it suitable for starting alone.

It is suitable for factories, and it will keep burning after it is started.

This stove is quite popular in the market at present.

After all, there are places where there is no coal, but a heat source is needed, such as heating food for canning, heating metal carriage structures, etc., so a gasification diesel stove is needed.

But it is destined to be of small use.

Huo Hai was not familiar with this thing, but he had seen a short video of someone making a similar stove and then boasting that his stove was the best of its kind on the market.

Huo Hai treated it as real and told the researcher the configuration, asking him to give it a try, but it might not work.

The researchers were also very happy that they had a direction.

Finally, Huo Hai continued to move forward and suddenly everything became clear.

The interior of the Steam Engine Research Institute, which studies energy, is too vulnerable to bombing because of its high walls. If Huo Hai had not been the Minister of Agriculture now, he would not have come here to inspect. Even if he did, he would definitely stay away from it.

After a quick look, we finally arrived at our destination.

In front of me is a new car.

It is six meters long, about two meters wide and less than two meters high.

The front of the car has a slightly raised structure, but the front of the car is clearly visible.

Behind the front of the car is the passenger compartment. Although the flat glass structure is rough, it is a real windshield!

There are two rows of seats in the back.

Behind the second row of seats is an enclosed cabin.

And behind it, there is a big bucket!

On top of the bucket, there is a semicircular steam engine stove.

This steam engine furnace is about 1.8 meters long and less than 1.2 meters high, and is placed on the rear bucket.

Huo Hai looked him up and down.

This three-box car structure supported by pneumatic tires...

What the hell!
Pickup truck?!
There is a steam engine burning heavy oil in the back of the pickup truck, is that what you mean?

Huo Hai looked him up and down.

This heavy oil-burning steam engine is different from others. It actually has a shell that covers various components.

Huang Jiao chuckled: "Grand Minister of Agriculture, isn't it more elegant to put this steam engine in the back?"

Huo Hai understood that the reason this car did not have a raised hood was definitely because it was a rear-wheel drive!
But, when heavy oil is burned, doesn’t it need to be preheated in advance?

Huo Hai looked around: "Where's the preheating port? Where's the steam mixing channel?"

Now it was Huang Jiao's turn to be confused.

This was the first time that the Minister of Agriculture saw this car, and also the first time that he saw a heavy oil internal combustion engine. How did he know that there was a steam mixing channel?

Huang Jiao was stunned for a moment and then felt relieved. What was there that the Grand Minister of Agriculture didn't know?

Huang Jiao smiled and said, "I asked Fadi to help me design a steam-driven motor. The motor can generate a tiny bit of electricity, but this little bit of electricity is enough. I can control it with a switch. The steam can open the door, so I don't have to manually switch it on and off every time I start it."

Wow, it’s a one-button start, right?
Huo Hai looked left and right and finally found it: "Before you start, use the oil bottle to preheat the steam and heavy oil at this place, and then start spraying from this position, and you can start it, right?"

This is actually better than the previous generation of cars.

In previous generation cars, if you sat in the car, the cabin would be blackened by smoke, and the rubber seal was useless.

This generation of steam engine is at the back, and it is rear-wheel drive, which is much better.

Also, burning heavy oil is not as troublesome as adding coal manually. Instead, heavy oil and steam are sprayed into the furnace together for continuous combustion.

But the problem is that it is very troublesome to preheat the heavy oil. If you want to start it and run it for only three to five hundred meters, it will be a huge loss.

The heavy oil must be burned up in one trip to reduce the cost per kilometer.

Huo Hai: “How much does it cost per kilometer now?”

Huang Jiao: "If you run the entire 80 kilometers, it will cost 58 yuan per kilometer."

That means one and a half cows per hundred kilometers, right?
Huo Hai: "This prototype car can continue to be studied in the research institute, but it will not be promoted."

This thing won't be cheap. The cost of one car is probably about the same as a thousand-ton ship.

Only a few dukes and the emperor could afford to play with this in Chang'an City.

However, Huo Hai said: "Heavy oil internal combustion engines can be made larger and used on railways."

Huang Jiao looked up: "This is meaningless, coal is much cheaper."

Huo Hai: "It is cost-effective to use it in places where you need to climb a slope or only carry overweight cargo. If the place itself produces oil, it will be even more cost-effective."

Anyway, heavy oil is waste oil in this era, so it would be a waste if you don’t burn it.

As for when the ships can be burned in the future... as long as we don't continue to produce new heavy oil steam engines, but continue to produce coal steam engines, it will be done. The oil production at that time should be enough.

Huang Jiao understood after listening to this. This was to prepare for the expansion of the Han Dynasty. In the future, the railway would be built to the borderland? Is this what it meant?

"I understand. Let's study the heavy oil steam engine locomotive now!"
