Chapter 882: 400 kilograms of coal consumed per 100 kilometers!

The two of them worked together to put the front of the train on the track, and then pushed the front of the train along the rails to the open space in front of the main hall. Then Lin Fei walked up to everyone and introduced it.

"Chief, this is the model of the first generation of the Endeavour steam locomotive."

Luo Chong came to the front of the car with Luo Lan in his arms and squatted down. Seeing this, the others also gathered around. After listening to Dali's introduction to this kind of car, everyone also paid attention to it and wanted to see what was so powerful about this vehicle that could be called a land boat.

Adults and children squatted in a circle and surrounded the train model in the middle, and began to look at it carefully.

The whole car is painted black, and the cylindrical boiler part is painted red, with black paint embellished on it, plus some original metal parts, it looks very beautiful.

The structure of the whole car is similar to the drawing given by Luo Chong, but because it is a model car, and this car uses a calcium carbide gas boiler, not a coal-fired boiler, so it is slightly different from the drawing.

"Chief, the Endeavour uses a 4-6-8 wheel layout, with two pairs of small-diameter guide wheels in front, and a high-pressure cylinder on each side of the middle of the guide wheels. Behind the guide wheels are three pairs of large-diameter driving wheels, which are also power wheels, responsible for providing power to the entire train. Behind them are four pairs of driven wheels, which are mainly placed under the coal-water car to play a role of bearing and support, because the coal-water car is heavier. Overall, there is no difference from the drawings."

"Have you measured its speed? And what is the load capacity? If it is in actual proportion, can it meet the technical parameters? By the way, didn't you say that there are still ten carriages? Why don't you bring the carriages here?" Luo Chong is very familiar with these data, and Lin Fei obviously knows this problem. He introduced it in such detail mainly for others to hear.

"Oh, there is no hurry for that carriage. It's not too late to light the furnace and then hang the carriage. Let me introduce the car first." Lin Fei paused and continued.

"We haven't started trial production of a normal-scale car yet, so we can't guarantee what parameters it can have, but this model can run at a speed of 50 kilometers per hour. As for its load-bearing capacity, don't look at this small model. It can pull a ton, or 2,000 kilograms, without any problem. However, it is on flat ground. If it is uphill, it is probably no problem, but it certainly can't run that fast." As soon as Lin Fei finished speaking, the county governors around him couldn't help but be surprised.

"Such a small thing can pull 2,000 kilograms? It's hard for a horse to pull 2,000 kilograms, right?!" Yun Zhi asked in disbelief.

You have to know that in their inherent concept, what are the things that pull carts? Either cows or horses, but even cows and horses dare not say that pulling 2,000 kilograms is easy, and now Lin Fei actually said that this thing in front of him, which is not even as big as a dog, can pull 2,000 kilograms. How can they not be surprised.

This is just a model. If it is enlarged a thousand times according to what Dali said just now, wouldn't it really catch up with a sailboat? !

"Of course, if you don't believe me, we can try it right now. Didn't the people from the first institute bring a scale just now? Let's put the carriage on and let the people sit on it to see if this car can pull it."

Lin Fei was very confident, because they had already tried the model of this car in Xingang County, otherwise they wouldn't dare to say it so firmly.

Yun Zhi didn't refute anymore, he also wanted to see if this car was really that powerful.

Luo Chong was calculating the parameters that Lin Fei had just reported, 50 kilometers per hour, which is 25 kilometers per hour.

What does 25 kilometers per hour mean? It's about the same speed as an electric bicycle, and the normal running speed of a horse is also about this speed. To be honest, let alone this is just a model, even if a real car can run so fast, it can be put into practical use.

Luo Chong decided immediately, "What are you waiting for? Let's see if the track has been laid. If there is no problem, let's get it moving quickly. It always feels dry to just introduce it like this. It's more intuitive to see it running."

"Yes!"

Lin Fei agreed immediately. He first asked if every joint of the entire track was fixed, so as not to derail and overturn halfway. Then he asked people to move all the carriages outside and hang them all behind the front of the train. Then he started to light the fire and the stove.

Luo Chong also asked the maid to turn on the water. Lin Fei personally poured the boiling water into the boiler of the front of the train, and then poured calcium carbide into the acetylene generator inside the "coal car". Then he opened the water supply valve with controllable flow rate, and the clean water entered the calcium carbide box, reacted chemically with the calcium carbide inside, and immediately released combustible acetylene gas.

These gases then flowed into the nozzle inside the boiler along the pipe. Lin Fei calmly used a wooden stick with an open flame to ignite it. With a slight sound, the boiler suddenly ignited an incandescent flame and began to heat the boiling water in the boiler.

This train model has a total of six control systems, one to control the water supply speed in the acetylene generator, and one to control the outflow speed of acetylene gas. These two systems control the size of the flame in the boiler.

Another pair controls the flow of steam into the cylinder, that is, the speed regulation for accelerating and decelerating the car. There is also a corresponding steam brake device, and the last pair is reverse and whistle.

Lin Fei sat in the coal and water car position of the model car. After igniting the boiler, he directly moved the valve and blew the whistle.

Woo woo woo————

The small train issued a loud whistle, attracting the attention of everyone in the yard. Luo Lan in Luo Chong's arms, Xiao Luo Cheng at the door of the main room, and the child of the cripple family ran directly towards the train.

Puff————

Just at this moment, a stream of steam was emitted from both sides of the train. Because it was a gas boiler, there was no black smoke even though there was a chimney on it.

"Chief, the boiler has been lit and can be started now. Do you want to take a ride?" Lin Fei rode on the train and looked at Luo Chong expectantly.

Luo Chong:

Are you kidding? Although he was also very interested in this train, he was asked to ride on the train in front of so many people? How embarrassing!

Of course, if he waited until all the outsiders left, it would be fine for him to take the children to play, but it was definitely not possible now.

"I won't get on it. It's better to stand at a distance and observe than sit on it. Anyone who wants to sit on it can try it. Don't you all want to know if it can carry two thousand kilograms? Now is your chance.

Also, let me tell you, this is a project that our Han tribe will develop for the next few decades or even hundreds of years, and even for generations. As local officials, you county governors should experience it first, and then tell me how it feels later."

Luo Chong directly rejected Lin Fei's invitation at first, and then began to trick the county governors present to sit on it, otherwise everyone would feel ashamed, and what if no one wanted to try it?

Originally, they really thought so. In front of so many people, playing with this thing, even if it is very important, it is just a toy now, and everyone is a little embarrassed. But now it's all right, the leader asked them all to experience it. Since everyone wants to sit on it, it doesn't matter. Anyway, everyone sits on it, and no one laughs at anyone else.

"Yes!" The county governors answered in unison.

"My Lords, it's better to tidy up the hem of your clothes first. This model is relatively short, so as not to get the hem of your clothes caught in the wheels." Lin Fei reminded them quickly.

Everyone began to tidy up their clothes silently, and then arranged the front and back seats modestly. After they all rode on this train, they were even more skeptical. It was originally said that there were ten carriages, but because they wanted to try to load two thousand pounds, they finally hung sixteen carriages on it. Such a small front, with so many carriages, a full ten meters long, made it like a python. Is this thing really able to pull it?

But just when they were doubtful, Lin Fei, who was sitting in the front, suddenly blew the whistle, and the small train whistled, and then threw it forward suddenly.

Huh, huh, huh, huh————

The cylinder began to slowly accelerate, making a panting sound, and the small train also began to move forward slowly, and then began to gradually accelerate.

"Oh! It really pulled it?! This iron car is really amazing. There are seventeen of us, each weighing more than one hundred pounds, so it must be more than two thousand pounds. Such a small thing can really pull such a heavy weight!" As the vehicle was moving, She Xin's body suddenly leaned back, and then the car began to move forward quickly.

"Wonderful! If I can make this car bigger and put it in the mine to transport ore, I can increase the coal production in Dongxin County by more than ten times, and I can also save a lot of livestock." Jing Yan sat on this small train and ran along the track, and couldn't help but sigh.

"I just don't know how much it consumes. Compared with the transportation by cattle and horses, the cost is better or worse. I just saw that this car seems to burn calcium carbide. Does it use a lot of calcium carbide?" Yun Zhi also saw the powerful power of this steam iron car, and then began to calculate the consumption, wanting to know the operating cost of this car.

"No, this is just a model car, so it uses calcium carbide. I heard from the people in their research institute that such a real car, a big car, burns coal. As long as the coal is used to boil water, it can drive the iron car forward." Dali heard Yun Zhi's doubts and explained directly.

After Lin Fei, who was sitting in the front and controlling the vehicle, heard their discussion, he also tilted his neck and rushed back to say.

"What the county magistrate said is right. This finished car is powered by coal. It can travel 500 kilometers with a full tank of water and 2,000 kilograms of coal. It can run all the time without rest."

Yun Zhi did some quick calculations in his head. Water is not valuable, right? The Han tribe never charged for water, so coal is all that is needed.

"By this calculation, this car consumes 400 kilograms of coal per 100 kilometers? If it is based on this load, it is a good deal!"
