1271,How many good things have been left behind by the old empire?
In the evening, the train stopped at Ulan-Ude Station, where Erluzi and Nadya got off the train. This is the capital of the Republic of Buryatia.
Erluzi had already done his homework before coming here. He knew that the Buryat people were the Mongolian Varas living on both sides of Lake Baikal. However, although the place is called Buryat, Slavs actually make up the majority.
This place makes people feel emotional. It is also the place where Su Wu herds sheep.
It has been two thousand years. With the passage of time, everything has changed. This land no longer belongs to us.
A Mercedes-Benz was parked outside the station, and an old man with gray hair was holding a sign with the words "Welcome Mr. Zhao Chunlei" written in Chinese.
Erluzi and Nadya soon saw the old man. After a few people exchanged greetings, they got into the already very old Mercedes-Benz S600.
Although it is well maintained and the car is clean inside and out, this model should be from the end of the last century.
This country does not restrict the import of second-hand cars, so the streets are full of imported second-hand cars from various countries, and the prices are so cheap that it makes the idiot who just came from China speechless.
The old man is also very plainly dressed. He is the director of a car factory.
The old man was driving while talking to the idiot. Nadya was responsible for translating.
The technical data and production lines of the NAMI-012 steam truck are all in this factory. The factory closed the steam truck production line in the 1970s. At the same time, superiors decided to completely eliminate steam trucks. A large number of steam trucks used in the Siberian forest area were discontinued.
More than 20,000 steam trucks were recalled and parked for storage. In the blink of an eye, forty or fifty years have passed.
When Erluzi heard this, he was also a little worried whether these old antiques that had not been used for half a century could still be used. I am afraid they would have long since rotted into a pile of scrap metal.
The old factory director said with a smile. There is a huge underground cave in Ulan-Ude, which was left over from the previous era. These trucks are parked inside. They cannot be blown by the wind or wet by the rain, even after so many years.
, at least one third is still usable.
Those cars that cannot be used can also be dismantled for parts and used to provide spare parts for cars in relatively good condition.
The second idiot asked: "Is your factory still producing?"
The old man sighed and said: "It has been more than ten years since we started working. Young people have gone to Europe, to Moscow, to St. Petersburg. There are better development opportunities there. Now there are only those over fifty years old left in the factory."
The old workers are still there. They usually do maintenance work and can barely make ends meet."
Their country's economy has been very sluggish in the past thirty years. They mainly rely on selling oil, natural gas, ore, and food to maintain the country's financial and economic operations.
Eighty percent of the country's fiscal revenue comes from oil and natural gas exports. Therefore, their country is also nicknamed Saudi Arabia with nuclear weapons.
After the disintegration of the old empire, the entire industrial system collapsed. Now they can no longer even build warships of more than 3,000 tons.
Recalling the strength of the country when they were young, the old man was filled with emotion. Their feelings towards China were even more complicated. After all, they were as close as brothers back then, but they later parted ways.
Today's little brother has already become the world's factory. But the big brother is in poverty. It is true to the old Chinese saying, Thirty years to the east of the river, thirty years to the west of the river.
Regarding steam trucks, the old man said that in 1940, a design bureau began to design the MP-28 steam truck. This was also the first time a truck decided to use a flat-head layout.
This is the first steam truck. In its design, the boiler and steam engine are installed between the cab and the cargo compartment.
The steam engine of this car has a maximum power of 120 horsepower (1500 rpm), a boiler pressure of 100 atmospheres, uses liquid fuel, and a top speed of 40 kilometers per hour.
However, in 1941, the Great Patriotic War broke out in the Soviet Union, and the NAMI factory began to switch to designing military vehicles. The MP-28 plan was discontinued.
Although the MP-28 fell into disuse, its design ideas remained.
As the old man spoke, he arrived at a factory in the suburbs. The idiot looked out through the car window. The factory area was filled with factories similar to those in the old industrial areas in Northeast China. It seemed to be called the Bauhaus industrial architectural art style. It came from Germany.
The grass in the yard is as tall as one person, and there are piles of discarded steel materials everywhere. All kinds of equipment, machine tools, and cars are terribly rusted.
There was only an old man and two wolfhounds watching the gate.
Behind the factory is a mountain. After bypassing the factory building, we soon saw the entrance to the cave.
Several people got out of the car, and a few old workers at the door opened the door, then pulled the switch and lit the lights inside.
Erluzi and Nadya walked in and found that what was said to be a cave was actually three floors of reinforced concrete built between the cliffs of two mountains, each about ten meters high.
It's just that the roof of the building is covered with more than ten meters of sand, gravel and soil. It is covered with trees and grass. Looking from the sky, it seems to be a complete mountain.
When their country was competing for hegemony with the beautiful country, it was not surprising that these factories had such facilities. After all, the automobile industry was the key target of the war.
This huge cavern is more like a three-story parking building. The cars produced by this factory back then were basically driven away after production. The sales volume was very good, and the government ordered enough. This kind of air-raid cavern has been idle.
With.
Later, when these steam cars were recalled, they were placed here. The dismantled production lines were also placed here.
A few people walked and looked around. The second idiot had done a lot of waste collection and was proficient in his business. He got into the cab skillfully and looked around.
I have to say, but the workers of Big Brother are very meticulous in their work. When it was first sealed, the oil seal was very good. There was very little rust, but a lot of dust accumulated.
Because they are all second-hand goods, some of the tires are badly worn and need to be replaced. Even the ones that are in good condition have already aged naturally and are no longer usable. All the tires have long been deflated and flat.
This chapter is not over, please click on the next page to continue reading! The old man is very familiar with the situation in his factory. Although in his era, diesel engine trucks were mainly produced. He himself has not produced such old-fashioned steam engine trucks. However,
He still understands the situation very well.
He continued: "In 1946, after the end of the Patriotic War, steam tractors captured from Germany were tested, and on July 2 of the same year, the results of the tests were discussed by the Ministry of Automobile Industry."
"A month later, the Council of Ministers passed a resolution on August 7, 1947, deciding to "mechanize forestry" and launch a steam truck project. NAMI was assigned the task of designing and manufacturing wood-fired boilers, manufacturing wood-fired boilers.
There is no precedent for boilers in the history of the world's automobiles."
Erluzi also searched a lot of information, and it was indeed like this. The Old Empire was the only one in the world that had such a wood-burning steam engine truck. This should be the pinnacle of technology in that era.
"At that time, I considered that the main reason for using wood as fuel was to save money. Because the transportation of fuel in some remote areas, such as transporting gasoline and diesel to some places where there is no oil, is a very troublesome matter. And it is very troublesome to use the fuel that can be found locally.
The use of fuel can significantly reduce costs."
"Although it was just a truck, the country devoted a lot of research and development efforts at that time. The Automobile and Tractor Department also took on the task. In 1947, they gave NAMI a design drawing of a steam engine."
When the idiot heard this, he couldn't help but ask: "The drawings were only issued in 1947. Wouldn't it be the 1950s for this kind of truck to be mass-produced?"
The old factory director nodded and said: "NAMI-012 was manufactured in the autumn of 1948. The first vehicle was not named. The reason for designing this vehicle at that time was very simple, just to conduct experiments. In order to understand the mechanical structure of the steam truck
, and also to explore the development direction of steam trucks through it. This vehicle can use wood with a humidity of 35% as fuel. However, subsequent experiments proved that even wood with a humidity of 50% will not affect combustion."
This is quite remarkable, wet wood is available everywhere, if you have to use shade-dried or oven-dried wood, there is no point in this kind of truck. It only makes sense if the trees can be cut down at any time.
The moisture content of freshly cut trees is usually 40-200%. Generally, the moisture content of stacked wood is between 8-25%, which is mainly related to the relative humidity of the air.
Therefore, this indicator means that it can be used under natural conditions after a few days of felling trees and piling them up along the way.
The old factory director continued: "At low speed, the engine's torque can reach 240 kg·m, which is five times that of the prototype at that time. A high-pressure boiler, a water tube boiler and a single-expansion steam engine form the powertrain
.”
As he spoke, he opened the power cabin access door behind the cab and saw dusty equipment inside.
"The maximum pressure of the boiler is 25 atmospheres, and the superheated steam can reach 420°C. The steam generated by the boiler enters the three-cylinder steam engine through the throttle valve. After expanding and doing work, it enters the auxiliary turbine, and then flows from here to the upper steam chamber.
The oxygen needed for fuel combustion mainly comes from the cast iron grating under the fuel reservoir. Put the wood on it, and then the wood will automatically fall into the boiler combustion chamber."
Hearing this, Er Lunzi couldn't help but ask: "How far can it run with a full load of six tons by adding fuel and water once."
This issue is very important, it is battery life performance. It is related to practicality.
The old factory director opened the place where the firewood was placed, pointed to the combustion chamber and introduced: "Fill the combustion chamber once and you can drive. However, there are fuel stations every 80 kilometers on the highway and water filling stations every 160 kilometers.
"
Erluzi felt that 80 kilometers was a bit close. But considering that the wood has not been burned, this is understandable.
The old factory director pointed to the metal nameplate on the engine, wiped it with his sleeve, and said to the idiot: "These are the basic performance indicators of the truck."
Nadya translated it. The situation is as follows:
Technical parameters (NAMI-012 steam truck)
Drive mode: 4*2(NAMI-012), 4*4(NAMI-018)
Number of seats: 3
Curb weight: 8300kg
