Chapter 262 Single-cylinder burnt ball diesel engine
Sending young children to study in Austria-Hungary from an early age was Gao Hongsheng's decision after deep thought, and Austria-Hungary was generally very open, not as rigorous and rigid as Germany, not as romantic as France, and less British arrogance and mercenary than the United States
On the whole, Austria-Hungary was a very tolerant empire, as can be seen from the composition of its population.
It is mainly made up of eleven ethnic groups, of which 24% are Germans, 20% are Hungarians, and the other races range from 13% to 3%, each with its own characteristics, and still retain their own language, and in this respect the Austro-Hungarian Empire did a good job.
Moreover, the architecture and art of the Austro-Hungarian Empire also have a certain status in the whole world, especially in the construction of railways and highways, which is ahead of other countries, and the military industry is also quite developed, the Skoda Arsenal is a famous military factory before World War II, and the artillery it produces is more advanced than Krupp.
If Gao Hongsheng adopts the teaching methods of later generations, it is not impossible to cultivate a group of talents, but the talents he has cultivated are definitely inferior to those children who study abroad in terms of abstract thinking such as creative power and imagination.
This is a matter of vision, that is to say, a person who is just cramming in school to teach, and a child who has grown up in a different environment since childhood.
At the same time, these children who have studied abroad grow up and use the cramming duck teaching of later generations, and after the students they teach communicate with each other, the two sides are likely to encounter sparks full of inspiration in science and technology.
Austria-Hungary is easy to solve, but there are still some troubles at home, mainly because the Chinese at that time still had a strong resistance to sending children abroad to study at an early age, which can be seen from the experience of the Great Qing State recruiting young children in the United States, the officials who recruited young children in the United States at that time, but it took a lot of effort, and finally there was no way to recruit a group of children from the south to the United States, but it is not the era when everyone is trying to send children out now.
This is the problem of concept, at the same time, the young children selected at that time are all selected to have a certain cultural foundation of the children have a relationship, the children who can go to school in that era are all families with a certain economic strength, their conservative thinking does not think that there is anything good about sending children abroad to study, China is a big country, the center of the world, how can you learn Western prostitution skills, what is the use of learning, and you can't be an official to take the imperial examination.
Gao Hongsheng is different, he is ready to recruit from the children of the toiling masses at the bottom to study in Austria-Hungary, it doesn't matter if you can't read or can't, you can send a few Chinese to follow them to Austria-Hungary to teach them, these children are mainly learning Western science and technology, and not sending them abroad to be literary scholars, knowing how to write Chinese characters, how to express it, there is no need to be pedants who can chant poetry.
He wanted engineers, technicians, basic management personnel and other very basic talents, not high-level artists, writers, there were too many people in the Qing Dynasty at that time, and even too many in the future, he did not need to cultivate such talents.
The children of the toiling masses at the bottom can't even eat, so he doesn't believe that sending them to school abroad is no better than starving to death at home, not to mention that he will let the children come back every three years to see their families or something, and he is not short of that little money, otherwise, in the end, it will be worth the loss to train a group of white-eyed wolves to come out.
As Ferdinand's reward for his help, Gao Hongsheng generously gave him a model of a tracked tractor, a model of a four-wheeled tractor, and a single-cylinder burning ball diesel engine.
This gift can be said to be big or small, the burnt ball diesel engine or hemispherical diesel engine was invented by the Englishman Stoart as early as 1890, and there have been a large number of finished products, mainly because of the initial internal combustion engine, although there are shortcomings of this and that, but there is an advantage that no one needs to watch, and it can work for several hours without being served.
At that time, the steam engine was a very troublesome thing, not only did people have to keep filling the boiler with coal to keep it burning, but also paying attention to the level of the boiler water.
After all, the burned-ball diesel engine belongs to the internal combustion engine, which is small, simple, heavy, and noisy, but once this thing is running, you can leave it alone, and it can continue to work until the fuel runs out.
Gao Hongsheng did not provide Ferdinand single-cylinder diesel engine is also no way, the material strength and processing accuracy of this period can not process the modern single-cylinder diesel engine, just an oil-resistant oil seal is likely to become an obstacle, not to mention the ultra-high precision high-pressure oil pump nozzle, not to mention just precision casting cylinder block, can make those engineers at that time worry to death.
Burning ball single-cylinder diesel engine is not this trouble, rough and simple is its noun, cast cylinder block, cast piston, cylinder block is also simple, material requirements are not high, processing difficulty bottom, precision requirements are small, the most important point is that it does not have high requirements for fuel.
In the era of Gao Hongsheng, the petroleum processing technology is still in the initial stage, the main use of oil is to extract kerosene and grease, at that time can be called the era of lamp oil, gasoline and diesel and other petroleum products are still in the primary era, diesel has not been divided into light diesel and heavy diesel, just a general division of diesel, so that the source of oil for single-cylinder diesel engine has become a problem, always can not be in order to produce single-cylinder diesel engine to transform the refinery.
The main reason is that its combustion chamber is different from that of a single-cylinder diesel engine, its combustion chamber is a concave cast steel combustion ball, and the burning ball should be baked with a blowtorch for 5-10 minutes before starting the machine, and the oil sprayed from the fuel injector will be atomized into white smoke due to the high temperature in the burning ball.
If the diesel engine is cold start, then the burnt ball diesel engine belongs to the high temperature start, so as to avoid the problems caused by the substandard oil products.
Gao Hongsheng provided Ferdinand with the tractor model is the 55 type and Poland 45 type tractors imported from Hungary in the 50s of the 20th century.
The horsepower of the Polish 45 type tractor reaches 35 horsepower, and the 55 type reaches 55 horsepower.
It is impossible to open up the wasteland in the Great Northern Wilderness without using mechanization, the land in the northeast is large, and the land is so big that the tractor is likely to drive along the straight line for a day, and it is likely that it will not reach the ground for a day, if it is used to manually reclaim, I don't know how to do it until the year of the monkey and the month of the horse, not to mention that the agricultural time does not wait for anyone, God does not care if you plough the land, sow or not, harvest or not, when the old man changes his face, you will do it in vain in a year.
Of course, these two kinds of tractors have a big problem is that the vibration is particularly loud, the sound is particularly loud, because it is a single-cylinder two-stroke, after the tractor starts, especially in the state of the small throttle, the whole fuselage will tremble up and down like a sedan chair, and move back and forth, when driving, sitting on the car can obviously feel the rapid shaking of the tractor, as a result, many drivers suffer from stomach prolapse after a period of time.
How loud is the sound of its operation, can be described as thunderous (not the impact of the cylinder, but the movement of the exhaust pipe), especially at night, the sound is usually more than ten kilometers away, in the fifties of the 20th century, people said that "it is the single-cylinder tractor that vibrates the small peasant economy." ”
At the same time, there is a problem that it needs to be baked with a blowtorch, and later the manufacturer made some improvements, and a protective cover was installed on the gas plug on the cylinder head, and a burning rod with phosphorus and sulfur was built into the cover, and the burning rod was screwed in after ignition, so as to preheat and start, so that there was no need to use a blowtorch, and the ashes of the burning rod of this material after burning would be coke, and would not fall into the cylinder and lead to wear, as long as the fuel consumption rod was unscrewed down and invaded into the water before the next start, the coking ash could be loosened and dug out. It is also possible to add a multi-stage spark plug to the side of the cylinder head so that the rocker can also be started, and later a starter that can be reversed can be added to drive the flywheel.
Of course, there are other problems, in response to the problem of vibration, Gao Hongsheng adopted the method of later generations, added a pair and two pairs of balance shafts, and used counterweights to offset the inertia of the piston connecting rod group, reduce vibration, and a design defect of the Polish 45 type was also changed, and the brake drum was installed on the reduction shaft, which avoided the problem of difficult braking because the brake drum was installed on the rear axle of the original car.
At the same time, a major problem of the Hungarian-55 crawler tractor has been transformed, that is, it has fallen into a mud pit, and when the front is low and the rear is high, the phenomenon that the light gun cannot be used to start the car, which makes the applicability of this kind of tractor more extensive.
Poland 45 type wheeled tractor, the speed of travel is fast, the transportation of cultivated land can be, the 55 type of horsepower, or crawler, the front of the shovel and other systems can be used as a bulldozer, at the same time the crawler tractor is suitable for a wide range of terrain, plus the steel plate to resist rifle bullet shooting can also be used as a light armored vehicle, although the movement of this thing is a bit too big, but it is good to scare the children, not killed at least can be scared half to death.
However, the weight of these two things is not light, the weight of the 45 type is about four tons, and the weight of the 55 type is directly more than six tons, which is really a representative of the stupid big black and coarse, and it also costs oil, but the cheap crude oil in this era can be described as pitiful, a barrel of tens of cents, and the cheap one can.
