Occupy the pit...... It's too late again, so I can only occupy a pit first, change it back in about 15 minutes, please refresh it after 15 minutes, sorry.

Originally, the development of the human oil industry originated from the refining of kerosene. However, this does not mean that Marin has developed a kerosene lamp and mastered the oil refining technology, which can make the oil industry of the North Sea country take off rapidly.

The main reason is that there is no technical support from the whole society. After all, in 1859, when the modern petroleum industry originated, human steam engine technology had long matured, and too many mechanical experts had emerged. Therefore, after the oil is refined, it can be put into application very quickly. In addition, the technology for oil exploration and oil extraction can be rapidly developed.

But in this era, I'm afraid that only Marin, a traverser, knows what the oil industry is. Even Leonardo da Vinci, the smartest man in the world, knew nothing about the oil industry.

In particular, oil exploration and drilling technology is limited by technology, and it is difficult to make great progress. Even if Marin had developed the rotary drilling technique, he would only be able to drill shallow oil wells at a depth of 100 meters. Most of the large oil fields in later generations could not be developed with this technology. The oil wells that can be developed are only those places where a limited number of oil seedlings are exposed to the surface, such as Titusville, such as Galicia, such as Baku, such as out of sulfur pits, such as extension......

But the production of such shallow wells is not high, and it cannot meet the huge demand for kerosene lamps. Therefore, in the early days, the application of kerosene lamps was not very widespread. Of course, when the Beihai country has trained several generations of mechanical engineers and the technology has gradually matured, it will be able to drill deeper oil wells and get more oil.

In fact, with Ma Lin's memory, the 12-horse Changchai walk-behind tractor bought by the old horse's family in the previous life can also be copied by craftsmen. After all, now that vulcanized rubber is available, as long as it takes a little time and allows the craftsmen to go all out, it is still possible to replicate that single-cylinder diesel engine. At most, it is because of the rough technology, which leads to frequent problems with the machine, just like the current imitation Watt steam engine.

But the biggest problem is not here, the main problem is the supply of diesel. With the oil production of only one barrel per day from the Galician oil fields, the diesel oil extracted can be used by a walk-behind tractor for a day at most. This is still calculated according to the highest diesel refining ratio of 30%. But with Marlin's workshop-level technology, it would be nice to be able to refine 20%.

Even if a walk-behind tractor is only driven for 8 hours a day, it can supply two or three tractors at most. So, what can this change? The supply capacity of two or three single-cylinder diesel engines is ...... Well, it's still useful, at least, to accumulate technology......

As a result, Marin began to organize a large number of craftsmen and began to copy their family's 12-horse walk-behind tractor that often went wrong in his previous life......

Why did Marlin insist on a 12-horsepower single-cylinder diesel engine when there was an extreme shortage of diesel? Not for wide application, but for its rotational speed!

Yes, no matter how bad a single-cylinder diesel engine is, the speed is much stronger than that of a steam engine. The current Watt steam engine in the North Sea country only rotates at a speed of just over 50 revolutions per minute. This speed is not much different from that of a hand-cranked machine. The single-cylinder diesel engine is different, Ma Lin remembers that in his previous life, his Changchai had 12 horsepower, and the speed was as high as one revolution per minute!

This speed, in large-scale industrial production, may have little application value because of the lack of oil. However, if you use it to drill the barrel......

Yes, Marlin just came up with the idea of drilling the barrel. For rotary drill bits, the faster the rotational speed, the stronger the drilling penetration. If a single-cylinder diesel engine with a speed more than ten times faster than the current Watt steam engine is adopted, the efficiency of the drill barrel will be greatly improved. It can even be considered for drilling cannon barrels......

Not much, as long as there are so many single-cylinder diesel engines used to drill the barrel, it is basically enough. After all, the scale of the Beihai ** team is just like that, and the demand for gun barrels is not high, and tens of thousands of gun barrels are enough. Unlike later generations, some of the rifles mounted in the column often have tens of millions of levels, and the number of AK47 even exceeds 200 million......

In addition, the single-cylinder diesel engine is also very good for drilling wells. In the previous life, the drilling rig in the countryside used a steel frame with a small diesel engine on it to drive the rotating drill bit to press down. I haven't seen the authentic oil drilling machinery in Marin, but I have seen this kind of drilling machine used in the countryside. Although this drilling rig can only drill tens of meters deep, it is enough to drill shallow oil wells in the early days. Best of all, it's much faster than the traditional toning techniques that are now popular. Ma Lin remembered that in his previous life, the well-drilling machine commonly used in the countryside was no problem to drill two irrigation wells a day. However, if the ancient gravity hard smashing drilling technology is adopted, according to the technology of Zhuo Tube Well, it is estimated that it will take 60 or 70 days to drill a 100-meter-deep salt well...... This efficiency is incomparable......

Of course, all this is the ideal state. And the reality is ......

Ma Lin finally commanded the craftsmen to imitate the 12 horses of Changchai single-cylinder diesel engine, as a result, during the trial operation, there was a problem with the bayonet design of the crank (Ma Lin did not pay attention to this small detail in his memory), and the crank failed to take it down in time, and then, when the diesel engine turned up, the iron crank flew out, directly killing a nearby craftsman......

The next day, during the test run, the huge flywheel of the diesel engine, because the riveting was not firm, flew out directly......

Fortunately, this time everyone was mentally prepared, and the bunkers were added, and there were no casualties.

In addition, the quality of the original vulcanized rubber transmission belt made by Marin seems to be unstable, and the wear resistance does not seem to be very good. No, it suddenly broke off after two days of operation...... Luckily, Marlin has sisal fibers as a backhand. After switching to a transmission belt braided with sisal fibers, it really worked better......

Seeing these unpredictable consequences, Marin was also terrified. It seems that the backwardness of the overall mechanical technology foundation of the society makes it possible to have many problems that Marin has never seen in his previous life after the machine is manufactured. Moreover, they are all low-level problems that Marin can't think of.

For the sake of safety, Marin still left these problems to the craftsmen to deal with. Moreover, this process is also a process of growth technology.

But in order to prevent further accidental deaths, Marin asked the craftsmen to not only place bunkers when testing single-cylinder diesel engines, but also to wear a full set of plate armor as protective clothing to avoid accidental death by the machine......

In fact, Ma Lin did not know that when the new China Kingdom was first established in later generations, the machinery industry was developed in various places. Even with the guidance of Maozi's experts, there were still a lot of impromptu accidents. And with every machine accident, someone can be injured or even killed. Over the decades, I don't know how many machine factory workers have broken their fingers or entire hands, and there are also whole people who have been killed by machinery......

There is no way, at that time, the country was newly created, and the foundation of the machinery industry was equivalent to nothing, and it was not much better than Marin now. The only thing that is better than Marin's current situation is that there is mature foreign theoretical guidance, as well as many advanced prototypes from abroad as a reference. Rao is like this, there are still many workers in Xinhuaxia because of machine problems, or improper operation, there have been many accidents, resulting in many casualties. Ma Lin read a report in later generations that said that in Wuhan alone, the number of casualties in industrial accidents reached 50,000 in a few decades. Among them, the highest proportion is limb disability (mainly hand......
