The emergence of the word kerosene is not because of the fact that the Daheng Empire refined kerosene from oil, but because scientists used coal-to-oil technology to refine kerosene in the early days.

In other words, the earliest kerosene was actually liquefied directly from coal.

However, there are two very major defects in the current coal-to-oil technology, the first is the high cost, and the cost of the oil converted from it is very high, and it cannot be mass-produced at all, which is also an important reason why the coal-to-oil technology has been available for a long time in the past years, but has not been able to be mass-produced.

Compared with the first problem, the second problem is actually more fatal, that is, the current coal-to-oil technology cannot convert the heavy oil required by warships.

This is also the reason why many countries are still not interested in coal-to-oil technology despite the shortage of oil, because warships are now using heavy oil, and coal-to-oil technology cannot be transferred.

However, the Kyle Empire, their naval top brass and scientists' brain circuits are a little different, and they have discovered that coal-to-oil technology can also be used to refine diesel, although the cost is several times higher than that of coal brick gasoline.

However, in terms of solving the problem and ensuring the strategic security of the fuel supply of the domestic navy, a little cost is not a problem at all.

Millions or even tens of millions of warships have been built one after another, and the money for coal to oil is not bad.

So they thought, we don't have oil resources, and there is a risk that imported oil will be blocked at any time.

If the navy's warships use heavy fuel oil exclusively, the strategic risk is too great, and continuing to use coal as the power cannot keep up with the times, so they want to use diesel engines as the power of the warships.

It's not impossible to get an all-diesel-powered battleship in the future!

Similar to the Kehl Empire is the Walya Empire, which is also short of oil, but does not have access to oil security on a global scale.

But the Kyle Empire and the Walia Empire can be said to be a pair of difficult brothers, both of them have rich mineral resources such as coal and steel, so that they can quickly enter industrialization in the industrialization stage, and complete the popularization of steam-powered industrial production and transportation.

But after entering the oil age, they searched all the land of the country, and they were stunned to find no oil resources.

Although the Krull Kingdom does not have many oil resources, it has finally found a small oil field on the territory of the Kingdom Island, although the production capacity is not high, but there are more than 100,000 tons.

And the Olisa Empire also found a small oil field with an annual output of more than 200,000 tons.

Now, the Gafia Empire has also discovered the huge oil field of Kean in its puppet state, the Republic of Kean.

Even the Oran Kingdom found a small oil field with an annual output of tens of thousands of tons in the Louhe Kingdom next door.

The only two powers, Kekel and Walya, failed to find a single drop of oil in their homeland and in the areas under their direct control, although they later controlled the oil of the Mongol Khanate, dividing up the local oil resources, and each of them received more than 100,000 tons of crude oil imports per year.

But this oil is clearly not enough to guarantee their strategic needs.

Crucially, they don't have a way to secure oil imports from overseas.

Even if they were able to obtain a large amount of crude oil imports from the Kean oil fields or from the Great Heng Empire, it would be difficult for them to secure the import of these crude oils by sea in times of war.

If a war breaks out between them and the Krull Kingdom, it is unlikely that their navy will be able to break the blockade of the Krull Kingdom's navy in the face of the Krull Kingdom's blockade.

If war breaks out between them and the Great Heng Empire, it will be difficult to break the naval export blockade of the Kean oil fields that their Great Heng Empire Navy has established on the basis of the Beauva military base.

In other words, even if they can obtain a certain amount of imports in peacetime, they cannot guarantee the safety of oil imports in wartime.

This point actually exists in many countries, even the Krull Kingdom has to worry about the Great Heng Empire's navy blockading the Ken oil field during wartime.

The only thing to worry about is the Great Heng Empire and the Gafia Empire, which are themselves large oil producers.

As for some other second-class powers and medium-sized countries, although they are also short of oil, but their oil demand is also small, and it is enough to hoard tens of millions of tons in peacetime, unlike several large countries, if they complete the use of fuel, I am afraid that millions of tons or even more fuel will be needed a year to really start a war.

The inability to ensure the security of oil supply forced the Kekel Empire and the Walia Empire to set their sights on coal-to-oil technology and try to develop diesel engine technology.

However, their research on internal combustion engines, especially the technical research on diesel engines, is purely for the military, and the market is basically not considered at present.

Unlike the research of the internal combustion engine of the Daheng Empire, it is purely stimulated by the huge industry, agriculture and transportation markets of the people, and more importantly, the Daheng Empire is not short of oil, and the official encourages the research of internal combustion engines and the application of internal combustion engine technology.

The emergence of a series of agricultural machinery represented by gasoline tractors before, and then the emergence of early automobiles, was developed under the guidance of officials, the promotion of capital, and the huge market demand.

This is also the Great Heng Empire has become the first country on the Blue Star to adopt gasoline engines, agricultural machinery and other construction machinery on a large scale.

And other countries do not know the importance of adopting gasoline engine machinery? They know, but they can't help it, they don't have such a big market, and not all countries can build large-scale farms like the Great Heng Empire.

Not all countries can have the same rich oil resources as the Great Heng Empire.

In the first half of the fifteenth year of the reign of Qiansheng, the entire major event on the Blue Star was related to oil, and a Kean oil incident made people all over the world clearly understand the importance of oil.

So much so that a new wave of oil search has been set off on the Blue Star, but whether a new large oil field can be found is a matter of no one can say.

After all, oil resources are even more uneven than those of the coal and steel divisions, and those with more oil resources can make a hole in the oil, and those with few oil resources can not find a drop of oil in the country.

And these have nothing to do with the Great Heng Empire for the time being.

Since the autumn of the fifteenth year of Qiansheng, the diplomacy of the Great Heng Empire has been relatively simple and pure, that is, playing two proxy wars, except for this, there has been no fierce conflict with other major powers.

Well, in fact, these two proxy wars are also quite serious conflicts, but after all, it is not the Daheng people themselves who ended up in the end.

In the eyes of the people of Daheng, as long as they do not end up in person, a proxy war that will break out into a full-scale war is nothing.
