The excellent performance of single-cylinder diesel engines has aroused great interest from Da Vinci and the college students in the mechanical department. But this is not a good thing, and the adverse impact it has brought is that the development progress of steam engines has stagnated.
Because of the super high speed of the diesel engine, teachers and students of the mechanical department are extremely disgusted with the steam engine with a speed of only fifty levels per minute. After all, there is no harm without comparison. Then, most college students of the mechanical department went to study single-cylinder diesel engines. The steam engine was ignored for a while, which made Marin, who learned the news, very depressed.
Marin also knows the advantages of diesel engines, but the supply of diesel is seriously insufficient! Before the technology develops to a certain level, especially before drilling technology develops to a certain level, the supply of diesel cannot be sufficient.
You should know that in later generations, the oil fields were hundreds of meters deep or even thousands of meters deep. However, the current technology could not supply enough diesel at most. Especially some rock layers, without the high-strength drill bits of later generations, they could not drill through.
So, what can I do if I can make a single-cylinder diesel engine? Without oil, the diesel engine is just a piece of scrap iron...
The steam engine is different, this thing burns coal. Marin, who controls the Ruhr area and Newcastle coalfield, has the most in his hands. Moreover, it is very difficult to obtain coal all over the world.
Therefore, even if you know that the diesel engine is better, the steam engine is the easiest to promote it. For this reason, Marin had to adjust his strategy and began to stimulate Leonardo da Vinci and his students to develop steam engines.
Marin promised that the reward for achieving major research results in steam engines is 10 times that of researching diesel engines. The specific standard is that the reward for diesel engine research results starts with 10 gold coins, while the reward for steam engine research results starts with 100 gold coins!
10 gold coins are less than the annual salary of ordinary people (12.16 gold coins), although there are quite a few, but not too many. 100 gold coins are equivalent to more than 8.2 times the annual salary of ordinary people. If an ordinary person has a basic salary of 3,000 yuan in his later generations, 12 gold coins are equivalent to 36,000 yuan. 100 gold coins are equivalent to 300,000 yuan in soft sister coins...
A phased general research result will be rewarded with 300,000 yuan. This standard will be tempted by those professors in future generations...
And Marin even promised that if anyone can successfully get the steam engine on board or successfully create a practical steam engine train, the reward will be 1,000 gold coins, and the top will not be capped...
In other words, Marin's reward for steam boats and steam locomotives starts at 3 million, which is very generous...
For diesel engines with higher technical content, Malin cut 10 times the reward. The ordinary reward is only about 30,000 yuan in later generations. For the already high-paid engineering and technical personnel, it is really not attractive...
After this stimulation, most of the mechanical college students went to study steam engines. But there were also a few pure scholar-type college students who didn't care about rewards and were determined to continue to develop diesel engines. Marin was not disappointed. After all, one day, diesel opportunities became the mainstream. At present, most people are studying steam engines, and a few people are studying diesel engines, which is exactly what Marin hopes to see most.
However, Marin was also unwilling to accept that the diesel engine with excellent performance could not be used on a large scale. Then, he suddenly thought of the very popular biodiesel technology in the 21st century.
The so-called biodiesel means esterification of vegetable oils and alcohols (mainly methanol or ethanol) in an alkaline environment to obtain biodiesel with very similar combustion performance to diesel.
Biodiesel has good environmental protection, no sulfur, and does not pollute air, which is the key research direction in the 21st century. However, because the price of vegetable oil in later generations is relatively expensive and the cost is higher than that of ordinary diesel, it has been difficult to make a big breakthrough.
Marin remembers watching an agricultural program, introducing a plant called jatropha. The oil squeezed from the fruit is easy to process into biodiesel, and the quality is quite good, which is better than the domestic No. 0 diesel.
It is said that this jatropha tree is native to tropical areas in southern North America. The fruit is toxic and can cause dizziness, vomiting and diarrhea after consumption. However, its fruit has a high oil yield and is suitable for processing into biodiesel.
In fact, the jatropha is the American version of tung tung oil, which has a very similar characteristics to tung oil, and the fruit oil press is also a bit similar to tung oil.
Moreover, tung oil can actually be made into biodiesel. Marin has read a report in his previous life that it seems that tung oil and methanol are used for esterification, and reacted for N hours under a strong alkali environment of potassium hydroxide...
However, the jealous tree is emphasized on TV, but not on tung oil tree. It can be seen that jealous tree must have its superiority as a source of biodiesel raw materials.
In fact, processing tung oil into biodiesel is not much worse than that of jealous trees. But the problem is that tung trees have high environmental requirements and only grow well in southern China.
Later generations, Paraguay and Argentina, both introduced oil barrels, but the result was that the oil barrels did not grow well in the southern part of the United States, and the quality of the tung oil produced was poor. In the South American environment, the quality of the tung oil produced in Paraguay was OK, but it was not as good as that produced in China.
The reason why jatropha is promoted on TV is because of its strong adaptability. The TV program said that jatropha has low requirements for the soil environment, is also very resistant to diseases and pests, and has strong adaptability. I am afraid that this is the main reason why it has been vigorously promoted.
Anyway, Marin remembers that the oil squeezed from the jeprosy fruit is esterified with methanol or ethanol under KOH and high temperature environment. As for the reaction for a few hours, the proportion, and how to remove the alkali afterwards, he doesn't know. After all, he is not a professional chemical worker.
However, if you know these, it will be easier to do. Anyway, as long as the raw materials are sufficient, try a few more times, or even hundreds or thousands more times, you can always find the ratio and reaction time, as well as the subsequent purification methods.
Anyway, Da Vinci has taught a group of chemical engineering students now. When there are more chemical engineering students later, they will be divided into a group of specialized research on this, and they can always find a way.
According to the TV program in the previous life, the oil squeezed from the fruits of a japrostitute can produce 500 kilograms of biodiesel, which is half a ton.
If he planted his 10,000 mu of jealous trees, the annual diesel production would be 5,000 tons! A 12-horsepower single-cylinder diesel engine only consumes two or three liters of diesel per hour. Even if it is not stopped for a moment, it will only consume about 26,000 liters a year. The density of No. 0 diesel is 0.85 kilograms per liter. In other words, a 12-horsepower diesel engine will only consume about 22 tons of diesel if it does not last for a full power throughout the year. But in fact, a single-cylinder diesel engine will cost about three or five tons of diesel a year.
In this way, 10,000 mu of biodiesel produced in jealous trees can supply thousands of diesel engines for one year. If the biodiesel production is expanded by 100 times...
Although biodiesel costs higher in later generations and is not very cost-effective, for Marin in this era, whether there is any one or more important questions. As for the cost, it is secondary.
Even Malin came up with an exaggerated scene of using a hand-held tractor to attack the enemy formation. Of course, first of all, he had to have a professional mechanic team to carry a single-cylinder diesel engine onto the vehicle and create a rotten agricultural vehicle similar to the "Four-Dislikes" in later generations. Then, wrap it in iron and you can use it as a domestic tank...
Thinking of this, Malin's saliva was about to remain. Even the "four nostalgic" used in later generations was enough to destroy any enemy's battle formation in this era...
However, after waking up, Marin understood that if you want to create a "chariot" like "four nosys", Temeo first cultivates a qualified mechanical style. However, in later generations, Da Vinci and his mechanical students are far inferior to even a mechanical apprentice. Therefore, the task is long and hard...
But if the "Four Dislikes" are studied and the production of biodiesel is sufficient, the whole world will probably be shrouded in the shadow of the tractor tanks in Beihai Kingdom. Thousands of tractors hit you, and I'll ask if you are afraid?
...
Of course, that is just a bright future. First of all, to realize that kind of bright future, Marin needs to send someone to find the jatropha tree first. Although he knows that in southern North America, it is also very difficult to find.
Then, even if you find the jatropha tree, it will take several years to bear fruit. Then you squeeze out the oil of the fruit and use it for the chemicals to conduct research on the esterification reaction... In short, it will take a long time, and it will probably take decades. Maybe Marin can't see it alive...
