The first thousand nine hundred and thirty-six chapters of the Tang Dynasty ahead of the theory
Professor Lin continued: "This shooting scheme can significantly reduce the size and weight of the gasoline engine compared to the gas engine, and the safety is much better than the gas engine because of the gasoline used."
"Of course, there are still difficulties in trial production, and even mass production is not possible, and there are defects such as short lifespan and malfunctions, but this is an inevitable stage that new offices need to go through."
"We will conduct more tests on this solution in the future, and manufacture multiple test samples with different focuses for simultaneous testing to shorten the development time. If nothing unexpected happens, we will be able to complete the preliminary test within half a year.
Then determine the research route.”
Song Tao heard that the research route could only be determined after half a year of testing, so it was still unknown how long it would take to come up with an engineering prototype plan. As for its practical use, it was estimated to be even longer.
But he is not here to rush the development progress of the internal combustion engine project. He is just here to understand and report to the Holy Emperor.
So he won't say anything that shouldn't be said at all.
He just asked in detail about the research and development progress of the internal combustion engine project, not just gasoline engines, but also diesel engines and kerosene engines.
However, Professor Lin is only responsible for the gasoline engine, diesel engine projects and kerosene engine projects. He is not responsible for them, so the person in charge of the other two projects will explain.
Song Tao stayed in the internal combustion engine laboratory for a whole afternoon before leaving with a thick book of notes.
Although it was already late, he still returned to the Hanlin Academy and took a few of his subordinates to work overtime to sort out the collected information.
The next day, he received a telegram from his subordinates who were sent to Hangzhou to learn about the gas engine project. However, the telegram did not say anything too detailed. Instead, it said that they had collected information overnight and would take the train back to Jinling today.
That night, Song Tao waited for the information brought back by his subordinates who went to Hangzhou, and then led a group of subordinates to work overtime, and finally produced an internal combustion engine research and development report.
This report appeared on Li Xuan's desk early the next morning.
Li Xuan didn't know that his secretaries had been busy collecting information for two days. This was not what he needed to know. He only needed to know the development progress of the internal combustion engine.
After a brief look, the first thing is about gas generators. The main research on this thing is Hangzhou Power Machinery Company. This company was a purely private enterprise at the beginning. Later, the Royal Assets Department invested in the company and obtained part of the shares.
The company's beginning was to develop gas engine tanks for the navy. However, the gas engine tanks were unreliable. Lin Ziran personally killed this project long ago. Later, the company turned its target to industrial gas engines and gas engines.
on the tractor.
Among them, the gas tractor project was a complete failure. No one purchased the withdrawn product at all. People would rather continue to use bulky steam engine tractors than the troublesome and very unsafe gas engine tractors.
But their industrial gas machines were a great success!
It didn't take long, but it has already received orders for thousands of units, and Hangzhou Power Machinery Company has also launched a variety of improved models.
Because this thing is small in size and weight, and more importantly, has high thermal efficiency.
Nowadays, the thermal efficiency of Hangzhou Power Machinery Company's industrial gas generators can reach 18%, which is a quite terrifying number.
Its single-machine power has also increased from more than ten horsepower at the beginning to more than one hundred horsepower now.
This kind of gas machine is very suitable for many factories. Not only does it have lower fuel costs due to its high thermal efficiency, but more importantly, it is small in size, more stable in operation, and easier to maintain.
It will not be the same as a huge and heavy steam engine, not to mention the high fuel cost, and the maintenance is also more complicated.
In Lin Ziran's opinion, gas engines do not have much future. Although they will have a place in industry in the future, they are definitely not as big as gasoline engines and diesel engines.
Even a kerosene engine is useless in a short period of time. He is not engaged in aerospace these days, so what does he need a kerosene engine?
As for diesel engines, this thing is useful, but judging from the report, it is more difficult to develop than gasoline engines, and there are many defects that are difficult to solve, such as large vibrations and higher requirements for body manufacturing.
After all, this thing relies purely on high compression to allow the temperature to exceed the auto-ignition temperature of the fuel to burn and work.
This places higher requirements on the manufacturing of cylinders and many other parts.
From a purely technical perspective, diesel engines are more difficult than gasoline engines.
This is why gasoline engines have already begun prototype testing, while diesel engines don’t even have a prototype yet.
In the short term, the only internal combustion engine that can be put into practical use on a large scale is the gasoline engine.
The overall scientific and technological level of the Tang Dynasty, if compared to the nearly industrial countries on earth, is actually very unevenly developed.
In some subjects, especially theoretical subjects, the scientific level of the Tang Dynasty can even be said to have reached the level of the early twentieth century. Professor Wei Qingxin’s research on the theory of relativity has long been completed, and now quantum physics is almost the same.
Yes, but it's all theoretical research, and it's theoretical research done on the shoulders of the giant, the Holy Emperor Li Xuan.
For this reason, the arrogant Professor Wei Qingxin has been raising funds to conduct experiments in the past two years in order to find various evidences in the experiments to prove these theories and to find out the next direction for his research.
After all, knowing theory is not enough, you have to come up with practical things to prove it.
For this reason, the Department of Physics of the Royal Institute of Technology has spent a lot of money. There are complaints within the Department of Physics of the Royal Institute of Technology. But Wei Qingxin turned around and went directly to the Army to ask for funds. Those idiot generals of the Army
I don’t know what happened, but I was fooled for a while, and finally spent a large amount of money to let Wei Qingxin toss...
Various theoretical research represented by Wei Qingxin has gone far beyond that, but in other aspects, especially basic disciplines, manufacturing fields, etc., it lags far behind.
Especially the basic materials are lagging far behind.
Many theoretical studies in Datang could even reach the level of the early twentieth century, but manufacturing, especially basic materials, was at best the level of the mid-nineteenth century.
There was no other way. A genius in theoretical research had an idea and got started immediately.
As for materials, you have to fiddle with them slowly, and you need to constantly conduct various tests and selections to select the one that can be used from countless possibilities.
These all require time and huge experimental funds to be accumulated slowly, and there is no rush.
