The National Power Laboratory in Milan is one of the three largest laboratories in Italy and the main research institute for power system research.

It can be said that in terms of power research, it is the first existence in Italy, even if the navy's ship power research encounters problems, it needs the help of the Milan power laboratory.

Of course, the National Power Laboratory in Milan is also huge, with 3 categories and 17 sub-categories, with a total of more than 800 researchers. Of course, in addition to the researchers, the National Power Laboratory also has its own supporting plant, which is responsible for the manufacture of various equipment parts and components required for the experiment.

Such a well-equipped laboratory is bound to cost a lot. Over the years, the Milan laboratory has spent hundreds of millions of dollars, and of course it has produced a lot, but in general, it is still a loss, with a loss of tens of millions every year. Especially in the past two years, the emergence of various new materials and equipment has made the laboratory's losses even more serious, with a loss of more than 15 million lire last year alone.

Of course, such an arrogant style naturally requires big financiers to withstand it, and the biggest financiers behind the Milan laboratory are the Savoy family. And the Savoy family has gained a lot over the years, so this year is more than 10 million lira, and it can withstand it for the time being, as for the future, who knows.

Of course, such a rich power laboratory naturally needs to recruit a group of valuable scientists, and Rudolf Diesel is on the list of those who are included.

Speaking of which, Diesel has a long history with Italy, and he had set up his own laboratory in Germany to study compression-ignition engines. Of course, research is also difficult, especially when Diesel is used as fuel.

The structural strength of compression-ignition engines is always a challenge. During one experiment, parts on the cylinder scattered like fragments of a cannonball, almost causing casualties. The experiment did not go well, Diesel gradually ran out of funds, and the laboratory seemed to be unable to continue.

At this time, an important sponsor offered him to go to Italy for experiments, and the remuneration was also very rich. In the face of the favorable conditions in the predicament, Diesel had no choice but to accept it.

When he arrived at the Milan laboratory, he realized that it was impossible to work behind closed doors. Doing research and development alone at home is not an opponent of joint research and development by multiple people at all. A lot of questions that bother you have answers here.

Therefore, Diesel also extinguished the idea of making a windfall with this, but had a strong heart for scientific research, and wanted to produce practical results for the diesel internal combustion engine he designed.

And today, a new experiment has begun. Diesel once again came to the test site with his newly designed four-stroke diesel engine.

"Buck, how's the check-up?"

Diesel asked about the assistant that the laboratory had assigned to him, although Buck was the assistant assigned to him by the laboratory, but Diesel was very satisfied with his assistant in the past two years, and he could provide him with great help in terms of knowledge, hands-on ability, and work.

"I've checked it twice, I checked it myself just now and there is no problem."

Assistant Barker's answer did not put Diesel at ease. "Buck, you said there wouldn't be any problems this time, right?"

Don't blame Diesel for asking, he has conducted more than 20 tests at the test site of the National Power Laboratory alone. However, this diesel internal combustion engine has always had problems, either the internal combustion engine is damaged due to poor materials, or the sealing problem leads to serious power loss.

Dealing with these problems has almost made Diesel's spirit almost decline, so he doesn't want to slowly find and improve after problems arise, and unsuccessfully change the way of thinking to continue to improve.

"Two, can I get started?"

The staff of the test site asked the two of them.

As for the test site staff, this is also due to the fact that the technicians are too valuable and the power machines they develop can be dangerous. In order to protect those valuable scientific researchers, the work of the experiment is done by others. This is a system enforced by the laboratory in the case of a tragedy involving the loss of seven researchers, one of whom was still a tech giant.

"Get started...... Don't wait...... Let's get started. ”

Faced with the direct eyes of the staff at the test site, Diesel was finally defeated.

So in the eyes of expectation, the staff started the diesel engine. A deafening roar sounded, and the four-stroke diesel internal combustion engine was constantly reciprocating. The indicator driven by the connecting rod kept rotating, and it didn't look like anything was going on.

"Professor, it seems that we have been very successful in the early stage."

Assistant Buck looked at the rumbling diesel engine and commented to Diesel on the side.

"It does look better than the previous ones, but we can't take it lightly and hopefully this machine will pass the test."

Experiments are actually boring, and dynamic tests like this one are even more boring, where the machine is running non-stop, and the staff needs to review the records every once in a while, and then hand over the records to the researchers who are waiting.

After taking the record book from the staff, the two looked at it.

"Speed: 900-1200r/min, average effective pressure: 2.0-3.2MPa, average piston speed 8.1m/s, plus torque...... Fuel consumption rate ......"

After the two talked for a while, they didn't see any problems, what else can they do now, continue to wait.

The boring experiment lasted for a day, and the two of them stayed here most of the time except for eating.

It wasn't until after the sun went down that the staff, who had also been tired all day, stopped the experiment.

"Professor Diesel Diesel doesn't seem to have any problems, after almost a day of work, we checked and found nothing. I believe that tomorrow's trial will continue. ”

The staff's words made Diesel feel a little confused, and the compression-ignition engine developed over the years finally saw the light of day.

Although the machine has only passed the first day, listening to the staff, if there is no accident in the next two days, it should not be a problem.

"Thank you...... Thank you...... Thank you Buck. ”

At this time, Diesel was very excited, and his wish for all these years was finally fulfilled.

"Professor, you deserve it."

The assistant's words made Diesel delighted.

"But without your help, I definitely wouldn't be able to do it now, and I still have to thank you Buck."

For the next two days, Diesel stayed at the test site and watched the diesel internal combustion engine he had developed run in operation. The results are also gratifying, and this four-stroke diesel internal combustion engine works well. Of course, its high horsepower and the use of waste oil that can only be used for heating, diesel as the power fuel, is naturally very eye-catching.

Of course, as Carlo, who has always followed Diesel's progress, of course, also knows about the advent of practical diesel engines.
