Li Rujin discussed with the left-behind personnel of the R&D team It seems that there are two reasons for the engine crankshaft problem, one is the accuracy problem, when the engine is running at high speed, even a little flaw in the crankshaft may cause fatal consequences. The engine is damaged at least www.biquge.info worst, and it may cause the engine to explode, which is a serious problem.

This problem cannot be solved unilaterally by the engine R&D team alone, maybe the R&D team can solve it by hand grinding, but when it comes to actual production, do you still have to rely on hand grinding? This is definitely not going to work.

This point should be solved by the R&D team and the machine tool R&D team, Li Rujin wrote it down and said hello to Sun Dahai later.

Another reason, it is much more difficult, is the material problem, the greater the horsepower of the engine, the higher the requirements for the materials used to manufacture the engine, especially the core components of the crankshaft, which are controlled by the highest requirements and the strictest standards.

In this way, the crankshaft material used in the 500 horsepower engine is not qualified, and the new material is not satisfactory, and it is okay to use it in the laboratory, if it is really to be used on the battlefield, in the face of complex and changeable geographical environment, climate, maybe, there are many problems.

At this point, Li Rujin is a little helpless, materials science can be said to be the weakest discipline in the Dawen Empire, this is not a problem that Li Rujin can solve by providing some new materials.

Materials science can be said to be vast like a sea of smoke, but also throughout the bits and pieces of our life, clothing, food, housing and transportation, you can see its figure, what materials are suitable for what, there are materials science in it.

Similarly, materials science is also a huge cost and requires a large amount of capital investment, which can be said to be a black hole in the black hole of funds, and the materials science of the Dawen Empire is completely in its infancy, and it is still difficult to provide qualified materials.

Since it is impossible to get a breakthrough from the material, then it is a good way to solve the problem from the way, such as the supercharged engine, which is a good way to solve the current dilemma. There are two ways to supercharge an engine, one is mechanical and the other is turbocharging. Both methods have their own advantages and disadvantages.

As soon as Li Rujin's idea was put forward, the eyes of the research team lit up, they were all experts in engines, and they were technically thorough, and they immediately understood what Li Rujin meant.

The breakthrough of the engine was found, and the left-behind personnel of the entire R&D team were in high spirits and were in a hurry to put into work, but they were persuaded back by Li Rujin, seeing that the New Year was coming, and not because of this incident, it would lead to an unintentional New Year.

Li Rujin left the engine R&D center and walked towards Sun Dahai's office. As a result, Sun Dahai was no longer in the office, and he didn't know where to go, Li Rujin had to go home, planning to sleep, these days, he was not busy, he was tired, this kind of tiredness is not the kind of tiredness physically, but the kind of fatigue in the spirit.

The emperor's and a cabinet elder were in charge of the disaster area in the south, and they took helicopters to visit the people in the disaster area.

Other elders were in charge of other major cities, going to appease the unemployed workers, etc., and bringing condolences were also very practical, rice, flour, grain and oil, or 200 yuan for the festival. Of course, there are a lot of reporters accompanying him, otherwise how can he hype it?

Soon, the two newspapers of the empire began to report on this matter at great lengths on their respective front pages, and it seems that hype is the nature of media people, and they don't even need Li Rujin's reminder to stir up this matter, and the entire empire is known to almost the whole people.

Of course, the effect is also very good, especially after an enthusiastic speech by the emperor, which reached the highest point, and this collective action of the top level of the empire was unanimously praised and praised by the whole empire!

With tears in their eyes, the victims in the south thanked the workers for their selfless dedication, and repeatedly said that they would build their homes well.

The workers were also proud that they had made so many contributions to the victims of the disaster in the south, even if they were wronged, it was worth it. Coupled with the fact that the cabinet members fanned the flames on the sidelines and said good things, the whole empire suddenly became harmonious.

The victims were encouraged by the emperor to become self-reliant and self-reliant, and carried out self-rescue actions after the disaster.

The unemployed workers also laid down their burdens and formed mutual assistance groups to fend for themselves and not cause trouble to the empire.

At this time, a song quietly spread in the land of the empire, whether it was the disaster area in the south or the land in the north, the whole world was singing this tune is a bit strange, but the lyrics are extremely inspirational.

This song is called "Start Again", and needless to say, this is another masterpiece of Li Rujin.

The emperor and the cabinet took action, and the bigwigs of the military department could not be idle, and they also began to go down to the grassroots level, to the company, to the border passes, to carry out condolence activities, and for a time the entire army system of the Dawen Empire took action one after another, and participated in the post-disaster reconstruction work in the disaster area, with high morale, active work, and struggle in the front line of post-disaster reconstruction.

The garrisons in other places also said that for the safety of the Dawen Empire and the happy life of the people of the empire, they would rather throw their heads and spill their blood, and make contributions and open up territories for the sake of the empire.

The collective action and collective appearance of the top level of the empire this time have caused an unexpectedly good effect, and the effect is simply amazing, and the whole empire has worked together to share weal and woe, which can be said to have successfully mobilized the enthusiasm of the entire empire, and the whole country seems to have taken a strong pill, bursting out with infinite vitality and vigor.

The high-level officials of the empire who had been walking around outside for a long time finally returned to the imperial capital collectively on the twenty-eighth day of the Lunar New Year.

The empire has such hard-working, kind, and energetic people, why worry that the Dawen Empire will not rise.

Is there a soldier in the empire who is so loyal and can give everything, even his life, for the empire, still worry about the safety of the empire? Are you still worried that the empire will not be revived?

The train runs fast, it all depends on the headband, as long as the Dawen Empire can work together to get out of the predicament and recast the glory, it will not be a matter of time.

The sluggish atmosphere of the entire empire underwent a great reversal because of a plan by Li Rujin, and the empire came out of its pain, regained its strength, carried on the past, and forged new glories.

On the twenty-ninth day of the Lunar New Year, most of the empire has entered a state of semi-vacation, and those who can go back early have slipped back to their homes early, busy with the New Year, leaving only two or three kittens in each department.

On the streets, naughty children have already set off firecrackers, and the sound of "crackling" firecrackers resounded in the streets and alleys of the imperial capital. The helpless adult looked at the child's happy smile, and what could he say, smiled tolerantly, and walked away, it was about to be the New Year.

Li Rujin's family started to be busy early in the New Year, and at the beginning, I thought that Li Rujin would not be able to come back for the New Year, but Li Rujin gave the family an unexpected surprise, this kid came back because he was homesick.

That's not even a big preparation! Chicken, fish, meat and eggs, delicacies from the mountains and seas, that's not a hard work!
