Chapter 556: The Joy of Success (Fourth Watch)

I really wanted to ask them how they did it, but looking at the figure of all the people in the entire laboratory who were nervous and busy, Zhang Lan wisely gave up this idea: it is estimated that asking is also in vain, everyone is busy to death, and no one will definitely pay attention to the green onion.

The engineers involved in the test work are still busy remembering the data, the engine speed is still rising, the pointer of the engine's analog tachometer is still flying forward, and now it has reached an astonishing 15,000 rpm, the power output has reached 48 horsepower, all the information of the engine displayed on all the displays is normal, there is nothing wrong, even the strength of the engine body, there is no decline. At this point, it can already be said that the design of this engine is successful.

The entire lab was staring with bated breath at the data displayed on the screens of the monitors, as if there was some magic in the data displayed on the small screens.

The speed of the engine is still rising rapidly, and it has reached the theoretical maximum safe speed of 17,000 rpm per minute, at this time Zhang Lan looked at the power output display, and it has reached an astonishing 55 horsepower! At this time, the maximum fuel consumption of the engine displayed on the display next to the engine is only 3 liters. \\\ This power output has exceeded the engine power of Chery's small QQ car with an exhaust of 0.8 liters! The maximum output of that engine is only 51 horsepower, and to achieve this power, the instantaneous fuel consumption must reach more than 6 oils.

It is almost an impossible myth that a twin-cylinder 250-cc engine outperforms a three-cylinder 800-cc engine in terms of power output!

It's just that at this time, looking at the torque output graph, the torque output starts to decline when the engine speed reaches 16,000 rpm on the contrary.

This is normal, nothing to fuss about. This is the case with any engine, the engine torque output and power output are not the same, if you want to improve the power output, you just need to step on the accelerator, as the throttle increases, the power will naturally increase. But this is not entirely the case with the torque output, which is usually the largest in a range and exceeds this range. Even if you press the throttle harder, it will only increase the power output of the engine, but the torque output will continue to decrease. \\\\

Well, the good thing is that the torque drop curve of this ceramic engine is very gentle, not a sharp drop, which is much better than a traditional metal engine. Conventional metal engines drop their torque output at an almost 45-degree angle after the peak.

The maximum torque output of this engine is staggering: it can go from 6,000 rpm to 16,000 rpm, a full range of 10,000 rpm, which is beyond the reach of any internal combustion engine today – even a Formula 1 racing engine! Seeing that the engine was still running safely and smoothly after reaching the maximum safe speed designed, people who had held their breath and didn't even dare to breathe before the scene finally couldn't help but start cheering, and everyone understood very clearly what it meant: the engine designed by themselves has reached the theoretical level of the design. A product of epoch-making significance and real practical value. It was born from the hands of himself and others!

Hats on the engineers' heads, which were about the same as doctors' hats, were thrown all over the house, and masks were flying all over the room! Then he fell to the ground and was trampled around by countless pairs of feet. \\/\

"Don't be too happy just yet!" A voice interrupted the cheering crowd. Zhang Lan turned his head to look. It was no one else who said this. It was Xie Fei, the chief designer of this engine, who was also slightly happy on his face at the moment. But more of it was still tense seriousness, "Look carefully." We have not yet tested the data of the engine record, how long the engine can last in this condition, and after this test, we are happy after confirming that there is really no problem. ”

Xie Fei's words suddenly calmed down the cheering crowd present: yes, this is just reaching the highest safe speed, if you can hold on to this speed for more than half an hour without any problems with the engine, then it can show that the design of this engine is indeed safe and successful, and it is indeed a little early to be happy now.

Zhang Lan looked at the information displayed on all the monitors: Now the operating temperature of the engine has reached 1180 degrees Celsius, which is still 120 degrees Celsius away from the maximum working temperature of 130 degrees Celsius mentioned by Xie Fei Xie Da.

Zhang Lan paid attention to it, the indoor temperature is 25 degrees Celsius now, which should not be so high in normal times, that is, seventeen or eighteen degrees, but now that so many people have come in the laboratory, coupled with the heat of the continuous operation of the engine, it is normal for the indoor temperature to be higher than usual. \\

If the engine is installed in the car and runs outdoors, and there is oncoming cold air to dissipate heat from the engine, Zhang Lan naturally does not worry about the high working temperature of the engine, but under the condition that the indoor air is only supplied by central air conditioning, can the engine run safely for more than half an hour, and the working temperature of the engine will not exceed the maximum safe working temperature of 1300 degrees Celsius?

Time passed little by little, and everyone was staring at the monitors: twenty minutes later, the engine was still running smoothly, and the engine's data were still normal.

Due to the high speed of the engine, although the noise of the engine has been muffled by the specially designed muffler, it is still a little noisy compared to the sound that seems to be blowing in the ears at the beginning of the test.

But everyone in the laboratory didn't think the sound was noise, but closed their eyes as if they were enjoying the music and listened softly to the sound of the engine. \//\ Zhang Lan looked at a decibel meter next to him that displayed engine noise, and the engine noise displayed on it was 70 decibels at the moment.

This unintentional look really scared Zhang Lan: Generally speaking, when the car engine is running at high speed, its noise is between 80-100 decibels, which is still the noise level after a series of noise treatments such as sound insulation treatment in the engine compartment and the installation of high-efficiency silencers, etc., and this ceramic engine is only 7 decibels at such a high speed, without any noise isolation measures? In addition to being incredible, Zhang Lan really couldn't find a better adjective to describe the greatness of this ceramic engine designed by Xie Fei and Xie Da Engineers. ,

Perhaps, it is really only in the magical land of China, using the ancient and modern thing of ceramics, that such a miracle-like thing can be born?

At this moment, looking at the working temperature of the engine, it has risen compared to just now, and it has reached 1200 degrees Celsius, Zhang Lan is relieved: it has only risen by 20 degrees Celsius in 20 minutes, which is still in the case of almost no flow of indoor air, of course, such a situation cannot occur in the actual use process. It seems that the maximum safe operating temperature of 1300 degrees Celsius is wanted. The engine needs to reach higher revs.

The display next to the engine body strength also shows that the strength of the engine body is not much lower than under normal circumstances, and the strength of ceramics is not easy to decay at high temperatures.

In the blink of an eye, half an hour of engine test work has come to an end, the engine has been running smoothly at the theoretical maximum safe speed, without any problems, if the only change is that the working temperature of the engine has risen a little again, after half an hour, the working temperature has reached 1210 degrees Celsius.

Zhang Lan is not worried about this: in the current situation that the room does not move at all and simply relies on the almost non-flowing air in the room to provide cooling for the engine, the engine can reach this level of normal operation, so if the engine is installed in the car, there is an oncoming natural wind to provide cooling for the engine? Maybe the operating temperature of the engine can't even go up to 1100 degrees Celsius, right?

Everyone stared closely at the countdown counter in front of them that showed the working time of the engine at the highest safe speed, and finally, the countdown time counter jumped to zero, and the engine was still running normally there, and the data of the engine were completely within the normal range, and completely proved the success of their design, all the design engineers could no longer hold back their excitement this time, and everyone did not care about their own image in the jumping, laughing, crying, roaring, and in a daze. They crossed their chests and embraced each other excitedly, and they used all the ways to express their inner excitement.

At this moment, everyone is proud of their success!

No one thinks that their crazy behavior at the moment is a gaffe, Zhang Lan knows that for the arrival of this day, the employees of their entire special ceramics research and design company have put in too much effort, listened to too much gossip, and carried too much baggage, and now, they can finally use such an admirable achievement to give a resounding slap in the face to those who doubt themselves: they have proved with practical actions that the group has spared no effort to support themselves over the years, and has not been stingy with the huge investment of research funds. It's really worth it! I have also proved with practical actions that I am worthy of the company's huge annual investment in research funds and the high salary offered by the group!
