Everyone in the live broadcast room also heard the loud roar of the engine.

That sound is continuous, not the sound of horse hooves I used to hear.

【Digging a trench, this sound is OK!】

【It's very majestic, I like this sound.】

[We witnessed the birth of a star engine.]

[Is the anchor planning to build an airplane? All the star engines have been made!]

【This b on the upper floor is definitely new.】

······

The live broadcast room was already in full swing, and the workshop was in almost the same mood.

After adding the accelerator, Li Zhenhua calmed down and returned to the computer where the data was displayed.

Looking at the data displayed above, he analyzed the data bit by bit and verified the data. What is the difference between what he got in the virtual laboratory?

After verifying it little by little, sometimes pulling the accelerator to the bottom, sometimes loosening the accelerator, allowing him to rotate at the lowest idle speed.

A linear diagram of power output also gradually appeared on the computer. Judging from the diagram alone, the power output is very stable.

He kept all the data on the computer in his heart, and then he turned his attention to the engine.

I saw that the temperature of the engine was directly displayed in front of him.

Looking at the temperature of the engine case at this moment, the temperature displayed was only 80 degrees.

With such a temperature on the car, the housing temperature will definitely be lower after running, and air cooling can completely meet the engine cooling problem.

The Eye of Analysis made another contribution at this time, and the vibration value was very small, and it was running very smoothly at the lowest idle speed.

Even if the maximum throttle is added, the engine vibration value will only increase slightly.

Seeing the data produced by these experiments, he was excited and couldn't calm down at all.

With this performance of the engine, after the actual car was built, the vibration of the engine may not be felt at all while driving, and even if there is, it will feel slightly.

This vibration is much smoother than the three-cylinder Junqi, which is claimed to be able to enter the desert, and there is no need to open the nacelle.

After waiting for the engine to run for half an hour, he cut off the power of the spark plug.

The spark plug is not igniting, so the engine stops.

Even if this test run comes to an end, the engine will be inspected later.

Check the oil condition, take apart one cylinder and see how the cylinder wall is worn. After a series of inspections, the time has come again at noon.

After a morning of test run, as far as the data is concerned, the engine they are placed in front of them has completely met the set indicators.

The three of them worked all morning and sat on the ground around the engine in the middle.

"One morning, just seeing you testing there, you can tell us brothers how the engine is!"

Guo Shugui, a guy who broke his legs when playing with a car, finally couldn't help but ask Li Zhenhua the question he was most concerned about.

He was sitting on the ground to rest, but when he heard Guo Shugui’s question, he put the water cup in his hand on the ground.

Come back to the live broadcast computer and take the main shot in front of them.

"Friends in the live broadcast room, everyone heard what my brother had just asked,

I believe you are also puzzled in front of the live broadcast room!

Now I agree to tell you, this engine is based on the current test situation.

It fully meets the indicators I designed, such as speed, horsepower, torque, housing temperature, jitter amplitude, combustion ratio, etc., all of which are qualified.

, can output up to 71.9 horsepower, which is 0.9 horsepower higher than the indicator I designed.

Some friends may not know what 70 horsepower represents, so I will briefly give an example.

Ricky QQ knows that the engine of this car is only 51.7 horsepower.

And the horsepower in front of us is more than twenty horsepower than QQ.

Think about it, old men, how powerful this will be."

Speaking of this, he paused, turned to look at Guo Shugui,

At this moment, this comparison seems like I have never seen the market before, and it is almost on the engine.

"Guanba, don't get so close, be careful to burn your face!"

After reminding Guo Shugui, he turned his head again.

"Don't learn, you can be disfigured if you accidentally

Next we will light this engine and set it aside for the maximum working time test.

We will add a new set of lenses in this test. Please supervise and see how many hours this engine can last.

In the afternoon, I planned to test the seven-cylinder model, just like the program I just tested.

Iron Zi who feels bored can go out and see the young lady.

When you meet someone who is more powerful, you can rush first. After rushing, remember to tell me in the live broadcast room and I will go and watch it too."

After saying that, Li Zhenhua didn't care about the dynamics in the live broadcast room, and turned around and kicked the fat man next to him.

This fat man was exhausted in the morning. He has been assisting Li Zhenhua in the test.

What are he doing to carry oil or carry something?

"Fatty, get up, let's push the engine aside together and let him go through the test of time."

Liu Xiaodong reluctantly got up from the ground, and Guo Shugui was also busy moving around. The three of them pushed the engine under the new lens and ignited the engine.

After the three of them finished these, they went out to eat something, and after they came back, they continued to test the next engine.

After several days of busyness, all the data in the engine tests met the design indicators.

There are still several data that cannot be tested in a while, so these can be ignored.

Anyway, two engines are running in the workshop and data is being collected.

The originally quiet workshop did have two more days of noise manufacturing machine at this moment.

You should know that the engine at this time did not have a muffler. The pure original sound is not much smaller than that.

Listening to these sounds, according to Li Zhenhua's plan, the following work should be to weld the frame, but it was interrupted by the noise.

But at this moment he was so tired of the noise that he was no longer excited to hear the roar.

"Oh, digging the trough, this sound is really noisy. It seems that I have to get the silencer out first, otherwise I will have to go crazy with this working environment."

Once again, he was the only one left in the workshop, and Liu Xiaodong and Guo Shugui went to work on their own affairs.

Li Zhenhua also put the materials used to make the exhaust cylinder in front of him.

The most conspicuous one was a large roll of thermally conductive carbon fiber and a bottle of curing agent.

That's right, the main raw material of the exhaust pipe he chose this time is carbon fiber, which was also chosen for the lightweight body.

He has put a lot of thought into the design of this muffler.

Everyone knows that the noise of this star engine is relatively high compared to ordinary motorcycles.

If the muffler is not done well, the motorcycle will definitely not meet the on-road standards.

In the end, it inevitably turned into a street-blowing tool for the Ghost Fire boys. Of course, the Ghost Fire boys probably couldn't afford his car.
Chapter completed!
