Start with a blacksmith shop

Everyone in the live broadcast room also heard the huge roar from the engine.

That sound was continuous and not the usual sound of horse hooves.

[Dig groove, this sound is good! 】

[It’s very majestic, I like this sound. 】

[We witnessed the birth of a radial engine. 】

[Is the anchor planning to build a plane? The radial engine is out! 】

[This B upstairs must be new here. 】

······

The live broadcast room was already in a state of excitement, and the mood in the workshop was almost as high.

After increasing 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 difference between the data and what he got in the virtual laboratory.

After verifying it bit by bit, sometimes the throttle is pulled to the bottom, and sometimes it is released, letting it rotate at the lowest idle speed.

A power output line diagram gradually appeared on the computer. From the diagram alone, the power output is very smooth.

Keeping all the data on the computer in mind, he turned his attention to the engine again.

He saw the engine temperature displayed directly in front of his eyes.

Looking at the temperature of the engine casing at this moment, the displayed temperature is actually only 80 degrees.

If the car is installed at this temperature, the outer shell temperature will definitely be lower after running.

The analytical eye worked again at this time, and saw that the vibration value was very small, and at the lowest idle speed, the operation was very smooth.

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

Seeing the data from these experiments, he was so excited that he couldn't calm down at all.

Regarding the performance of the engine, after the actual car is built, the vibration of the engine may not be felt at all while driving, or even if it is felt, it will be slight.

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

After the engine had been running for half an hour, he cut off the power to the spark plug.

The spark plug no longer fires and the engine stops.

This time the test run has come to an end, and the engine will be inspected later.

Take a look at the oil condition, disassemble a cylinder and see how the cylinder wall is worn. After a series of inspections, the time has come to noon again.

After a morning of test runs, so far, the data obtained showed that the engine in front of them had fully met the established indicators.

The three people who had been working all morning sat on the ground around the engine in the middle.

"I've just been watching you test over there all morning. Why don't you tell us brothers how the engine is doing!"

Guo Shugui, a guy who broke his leg while playing with a car, finally couldn't help asking Li Zhenhua the question he was most concerned about.

He was sitting on the ground to rest. When he heard Guo Shugui's question, he put the water glass in his hand on the ground.

Come back to the live broadcast computer and bring the main camera in front of them.

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

You must be very confused in front of the live broadcast room!

Now I agree to say it. Judging from the current testing situation of this engine,

It fully meets the indicators I designed, including speed, horsepower, torque, case temperature, vibration amplitude, combustion ratio, etc., all of which are qualified.

The engine displacement of this machine is 450cc, and it can output a maximum of 71.9 horsepower, which is 0.9 horses higher than the indicator I designed.

Some friends may not know what 70 horsepower represents. I will give you a simple example:

Everyone knows about Ricky, but the engine power of this car is only 51.7 horsepower.

The one in front of us has more than 20 horsepower more than the Kou Kou.

Think about it, veterans, what a powerful motivation this will be. "

After saying this, he paused and turned to look at Guo Shugui,

At this moment, this comparison is as if it has never been seen on the market before, and it is almost lying on the engine.

"Guo Ba, don't get so close, or I'll burn your face!"

After reminding Guo Shugui, he turned his head again.

"Everyone must not learn from this. If you are not careful, you may be disfigured.

Next we are going to light this engine on fire and put it aside for the maximum working time test.

We will add a new set of shots to this test, please supervise and see how many hours this engine can continue to work.

In the afternoon, I plan to test the seven-cylinder model. The program is the same as the one I just tested.

If Tiezi feels bored, he can go out for a walk and see the young ladies.

If you meet someone who is more popular, you go first. After you finish, remember to tell me in the live broadcast room, and I will go and watch. "

After speaking, Li Zhenhua didn't care about what was going on in the live broadcast room, turned around and kicked the fat man next to him.

This fat man was exhausted this morning. He had been assisting Li Zhenhua in testing.

He did all the physical work, such as transporting oil and lifting things.

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

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

After the three of them finished doing this, they went out to eat something, and then continued testing the next engine when they came back.

After a few days of busy work, all the data in the engine test reached the design specifications.

There are also several pieces of data that cannot be tested over a period of time, so these can be ignored.

Anyway, the two engines are running in the workshop and data has been collected.

The originally quiet workshop now indeed has two extra days of noise-making machines.

You must know that the engine at this time was not equipped with a muffler. The pure original sound, no matter how quiet it was, was not much quieter.

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

But at this moment, he was annoyed by the noise, and he no longer had the excitement he felt when he heard the roar in the first place.

"Oh dig a trench, the sound is really noisy. It seems I have to get the muffler out first, otherwise I will go crazy due to this working environment."

He was once again the only one left in the workshop, while Liu Xiaodong and Guo Shugui went about their own business.

Li Zhenhua also laid out the materials used to make the exhaust pipe in front of him.

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

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

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

Everyone knows that the noise of this radial engine is relatively loud compared to ordinary motorcycles.

If the muffler is not fixed properly, the motorcycle will definitely not meet road standards.

In the end, it will inevitably become a street bombing tool for the ghost-fire boys. Of course, the ghost-fire boy cannot afford his car.

Manufacturing began, and the carbon fiber slowly changed its shape in his hands.
