Everyone in the live broadcast room also heard the huge roar of the engine,

The sound was continuous, not the usual sound of horses' hooves.

[Dig a groove, this sound is okay!] 】

[It's majestic, I like the sound.] 】

[We witnessed the birth of a radial engine. 】

[Is the anchor planning to build an airplane? ] The star engines are all out! 】

[This B upstairs must be new. 】

······

The pan has been fried in the live broadcast room, and the mood in the workshop is almost the same.

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

Looking at the data displayed above, he analyzed the data little by little, verifying what was the difference between the data and what he got in the virtual lab.

After a little bit of verification, sometimes he pulled the throttle all the way down, and sometimes he released the throttle to let him spin at the lowest idle.

A line diagram of power output gradually appeared on the computer, only from the picture, the power output is very stable,

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

I saw the temperature of the engine, which was directly displayed in front of his eyes,

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

If you put such a temperature in the car, the temperature of the shell will definitely be lower after running.

At this time, the eye of analysis made another contribution, only to see that the vibration value was very small, and the operation was very stable at the lowest idle speed.

Even at maximum throttle, the engine vibration value only rises slightly.

Seeing the data from these experiments, his heart was excited at the moment, and he couldn't calm down at all.

In terms of the performance of the engine, after the actual car is built, the vibration of the engine may not be felt at all during driving, and even if there is, it will be slightly felt.

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

When the engine was running for half an hour, he cut off the power supply to the spark plug to the engine.

The spark plug stopped igniting and the engine stopped.

Even if this test run is over, the engine will be inspected later.

Look at the oil situation, disassemble a cylinder to see how the cylinder wall wears, a series of checks, and the time is noon again.

After a morning of test running, for now, the data obtained shows that the engine in front of them has fully met the set indicators.

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

"It's been a morning just to see you test over there, and you can also talk to our brothers about how the engine is!"

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

He was originally 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.

Go back to the live computer and bring the main camera to them.

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

Presumably you in front of the live broadcast room are also very puzzled!

Now I agree to say that this engine is based on the current test situation,

It fully met the specifications I designed, and the speed, horsepower, torque, case temperature, jitter amplitude, and combustion ratio, etc., were all qualified.

This engine has a displacement of 450cc and can produce 71.9 hp, which is 0.9 hp higher than I designed it.

Some friends may not know what 70 horsepower represents, I will briefly say an example,

Ricky knows all the buckles, the horsepower of this car's engine is only 51.7 horsepower,

And the one in front of us, the horsepower is more than 20 horses greater than the buckle,

Think about it, old iron, what a powerful power this will be. ”

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

At this moment, this ratio is like never seeing the market, and even the engine is about to be on the ground.

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

After reminding Guo Shugui, he turned his head again.

"Don't learn it, if you're not careful, you may be disfigured.

The next thing we're going to do is set this engine on fire, set it aside, and test it for maximum working time.

We're going to be adding a new set of shots to this test, so please monitor it to see how many hours the engine will last.

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

If you feel bored, you can go out and take a look at the young lady,

If you encounter the top one, you rush first, and remember to tell me in the live broadcast room after rushing, and I will also go to watch. ”

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

This fat man was tired in the morning, and he had been assisting Li Zhenhua in the test.

What kind of carrying oil, carrying something, all these manual tasks are done by him.

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

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

The trio did this, went out to eat something, and then came back to move on to the next engine test.

After a busy few days, all the data in the engine tests reached the design indicators,

There are still a few items of data that can not be tested in a period of time, and these can be ignored.

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

The originally quiet workshop did have two more noise making machines at the moment.

You must know that the engine at this time is not equipped with a muffler, pure acoustic sound, even if the sound is small, it is not small.

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

But now he was so annoyed by the noise that he no longer had the excitement of hearing the roar.

"Oh dig groov, this sound is really noisy, it looks like I have to get the muffler out first, otherwise I'm going to have to go crazy with this work environment."

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

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

The most conspicuous thing I saw 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 is also chosen for the lightweight of the body.

The design of this muffler, he can be said to have put a lot of thought into it,

We all know that the noise of this star engine is relatively large compared to ordinary motorcycles.

If this muffler is not good, this motorcycle will definitely not meet the road standards.

In the end, it will inevitably become a street bombing tool for the ghost fire boys, of course, the ghost fire boy should not be able to afford his car.

began to be manufactured, and the carbon fiber slowly changed shape in his hands.
