Ma Jianbin shouted in ecstasy: "All personnel, start recording data immediately." ”

"Test the rpm!"

"Test the wind speed!"

"Test the sound."

"Check the current output band with an electrical signal."

“……”

A group of professionals took all their professional tools and immediately went into action, surveying data around the frantically functioning internal combustion engine.

Ma Jianbin said to Han Xian, the other party with a heavy face: "Brother Han Xian, the most important part has to be completed by your electromagnetic institute."

Fang Hanxian sighed: "I don't need you to say it, I know." Alas, this spark plug is really a technical problem. It took two successive ignitions to succeed. And this is just a sample, if this problem is not solved after mass production, there will be a big problem. ”

"I have one last question that I need to confirm." Ma Jianbin frowned.

"You say."

"Can't we convert electric start to AC start?"

Fang Hanxian shook his head: "No." AC starting is simply not practical. Only when it works with a dry battery can it work continuously. This is because the spark plug needs to be lit several times per second. ”

Ma Jianbin sighed: "But its workflow is so short. But we passed 42 experiments, and we were only able to make this four-stroke gasoline engine work through electric ignition. But when the battery inside it runs out, it stops working. It would be nice if there was a way to keep it in battery life all the time and be able to work all the time. ”

Fang Hanxian also shook his head gloomily: "This is basically impossible. It is only possible to carry a large number of dry cell batteries, equipped with a voltage detection meter. Replace the battery when it's low and restart it...... There is no other way. Although this gasoline engine is more convenient and efficient than the steam engine. But the only drawback is that it burns not only oil, but also electricity. ”

"Is there really no way to make it work constantly?"

“……”

As he was talking, there was a sudden commotion in the field.

But I saw that the gasoline engine that was spinning at high speed suddenly shook a few times, and then the roar disappeared. The propeller began to slow down and then stopped spinning.

Onlookers were in an uproar:

"This ...... Why did this stop? ”

"It's only been more than ten minutes, why did it stop?"

"Go on, I haven't seen enough."

"I still have to keep an eye on it, why did it stop?"

"Is there something wrong?"

“……”

Ma Jianbin ignored everyone and hurriedly asked, "Is the data all recorded?" ”

"It's recorded, don't worry about Dean Ma."

"That's good."

“……”

At this time, the person from the Institute of Electromagnetism took a dry battery and walked to the internal combustion engine, opened a small box attached to the internal combustion engine, pulled out an identical battery from it, and replaced it with a new battery.

"Start!"

Someone pressed the red button. The internal combustion engine rattled a few times, then swirled again.

Because the machine had already been warmed up, this second start did not take too much time.

The onlookers couldn't help but be confused: "So, is this an electric motor?" ”

"So does it eat oil or electricity?"

"Why do I need to replace the battery?"

"Is it a hybrid of oil and electricity?"

"Yes, it should be a hybrid of oil and electricity."

"That pot of gasoline is already halfway through, so it must be oily. But the battery has also been replaced, so it is also electric. So...... It should be a double eater of oil and electricity. ”

"Well, that's a problem. If you want to use it, you need to have your fuel on hand as well as your batteries. ”

“……”

Fang Hanxian listened to everyone's discussions, was a little congested, sighed and said: "Alas, my Institute of Electromagnetism will definitely research a battery with longer endurance and greater milliampere power as soon as possible." Now a battery can keep the internal combustion engine working......"

The data clerk next to him immediately shouted: "Twenty-four minutes." ”

"Yes. Now a battery is capable of keeping an internal combustion engine running for twenty-four minutes. But in the future, we will definitely let the internal combustion engine work continuously for more than an hour. ”

I heard Fang Hanxian say this.

Some layman onlookers were discussing:

"Twenty minutes is not bad. I bought a steam car from the Xingtu Group, and I had to stop and take a breath after running for more than 40 minutes. ”

"Who said that? The steam car I bought didn't need to be gasped. ”

"You didn't read the instructions carefully, did you? Generally, running for an hour and stopping to let it catch its breath can effectively prolong its life. If you keep running, you keep running. If you don't pay attention to maintenance, its life will be broken and it will age quickly. ”

"Oh, that's what you mean. Hehe, it's okay, I'll buy another one if it breaks down, what's the matter for a day. ”

"Oh, cow pie, oh, local tyrant."

"Hehehe."

Everyone was talking, but they digressed when they chatted. And this phenomenon of talking off topic is a phenomenon of 'not paying attention' in psychology.

Maybe everyone's psychological subconscious already feels that the fuel engine is chicken, right? Or the steam engine is solid and resistant to beating.

Woolu can run all the time, all you need to do is burn coal. Run into the deserted wild forest, pick up some firewood and feed it in, and it can run. The people on the grassland ran and ran without coal, picked up two pieces of horse manure and threw them in, and they could still run!

This is the steam engine, the leather is solid, resistant to beating, and not picky eaters.

And although everyone saw the obviously more advanced and scientific internal combustion engine, they suddenly lost some interest. It's powerful, but what's the use?

In more than twenty minutes, it was over in a shuttle. Not long-lasting.

And you have to burn oil, this gasoline is not easy to buy, and you can't burn anything else.

Even if it's burning oil, it's actually fine. It's hard for the rich.

But the problem is that in addition to burning oil, it also burns electricity, which is a little unbearable. It's too pretentious......

At this moment, the village chief of Dafengtai Village came over with his hands in his sleeves and said in a puzzled voice: "Dean Fang." I like to ask if I don't understand, don't you mind. I mean, this thing is already spinning. Doesn't it generate energy when it rotates? As you often say, energy doesn't come out of nowhere, and it doesn't disappear out of nowhere...... Can't you just let it charge while it works? ”

“……”

Hiss –

As soon as these words came out, the entire Kyushu Academy of Sciences was instantly silent.

Everyone gasped and looked at this old man dressed in an old hat, with a few piles of rent money he had just collected from the vendor in his arms, and his face was full of vicissitudes.

The village chief of Dafengtai shouted: "What? Am I saying something wrong? ”

Fang Hanxian and Ma Jianbin glanced at each other. Collective petrochemical.

It's really stupid. Stupid.

Why didn't we think of it?

It's really an insider, and I was woken up by a layman's words. If you are really in the game, you can't see the situation clearly.

That's right, since the dry battery will be consumed. But at the same time...... The reason why the battery can store electricity is because it has the characteristic of being able to charge. And the simplest principle of power generation is triboelectric power.

As soon as the engine works, doesn't that generate power? With this raw power, a generator is equipped on the engine.

Output current while inputting current.

Doesn't this completely solve the problem of changing the battery every 20 minutes?

Ah!

How stupid!

Fang Hanxian and Ma Jianbin smiled helplessly. Speechless......

ps: Today my sister's child has a full moon. I, the one who was upgraded to be an uncle, ran up and down all day...... The update is late, so I ask for your understanding. Let's start with two shifts today. There's also a table outside to entertain and pour wine......
