The researchers were on vacation, and Qiu Feng couldn't put it down stroking the prototype he designed and built. Because the heat generated by burning fuel in the cylinder was still there, the engine body was still a little hot, but Qiu Feng was a little indifferent.

It took eight or nine weeks to finally reach this point, and Qiu Feng was very satisfied. Although this engine still has a long way to go before it can be commercially used in large quantities and power countless mechanized equipment.

Qiu Feng was intoxicated in the laboratory for about half an hour, and was suddenly shocked because the cute female college student was still there.

"Hey, why haven't you gone home for a vacation? I've already given you a vacation," Qiu Feng said.

The cute female college student said, "Master Star Master, Master Principal, I am Chen Lina, a sophomore majoring in mechanical automation in the School of Mechanical Engineering of Qi Yao University. This time I asked my teacher for an opportunity to observe, but I have many questions.

I can’t even understand it, I hope you can explain it to me, I don’t need a holiday.”

Qiu Feng suddenly felt a little embarrassed, but then he thought about it, these are the future of the Seven Demon Stars. Since he had the opportunity, and he also had the desire to express and brag, he waved to the female college student Chen Lina and said, "Come here

Come on, let me explain to you the principle of this engine."

Taking Chen Lina with him, Qiu Feng walked to the iron box, pointed to the iron box, and said, "Classmate Chen, look at this. This thing is called fuel. It is a kind of fuel that is processed from crude oil extracted from the oil mines in the mining area.

, power. The application of this energy can reduce the scale and raw material application of steam engines.

A steam engine is mainly composed of a cylinder, a base, a piston, a crank connecting rod mechanism, a slide valve steam distribution mechanism, a speed regulating mechanism and a flywheel. The cylinder and the base are stationary parts. In a steam boiler, water boils into steam through the combustion process.

The steam is sent to the cylinder through the pipe. The valve controls the time when the steam reaches the cylinder, enters the slide valve chamber through the main steam valve and the throttle valve, and is controlled by the slide valve to alternately enter the left or right side of the cylinder, pushing the piston to move and generate kinetic energy.

My principle is similar, but it can realize the replacement of materials, and can achieve more kinetic energy, and can achieve the mechanical power required for greater kinetic energy."

Chen Lina took out a pen and paper and wrote it down as hard as she could. "It's equivalent to a change in energy. There is no need for a water vapor generating device like a steam engine. But it seems that refining fuel is not very easy. Engines like ours

The scope of application should not be broad.”

Qiu Feng did not answer Chen Lina's question about market application prospects, but took her with him and continued to point to the small hose and said, "This is an oil pipe. In fact, there is an air intake device in the engine, but it is designed to be hidden.

So easy to see.

The fuel enters the cylinder through the oil pipe, and burns to produce hot gas, which drives the piston to move up and down. The crankshaft is connected to the pulley of the engine. The piston drives the crankshaft to move, which is equivalent to pulling the pulley to rotate. The rotation of the pulley drives the pulley of the gearbox through the belt.

Create a dynamic.

The pull ring of the gearbox is the key to controlling the meshing of the gear of the gearbox pulley and the gear set. However, the radius of the gears of the gear set is not exactly the same. As long as it changes, it will change the final output kinetic energy.

At present, the sledgehammer has no practical significance. It only represents the output of kinetic energy. In the future, it can be connected to any mechanical equipment that requires kinetic energy, even the mixing, extraction, and bottling machines of the Qiu Pharmaceutical Factory you visited.

Replace it with this kind of engine for power."

Chen Lina was already trying her best to remember, but she still asked, "Master Star Lord, the working principle of this engine is actually similar to that of a steam engine. Although it is somewhat advanced, the cost is higher, so why not

What’s the point of carrying out such reforms?”

Qiu Feng rolled his eyes and said, "This still needs further optimization, but this principle is very important. If this thing can be improved to the point where it can be mass-produced for all machines and equipment and all systems that require power, then for the entire Seven Demons Star

In terms of industrial development, it is definitely a revolutionary improvement.

You college students need to face the long-term development of Seven Demon Stars in the future to expand your knowledge and conduct necessary research.

Not only do we need to know what is happening, we also need to know why it is happening.”

Chen Lina nodded as if she understood, and asked again, "Master Star Master, can you tell me your improvement direction? If it involves technical confidentiality, I won't blame you if you don't tell me."

Qiu Feng said, "First of all, the cooling problem of the cylinder needs to be solved. We just tested the machine for three hours, and the temperature of the cylinder has become unbearable. Although we have considered heat-resistant materials when manufacturing the cylinder, we are afraid that at this speed

If it continues to develop, it will be able to work continuously for five hours at most.

In a large-scale mechanized production process, continuous transportation for five hours is definitely not enough.

Secondly, there is the matter of piston lubricating oil. On the one hand, lubricating oil can improve the air tightness, and on the other hand, it can also reduce the wear rate of the piston and cylinder wall.

Thirdly, it is the design of the gearbox and shift lever. Currently I have only designed the third gear, but the fifth gear should also be possible. With more gears, we will have more options for trade-offs and combinations in terms of frequency and power.

Finally, it is about how the converted energy can be used. The current sledgehammer is driven by a crankshaft to ensure that the sledgehammer continues to hammer up and down. In the future, other application scenarios must be considered.

Originally, if there was no need to control the efficiency of power output, then there would be no need for gearbox design, but considering future application scenarios, gearbox considerations are still needed.”

Chen Lina nodded as if she understood. She had already recorded everything in her notebook, and then said, "Principal, what you said makes sense, and the design of the gearbox is really surprising. I will follow my instructions."

The teacher has visited many machines, but this is the first time he has seen this kind of design.

Can you invite you to our school to give a lecture on the design of this gearbox to my classmates? You are our honorary principal and have never taught us a class. If you agree, I will go back and arrange your lecture time. If

If you don't agree, then I will go back to my teacher to invite you. I am not inviting you for myself, but for my classmates and classmates."
