"It's so cool. This speed is much more fun than riding a bicycle!"
After playing for half an hour, Zhu Houzhao got out of the car with satisfaction. He wanted to drive it himself, but Liu Jin and others stopped him.
His status is too noble, so we must not let anything happen to him, otherwise everyone's heads will not be saved.
"Of course, the car is driven by an internal combustion engine. There is no need to step on it at all. People can easily control the direction and accelerator. If you want to go faster, put more oil in it. If you want to go slower, just put more oil in it.
Put less gas, if you want to turn left, go left, if you want to go right, go right, it’s very simple and easy.”
When Lu Qing heard this, he said proudly.
"Not bad"
"However, I feel there is still a lot of room for improvement."
"For example, this control direction, it is very good to use this to control the direction of the bicycle, but for the car, because it is driven by an internal combustion engine, its horsepower is very large, I think it is still very inconvenient to use this kind of control, and there are also
Very risky.”
"I think it might be better to switch to a circular control."
Zhu Houzhao nodded repeatedly, then thought for a while and touched his chin and said.
"What His Highness said makes sense. We are also thinking about this issue. Because it involves the drive of the front two wheels, we also designed a special drive mechanism that uses multi-tooth gears for coupling control. So far, the effect is
It’s not very good yet, we are going to use separate control next, and using a disc-type control direction is indeed better.”
When Huang Zhiyuan heard this, he thought about it and nodded.
"Haha, right, I also study machinery, so I know a little bit about it."
"And your device for controlling the throttle. In my opinion, it can be placed where your feet are and you can step on it with your feet. If you step on it, you can increase the fuel delivery. If you release it, you can reduce the fuel delivery. In this way, you can control the power of the internal combustion engine.
, it seems that if you want it to go faster, you press the accelerator, and if you want to slow down, you release it.”
"In addition, I think you need to add more deceleration and shock-absorbing devices. This deceleration is for safety. If the speed cannot be reduced quickly, wouldn't something happen if there is an emergency?"
"Especially if this car speeds up and hits someone, big trouble will happen."
Zhu Houzhao nodded proudly, then pointed to the accelerator lever on the car and said: "It is more convenient to control the accelerator with your feet, and it also allows your hands to be free to concentrate on controlling the direction."
"This shock absorption is the most necessary. I just sat on it and my buttocks were numb from the shock. In my opinion, adding a layer of cushion to this wooden chair will make it more comfortable."
"Your Highness is wise, we have been thinking about these issues, especially the throttle lever, which has to control both direction and control. It is very inconvenient and even more dangerous."
"As for the deceleration device, we use two aspects to decelerate. One is to control the throttle and reduce the oil input, which will naturally reduce the power and speed. The other is to install a friction deceleration valve on the wheel, which is similar to riding a bicycle.
That kind of thing.”
After Lu Qing heard this, he couldn't help but his eyes lit up.
I have long heard that Zhu Houzhao is a genius and a master in mechanical research. Just taking a look and experiencing it, he immediately put forward so many suggestions, many of which no one had thought of for a long time.
For example, no one could think of a good way to control the throttle lever. Unexpectedly, Zhu Houzhao suddenly thought of pressing it with his foot.
"The braking system can also be stepped on with your feet, and it is placed under your feet."
Zhu Houzhao emphasized again.
"Yes, this is indeed a good way, so that you can control the car with both hands and feet."
Lu Qing also quickly asked someone to write it down in detail.
"Also, this should be the fuel tank. It's not good to put it in the front. It takes up space and is unsafe. In my opinion, it can be placed at the bottom of the car. In this case, there will be a lot of space in the front.
Together, we can make a good plan for this internal combustion engine."
"The placement, control system, etc. can all be redesigned."
"Well, it's best to get a cover to cover all of this, so it looks much more comfortable."
Zhu Houzhao touched his chin, looked at the internal combustion engine and fuel tank in front and said.
"Write it down, write it down, write it all down."
Ren Siheng also quickly asked someone to write it down, and then study it in detail and make continuous improvements after returning home.
"In my opinion, we need to add a cover to this car, just like the carriage. Otherwise, what can we do if it's windy and rainy? Isn't it possible to get wet in the rain?"
Liu Jin thought for a while and then said that he was going to tell some things about the design of later generations of cars, so that he could speed up the manufacturing of cars. Otherwise, if he changes slowly, he still doesn't know what to change.
I am planning to drive around and go for a walk in the future.
Gu Da
"But if a cover is added, the front will still be exposed to wind and rain, right?"
Duan Hai thought for a while and said.
"We can use glass. Wouldn't it be enough to make a windshield?"
Liu Jin said again.
"This is indeed possible."
Lu Qing nodded repeatedly when he heard this.
“In addition, you can add two mirrors on both sides of the front of the car, called rearview mirrors, so that you can see what’s going on behind you. If there are more cars in the future, you can use this rearview mirror to see what’s going on behind you.
This way accidents can be prevented.”
Liu Jin pointed to the two sides of the front of the car and continued.
"And this tire, a water-blocking and mud-fender guard should be added to the tire, so that mud and water will not be brought into the car or to the important engine due to the rotation of the car tire."
"The design of this seat needs to be improved. It needs to be more comfortable and has a backrest."
"Can the exhaust be placed behind the rear of the car and be exhausted through the bottom of the car, so that the black smoke that is sometimes emitted will not choke you or block the front sight?"
"Yeah, why didn't we think of it?"
After hearing Liu Jin's words, Lu Qing, Huang Zhiyuan, Ren Siheng and others all opened their eyes slightly, and couldn't help but suddenly realized that such a design could be possible.
"In addition, it is best to get a bell or something like a bicycle, so that we can remind each other in case of emergency."
"In terms of safety design, there should be more designs, such as how to prevent the car from sliding down if it is parked on a slope, how to ensure safety when starting on a slope, etc."
"There is also this startup method. In my opinion, it is better to start it directly from the front, saving two people to operate it, or quickly get a container that can store electricity, so that there is no need to temporarily pass
The hand crank generates electricity."
Liu Jin also kept making suggestions one after another, which made Zhu Houzhao, Ren Siheng, Huang Zhiyuan, Lu Qing and others on the side widen their eyes.
How come Liu Jin knows everything?
Even the car can come up with a bunch of suggestions, and it feels like you have seen a truly perfect car. There are many things that even the inventors and designers of these cars could not have thought of.
"Write it down, write it down!"
Ren Siheng and Duan Hai also quickly asked people to write them down.
It was not because of Liu Jin's identity, but because the suggestions Liu Jin made were things they had never thought of and were truly useful suggestions.
It feels like Liu Jin understands cars better than mechanics like them, and he also understands cars in general.
"After listening to the suggestions of His Highness and Mr. Liu, we realized that the car we designed still has many imperfections. We can't even look at it. We are really ashamed, ashamed."
Ren Siheng looked at Zhu Houzhao, then at Liu Jin, and said in an extremely ashamed tone.
"Haha, no, no, you are still amazing. Improve it quickly. I can't help but want to drive this car around the capital."
When Zhu Houzhao heard this, he immediately shook his head. He still knew clearly that if he really asked himself to research and design, he might not be able to do better than them.
This thing needs to be improved and developed after a long period of research, pondering and continuous experimentation. It can't be done perfectly in one go.
"Yes, you have actually done a great job, very good."
"We are just superfluous and unnecessary. You people know better how to design and improve it."
Liu Jin also smiled and nodded.
The car in front of us is crude, has many problems, and has many areas for improvement, but for this era, it is still an extremely amazing invention.
From internal combustion engines to automobiles, it has only been so long that they have been able to achieve this step. This is already a remarkable thing. We cannot ask too much of them. We must give them time to study and improve slowly.
.
But I believe that with the current situation of Ming Dynasty, the automobile era is coming soon.
