Siheyuan: Heavy Industry Revitalizes the Country

Cao Tianwei accepted it somewhat reluctantly.

It can be seen that he is not very interested in gearbox tuning.

Soon, several drivers who participated in the road test completed twenty laps.

Under the arrangement of Director Ma, I also participated in filling out the questionnaire.

However, when the results were summarized to Fang Xiang, he did not get much useful information.

I don’t know if this is the first time for the drivers to drive this type of vehicle.

Or it was because Fang Xiang was the chief engineer.

Basically, everyone filled in the five-star satisfaction option.

When seeing this result, Fang Xiang suddenly felt helpless.

Unfortunately, it was a little too late, and the vehicles had already been dismantled for inspection and data collection.

Otherwise, you should get in the car and try it yourself.

After discovering this problem, Fang Xiang remembered that he had not driven the first small car for a test drive.

Suddenly I felt like I had lost my mind from drawing the diagrams.

After sighing secretly, he walked into the workshop.

"How is it, is there any problem with the parts?"

Fang Xiang squatted on the ground, moved closer to Cao Tianwei who was smoking, and lit a cigarette.

“They are all very good. These manufacturers have been cooperating with us for half a year.

This is not the first time that parts have been customized.

They are all very attentive.

At least in terms of quality, everything is in line with our standards.

The only problem was that one of the engines had a slight scratch on the cylinder wall.”

Cao Tianwei first gave an excellent evaluation and then pointed out the problem at the end.

"Just a tiny scratch?"

Fang wanted to look over and saw spare parts all over the floor, so he wanted to take a look.

“Well, I asked, and it was because a driver continued to drive violently after wading through the water.

It was probably caused by gravel entering the engine through the air intake."

Cao Tianwei stood up and took Fang Xiang to the dismantling site of another car.

He flipped up the engine block, then took a flashlight, turned it on, and illuminated one of the cylinders.

Sure enough, a very tiny scratch can only be captured when the light keeps changing its angle.

"I remember now, it's a problem with the air intake system filter."

Fang Xiang immediately understood where the problem lay.

Today's air intake filter is extremely simple, it is a carbonized charcoal filter.

Not only is the filtering effect poor, but it also produces a large amount of debris.

It was not until the 70s that vehicles became widely popular among the people and scratches appeared.

The manufacturers gradually realized this problem and replaced the cotton fiber and non-woven filter elements.

"Intake filter? What should I do then?"

Cao Tianwei was also very sensitive to this problem, but he didn't know how to solve it.

"Let me think..."

Fang Xiang was also a little troubled.

Cotton fibers and non-woven fabrics do exist today, but their applications have not been widely spread.

Even if Luoqi purchases, the quantity will not be too large, so the cost cannot be reduced at all.

Not to mention that the masks used in hospitals now are still made of cotton.

You can't replace the carbonized charcoal filter with cotton, right?

"If you ask me, it doesn't matter.

Now everyone is using it this way, can we be an exception? "

Since Cao Tianwei was transferred to Luoqi, he has been frequently learning various automotive knowledge.

Just to keep up with Fang Xiang and not fall behind.

Especially after Fang Xiang started designing small cars, Cao Tianwei bought many books related to the automotive industry at his own expense.

I can't say that I know everything about the mainstream car designs in the world today, but I do know a lot.

"We have to manage it. This will be our chance to brag about it later."

Fang Xiang doesn't see it that way.

Think about WoWo, which was a little-known small manufacturer back then.

Later, it focused on the safety segment for many years and established its position as a second-tier luxury brand.

Therefore, details are what need to be paid attention to from the very beginning.

What others can't do, I can do.

What others can do, I can do better.

“I’ll go back and draw a new filter diagram, make a new filter, and replace it.

After the car is installed, tell me so we can both try it out."

Anyway, it's just a matter of convenience and won't take long.

After saying that, Fang Xiang threw away the cigarette butt and returned to the office.

Today's filter element can almost be said to be very simple, just a square box filled with carbonized charcoal.

Fang Xiang directly drew a drum-type structure and optimized the air intake method of the filter element.

A layer of breathable cotton paper is added to the inner wall of the drum.

It can wrap up the debris generated by bumps and prevent it from entering the intake duct.

A few holes were dug under the drum so that the debris could fall out.

After finishing it, Fang Xiang thought of Wo Wo again. In addition to inventing the three-point seat belt, what else did they invent?

Yes, there is also a one-piece cage body, child safety seats, booster cushions, airbags, head and neck protection system and side impact protection system.

It is still quite difficult to produce an integral cage-type body with the current technology, after all, there is a lack of necessary high-precision machine tools.

But there is no problem with child safety seats and booster cushions, this is completely achievable.

The head and neck protection system is not difficult to make. Most of the functions can be achieved by making some minor changes to the headrest.

Although airbags were invented a few years ago, they are still somewhat difficult to manufacture, especially in China.

I'm afraid this will have to be put on hold for now.

Not to mention the side impact protection system, which is achieved based on the integrated body structure.

There is no way to do that now.

Are there any other selling points that can be added?

Fang wanted to go downstairs and asked Xing Yi to drive a jeep over. After getting in the car, he began to compare the functions with those of later vehicles.

Automatic wipers? No, pass.

Anti-glare rearview mirror? Never mind.

Automatic cruise control? This is difficult and the cost is too high.

Automatic headlights? No, either. . . But nowadays, there are foot-operated high-beam switches, which can be integrated behind the steering wheel.

Together with other lighting controls.

By the way, you can also add an armrest box.

Looking at the empty space next to him, Fang thought of this extremely convenient thing.

When the compact car was being designed, it was omitted due to space issues, but now it can be added.

Then there is the dashboard, which is now extremely simple. Although Fang Xiang made some changes, it doesn’t look much different.

Thinking of some classic design elements of later BMWs, and adding the tilted driving seat, Fang Xiang felt that it could be further modified.

Oh, we need to add a switch for the emergency double flash lights here.

Looking at the center console, there is no air conditioner and screen.

Forget about the screen, but the air conditioner...

Air conditioning is quite expensive. It’s not that it cannot be installed, but nowadays, only the most expensive and top-of-the-line cars can have air conditioning installed.

The cost is simply too high.

But if the air conditioning doesn’t work, you can open a hot air duct.

It is still very useful in winter.

Since the heater is turned on in the front, can we add an air outlet in the back row?

By the way, there is also a handbrake. Nowadays, the handbrake of vehicles is located on the center console.

Since the central control has been greatly modified, the handbrake can also be moved next to the floor gear position.

There are also hand-cranked windows, which can be turned into electric ones by adding a motor. This is possible.

Then there is the seat material, which has been changed from cloth to velvet, which has improved the grade.

Finally, a trunk escape function, sun visors and child locks were added.

After thinking for a long time, he felt that there was nothing that needed to be changed inside the car for the time being, so Fang Xiang got out of the car and walked around it.

Looking at the round lights on the front of the car, he thought of the lighting factory in later generations, but then Fang Xiang sighed.

This candle lamp was not used until the 21st century before it was gradually phased out.

LED and xenon lamps are expensive, but the technology is not mature and the lifespan is short. . .

I'm afraid I'm overthinking it.
