(I’m really sorry, these first two updates in 2021 can only be updated once. Something really delayed me. I’ll resume two updates tomorrow. I’m really sorry.)

Wei Jianjun and others are about to faint.

Just change it no matter what you say.

You know, Daqin Heavy Industries' automobiles can now be said to be the number one among domestic private enterprises.

Among domestic independent brands, there are no rivals.

If we just look at the sales volume of SUVs, then including joint venture brands and purely imported cars, no matter which brand or model, the sales volume of Daqin Heavy Industries' SUVs is not as high.

Today, Qin Feng's SUV, Fusu, Daqin Heavy Industries' first multi-functional medium and large SUV, has sales exceeding 10,000 every month.

This is an incredible sales achievement.

In terms of overall SUV sales, there is no rival. None of the others exceed 10,000 yuan. They all sell two to three thousand units a month.

And Qin Feng's Fusu sales exceed 10,000 yuan every month, what kind of concept is this!

Although, the price is not high.

The entry-level model is only 98,000 yuan, and the top model is only 128,000 yuan.

This price is very low.

But because sales are high and quantity has increased, naturally costs have also decreased.

The profit for each car exceeds 5,000 yuan.

This refers to pure profit.

Of course, this is completely incomparable with the profits of joint venture cars and purely imported cars.

However, this is already very high.

The net profit of one car is 5,000 yuan. If there are 10,000 units per month, the net profit will be 50 million yuan.

There are 600 million a year.

This is pure profit.

Net profit excluding costs, labor wages, taxes and other expenses.

Real pure profit.

This is the money that goes into Qin Feng's pocket.

In fact, if it weren't for Qin Feng's very strict quality control and very high quality control requirements, there would actually be no problem in doubling profits.

Earning 10,000 yuan per car is not much.

That month's net profit would be 100 million.

But Qin Feng's quality control requirements were too strict.

What is strict?

For example, when the workers were assembling the motor connecting wires, they sometimes accidentally made a small flaw and tore a little of the insulation protective layer on the outside of the wires. This originally had no impact.

Just stick them together with insulating tape.

It's already assembled and can't be seen. There won't be any problems.

At most, over time, due to the high temperature inside, the insulating tape may be over-oxidized and some may fall off, causing the wires to be damaged.

This kind of damage may not be fatal. It's just that the power supply may be a little insufficient.

And it is definitely not in the near future. It may be after three or five years of driving. The power supply in the wire may not be stable enough, which will make the output of the entire car not smooth enough. But it will not affect the use. It will just cause some minor problems.

It can be said that this does not affect the use at all. And it will happen a few years later. If a car has been driven for a few years, what problems will it still have?

However, Qin Feng would never allow it.

If there is a problem, the wire must be replaced and must not be taped with insulating tape.

Never allowed.

There are also some spare parts that are absolutely required to meet the standards and cannot have any flaws. Even if it does not affect the use, it is not acceptable.

Because Qin Feng's high standards naturally led to some additional losses in production, which also led to a decline in profits.

However, Wei Jianjun and others also supported it.

Because any brand can win market reputation only if its quality is good.

Otherwise, it will be over sooner or later.

Even if consumers will pay because it is cheap, it will leave a low-end image to consumers.

Because you are low-end, it is easy to break. This is acceptable to everyone.

But in the future, if you want to build a high-end brand, it will be difficult for consumers to change their inherent thinking and cognition.

Of course, what Wei Jianjun and others want to say is that after making so much money every year, Qin Feng did not take any of the money, and all of it was used to invest in self-developed engines.

Finally, in the past two years, they have continued to spend money, and they also stole a lot of things from Audi's German headquarters.

Finally some results were achieved.

If all goes well, this year, in 2000, Daqin Heavy Industry's vehicles may use self-developed engines.

Although, in terms of performance, it cannot compare with first-class European and American products.

At least 10 years behind.

Of course, this is already a very good result.

You know, before Qin Feng ordered the development of engines, civilian automobile engines were more than twenty or thirty years behind.

Now it is more than ten years behind, which is already very good.

And this mainly depends on Qin Feng reaching an agreement with Audi, allowing people to study at Audi.

At Audi, I didn't learn any technology related to engine manufacturing.

However, Qin Feng learned a lot about the assembly process.

Generally speaking, there are five main details in engine development.

One is metal casting. The engine cylinder body and other simple structural parts are generally formed by metal casting. The specific process is divided into high-pressure casting and low-pressure casting. The metal melts into a liquid and is poured into the mold. The difficulty of this process lies in the residual stress and exhaust gas during the cooling and solidification process.

, release agent spraying, etc. lead to the occurrence of defects, which reduce the yield and seriously affect the service life, because metal fatigue is the most afraid of defects. Secondly, the quality requirements of the metal material itself are also extremely high, usually cast iron or cast aluminum, high

The quality of casting raw materials has never been available in other countries, so they need to be imported from abroad.

Naturally, Qin Feng has no choice. Even if Wei Jianjun and others strengthen the research and development of high-quality cast aluminum raw materials to meet the needs of the engine, it may only bring benefits in the future. In the short term, there will be no

result.

Thirdly, for die-casting molds and die-casting machines, the best in the world are Japan and Germany, followed by Italy, and then others. The mold must be precise, durable, and suitable for automatic production. It cannot be said that after casting a few molds, they will break or leak.

Or it won’t work if you can only watch and control the heat manually. The problem of metal casting is a huge problem. To put it bluntly, it has been a problem in China since ancient times. From the sword against the full-moon scimitar to the current engine manufacturing, it is

This question. This set of technologies is a typical product of the steam age and is the foundation of all modern industries. Now that they have cooperated with the electrical industry and computer information industry, they are even more powerful.

The second problem is mechanical processing.

Excellent machining requires good lathes, turning tools, and turners. Lathes and turning tools can at least be bought at high prices from Germany, but turners are a problem. For the same part, choose different directions and routing.

out, but the service life is obviously different. What to do with these skills? The engine piston has to move back and forth tens of millions of times in the cylinder bore, and its error requirements are extremely high. Its wall surface processing requires a process called honing to ensure the cylinder bore surface.

It is wear-resistant and can adhere to an oil film to ensure sealing performance. At this time, the materials, processes, and directions of honing come again. If this process is not done well, even if the cylinder bore is bent just a little bit, the piston will move thousands of times and the engine will accelerate.

Aging. The crankshaft hole is a multi-stage intermittent elongated hole, and the requirements for dimensional accuracy, roundness, coaxiality, and surface roughness are very strict.

In this regard, Wei Jianjun and others have not learned anything. It is impossible for Germany to cultivate this kind of technology for you. This is absolutely impossible for you.

The third problem is the assembly process.

After watching "The Fast and the Furious", I felt that a car can be built by just a few people tightening screws in a warehouse and building an engine on a crane. Those are car repairs, just car repair techniques. And the assembly of the engine is not done with just one hand.

Yes, but professional assembly tools. These require experience, technology, and even more time. Some parts require specific machines for installation, and even the installation sequence of screws and tightening strength require experience and instruments. If the piston clearance is mixed

How much damage will be caused by grinding thousands of tiny hard particles. Therefore, the assembly environment, process, equipment, and technical requirements are very high. Generally speaking, if the first two steps are not done well, there will be no chance of assembly.

Gotta practice.

Fortunately, Qin Feng arranged for someone to study at the Audi headquarters in Germany.

Audi headquarters, because Qin Feng sold Audi well in China, did not embarrass Qin Feng. In other respects, it was impossible to give Qin Feng any help, and Qin Feng was blocked.

However, in terms of equipment technology, the workers of Daqin Heavy Industry were still given the opportunity to truly learn.

They actually assemble the entire Audi vehicle inside.

It can be said that in terms of vehicle assembly, the technology of Daqin Heavy Industry is very different from that of Europe and the United States.

This is all thanks to the support of Audi headquarters in Germany.

Of course, everyone gets what they need.

But for Qin Feng, it is indeed not easy.

This is also a very key reason why Daqin Heavy Industries' cars have good quality control.
