Rebirth 99 to become a car giant

The hot sale of F3 has completely opened up the sales of Nanshan Engine 1.0T.

As the general manager of Nanshan Engine, Cheng Tao is naturally in a very good mood.

"Mr. Cao, our 3.0T twin-turbocharged engine production line has been built. After a period of debugging, we can start formal mass production."

"In addition, the prototype test of the W12 engine has also been completed. After re-modifying the drawings of some parts, it can enter the mass production preparation stage."

"As for the 1.5T and 1.0T engines that have been mass-produced, the current capacity load is relatively high."

"There is only a 2.0T engine production line, and the capacity utilization rate is less than 50%."

"According to the current situation, basically the main research and development work of the engine has been completed."

"We will soon be able to form a series of engine products of 1.0T, 1.5T, 2.0T, 3.0T and 6.0T."

"But I feel that there is a lack of a V8 engine with a displacement of about 4.0T in the middle."

"Our Xingchen II currently plans to use a 6.0T engine, but if there is a low-profile version of 4.0T, it may bring sales to a higher level."

"Similarly, Xingchen-1 uses a 3.0T engine, although there are plans to install a 6.0T high-performance version in the next step."

"But a 4.0T V8 engine may actually be more suitable for it."

Nanshan Engine must continue to develop new engines in order to have the possibility of progress and expansion.

Whether in public or private, Cheng Tao hopes to develop more engines.

Not only can the star car be used, but it can also be sold to make money.

"Mr. Cao, I also think that the 4.0T V8 engine is necessary for research and development."

"With it, our 3.0T engine can be considered for small-scale external sales in the future."

"Once Xingchen 2 is successful and everyone sees the charm of large SUVs, maybe domestic independent brand car companies will immediately follow up and launch large SUVs."

"Although the 2.0T engine can also be used to match at that time, the 3.0T engine is obviously more suitable."

"At the same time, with the V8 engine, it is possible to directly develop a high-horsepower W16 engine by using two V8s to share the camshaft, similar to the W12."

"It will make sense for us to launch more high-end models in the future."

Although Zeng Tingting is only 155 in height, she likes big cars very much.

The future Xingchen No. 2 is the model she especially wants to buy.

"What Minister Zeng said is very reasonable. After we have V8 and W16, the displacement of the engine is basically enough."

"In the future, we only need to make more changes on this basis to meet the needs of the next ten years."

Cheng Tao gave Zeng Tingting a grateful look.

Compared with the explosive 1.5T engine, the input-output ratio of the V8 engine is definitely worse.

And there are no plans to sell it in the future.

Under such circumstances, it was not easy for Zeng Tingting to stand up and support his point of view.

"Our engine research and development team has accumulated some experience."

"In the next step, in addition to developing products with larger displacement, the engines suitable for hybrid models should also be carefully studied."

"Whether it is the FHEV route that Toyota and Honda are taking, or the PHEV route, the future is quite promising."

"Aside from that, have you guys considered working on diesel engines?"

Cao Yang's question was a bit beyond Cheng Tao's expectation.

As for the hybrid engine, he can understand it.

After all, strictly speaking, the engine used on Xingchen 3 can also be regarded as a hybrid engine.

But with diesel engines...

As we all know, China's diesel engines can be said to be "unpopular", or even "disgusted"!

First of all, in the minds of most people, diesel engines are basically all kinds of tractors that emit black smoke, or rumbling heavy trucks, and the impression of diesel vehicles in the minds of Chinese people is: black smoke , noise, vibration, bulky!

But in fact, diesel engines are more suitable for our domestic road environment.

Although the speed is not fast, stop and go, but the low-speed high-torque diesel engine can just play out, and it is more energy-efficient.

In some European and American countries, diesel engines are even more popular than gasoline engines.

Some organizations have done statistics, and Europe, which has stricter requirements on vehicle exhaust emissions, will see the penetration rate of diesel vehicles reach more than 60% in a few years, while in China it will be less than 1%.

"Mr. Cao, there is no future for diesel engines to be used in passenger cars, right?"

"Are we going to produce heavy trucks in the future?"

Seeing that Cheng Tao was struggling, Zeng Tingting couldn't help asking this question for him.

"In the future, whether our own models or models of other self-owned brands, we will definitely go overseas."

"Because of poor oil quality in China, diesel engine cars really have no future."

"But it's different in foreign countries. The advantages of diesel engines are still obvious."

"The first is to save fuel."

"The energy conversion rate of compression-ignition diesel engines is higher than that of ignition-type gasoline engines, so diesel engines and gasoline engines of the same model, or the same displacement, diesel engines are more fuel-efficient."

"The second is that the torque is large and the strength is sufficient."

"The diesel engine is very powerful even at low revs. This is worse than the gasoline engine in the case of load, climbing and off-roading. Of course, the performance at high speeds is not as good as the gasoline car."

"The third is to save money, which is what self-owned brands care about. After all, diesel engines have a simple structure and low maintenance and maintenance costs."

Cao Yang's explanation in this way is naturally reasonable.

But Cheng Tao couldn't help retorting: "Mr. Cao, as you said, the diesel engine does have these advantages, but its disadvantages are actually obvious."

"First, diesel engines have high technological content and require high processing precision for many parts, while domestic auto parts companies have not yet met the standards for many mechanical manufacturing processes."

"For example, the machining accuracy of the fuel pump and fuel injector on the diesel engine is ridiculously high, but there is no high matching accuracy requirement between these two parts on the gasoline engine."

"Secondly, diesel vehicles have a lot of torque and very low speed, so a gearbox with multi-stage transmission and the transmission ratio between each stage cannot be jumped too much is needed. There is no very good product in China for this."

"Our Nanshan gearbox is considered the most powerful gearbox company in China, but we haven't researched products in this area."

"There is another very critical and most important point, which is something related to policy."

"This is something that neither businesses nor consumers can change."

"That is diesel, which is a strategic material. Freight vehicles on the street use diesel, and some large-scale equipment used in some industrial production also use diesel."

"In addition, things like airplanes, ships, and tanks also use diesel."

"However, Huaxia's oil resources are not rich, so we still have to rely on imports."

"After the imported crude oil is refined, part of it is diesel and part of it is gasoline. Diesel itself is a very important industrial material and strategic material. If all private cars are filled with diesel, then the diesel will definitely not be enough, and The extra gasoline is wasted."

"So I think it is not a good direction to spend a lot of research and development resources on diesel engines."

Cheng Tao has also worked in Nanshan Group for several years, so he has a certain understanding of Cao Yang's character.

Knowing this situation, just say what you have to say directly, without thinking too much.

"Mr. Cheng, what you said is reasonable, but our diesel engines are mainly aimed at the future export market."

"I believe that self-owned brand car companies such as Great Wall Motors and Chery Automobile will be interested."

"As for technology and processing issues, it's a problem for other companies."

"But for our Nanshan Group, this is not a problem at all."

"Nanshan Equipment is now able to produce part of the five-axis CNC machine tools. Are you still worried that the accuracy of the parts will not meet the requirements?"

"As for the technology, when we first developed the 1.5T engine, the technology accumulation was much weaker than it is now, so we can't figure it out."

"Now you're worried that you won't be able to figure it out?"

Cao Yang is obviously optimistic about the development of diesel engines.

The main thing is this thing, not only can be used in passenger cars.

Even after twenty years, many heavy trucks and special vehicles still need to use diesel engines.

After the further development of Nanshan Group, it is inevitable to expand related businesses.

Without doing some relevant technology accumulation, how will you expand your business in the future?

"If you want to study diesel engines, I think you can consider studying the ones used on trucks first?"

"That way we can sell it to some domestic companies relatively quickly."

"If it is used in passenger cars, I think there should be no demand in a short time."

From the perspective of sales, Zeng Tingting gave her own suggestions.

After all, if the diesel engine is developed by then, she will be required to be in charge of sales.

It can't really be regarded as a technical reserve, can it?

"What Minister Zeng said is also reasonable. The most promising application of diesel engines in China is indeed heavy trucks."

"However, if it is a diesel engine with a general displacement, domestic companies such as Cummins and Weichai Power are already producing it."

"If we want to do it, we have to use a large displacement."

"11L, 13L or even 15L diesel engines are competitive."

Cheng Tao could see Cao Yang's determination to develop oil extraction machines, so he began to seriously give some suggestions.

"Specifically, how many displacement diesel engines should be produced first, you can study the market demand."

"In addition to the large-displacement diesel engine used on heavy trucks, the 1.5T diesel engine used on cars has also been developed simultaneously."

"The engine with this displacement should be used the most in cars."

Cao Yang will not give up the diesel engine.

Regardless of whether it is the overseas automobile market, the truck market, or engineering equipment, diesel engines have a broad market prospect.

If Nanshan Group wants to shine in the automotive industry, it cannot just toss in the passenger car market.

This is the good thing about private companies. If the boss decides, the people below have to do it even if they don't want to.

However, after Cao Yang went to Nanshan Engine to work for a few days, Dai Hanbiao of Nanshan Auto Parts found an opportunity.

Cao Yang had been busy at Xingchen Motors before, so he was too embarrassed to bother him.

Now I have time to instruct Nanshan Engine, so I also instruct Nanshan Auto Parts, isn't this request too much?

Considering that auto parts are also a very critical and important link, Cao Yang put aside the matter of Xingchen Automobile and listened carefully to Dai Hanbiao's report on the research progress of each part.

"Mr. Cao, regarding the four-wheel drive system, we have reviewed it and are planning to build our own full-time four-wheel drive system. However, we have encountered many problems in the design of the differential and other parts."

Dai Hanbiao knew how powerful Cao Yang was.

At this time, it is natural to "squeeze" it well in order to speed up the research of new technologies.

"When it comes to the four-wheel drive system of a car, many people may think of Mercedes-Benz's 4MATIC, BMW's xDrive, and Audi's Quattro. It is indeed necessary for us to create a four-wheel drive system that belongs to Star Motors."

"And give it a relatively easy-to-remember name as one of the focuses of future publicity."

Cao Yang was not surprised to see Dai Hanbiao discussing the four-wheel drive system with him.

Although many car companies in later generations have their own four-wheel drive systems, in fact, there are not many suppliers that actually make four-wheel drive systems.

BorgWarner, Magna, GKN, and JTEKT are just a few that have done well.

The remaining part, such as Honda Motor and other companies, will also produce part of the four-wheel drive system in their own factories, only for their own use.

Dai Hanbiao is now arranging people to develop the four-wheel drive system, obviously preparing to take this set of key component technologies into his own hands.

Otherwise, if the four-wheel drive system of Xingchen Motor needs to be purchased from outside in the future, it is likely to become one of the most expensive parts purchased from outside except for the seat.

"Audi's Quattro is also the most famous four-wheel drive system. It became famous in the WRC competition."

"This WRC event, that is, the World Rally Championship, needs to experience various terrains such as sand, ice, snow, mud, rain, etc. The entire race is thousands of kilometers long. Stability has almost cruel requirements."

"In the 1980s, the Audi A2 race car achieved amazing results in WRC. But it was also called an unfair race by many people, because at that time other cars participating in the competition were all rear-wheel drive, and only Audi adopted the four-wheel drive system for the first time. , so it formed an absolute crush."

"Later, the organizers revised the rules to require all four-wheel drive cars to increase the counterweight, but it still couldn't stop the power of Audi's four-wheel drive. Later, it simply banned Audi from using the Quattro system."

"Although it caused Audi to withdraw from the WRC competition, it also made Quattro Audi's biggest selling point."

"Can our four-wheel drive system be designed directly with reference to Audi's Quattro, so that when we promote it in the future, we can also step on Audi's shoulders?"

Zeng Tingting interjected beside her.

What is the selling point of a car is a very important question.

If you can't find a selling point, the work of the sales department will be difficult to carry out.

Therefore, Cao Yang also involved part of the sales department in the early development of many technologies.

I even hope that some employees in the sales department can understand a little bit of technology, so that they can better promote their cars.

"The technical patent of the four-wheel drive system is blocked in the hands of foreign capital. Even if everyone knows the principle of the four-wheel drive system, the basic industrial manufacturing capacity can produce a sufficiently stable four-wheel drive system, but Huaxia has no company that produces the four-wheel drive system until now. .”

"In fact, it's not that the ability is insufficient, but that it will be checked and balanced by patents."

"Simple four-wheel drive systems are difficult to move forward under complex patent barriers. After a monopoly, we can see a very natural situation. Models equipped with four-wheel drive systems are often linked to high prices."

"So just like the Audi Quattro mentioned by Minister Zeng, its structure and principle are not as complicated as everyone imagined."

"The heart of the system is the Torsen differential."

"As a differential that has been born for many years, the Torsen differential is a worm and worm planetary gear structure."

"The way it works is purely mechanical, without any electronic intervention."

"The basic principle of this differential is to use the one-way transmission characteristics of the worm gear, that is, the motion can only be transmitted from the worm gear to the worm gear, and self-locking occurs in the reverse direction."

"Therefore, the front and rear torque distribution can be adjusted more timely and reliably than the electronic hydraulic control center differential system, and the power can be smoothly distributed to the front and rear output shafts through the planetary gears, thereby driving the front and rear axles."

"The power transmission characteristics of the worm gear are just opposite to the spur planetary gears of ordinary open differentials. It can automatically distribute power to the output shaft on the side with greater resistance."

"If we want to design it ourselves, there is no problem."

"However, there are many problems in avoiding the above patents of manufacturers such as Audi or Magna."

Obviously, there is a reason why Dai Hanbiao took the four-wheel drive system as a subject to report to Cao Yang.

If it is so easy to find circumvention patents and develop a good system, he definitely doesn't want to bother Cao Yang.

Otherwise, they would look to Cao Yang for everything, how would they be able to realize their importance?

"Mr. Dai, actually, I think everyone's thinking has fallen into a misunderstanding?"

"Why do we have to use traditional four-wheel drive systems like companies such as Audi, Mercedes-Benz and BMW?"

"We can completely change to a brand new model and engage in electric four-wheel drive."

When Cao Yang said this, Dai Hanbiao was stunned.

Electric four-wheel drive?

What the hell is this?

Why do I feel so strange to myself?

"Different from the difficulty of studying mechanical four-wheel drive, the design of electric four-wheel drive is very simple."

"After laying out the wiring system, and then installing a motor on the rear axle, the power can be adjusted through the electronic control unit. The front and rear motors can distribute the power as they want, and the design difficulty has dropped a lot."

"Compared to the engine, the motor can reach the highest speed and burst out the maximum torque in an instant, and the speed of the motor is often much higher than that of the engine, so the instantaneous power output of the electric four-wheel drive will be stronger than that of the traditional mechanical four-wheel drive, which is more conducive to the vehicle's escape and acceleration from the start.”

"Compared with the mechanical four-wheel drive of traditional fuel vehicles, the electric four-wheel drive eliminates the gearbox, transfer case and other components, making the structure simpler, the transmission efficiency higher, and reducing the loss of power during transmission."

"Electric four-wheel drive directly distributes power by controlling the motors of the front and rear axles. Compared with mechanical transmission, electric four-wheel drive responds faster and more accurately. When driving on complex roads, the vehicle can control the vehicle according to the real-time adhesion of the four wheels and road conditions. Timely and reasonable distribution of power and torque to the four wheels."

"Because of its simple structure, the electric four-wheel drive system can often be adapted to different models. It does not need to consider the traditional axle length, transfer case, and differential lock layout like fuel vehicles. Different models need to re-layout the four-wheel drive system. Therefore, the electric four-wheel drive lower cost."

"The most important thing is that after our system is developed, it can be perfectly combined with BEV, PHEV and FHEV models in the era of new energy vehicles in the future."

"Even the most suitable scenario for an electric four-wheel drive system is a model with a battery."

"On the traditional fuel engine vehicle, it will bring some additional difficulties, and it is necessary to fully consider some issues such as power distribution between the engine and the generator."

"Even in extreme cases, we can only consider using it on FHEV models first."

"But at least our Xingchen 3 now has a hybrid system, and there is no problem with using this electric four-wheel drive on it."

"Whether it can be carried on Xingchen 2 or not, you need to study it carefully."

When Cao Yang said this, the eyes of Dai Hanbiao and Zeng Tingting became brighter and brighter.

For Dai Hanbiao, finding a four-wheel drive system that is less difficult to develop but seems to be more technologically advanced is the biggest achievement today.

As for Zeng Tingting, she feels that when the new car is promoted in the future, this electric four-wheel drive system can be well promoted as a selling point.

Compared with traditional mechanical parts, live parts always give people a feeling of more advanced technology.

However, the cost of electric four-wheel drive is cheaper than traditional four-wheel drive system.

This makes people even more happy.

"Mr. Cao, isn't there any shortcoming in this electric four-wheel drive?"

Happy to be happy, Dai Hanbiao is also worried that he will step on a thunder during the development process.

So take this opportunity to be prepared to confirm clearly.

"No matter any parts and systems, they must have their own shortcomings, and the electric four-wheel drive is no exception."

"Electric four-wheel drive relies on the instantaneous torque burst of the motor to get out of trouble, that is, 'powerful miracles'."

"Under normal circumstances, electric four-wheel drive models are not equipped with transfer cases and differentials."

"So in the case of one or one of the wheels slipping, the vehicle cannot distribute the power of the slipping wheel to the wheels with adhesion, making the ability of the electric four-wheel drive to get out of trouble not as good as the traditional mechanical four-wheel drive."

"Of course, our current models, even SUVs, are essentially urban SUVs, not hardcore off-road vehicles."

"So this one shortcoming is not very obvious."

"In the future, if you want to make a pure off-road vehicle, take the hard-core off-road route, and equip a non-load-bearing body, then you can consider installing a simple transfer case and differential on the electric four-wheel drive system."

"Or directly buy a simple part-time four-wheel drive system from outside, which can also meet the needs of hard-core off-road vehicles."

When Cao Yang said this, both Dai Hanbiao and Zeng Tingting breathed a sigh of relief.

This shortcoming is not a shortcoming at all for the current Xingchen Automobile.

Because the future models do not intend to use hard-core off-road vehicles.

And Cao Yang himself knows very well that within ten years, urban SUVs will be king.

Only when urban SUVs have developed to a certain stage, everyone begins to pursue other things.

At that time, it was time for the hard-core SUV to come.
