Chapter 314 If the gasoline engine is not enough, do you still need to build a diesel engine?
The hot sales of F3 can be regarded as completely opening up the sales of Nanshan engine 1.0T.
As the general manager of Nanshan Engine, Cheng Tao's mood is naturally very good.
"Mr. Cao, the production line of our 3.0T twin-turbo engine has been built, and after a period of commissioning, we can start formal mass production."
"In addition, the prototype test of the W12 engine has also been completed, and after re-revising the drawings of some parts, it can enter the stage of preparation for mass production."
"As for the 1.5T and 1.0T engines that have been mass-produced, the current production 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 don't think there's a V8 engine with a displacement of about 4.0T."
"Our Xingchen II is currently planning to use a 6.0T engine, but if there is a lower version of the 4.0T, it may be able to increase 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.
In both public and private, Cheng Tao hopes to get more engines.
Not only can Xingchen cars be used, but they can also be sold to make money.
"Mr. Cao, I also think that the 4.0T V8 engine has a certain need for research and development."
"With it, our 3.0T engine can be considered for sale on a small scale in the future."
"Once Xingchen No. 2 is successful, everyone has seen the charm of large SUVs, and 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 it at that time, the 3.0T is obviously more suitable."
"At the same time, after the V8 engine, the two V8s share the same camshaft, similar to the W12, and it is also possible to directly develop a high-horsepower W16 engine."
"In the future, it will be very meaningful for us to launch more high-end models."
Don't look at Zeng Tingting, who is only 155 tall, but 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, basically the displacement of the engine is enough."
"We only need to have some more facelifts on this basis to meet the needs of the next ten years."
Cheng Tao glanced at Zeng Tingting very gratefully.
Compared with the popular engine of 1.5T, the input-output ratio of the V8 engine is definitely worse.
And there are no plans to sell to the outside world in the future.
In this case, it is not easy for Zeng Tingting to stand up and support his point of view.
"Our engine R&D team has accumulated some experience."
"In the next step, in addition to developing products with a larger displacement, the engine suitable for hybrid models should also be carefully studied."
"Whether it's the FHEV route that Toyota and Honda are taking, or the PHEV route, the future is quite promising."
"Other than that, have you ever considered working on diesel engines?"
Cao Yang's question was a bit unexpected for Cheng Tao.
When it comes to hybrid engines, he can understand.
After all, strictly speaking, the engine used on the Xingchen 3 can also be regarded as a hybrid engine.
But the words of the diesel engine......
As we all know, Huaxia's diesel engine can be said to be "unpopular", or even "disliked"!
First of all, the first point, in the impression of most people, diesel engines are basically all kinds of tractors that suddenly emit black smoke, or rumbling heavy trucks, and the impression of diesel cars in the minds of Chinese people is: black smoke, noise, vibration, and bulkiness!
But in fact, diesel engines are more suitable for our domestic road environment.
Although the speed is not fast, stop-and-go, the diesel engine can just play a low speed and high torque, and it is more energy-saving.
In some European and American countries, diesel engines are even more popular than gasoline engines.
According to statistics, Europe, which has stricter requirements for automobile exhaust emissions, can reach more than 60% of diesel vehicles in a few years, but less than 1% in China.
"Mr. Cao, diesel engines have no application prospects in passenger cars, right?"
"Are we going to produce heavy-duty trucks in the future?"
Seeing that Cheng Tao was a little entangled, Zeng Tingting couldn't help but ask this question for him.
"In the future, whether it is our own models or other independent brand models, we will definitely go overseas."
"Because of the lack of oil products 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 fuel efficiency."
"The energy conversion rate of compression-ignition diesel engines is higher than that of ignition gasoline engines, so diesel engines and gasoline engines of the same model or displacement 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 superior to a gasoline engine in load-loading, climbing, and off-road situations. Of course, the performance at high speeds is not as good as that of gasoline cars. ”
"The third is to save money, which is what independent brands care about. After all, the diesel engine has a simple structure and low maintenance costs. ”
Cao Yang's explanation is naturally reasonable.
Cheng Tao couldn't help but retort: "Mr. Cao, as you said, the diesel engine does have these advantages, but its disadvantages are actually obvious. ”
"First, the diesel engine has a high technical content and has high processing accuracy requirements for many parts, while many domestic auto parts enterprises have not yet met the standards of many machinery manufacturing processes."
"For example, the processing accuracy of the fuel supply pump and fuel injector on the diesel engine is ridiculously high, and there is no high coordination accuracy between the two parts on the gasoline engine."
"Second, the torque of diesel vehicles is very high and the speed is very low, so a gearbox with multiple stages of transmission and the gear ratio between each stage can not jump too much, which is not a very good product in China."
"Our Nanshan gearbox is the most powerful gearbox company in China, but we have not studied this aspect of the product."
"And then there's a very critical, and most important point, which is something related to policy."
"It's something that businesses and consumers can't change."
"That is, diesel, it is a strategic material, and diesel is used for freight vehicles on the street, and diesel is also used for some large-scale equipment used in some industrial production."
"Other things like airplanes, ships, tanks, etc., also use diesel."
"And China's oil resources are not abundant, and it still depends on imports."
"After the imported crude oil is refined, part of it is diesel and part of it is gasoline, and diesel itself is a very important industrial material and strategic material, if all the private cars go to fill up with diesel, then the diesel will definitely not be enough, and the extra gasoline will be wasted."
"So I don't think it's a good direction to spend a lot of R&D resources on diesel engines."
Cheng Tao has also worked in Nanshan Group for several years, and he has a certain understanding of Cao Yang's character.
Knowing that in this case, you can just say what you have to say, and you don't need to think too much.
"Mr. Cheng, what you said makes sense, but our diesel engine is mainly oriented to the future export market."
"I believe that when the time comes, Great Wall Motors and Chery Automobile, which are independent brand car companies, will be interested."
"As for the technical and processing issues, it's a problem for other businesses."
"But for us at Nanshan, it's not a problem at all."
"Nanshan equipment is now able to produce some five-axis CNC machine tools, and is still worried that the accuracy of the parts does not meet the requirements?"
"As for the technology, when we developed the 1.5T engine, the technology accumulation was much weaker than now, didn't we also get it."
"Now you're worried that you won't be able to do it?"
Cao Yang is obviously optimistic about the development of diesel engines.
The main thing is this thing, and it can be used not only in passenger cars.
Even after 20 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.
If you don't do some related 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 use of trucks first?"
"In that way, we can sell it to some domestic companies relatively quickly."
"If it's used in passenger cars, I don't think there will be any demand for it in a short period of time."
Zeng Tingting stood in the perspective of sales and gave her own suggestions.
After all, if the diesel engine is developed at that time, she needs to be responsible for sales.
It can't really be regarded as a technical reserve, right?
"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 general displacement diesel engine, domestic companies such as Cummins and Weichai Power are already producing it."
"If we want to do it, we have to have a large displacement."
"Only diesel engines with 11L, 13L or even 15L displacement are competitive."
Cheng Tao can also see Cao Yang's determination to engage in oil extractors, so he began to give some suggestions seriously.
"How many displacement diesel engines are engaged in first, you can study the market demand."
"In addition to the large-displacement diesel engine used in heavy trucks, the 1.5T diesel engine used in cars is also developed simultaneously."
"The engine of this displacement should be used the most in cars."
Cao Yang will not give up the diesel engine.
Whether it is the overseas automobile market, the truck market, or the construction equipment, diesel engines have a very broad market prospect.
If Nanshan Group wants to shine in the automotive industry, it naturally can't just toss in the passenger car market.
This is the good thing in private enterprises, what the boss decides, the people below have to do even if they don't want to.
However, after Cao Yang went to Nanshan Engine for a few days, Dai Hanbiao of Nanshan Auto Parts found an opportunity.
Cao Yang had been busy in Xingchen Automobile before, and he was embarrassed to disturb.
Now that we have time to guide Nanshan engine, then also guide Nanshan auto parts, this requirement is not too much, right?
Considering that auto parts are also a very critical and very important link, Cao Yang put down the matter of Xingchen Automobile and listened to Dai Hanbiao's report on the research progress of various parts.
"Mr. Cao, about the four-wheel drive system, we have reviewed it and are ready to make a set of our own full-time four-wheel drive system, but the design of differentials and other parts has encountered a lot of problems."
Dai Hanbiao knows how powerful Cao Yang is.
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 the car, many people may think of Mercedes-Benz's 4 MATIC, BMW's xDrive, and Audi's Quattro, and it is really necessary for us to create a four-wheel drive system that belongs to Xingchen Automobile."
"And give it a relatively easy name to remember, 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.
Don't look at the later generations, many automobile companies have their own four-wheel drive systems, in fact, there are not many suppliers who really do four-wheel drive systems.
BorgWarner, Magna, GKN, JTEKT, just a few that have done well.
The remaining part, such as Honda Motor Co., Ltd., will also produce some of the four-wheel drive systems at their own factories, which are only supplied for their own use.
Dai Hanbiao is now arranging for someone to develop a four-wheel drive system, apparently preparing to take this set of key component technology into his own hands.
Otherwise, if the four-wheel drive system of Xingchen Automobile needs to be purchased from the outside in the future, it is likely to become one of the most expensive parts purchased from the outside in addition to the seat.
"Audi's Quattro is also the most famous all-wheel drive system. Fight to fame in WRC events. ”
"This WRC event, also known as the World Rally Championship, has to go through a variety of terrains such as sand, ice, snow, mud, rain, etc., and the whole race is thousands of kilometers, which has almost cruel requirements for the handling and stability of a car."
"In the '80s, the Audi A2 achieved amazing results in the WRC. But it was also called an unfair race by many people, because at that time other cars participating in the race were rear-wheel drive, and only Audi used a four-wheel drive system for the first time, so it formed an absolute crush. ”
"Later, the organizers changed the rules to require all four-wheel drive cars to increase the weight, but it still couldn't stop the power of Audi's four-wheel drive, and then Audi was simply banned from using the Quattro system."
"Although it led to Audi's withdrawal from the WRC, it also made Quattro Audi's biggest selling point."
"Is our all-wheel drive system directly designed with reference to Audi's Quattro, so that when it is promoted in the future, it can also step on Audi's shoulders?"
Zeng Tingting interjected beside her.
What is the selling point of a car is an important question.
If you can't find a selling point, it's hard to do the work of the sales department.
Therefore, Cao Yang also involved some 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 patents of the four-wheel drive system are 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 also make a stable enough four-wheel drive system, but Huaxia is not a company that produces the four-wheel drive system."
"In fact, it's not that the ability is impossible, but that it will be checked and balanced by patents."
"A simple four-wheel drive system is difficult to move under complex patent barriers, and after monopoly, we can see a very natural situation, and models equipped with four-wheel drive systems are often linked to high prices."
"So it's like the Audi Quattro that Minister Zeng said, but in fact, its structure and principle are not as complicated as everyone thinks."
"At the heart of the system is the Torsen differential."
"As a differential, which has been around for many years, the Torsen differential has a worm and worm planetary gear structure."
"The way it works is purely mechanical, without any electronic system intervention."
"The basic principle of this differential is to take advantage of the one-way transmission characteristics of the worm gear, that is, the movement can only be transmitted from the worm to the worm gear, and the reverse is self-locking."
"As a result, the front and rear torque distribution can be adjusted in a timely and reliable manner than the electro-hydraulically controlled central differential system, and the power can be smoothly distributed to the front and rear output shafts via planetary gears, enabling the front and rear axles to be driven."
"The power transmission characteristics of the worm gear are just the opposite of the spur planetary gears of a normal open differential, and it automatically distributes the power to the output shaft on the side with more resistance."
"If we had to design it ourselves, there would be no problem."
"But there are a lot of problems in circumventing the patents of manufacturers such as Audi or Magna."
Obviously, there is a reason why Dai Hanbiao will take out the four-wheel drive system as a subject and report to Cao Yang.
If it was so easy to find a circumvention patent and develop a good system, he would definitely not want to bother Cao Yang.
Otherwise, if you look for Cao Yang for everything, how can you mention their importance?
"Mr. Dai, in fact, I think everyone's thinking has fallen into a misunderstanding?"
"Why do we use traditional technology for all-wheel drive like companies like Audi, Mercedes-Benz and BMW?"
"We can completely change to a new model and engage in electric four-wheel drive."
When Cao Yang said this, Dai Hanbiao was stunned.
Electric 4WD?
What the hell is this?
Why do you feel so unfamiliar?
"Unlike the study of mechanical four-wheel drive, which is very difficult, the design of electric four-wheel drive is very simple."
"After laying out the wiring system, and then equipping the motor on the rear axle, you can control the power through the electronic control unit, and the front and rear motors can distribute the power as they want, and the design difficulty has dropped a lot."
"Compared with the engine, the motor can reach the highest speed and burst the maximum torque in an instant, and the speed of the motor is often much higher than the engine, so the instantaneous power output of the electric four-wheel drive will be stronger than the traditional mechanical four-wheel drive, which is more conducive to the vehicle to get out of trouble and accelerate from start."
"Compared with the mechanical four-wheel drive of traditional fuel vehicles, the electric four-wheel drive cancels the gearbox, transfer case and other parts, making the structure simpler, the transmission efficiency is higher, and the loss of power in the transmission process is reduced."
"The electric four-wheel drive directly distributes the power by controlling the motors of the front and rear axles, compared with the mechanical transmission, the response speed of the electric four-wheel drive is faster and more accurate, and when driving on complex roads, the vehicle can reasonably distribute the power and torque of the four wheels in a timely manner according to the real-time adhesion of the four wheels and road conditions."
"Due to the simple structure, the electric four-wheel drive system can often be adapted to different models, and there is no need to consider the traditional axle length, transfer case, and differential lock layout like fuel vehicles, and different models need to re-layout the four-wheel drive system, so the cost of electric four-wheel drive is lower."
"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."
"In the traditional fuel engine vehicle, it will bring some additional difficulties, and some power distribution between the engine and the generator needs to be fully considered."
"Even in extreme cases, it can only be considered to be used first on FHEV models."
"But at least our Xingchen 3 now has a hybrid system, and there is no problem with this electric four-wheel drive on it."
"Whether it can be carried on Xingchen-2 or not, you need to study it carefully."
As soon as Cao Yang said this, Dai Hanbiao and Zeng Tingting's eyes 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 gain today.
For Zeng Tingting, she felt that when the new car was promoted in the future, she could use this electric four-wheel drive system as a selling point to publicize.
Electrified parts, compared with traditional mechanical parts, always give people a feeling of more advanced technology.
On the other hand, the cost of electric four-wheel drive is cheaper than that of traditional four-wheel drive systems.
This makes it even more enjoyable.
"Mr. Cao, isn't there any disadvantage to this electric four-wheel drive?"
Happy is happy, Dai Hanbiao is also worried that he will step on thunder in the process of development.
So take this opportunity to be ready to make sure it is clear.
"No matter what parts and systems, they definitely have their own shortcomings, and electric four-wheel drive is no exception."
"The electric four-wheel drive relies on the instantaneous torque burst of the motor to get out of trouble, which is 'vigorously out of the miracle'."
"Under normal circumstances, electric four-wheel drive models are not equipped with transfer cases and differentials."
"Therefore, in the case of one group or one wheel slipping, the vehicle cannot distribute the power of the skidding wheels to the adhesion wheels, making the electric four-wheel drive not as capable of getting out of trouble 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 engage in a pure off-road vehicle, take a hard-core off-road route, and be equipped with a non-load-bearing body, then you can consider equipping the electric four-wheel drive system with a simple transfer case and differential."
"Or buy a simple time-sharing four-wheel drive system directly from the outside, which can also meet the needs of hardcore off-road vehicles."
When Cao Yang said this, Dai Hanbiao and Zeng Tingting were relieved.
This shortcoming, for the current Xingchen Automobile, is not a shortcoming at all.
Because the future models do not mean to go hard-core off-road vehicles.
And Cao Yang himself knows very well in his heart that in ten years, urban SUVs are king.
Only urban SUVs have reached a certain stage of development, and everyone has begun to pursue something else.
That's when the opportunity for a hardcore SUV comes.
