Regarding the concept of Xu Fufang's words, Li Fanyu thought so. Pen & Fun & Pavilion www.biquge.info

The development of China's auto market is not high in maturity, and there is basically no car culture to talk about. As a result, a large part of consumers are irrational when choosing a car.

In fact, as a pickup truck with a working nature that is far greater than the nature of driving, a fuel-efficient and powerful diesel engine is the best choice. Throwing out some extremely cold northern cities, the diesel version of the pickup truck is definitely an advantage compared to the gasoline version.

Even if there is a problem with the oil product, as Xu Fufang said just now, it is nothing more than the cycle of changing the oil filter and cleaning up the carbon deposits is shorter than normal.

But if you don't buy it, you can't do anything about it.

Li Fanyu has experienced two time and space, and he has a good understanding of the consumption habits of the Chinese auto market. In fact, he has done a lot of things in order to compromise the market before this. In the several models currently on the market, some changes have been made compared with the original version.

But I still didn't expect that this time the diesel power would actually hit the street......

It's very melancholy.

Seemingly...... I have to take time to give the market a positive and three views......

Li Fanyu touched his chin and thought like this.

With this matter in mind, he put down his hand, "Okay, I don't care about him now." By the way, how did the four of you all get together?

"Hehe!" Hearing him ask, Liu Qing piled up a coquettish smile, "Didn't I tell you just now, we are taking a nap." ”

"Okay Qingzi, don't sell it to him. Xu Fufang shook his head with a smile, and said to Li Fanyu: "When have you ever seen our four R&D projects broken? ”

Li Fan said foolishly: "What assistance?"

Xu Fufang smiled: "Hasn't Ruizi been working on the A4 high-performance version?" This kid called us last night and said...... Hey, let this kid tell you for himself. ”

Seeing Li Fanyu's gaze on himself, Wang Rui bared his teeth, and saluted hippiely: "Report Brother Fan, I lived up to expectations, and after leading 4 groups to fight hard for five months, I finally made a breakthrough!"

Li Fanyu was a blout in the past, "Don't ask for credit, let's talk about the point!"

"Oh, Brother Fan, I changed our A4 ......"

"Haven't you been blowing up the car?"

"The car is in my research institute, and today I came to do a computer simulation test."

"The result?"

"Didn't you just want to start here, haven't you had time to do it yet......"

Wang Rui, this kid always likes to sell off.

is different from the habit of the three scholars who often talk to themselves about the R&D process, this kid always likes to hold back his big moves. often can't see people for more than ten days and dozens of days, and reappearing again makes Li Fan guess what happened to him.

For this matter, Li Fanyu didn't know how many times he had abused him.

For the research and development of high-performance versions of some Audi cars, Wang Rui has been doing it for a long time. With the sufficient funds of the R&D center, he took 4 groups to throw money at it. Because domestic car performance modification is not allowed, the research and development conditions are very poor, and many of the materials and parts needed for the research and development of some high-performance versions need to be customized abroad.

Just said that it was the 3.0LV6 engine that was put on the A6 before the explosion, Li Fanyu remembered that this group of boys had applied for more than 6 million research and development funds, not to mention the things that needed to be used on the body, such as ceramic brake discs and carbon fiber custom parts.

smashed more than 70 million yuan before and after, and now he has finally made some achievements.

"Mizuko, you're finally useful!"

Looking at the relieved expression on Li Fanyu's face when he saw his dog learn to go to the toilet, Wang Rui poured a mouthful of old blood into his throat......

Now the R&D center now has quite complete simulation test equipment, which was considered to be too expensive for real vehicle testing and too long for the cycle. Anning specially introduced a complete set of PSAM data simulation system from Germany.

Wang Rui came over with the data package today to verify the performance parameters of the A4 high-performance version after the explosion.

Li Fanyu came to the data lab with the four of them, entered the data into the system with them, and started the test.

Today's main thing is to determine the power parameters, and Wang Rui has made countless modifications to the V6 engine before this, and the data package has been established very well. So it only took more than 40 minutes for a set of data to appear on the computer screen.

Seeing this set of bright and blind data, Liu Qing slapped excitedly: "Theoretical maximum output power, 350Ps, 245KW." Theoretical maximum torque, 480Nm. Hey, look good, Ruizi. Awesome my brother!"

In the past six months, in addition to cooperating with Brother Fan to develop new cars, all my efforts have been spent here. Hell knows what happened to me with that V6 engine!"

Looking at Wang Rui's face, Xu Fufang rubbed his head fiercely, making his already messy hairstyle more like a chicken nest.

But this made Wang Rui even more powerful.

But he does have the capital, and in the past four months, it is not an exaggeration to describe his R&D attitude.

In the power area alone, this product consumes a lot of heart.

He used the V63.0L engine previously used in the A6 to increase the material strength, carry out the press expansion cylinder, and add a turbo system.

But it's not just about adding a turbo, in order to increase the performance of the engine to a greater extent, trying to make the turbocharging system and the engine better combined, this product has been boldly designed with the determination to fight to the end.

The entire R&D process has undergone six major changes and more than 70 minor adjustments and upgrades.

The principle of the turbine system is to recover the hot exhaust gas emitted from the engine and put it into the cylinder to increase the air pressure in the cylinder. The specific process is to use the exhaust gas discharged from the engine, impact the turbine loaded in the exhaust system to make this part of the gas rotate at high speed for compression, and then force this part of the compressed and cooled gas back to the cylinder.

Since the power of the engine is directly proportional to the air intake, the increased air intake can increase the power of the engine.

The principle is simple, but to get the most out of the turbine and maximize the engine performance, there are many doorways here. There are big articles to be done in all parts of the whole work process.

Take the design Wang Rui has at hand, for example;

The engine cylinder exhaust port and supercharger intake are designed to be in close proximity to each other. In this way, when the turbine is working, the exhaust gas generated by the cylinder can be recovered as much as possible, so as to increase the pressure in the cylinder and increase the power.

The air inlet is also designed with a spiral-shaped non-mainstream shape, so that when the high-pressure gas compressed by the turbine enters the cylinder, a rolling air flow is formed, making the combustion in the cylinder more efficient and sufficient.

On this basis, this crazy man adds an intercooler to each group of cylinders, so that the high-pressure gas in the cylinder has a lower temperature, higher density, and more oxygen content, which further improves the compression ratio and makes the combustion in the cylinder more sufficient.

"Brother Fan, what's the matter, isn't it awesome?"

Wang Rui turned sideways, raised his chin at Li Fan, and waited for this thing to praise himself and bow down under his jeans.

In the more than a year since Zhengxin was established, Li Fanyu has been called the first person in domestic automobile research and development by some media. Therefore, the appreciation from the first person is undoubtedly a very satisfying thing for vanity.

But after waiting for a long time, he did not receive a response.

Seeing Li Fanyu staring at the computer screen with wide eyes and stunned, Wang Rui gently pushed him, "What's the matter, Brother Fan?

No,

The reason why Li Fanyu was flustered was because just now, a cold prompt from the system came to his head.

After nearly half a year, the system has once again accumulated enough R&D points - it's going to be upgraded!
