The Volkswagen branch is a staff drawn from Zhengxin's sales department, and many of the company's middle and senior management have experienced the marketing of several models of the Audi brand. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 After the baptism of the national god car Hongguang, the grassroots personnel of Volkswagen are also familiar with the marketing of new models.

Although the company is busy in the back of the head, everything is still in order. All this is a guarantee to support the continued hot sales of fighters.

After inspecting the branch, Li Fanyu was relieved.

Seeing that he didn't have to worry about anything, this cargo breathed a sigh of relief, "Hey, it's better to be at home, worry-free!"

But there are also things that don't worry.

At this time, it has been three days since the fighter went offline.

According to the sales reported by Volkswagen, among the two diesel-gasoline versions, the 1.5T, 1.8T, and 2.0T gasoline engine versions account for almost all of the sales proportion.

Neither of the two diesel-engine versions combined sold more than 100 units.

For this situation, Li Fanyu felt helpless.

In fact, according to the normal situation, the emissions of diesel engines are more in line with the standards and requirements of environmental protection under the general trend of increasingly serious environmental pollution.

And because the compression ratio of diesel engines is relatively high, its thermal efficiency is about 30% higher than that of gasoline engines under similar displacements. This means that the diesel engine has better fuel economy. From the point of view of saving energy and reducing fuel costs, diesel engine cars should have more advantages.

But it is very helpless, the noise of the diesel engine is relatively loud when it is working, which has a certain impact on the riding experience in the car. Moreover, the domestic diesel oil quality is not high, resulting in a high failure rate of diesel-powered versions of cars in the previous Chinese automobile market.

During the period when the automobile market developed rapidly, the perception of diesel cars to consumers was too poor, coupled with the fact that the country had invested most of the diesel resources in industrial development, and advocated the use of gasoline as the main fuel in the civilian automobile market in terms of policy, which led to the fact that all the water on the market was gasoline power.

Even now, the diesel version of the Gladiator is shared with both engines of the F150. It adopts turbocharging, intercooling, and direct injection technology. In order to reduce the harmful particulate matter emitted by a large number of diesel after combustion, it is equipped with two advanced technologies: exhaust catalytic conversion and particle trap, and the emission standards have reached Euro IV, which is still not favored by the market.

returned to China, stunned that few people paid for it, which made Li Fanyu, who had saved and relied on the fighter to test the water with diesel power, feel deeply hurt and pierced.

Now Europe is promoting the use of diesel engines, trying to improve the increasingly harsh environment with the advantages of diesel power with high power, long life, good power performance, and half the greenhouse effect compared with gasoline engines.

In this context, even high-end sedans that have always pursued a good riding experience and require silence generally use diesel engines.

But now it seems that if the diesel engine wants to develop in China, there is still a long way to go.

With this slight egg pain, Li Fanyu returned to the industrial park.

Now that the R&D work of the fighter has ended, the teams have started their own projects again.

At present, Zhengxin's R&D scale is large, coupled with the incentive policies set up by the group for various new technologies, so each team has its own R&D topics in hand.

Among these topics, there are ECUs such as the original joint efforts of Sanxueba, high-performance modification projects like Wang Rui, and improvement projects similar to various body parts.

Beyond these, of course. There are also commercial projects such as Future Automobile, which are jointly carried out by Zhengxin and Baiwei.

Seeing Li Fanyu coming to the R&D laboratory with a melancholy face, Sanxueba and Wang Rui came forward with hippie smiles.

Liu Qing: "Yo! Isn't this Brother Fan Lao Tie? Why did you just convince the beautiful anchor and still look sullen?"

Xu Fufang: "Lao Tie doesn't look very interested, what's going on, let people cook it?"

Wang Yu: "The guilt after the spicy hand destroys the flowers." ”

Wang Rui smirked.

Now Li Fanyu's popularity on the Internet is no worse than that of some well-known anchors, and let the goddess celluloid in the minds of many otaku squat on the ground to sing and conquer, which is also impressed by a large number of netizens. It's because this matter is now being discussed on the Internet that it's very fierce, so there is a joke from the three scholars.

Being made a joke by these three goods, Li Fanyu instantly turned into a dog face: "! What is this? I feel guilty? Let her squat down and sing the conquest is the master, I will release the water! Otherwise, hum ......"

Xu Fufang: "Otherwise, what?"

Liu Qing: "Otherwise, I want to knock her, it's a pity that I wiped your water, although celluloid is a little crazy, but I don't have to say anything about my figure!"

Wang Yu hit the nail on the head: "Waste of opportunity." ”

Wang Rui continued to giggle.

", why are you so cheap?" Li Fanyu waved his hand, and then felt wrong, "Hey, why are the four of you all here, lazy, you guys, deduct your salary, deduct your salary!"

"You person, how can you smear people's innocence out of thin air!"

"It's extreme, it's extreme, we're in the R&D center, but it's okay, how can we call it lazy?

"Correct solution!"

Wang Rui still smirked,

Seeing Li Fan's foolish eyes, Wang Rui, who was smirking at the whole scene, finally spoke: "Brother Fan, what are you doing here?"

Li Fanyu waved his hand, "Don't mention it!"

After a moment of silence, he told the story of the diesel version of the fighter selling on the street.

Hearing this, Xu Fufang and Wang Yu were also a little uncomfortable in their hearts.

The F150 diesel engine was developed by the two of them, and the two fought for a long time in the United States after Li Fanyu returned to China to engage in Hongguang before solving the technical difficulties. The U.S. has high emission standards, so it has gone through more than 10 audits alone. From this aspect alone, the hard work put into it speaks for itself.

Zhengxin's engines, Xu Fufang and Wang Yu have participated in the research and development. But to say that the F150 is equipped with a turbocharged engine named Hercules by Li Fanyu, but the two of them have the most intentions.

The technical requirements of diesel engines are not lower than those of gasoline engines, and diesel engines have 4 nozzles per cylinder, and each time the drive shaft rotates, it needs to be closed 4 times, which requires time accuracy, but it is much higher than that of gasoline engines.

After paying so much hardship, the two naturally have higher expectations for the diesel version of the fighter.

"Well, there's no way around it. Seeing that his friends were depressed, Wang Rui broke the silence: "In fact, this is also a helpless thing, our domestic crude oil is high-sulfur oil, even after refining, the high-pressure common rail EFI used in the diesel engine can not withstand it." There are also many impurities, the nozzle is easy to corrode and deposition carbon, and the service life of the oil filter is greatly reduced. If you are in trouble, there will be fewer people who will naturally accept it. ”

After hearing this, Xu Fufang frowned and said, "What Wang Rui said makes sense, but that was a few years ago. Now our domestic diesel oil products are actually okay, to say that the engine carbon deposition and filter blockage, compared with foreign countries, it is nothing more than the difference between 80,000 kilometers and 100,000 kilometers. This is not at all the main factor that diesel engines cannot develop in our country. ”

"What's the reason for that? Could it be that the diesel engine has a lot of torque but slow acceleration?"

"Of course not! In the current traffic jam in China, isn't it just right that the diesel engine is fuel-efficient and the acceleration is not fast?"

"What's that?"

"Concept!"

Xu Fufang pursed his lips and said.
