The Volkswagen branch is staffed by Zhengxin’s sales department. Many of the company’s middle and senior management have experienced the marketing work of several models of the Audi brand. After being baptized by Hongguang, the national sacred car, Volkswagen's grassroots personnel are already familiar with the marketing of new models.
Although everyone in the company is extremely busy, everything is still in order. All this is a guarantee to support the fighter's continued sales.
After inspecting the branch, Li Fanyu felt relieved.
Seeing that he didn’t have to worry about anything, this guy breathed a sigh of relief and said, "Hey, it’s better to be at home, so you don’t have to worry!"
But there are also things that don’t make you worry.
At this time, it has been three days since the fighter went offline.
According to the sales data submitted by Volkswagen, among the two power versions of diesel and gasoline, the gasoline engine versions with three displacements of 1.5T, 1.8T, and 2.0T account for almost all sales.
The combined sales of the two diesel engine versions did not exceed 100 units.
Li Fanyu felt deeply helpless about this situation.
In fact, normally speaking, diesel engine emissions are more in line with environmental standards and requirements under the general trend of increasingly serious environmental pollution.
And because the compression ratio of a diesel engine is high, its thermal efficiency is about 30% higher than that of a gasoline engine at a similar displacement. This means better fuel economy for diesel engines. , from the perspective of saving energy and reducing fuel costs, diesel engine vehicles should have more advantages.
But it is very helpless. The diesel engine makes relatively loud noise when working, which has a certain impact on the riding experience in the car. Moreover, the quality of domestic diesel oil is not high, which has led to the high failure rate of diesel-powered cars in the Chinese automobile market.
During the period when the automobile market was developing rapidly, diesel vehicles gave consumers a poor impression. In addition, the country had previously invested most of its diesel resources in industrial development, and policies advocated the use of diesel vehicles in the civilian automobile market. Gasoline is the main fuel, which means that everything on the market is powered by gasoline.
Even now, the diesel version of the Fighter is shared with the two engines of the F150. It adopts turbocharging, intercooling and direct injection technology. In order to reduce the large amount of harmful particulate matter emitted after diesel combustion, it is equipped with two advanced technologies: exhaust catalytic conversion and particle trap. The emission standards have reached Euro IV level, but they are still not favored by the market.
After returning to China, few people paid the bill, which made Li Fanyu, who originally relied on fighters to test the waters of diesel power, feel deeply hurt and heartbroken.
Nowadays, the use of diesel engines is being promoted in Europe, trying to improve the increasingly harsh environment with the advantages of diesel power, long life, good power performance, and half the greenhouse effect compared to gasoline engines.
In this context, even high-end cars that always pursue a good ride experience and require quietness generally use diesel engines.
But now it seems that there is still a long way to go before diesel engines can flourish in China.
With this slight pain in his balls, Li Fanyu returned to the industrial park.
Now that the research and development work on the fighter has ended, each team has started working on their own projects.
At present, Zhengxin's R&D scale is large, and the group has set up incentive policies for various new technologies, so each team has its own R&D topics.
Among these topics are the ECU that was originally jointly developed by three top students, Wang Rui’s high-performance modification project, and other improvement projects similar to various body parts.
Beyond these, of course. There are also commercial projects such as future automobiles jointly carried out by Zhengxin and Baiwei Company.
Seeing Li Fanyu come to the R&D laboratory with a melancholy look on his face, the three top students and Wang Rui gathered around him with playful smiles.
Liu Qing: "Hey! Isn't this Brother Fan? Why did he just impress the beautiful anchor and still look unhappy?"
Xu Fufang: "I don't seem to be very interested. What's going on? Did you let someone cook it?"
Wang Yu: "The guilt after destroying flowers with ruthless hands."
Wang Rui giggled.
Nowadays, Li Fanyu is as popular on the Internet as some well-known anchors. He made Celluloid, the goddess in the eyes of many otakus, squat and sing about conquest. This domineering attitude also convinced a large number of netizens. It's because this matter is being discussed fiercely on the Internet right now, that's why the top three students made such a joke.
Being made a joke by these three idiots, Li Fanyu instantly turned into a dog-like face: "Go away! What is this? Am I guilty? I let her squat down and sing about conquest. It's all my fault! Otherwise, hum. Hum..."
Xu Fufang: "What else?"
Liu Qing: "Otherwise, you want to bang her? It would be a pity if I wiped you and drained the water. Although Celluloid is a little crazy, there is nothing to say about her figure and appearance!"
Wang Yu hit the nail on the head: "A waste of opportunity."
Wang Rui continued to giggle.
"Go away! Why are you so mean?" Li Fanyu waved his hand and immediately felt something was wrong, "Hey? Why are the four of you here and slacking off? Your wages will be deducted!"
"You, how can you accuse someone of innocence out of thin air!"
"Yes, yes, we are in the R&D center, but how can we call it laziness? This is called taking a nap!"
"Correct answer!"
Wang Rui is still smiling,
Wang Rui, who saw Li Fanyu staring and giggling the whole time, finally said: "Brother Fan, what are you doing this for?"
Li Fanyu waved his hand, "Don't mention it!"
After pondering for a moment, he told the story about the diesel version of the Fighter that was going off the charts.
Hearing this, Xu Fufang and Wang Yu felt a little uncomfortable.
The two of them led the research and development of the F150 diesel engine. After Li Fanyu returned to China to work on Hongguang, they worked hard in the United States for a long time before solving the technical difficulties. The emission standards in the United States are relatively high, so the audit and testing alone went through more than ten times. Just looking at this aspect, the hard work that went into it is self-evident.
Xu Fufang and Wang Yu have participated in the research and development of these engines owned by Zhengxin. But when it comes to the F150, the turbocharged engine named Hercules by Li Fanyu is the one that the two of them put the most thought into.
The technical requirements of diesel engines are actually no lower than those of gasoline engines; diesel engines have 4 nozzles per cylinder, and they need to be closed 4 times each time the drive shaft rotates. The time accuracy required is much higher than that of gasoline engines.
After putting in so much hardship, the two naturally had higher expectations for the diesel version of the fighter.
"Hey, there is nothing we can do about it." Seeing his friend depressed, Wang Rui broke the silence: "Actually, there is nothing we can do about it. Our domestic crude oil is all high-sulfur oil. Even after refining, diesel oil The high-pressure common-rail electronic injection used in the engine also has a lot of impurities, the nozzle is prone to corrosion and the service life of the oil filter is greatly reduced, so few people will 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 is actually pretty good, except for carbon deposits in the engine and clogged filters. , compared with foreign countries, the difference is nothing more than replacement every 80,000 kilometers and replacement every 100,000 kilometers. This is not the main factor why diesel engines cannot develop in our country. ”
"What's the reason? Is it because the diesel engine has high torque but slow acceleration?"
"Of course not! With the extremely congested roads in China, isn't it just right that diesel engines are fuel-efficient and slow to pick up speed?"
"What's that for?"
"Concept!"
Xu Fufang curled his lips and said.
