Zhengxin Volkswagen Hongguang this car, the ...... Or Wuling Hongguang,

In fact, there are only two power versions on the drawings, one is equipped with a P-TEC, 1.2L displacement engine. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 The info model is equipped with a P-TECDVVT engine with a displacement of 1.5 liters.

In the previous time and space, the 1.2L engine of Wuling Hongguang was actually installed on the basic version in order to reduce the price. The main market is actually the 1.5-liter P-TECDVVT engine version.

And as far as Li Fanyu knows, the best model sold by Hongguang in that time and space is this version. As a small displacement MVP in itself, the 1.5L engine with DVVT technology is fuel-efficient enough. Therefore, out of the principle of good R&D and good manufacturing, he did not exchange the 1.2L engine version from the space.

You know, this car is to meet a variety of commercial household functions.

Although the small displacement is fuel-efficient, for Hongguang, which is applicable in third- and fourth-tier cities and towns, it is obviously not kind to make a model that pulls heavy objects and roars in order to lower the price.

In the drawings delivered to the R&D center, he marked the DVVT engine as a focus for development.

Although it is a joint production, according to Li Fanyu's idea, the engine must be manufactured and supplied by Zhengxin Power Company. Even if there is a controlling stake in those 12 car companies, people's hearts are unpredictable after all. In order to ensure that these car companies can obey Zhengxin, they must master the core technology in their own hands for at least the next five years.

As the saying goes, the heart of defense is indispensable.

Don't look at Hongguang is a micro-face that is not amazing, but in this car, it is equipped with a technology that can be called an incredible, for the automobile industry in this time and space.

That's DVVT.

Many people don't know what this DVVT is, but in fact, this thing adds a set of accessories to the engine.

What is this accessory for?

Help the engine breathe!

To explain this matter clearly, we have to start with VVT technology.

The working principle of the engine, to put it bluntly, is that after the gasoline enters the cylinder block and is compressed by the piston, the air put in the mixed valve is ignited and burned, and the heat energy is generated to drive the piston. The piston then converts the heat energy into potential energy and transmits it to the engine crankshaft to generate power.

This way of energy transformation can be said to be one of the greatest inventions of mankind.

But with the popularity of engines, with the rise in oil prices and the gradual deterioration of the environment. On the basis of this set of principles, people continue to optimize and transform the engine, trying to make the engine more economical, more fierce and more durable......

Thus, VVT technology was born.

This technology, to put it bluntly, is to adjust the air intake volume of the engine and the angle of valve opening and closing time according to the operating condition of the engine through the electronic control unit. The air intake is optimally improved and the combustion efficiency is improved.

And improving combustion efficiency means more fuel saving, that is, more fuel saving.

However, after the VVT technology was put into use, it was found that although this technology can save fuel in the engine, some disadvantages also came into being - that is, as the power-to-lift ratio increases, the engine speed and torque are reduced to a certain extent.

Therefore, after summarizing the shortcomings of VVT technology, DVVT technology came into being.

The DVVT engine can be said to be a continuation of the VVT engine, but the blue is better than the blue. By utilizing a relatively simple hydraulic cam system, the DVVT not only improves the combustion ratio, but also overcomes the shortcomings of the lack of speed and torque caused by constantly adjusting the valves.

This effect is achieved because the VVT engine has been controlled by the electronic unit, so only the intake valves can be adjusted. The DVVT engine, on the other hand, uses a hydraulic cam system to control both the intake and exhaust valves. The DVVT engine has realized the simultaneous adjustment of the intake and exhaust valves, and has the characteristics of low revolution, high torque, high speed and high power.

It looks complicated, but it's actually the same as human breathing.

VVT only regulates "breathing", but DVVT regulates "breathing" at the same time!

This control method is technically known as "dual continuous variable valve timing". It can be said that in the time and space that Li Fanyu was in before, this was the most advanced situation in the valve variable system.

However, in this time and space, this technology does not exist!

Those Japanese car companies that are famous all over the world for their fuel efficiency are still struggling with VVT!

That's why Li Fanyu was able to attach so much importance to Hongguang's model.

In this time and space, it is said that Japanese cars are fuel-efficient. But Li Fanyu believes that after mastering DVVT technology, Zhengxin will have the capital to compete with Japanese engines in the future!

After Liu Qing saw the Hongguang P-TECDVVT engine structure passed by Li Fanyu, he immediately put away his previous reluctant thoughts. After understanding the principle of valve adjustment of the engine, he could no longer resist the shock in his heart.

In his opinion, this is simply a revolutionary technology that can set off a round of automobile engines!

Not only him, but also the engineers in the R&D center were also stunned. They really can't imagine how majestic Zhengxin will be in the automobile market with this technology!

What is the current automotive industry comparative?

Technology!

What's the point of technology?

Make consumers feel more comfortable, safer, and more affordable.

In China, where oil prices continue to rise, whoever masters a more fuel-efficient and more powerful engine undoubtedly has mastered immeasurable competitiveness!

In the face of everyone's excitement, Li Fan was foolish.

Although this product is not in a proper shape and is giggling in everything, he has done his best for his career.

One step counts as three steps to lift him, and he doesn't have the kind of wisdom that is similar to a demon. But it is no exaggeration to say that every model that is being believed. It's not just because his head has been hot for a long time.

Behind these models, he carries the layout of his supreme step by step for Zhengxin!

Hongguang is such a model.

Well, in the words of a tall and faint pretence, this is a strategic model.

Motivate the R&D team and let them step up after completing the R&D. Li Fanyu came to Zhengxin Power Company, and after inspecting the ongoing production system upgrade, he called Pan Qiang and Sun Guoyi together.

After instructing the two to pay close attention to the system upgrade, they must ensure that the existing models are supplied to the market demand while upgrading, and ensure that the production quality is not affected by the upgrade, and then issued a branch task.

That is, the existing technical engineers are drawn to form an expert working group. Go to the 12 car companies that have formed an alliance with Zhengxin to help them adjust and integrate their production lines.

For this task, even Pan Qiang, who completed various tasks as a soldier, couldn't help but collapse his face.

"Chairman Li, now the company's technical engineers, are all busy with system upgrades on the production line, and they really can't be deployed!"

Sun Guoyi's face with a national character also turned into an embarrassed face, "Yes, chairman, you can't split a person into two pieces!"

Seeing these two people complaining, Li Fanyu tilted his head, "Don't you still have a group of treasures, how can you say that there is no one?"

Baby?

What baby?

Seeing the puzzled faces of the two, Li Fan smiled foolishly: "Those high-achieving students of Western University of Technology have been cultivating at the grassroots level for many months. Shouldn't you throw it up for me?"

Sun Guoyi slapped his thigh, "No, Ao Li Dong, this is not good!"

This big brother shook his head like a rattle, and those would-be engineers who had mastered production technology and had a lot of theoretical knowledge in their minds were now regarded by Sun Guoyi as the number one killer of power companies!

I didn't feel much at first, but after this period of training, these high-achieving students have played a very important role in the power company.

Now Li Fanyu is begging for it, which is almost equivalent to digging Sun Guoyi's heart!
