Rebirth of the 80s New Farmer

Chapter 2256 is as stupid as you
Variable valve engine is also called VVT engine.

It is to adjust the intake and exhaust volume and timing and change the valve overlap angle by controlling the opening angle of the intake valve to advance and delay under specific engine operating conditions, so as to increase the intake charge and efficiency.Better organize the intake vortex, adjust the cylinder explosion pressure and residual exhaust gas volume, to improve the comprehensive performance of the engine power, torque, emission, fuel economy, comfort, etc., so as to solve the various performances of the traditional fixed valve timing engine Technical contradictions that restrict each other between indicators.

This technology started in the 60s and the early 80s, and was first used by Italian manufacturer Alfa Romeo.

But it was Toyota who really promoted this technology. In [-], Toyota promoted this technology all over the world.

During this period, the application of this technology is still in the initial stage. Whether it is a hydraulic helical spline phaser, a hydraulic vane phaser or a star rotor phaser, they are all initial products, so the response speed of the VVT ​​system is average.

Since Toyota began to apply it in their cars, Nanwan is also researching this technology, but what Nanwan researches is not the VVT ​​technology using the appealing three phasers, but a one-step development of the mid-mounted hydraulic VVT system.

Because the mid-mounted OCV is installed inside the rotor of the phaser, the OCV is close to the oil chamber inside the phaser, so the oil pressure loss in the oil passage is small during the working process, and the response speed is higher than that of the traditional VVT system.

Wan Feng only knew a little about this technology. In the latter part of the previous life, around [-], foreign manufacturers began to use this technology on a large scale.

Stores that sell cars are always bragging and talking about it.

And the car owners who buy and install this kind of engine are still full of dissatisfaction with half a bottle, and use this to belittle those car owners who are not equipped with this kind of engine. If you ask them, they still can't explain clearly.

Wan Feng, who also wanted to buy a car around [-], learned about the sacredness of this mid-mounted hydraulic VVT engine on the Internet.

It's a pity that although he read a lot of articles introducing this kind of engine, he didn't understand it very well.

What he explained to Nobu Asada, Gun Fulai and others in this life is just a mechanical retelling, and he can only tell 80.00% of the content, and the rest needs to be made up by Asada Nobu, Gun Fulai and others.

Nanwan Engine has mainly developed inline four-cylinder engines in recent years. In fact, it has made various improvements in the two basic NW478 and NW479 engines.

But the six-cylinder engine, which was formally approved and developed last year, is completely different from before.

The cylinder bore is 82 mm, and there are two types of L6 and V6 in form, which is simply a new engine developed.

When the project was approved last year, Wan Feng estimated that it would take three years. I don’t know if Asada Shin’s team can win it.

If it can be installed in 479, then it can take over the executive car with [-] engine.

There is also a four-wheel drive.

As an executive car, Wan Feng still believes that four-wheel drive is a guarantee, although it may not be useful in normal times.

Because of the four-wheel drive, this car looks tall, so maybe he is embarrassed to ask for more money.

After laying the foundation and maintaining the relationship in the early stage, it is inevitable to increase the price in the later stage. The public money should not be wasted, or it might be corrupt...

I didn't say that, I didn't even think about it.

Still maintain a high level of trust in someone in the government.

Asada Nobukun Fulai and the Tibetan military officer, the three giants of the Nanwan gasoline generator, all came and reported the development progress of the new engine to Wan Feng.

The two forms of the new six-cylinder engine are almost in a state of simultaneous development.

These three people were divided into two groups. Nobu Asada and Gun Fu came to study V6, and the Tibetan military officer team developed L6. However, the two teams were not completely independent, and they sometimes mixed with each other to tackle key problems.

Relatively speaking, the research and development progress of the inline 6-cylinder engine of Tibetan military officers can be faster. After all, Nanwan has been playing with inline 4-cylinder engines for these years, and the accumulation of experience is still very important.

As for the V-type engine, Nanwan is completely blank. Although the principles are similar, the gap in details is great.

The Tibetan military officer said that the L6 engine may not be able to be used in three years, but Asada Nobu is cautious and pessimistic about the progress of the V6 engine.

What Wan Feng can do is to try his best to reassure them not to worry, the engine is not a problem that can be solved by slapping the ass or forehead, it is a typical slow work and careful work.

Of course, there is also the promise of asking money for money and people for people. His task is to solve all the worries of these researchers. You can focus all your energy on research and development, and I will solve other problems.

Now Wan Feng has some ideas about these two engines. The installation of the inline six-cylinder engine means that the Tibetan military officer means that a prototype may be produced by the end of this year. After a year of various tests next year, if everything goes well, it can basically be finalized by the end of the year.

The V6 may not be finalized until the end of [-].

Wan Feng was not in a hurry when he was confident in his mind. He couldn't drink the hot soup in a hurry, and it was better to let nature take its course.

Receiving these leaders today made him a little mentally exhausted. He decided to go home early to enjoy family fun and relax his tired nerves.

When I got home, I unexpectedly found that Luan Feng was also at home.

"Hey! Why did you come back so early today?"

Luan Feng gave Wan Feng a white look: "You can come back so early, I won't come back earlier."

"This is not good. As the CEO of an enterprise, you have to set an example and don't come back early every now and then. This will have a bad influence on the employees." Wan Feng said in a serious manner, with correct words.

Luan Feng looked at him sullenly: "He's an official after all, with this official accent, those who don't know think he is some kind of good food."

Zhang Xuan just pursed her lips and smiled and participated in the bickering between the two, concentrating on teaching her daughter to read.

"My daughter is so good, come and kiss her."

Wan Yu, who was sitting, stretched out her small face, let Wan Feng kiss it, and then touched her own face with her small hand, apparently pricked by a beard.

"Oh! What are you doing learning this? Isn't it bullshit for my daughter to learn this when she is only one year old? Don't tire my daughter's head."

It's true that Wan Yu learned this early. What's the use of this without memory?

On the contrary, the son should learn these things now, but the son...

"Where's the son?"

Wan Feng asked Luan Feng.

"Son? You were still below the ducks with a stick just now!"

"Can you do it? Are you going to make your son as stupid as you in the future?"

Luan Feng became angry: "Who are you calling stupid? Say it again."

"Cut! Don't you admit that you are stupid? I ask you a question and you can answer it, so I won't say you are stupid."

Luan Feng immediately felt guilty: "Is it okay if you don't answer?"

She really didn't have the confidence to answer Wan Feng's question.
