Li Fanyu, who doesn't play cards according to the routine, has no time to pay attention to the voices of the outside world at this time, but he is already busy when the New Year is approaching. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

I wanted to catch up with the sales prime period of the previous year, and all aspects of Zhengxin were well operated, but he made a well-known mistake - when he went to the capital before, he was diverted by Kang Tongcheng, and he forgot to say that the Land Rover was approved off the assembly line before the year.

Zhengxin submitted the information according to the normal approval process, but the Ministry of Industry and Information Technology has already heard the news that the approval will not come down until at least a year later, and they ...... Preparing for the New Year's holiday,

Although Zhengxin is a fast fragrant dumpling, but the king of heaven Lao Tzu can not delay the New Year, so in desperation, the listing date of Land Rover can only be arranged later, adjusted to the Lunar New Year.

However, the lack of approval does not mean that Land Rover's preparations will be stagnant, and the Land Rover branch has felt that the listing was too hasty before the year. Now that he can't make the trip due to objective reasons, Li Kai is quite happy.

That way, he has more time to do publicity. This product is now in contact with CCTV, ready to let Zhengxin Land Rover Range Rover, want to show its face in the Spring Festival Gala.

In fact, on November 18, Zhengxin had already participated in CCTV's "Gold Resources Advertising Bidding Conference", and won the centennial link of the enterprise after ringing the bell.

Now that the tender has ended, it is not easy to insert advertisements into it. Li Kai pestered Li Fanyu for several days, but he couldn't be patient, so Li Fanyu begged Ma Rao to see if he could communicate with CCTV and add a little more.

If this matter had been placed the year before last, it would have been a matter of one sentence. Why? Because Ma Rao was the chief director of Chunwang that year, but it wasn't him this year, so he had to sell his face for a relationship, and he was very passive.

That's one thing.

On the other hand, Li Fanyu is working with the R&D center and Wang Yu's team to unite the R&D personnel of Guangqi to develop the first product of Tengshi.

That's right, as some outside speculation says - this is indeed a heavy tractor.

Admittedly, heavy tractors have a whole bunch of problems in China. For example, the price is high, and the machine is too large to adapt to some highland, hilly and poor road conditions.

But a question that outsiders can think of, how could Li Fanyu not think about it?

There are two kinds of people in this world: those who face problems and bypass them, and those who face problems head-on.

Coincidentally, Li Fanyu is not.

He's the kind of guy who is slippery. If this problem cannot be solved, he will not hesitate to bypass it. If this problem can be solved with a certain amount of effort, then he will definitely rise head-on.

Therefore, in the face of the actual demand for heavy-duty tractors in China's agriculture and the environmental problems of the production area, he decided to make up for it from the design aspect.

In his opinion, the price of heavy-duty tractors is not a problem at all for the target customers that Tengshi faces.

Joke, why are two or three million foreign tractors bought, as long as they are outstanding enough in performance, afraid that the target market will not accept them?

What market are heavy tractors facing?

It is a large farm and forestry farm, and the one that can engage in this kind of business is either an agricultural enterprise or a government pilot, or an individual or equipment rental company that specializes in agricultural production solutions.

Heavy-duty tractors are expensive in themselves, but efficiency is there!

No matter how high the cost is, as long as it can overwhelm the low-level production machinery in terms of efficiency, or the labor with lower efficiency, then this is not a problem for those who can calculate the account.

In the face of the complex topography of domestic agricultural production areas, Li Fanyu is even more aware of it.

The target market for heavy-duty tractors is mainly to the agricultural production areas of Mongolia and the three eastern provinces. The terrain in these areas is relatively flat, in fact, the factors limited by the terrain are much better than the mountainous and hilly areas of Sichuan and Shaanxi.

But in order to gain access to a larger market, he decided to start with the design and solve the problem that heavy tractors were limited by individual terrain.

The first is the engine, and the drivetrain.

With the experience of designing the B-01, he already has a full accumulation. To accommodate the traction required for all kinds of towing ploughs and harvesting, you first need to have enough horsepower and enough low speed to get a high torque output.

At this point, the essence of a tractor is no different from a tank chassis. This is also why during World War II, Germany, which was not allowed to produce heavy weapons and equipment after being sanctioned, vigorously developed tractor factories.

The reason is the same, the accumulation of technology is enough, and it does not take much effort, you can directly change the tractor into a tank chassis, add a top-mounted turret, and you can directly drive to the front line.

So in response to this, he designed an engine codenamed TS-L609 - TS stands for Tengshi, L stands for inline, 6 stands for 6 cylinders, and 9 stands for displacement!

After all, the tractor is an agricultural machinery, so for the sake of cost, Li Fanyu did not dare to use X aluminum alloy as the material of TS-L609. But having a design expertise doesn't prevent him from turning this engine into a monster that beats the existing six-cylinder diesel engine!

Like the B-01, this engine is equipped with a high-pressure common rail, shared oil supply groove and surround water cooling technology.

After all, tractor engines are different from tank engines, and fuel consumption must be taken into account between military and civilian use. In the case of tanks, a little diesel fuel is saved every 100 kilometers without delaying the overall combat effect, and in order to ensure reliability and logistical maintenance and repair considerations, the engine cannot be made too complicated and too many technologies can be applied in order to achieve relatively weak fuel efficiency.

But the tractor is different, you must know that this game should have to work for a long time, fuel consumption needs to be calculated in the production cost, become an important indicator when customers choose a tractor.

Therefore, on the TS-L609, Li Fanyu combined the high-pressure common rail system with HC-SCR technology.

What is this for?

Optimize combustion!

The principle of this system is very complicated, to put it bluntly, the NOx gas discharged after the combustion of the diesel engine is reduced to NO through B, C, BUTYLENE and propane as catalysts, and then the high-pressure common rail is used to accurately control the amount of fuel injection and timing, and the NO gas is also reduced and sprayed back into the engine cylinder for secondary combustion.

This not only enhances the combustion efficiency of the engine, but also reduces the harmful gas particles in the exhaust gas and improves the emission standard.

This principle is like a dog eating a meal of meat, but seeing that there is still meat in the poop that is pulled out.......

Ahem, it's disgusting, to put it another way......

It's a bit like a person smoking a cigarette, and when he takes the first puff and exhales, he finds that the cigarette is still strong, so he inhales the exhaled smoke back and re-absorbs the tar and nicotine in the waste inside.

It means one thing, but smoking in this way will aggravate the damage to the human respiratory system.

And this technology for the engine is to make the combustion more adequate and more environmentally friendly!
