Automotive Black Technology Chapter 706: : Focus on technology!

Li Fanyu, who doesn't play by the rules, has no time to pay attention to the outside world at this time. As the New Year is approaching, he is already very busy.
Originally thinking of bringing the Range Rover off the production line in time for the prime sales period of the year before, Zhengxin had done everything well, but he made a famous mistake - when he went to the capital before, he was beaten by Kang Tong Cheng Gai was distracted, and he forgot to mention the matter of Land Rover's offline approval years ago.
Zhengxin submitted the information according to the normal approval process, but there has been news from the Ministry of Industry and Information Technology that the approval will not be available until at least the next year. They... are preparing to take a holiday for the New Year.
Although Zhengxin is a delicious snack, I can't delay people's New Year celebrations, so out of desperation, Land Rover's launch date can only be arranged later, after the Lunar New Year.
But the lack of approval does not mean that Land Rover's preparations will stall. The Land Rover branch originally felt that the listing before the year was too hasty. Now that the trip cannot be made due to objective reasons, Li Kai is actually very happy.
This way, he has more time to do publicity. This guy is already in contact with CCTV and is planning to let Zhengxin Land Rover Range Rover show up on the Spring Festival Gala.
In fact, on November 18, Zhengxin had already participated in CCTV's "Golden Resource Advertising Bidding Fair" and won the centenary event after the bell was rung.
Now that the bidding has ended, it will not be easy to insert advertisements. Li Kai had been pestering Li Fanyu for several days, but he couldn't bear it anymore, so Li Fanyu begged Ma for mercy to see if he could communicate with CCTV and add a few words.
If this matter had been done the year before last, it would have only been a matter of one sentence. why? Because Ma Rao was the director of Chunwang that year, but he was not the director this year, he had no choice but to show off his face and seek connections, and he was very passive.
This is one aspect.
On the other hand, Li Fanyu is working with the R&D center and Wang Yu’s team to cooperate with Guangqi’s R&D personnel to develop Tengshi’s first product.
Yes, as some outside speculation said - this is indeed a heavy-duty tractor.
It is true that heavy-duty tractors face a lot of problems in China. For example, the price is high and the machine is too large to adapt to some areas with high hills and poor road conditions.
But how could Li Fanyu fail to consider issues that outsiders can think of?
There are two kinds of people in this world; those who get around problems, and those who face problems head-on.
It just so happens that Li Fanyu is neither.
He is a slippery person. If the problem cannot be solved, he will go around it without hesitation. If this problem can be solved with a certain amount of effort, then he will definitely head on.
So in the face of the actual demand for heavy-duty tractors in China's agriculture and the environmental problems in the production areas, he decided to make up for it in terms of design.
In his view, the price of heavy-duty tractors is not a problem at all for Tengshi’s target customers.
It’s a joke. Why do you buy tractors worth two to three million dollars from abroad? As long as the performance is outstanding enough, are you afraid that the target market will not accept it?
What market does heavy-duty tractors face?
It is a large farm or forest farm. Those who can engage in this kind of business are either agricultural enterprises or government pilots, or they are individuals or equipment rental companies that specialize in agricultural production solutions.
Although heavy-duty tractors themselves are costly, their efficiency is there!
No matter how high the cost is, as long as the efficiency can overwhelm low-level production machinery or even lower-efficiency labor, then this is not a problem for those who can figure it out.
Faced with the complex terrain of domestic agricultural production areas, Li Fanyu is even more aware of it.
The target market for heavy-duty tractors is mainly large farms in agricultural production areas in Mongolia and the three northeastern provinces. The terrain in these areas is relatively flat. In fact, due to terrain restrictions, it is much better than the mountainous and hilly areas in Sichuan and Shaanxi.
But in order to gain a larger market, he decided to start with design to solve the problem of heavy tractors being restricted by individual terrains.
The first is the engine and transmission system.
With B-01 design experience, he has already accumulated sufficient experience. To adapt to the traction required for various types of towed plowing and harvesting, you must first have enough horsepower and low enough revolutions to obtain large torque output.
At this point, the essence of a tractor is no different than a tank chassis. This is why during World War II, Germany, which was not allowed to produce heavy weapons and equipment after being sanctioned, vigorously developed tractor factories.
The principle is the same. If you have accumulated enough technology, you can easily convert a tractor into a tank chassis without much effort, add a turret, and drive directly to the front line.
So in response to this, he designed an engine code-named TS-L609 - TS stands for Tengshi, L stands for inline, 6 stands for 6 cylinders, and 9 stands for displacement!
After all, tractors are agricultural machinery, so for cost reasons, Li Fanyu did not dare to use X aluminum alloy as the material of TS-L609. But having design expertise does not prevent him from turning this engine into a monster that beats existing six-cylinder diesel engines!
Like the B-01, this engine is equipped with a high-pressure common rail, a shared oil supply tank and surrounding water cooling technology.
After all, tractor engines are different from tank engines. Between military and civilian use, fuel consumption must be taken into consideration. For tanks, it is necessary to save some diesel fuel every 100 kilometers without delaying the overall combat effect. In order to ensure reliability and logistical maintenance and repair considerations, the engine cannot be made too complex and too many technologies should be applied to achieve relatively weak effects. of fuel economy.
But tractors are different. You must know that this thing requires a long time to work, and fuel consumption needs to be calculated in the production cost, which has become an important indicator when customers choose a certain tractor.
So on the TS-L609, Li Fanyu combined the high-voltage common rail system with HC-SCR technology.
What is this toy for?
Optimize combustion!
The principle of this system is very complex. To put it simply, the NOx gas emitted after the diesel engine is burned is reduced to NOx through ethylene, propylene, butene and propane as catalysts, and then the high-pressure common rail is used to control the fuel injection amount. and timing are precisely controlled, and the restored NO gas is injected back into the engine cylinder for secondary combustion.
This not only enhances the combustion efficiency of the engine, but also reduces harmful gas particles in the exhaust gas and improves emission standards.
This principle is like a dog eating a meal of meat, but seeing that there are still meat stars in the pancake...
Ahem, that’s so disgusting. Let’s change the metaphor...
This is a bit like smoking. When you take the first puff and exhale, you find that the smoke is still strong, so you inhale the exhaled smoke back to absorb the tar and nicotine in the waste again.
It means the same thing, but smoking in this way will cause more harm to people's respiratory system.
The engine uses this technology to make combustion more complete and more environmentally friendly!
