The motherland is booming, and all walks of life need precision processing, so they can come to their own side to seek support.

Hearing Qin Guan's words, Zhang Gong kept nodding. Thank you very much!

For Institute 114, it needs precise processing technology to overcome the difficulties of flat slot radar antenna. However, if Institute 114 introduces corresponding processing tools, it will cause great waste, because they produce radar equipment, mainly produce electronic products, and require little precise processing. If one radar is directly introduced, the output will be dozens of radars that year, What a waste.

If you find a special place to process it, it is certainly the best.

At the same time, in China, there are no people who can operate five axis linkage CNC machine tools. Even Sandra can only master it after research and reflection. Marriage is more beneficial to the country. He Ri Bala can serve the country.

He Ri Bala didn't lose anything. He married a foreign daughter-in-law. Look at the figure and milk of others. Tut Tut, he RI Bala must be very happy to say.

At present, the domestic CNC machine tool industry still has not developed. There is no way. It can only be achieved through a process. There are very few talents, including those who operate machine tools. Otherwise, they won't make up their mind on Sandra.

However, this should be a win-win cooperation. In Steyr company, where is the North heavy truck company that can give full play to her talents.

Through this processing center, the domestic high-precision processing capacity will be greatly improved, which is of great help to the development of the country.

For example, for the Spey engine, in the production process of the engine, some precision parts can actually be processed by our own party to improve the process and efficiency.

For another example, the heavy truck of our side should be slightly improved now. One of the most important aspects is the use of supercharger.

"After your wedding, our factory will have a new project." Qin Guan continued: "the engine of the North Heavy Truck we use now is still a naturally aspirated engine. We need to further improve it, tap its potential and turn it into a supercharged engine."

In later generations, when it comes to turbocharged engines, a group of old drivers are disgusted, saying that the power is not linear, that the service life is low, etc. they feel how knowledgeable they are. They don't know that in the field of trucks, turbochargers have long begun to enter the scope of use.

At present, China's own heavy truck project is many years ahead of history. Therefore, only the imitation Steyr 991 series wd615.00 engine is equipped on the heavy truck. This engine is the basic model of WD615 Series and adopts natural suction design; The power is 200 HP and can output 623n. M torque at 1400 rpm.

At the same time, the power of the engine can also be changed by changing the firing system, but the change is limited. Even so, this engine is the most advanced engine in China.

When there was no five axis CNC machine tool, it was impossible to process suitable turbocharged blades, so the supercharger was not considered at that time.

The principle of the so-called supercharger is actually very simple, that is, two linked fans. One fan is driven by the exhaust gas. Anyway, the exhaust gas is useless. It is used to blow the turbine blade. That's great. At the same time, when this blade is blown, it will drive another coaxial rotating blade, which is used to blow air to the engine. In this way, With the same displacement, more air can be sucked into the cylinder of the engine, more fuel can be injected, and greater power can be obtained. That's it.

As for its service life, in later generations, it is almost the same as that of the engine, so there is no need to worry at all. The use of new technologies will always be resisted by some conservative people and talk with their own experience. However, the promotion of new technologies will not be affected by these people. Look at later generations, although they are resisted, turbocharged engines have increasingly become the mainstream. As for heavy trucks, they are all turbocharged.

On Steyr's engine, this improvement also continues. Wd615.61 is modified by adding a waste turbocharger to wd615.00 and increasing its fuel injection.

After simple transformation, the power of this engine is increased from 200 HP to 260 HP, and can output 829n. M torque at 1600 rpm. It can be seen from the above characteristic curve that with only minor changes, all parameters of wd615.61 are better than wd615.00, which shows the improvement prospect of WD615 Series engine.

Therefore, it is a trend to install a supercharger on the engine. Of course, even Steyr company has tried in this regard and has not completed the model development. Now, if it is reformed in China, it has been standing on the same starting line.

However, this turbocharger cannot be produced domestically.

There are many manufacturers of superchargers, such as KKK K28 of Hans, Holset H2C of NiuGuo and Garrett ta45 of Yingguo. At that time, they were also imitated in China, such as Dongning gj80, Hongyuan K28 of KKK and Wuxi Power J90.

However, the performance of these superchargers is not good. Finally, the flow range, maximum speed and compression ratio of Holset superchargers are better than those of other manufacturers and are widely used.

In later generations, some manufacturers made their own engines and hyped that we used the world famous supercharger. In fact, there were almost no domestic products, all of which were imported.

Advanced turbochargers cannot be produced. On the one hand, the shape of internal turbine blades is very special and cannot be processed in China. On the other hand, turbochargers are prone to tens of thousands of revolutions. Without high-performance bearings, they simply can't bear it. All these need advanced processing equipment.

Now, we already have turbochargers. It's a piece of cake to produce turbochargers. Now we start research and development. Maybe in the future, our turbochargers can be sold all over the world!

Only by relying on the strength of industry can a country be truly strong. It is an act of fishing with all its strength to produce advanced products that sell well all over the world. It is only relying on real estate to improve the so-called chicken fart.

Qin Guan inexplicably thought of later generations.

Now, hearing Qin Guan's suggestion that it should be transformed into turbocharging, Sandra immediately agreed: "yes, this is the trend of heavy truck industry in Europe. If we have five axis CNC machine tools, we can certainly produce them!"
