In this way, the meeting on foreign trade tanks ended. This meeting was just a meeting that Qin Zhenhua wanted to hold temporarily to discuss the issues of the next foreign trade projects. However, even Qin Zhenhua did not expect that this meeting was
It has a far-reaching influence. Since then, the VT tank has become famous and has become the pillar of the export of foreign trade tanks of the Eastern powers. Moreover, in the bidding for exports, it has repeatedly defeated the advanced Western tanks and finally reached the world's leading level.
At this time, the meeting was over, and it was already late at night. Qin Zhenhua looked at Nie Qianqian with praise, and was quite satisfied with Nie Qianqian's proposal. Finally, a problem was solved. If you want to talk about naming, you will still give it to these liberal arts subjects.
It's the best to have a child.
"Director Qin, I'm back, resting for a few days, and I'm on a business trip again." Nie Qianqian said.
"On a business trip? Where are you going?" Qin Zhenhua asked.
"During the day today, weren't there many representatives who expressed their desire to purchase our tanks?" Nie Qianqian said: "This is a big event in the export of our tanks. We want to do a special tracking report and give it to us.
The tank exports are strong and powerful."
Qin Zhenhua nodded. He understood what Nie Qianqian meant. With this shot, the tanks of the Eastern Power began to become famous, and the number of purchasing customers increased. Taking advantage of this opportunity, he had to make his own reputation. Nie Qianqian did it.
This is the most appropriate thing.
"Qianqian, you are really one of our tiger generals." Qin Zhenhua sighed.
"I am also very happy to see our tank career grow and grow little by little. Director Qin, you are the real tiger general. I am just a fox. The fox is fake. " Nie Qianqian smiled.
Qin Zhenhua also laughed.
The next day, the engine branch.
"This system was completely developed by us. During the research and development process, it was strongly supported by Wang Gong. Without their support, we would not have developed this system." After Qin Zhenhua came back, what he cared about most
Of course, it was the research and development of technology. When I came to the engine branch, I saw the engine on the test stand, and listened to Wu Ruihua's words beside me, and I felt moved.
This engine, a 12-cylinder engine, was improved based on the original hb150 diesel engine, and the goal of improvement is to achieve a powerful power of 1,500 horsepower!
After changing to a new cylinder structure and increasing the cylinder center distance, the heat dissipation ability has been solved. The most important thing now is how to increase the power. As before, use a powerful supercharger to bulge more
At the same time, use a higher pressure oil pump to increase the injected diesel oil, while making the combustion more fully.
To achieve this, they also began to use new structures.
In the past, diesel engines were split-type oil pumps. There was a cylinder, an oil pump, and oil pipes were connected to the fuel injectors of the cylinder and injected fuel in the order of mechanical operation.
But now, this diesel engine is different. It only has one oil pump, and the high-pressure fuel provided by it enters a pipe above. This pipe is divided into the injection pipe and enters the cylinder. Such a pipe is called a common rail pipe.
A system is called a high-voltage common rail system!
This is the most advanced method of diesel engines. In the 1990s, Bosch had successfully developed and used their own diesel engines. The first-machine factory has already started to do pre-research. Now, it has already been available.
The result was used on your own diesel engine.
Compared with the past, the diesel pressure inside the common rail pipe has remained unchanged, so that the injector can always inject fuel in the most appropriate way, which can effectively improve the combustion efficiency, but at the same time, this also means spraying.
The oiler needs to master the opportunity and open the fuel injection valve to inject fuel. This control requires electronic equipment.
Unlike the previous diesel engines, this diesel engine also had an additional electronic control system, which was concentrated in a box, and also had an English abbreviation called ecu.
Hearing Wu Ruihua's words, Wang Xiaoqiang pushed his glasses: "These are all we should do, and this market will be very large. Although it is only for military purposes, it will definitely transition to the civilian market in the future.
At that time, our technology is the most advanced and will definitely bring huge economic benefits.”
Wang Xiaoqiang's forehead has begun to appear with gray hair. He is still tall and thin, just like before, but his glasses are thicker. Over the years, he has led the advancement of electronic technology and has been working day and night.
Many military technologies will be transformed into civilians. For example, the turbocharger technology of the engine is gradually transforming into civilians, effectively improving the performance of the engine. Now, this high-pressure common rail technology will also be
For the transformation to civilian use, the commercial prospects will be very good at that time.
Qin Zhenhua nodded: "Brother Qiang, you have changed too. In the past, you didn't care about any economic interests at all. You only care about technology."
"Yes, that was the past. Now, if there is no sufficient economic benefit, there is no way to promote technological development." Wang Xiaoqiang said: "To build chips, it will cost money. Only input and no output. So what if you want to do it.
OK."
After saying that, he pushed his glasses again. Unconsciously, his glasses were getting heavier and heavier.
"Director Qin, our engine has used so many new technologies and electronic equipment, will it reduce reliability?" At this moment, someone said on the side.
Tanks have always been sturdy and durable. Now, with high-end electronic equipment, the reliability cannot be guaranteed.
"Yes, this high-pressure fuel injector is too expensive. If our oil is too impurities, it will easily block the nozzle. Under field conditions, if there is no qualified fuel, what should we do?" someone asked again.
road.
Qin Zhenhua nodded. Knowing that these problems have been bothering everyone for a long time. I have not had the chance to mention them to Qin Zhenhua. Now, I have finally raised them.
Tanks must ensure reliability. If there is no reliability and failure on the battlefield, it will be fatal. In many cases, reliability is related to backwardness. After all, only backwardness can be reliable, so
A question arises: Are high-tech equipment reliable? Are too pursuing high-tech equipment going astray?
