Qin Zhenhua nodded in praise: "Your thoughtfulness is very thoughtful."
"But, we have calculated that without a high-power engine, it is impossible to drive such a chassis." Fan Gui said: "We are the weakest in terms of engine technology, so we need your technical support
ah."
"What engine is used in Sanjiang Factory?" Qin Zhenhua asked.
Since Sanjiang Factory has started mass production, there must be a solution.
"In our country, there is no qualified engine at all. In order to pursue the life of the vehicle, it cannot be replaced by tank engines. Therefore, Sanjiang Factory currently uses an imported commercial Cummins KTTA19-C700 diesel engine with a maximum power of only 700 horsepower.
The same type of Russian missile launcher MZKT-79221 uses their YaMZ-847 diesel engine with a maximum power of 847 horsepower and a very large torque gap. Therefore, Cummins' engine has a serious lack of power, although Sanjiang Factory has made it
The seven-axis and eight-axis chassis can only use a six-axis power system. Therefore, the 7-axis WS21050 is designed as a 14X12 drive, and the 8-axis WS51200 is 16X12 drive. Although it can move, it has off-road capabilities.
It's a big drop, it's just a semi-finished product."
When Fan Gui spoke there, he was still a little contemptuous. Sanjiang Factory was building a multi-axis missile launcher. Moreover, with the help of Belarus, it was progressing rapidly. However, it was hard for a skillful woman to cook without rice. Their seven-axis and eight-axis
The chassis still does not have a qualified engine, so the number of drive shafts can only be reduced. Although the appearance looks multi-axle, some of the shafts have no power. If you encounter complex terrain in the wild, there is no power to drive shafts.
If you need to work hard, this kind of vehicle will be stuck.
For multi-axis off-road vehicles, all shafts must have power. Now Sanjiang Factory has only produced semi-finished products. As for why the engines of the Russians are not imported, the reason is also very simple. On the one hand, the engine life of the Russians is not good.
The cost of using the troops is too high. On the other hand, this engine is not from Belarus, but from Damao. Damao will not export this engine at all for some purposes. Therefore, even if Sanjiang Factory wants to purchase it,
It can't be purchased at all.
After hearing Fan Gui's introduction, Qin Zhenhua nodded. Now, Qin Zhenhua already knows their needs, but it is very difficult to let Qin Zhenhua solve the current problem.
"Our commercial engines don't have such a lot of power at all." Qin Zhenhua said: "If it is a tank engine, it's almost the same. If the engine is used in a vehicle, we will develop the existing planned engine, and the engine will be
The power can only reach about 400 horsepower, which is twice as different from your needs.”
The engine of heavy trucks requires strong power, but that is also limited. For example, Steyr heavy trucks have more than 200 horsepower, which is already good. Later, as domestic road conditions continue to improve, the engine of heavy trucks
The power of the new engine has ranged from more than 200 horsepower to more than 300 horsepower, and is now steadily advancing towards four hundred horsepower. Therefore, the automobile branch of the first machine factory sets the power of the new engine at about four hundred horsepower, through different
Calibration can be 420 horsepower or 450 horsepower. In short, this is already a very powerful driving force.
Let’s look at the international heavy trucks with high horsepower, even if they use V8 engines, the power is only more than 600 horsepower, but there is still a gap between the eight or nine hundred horsepower they need.
"More than 400 horsepower is enough." At this moment, Fan Gui said again: "If one engine can output more than 400 horsepower, those two can achieve an output of eight or nine hundred horsepower.
It can meet our needs.”
Hearing his words, Qin Zhenhua frowned: "Director Fan, please calm down. Truck engines must not be used in series. Although they can be used as a douche, many problems will arise.
I would like to use this way, and I can understand your mood."
What a joke, he would have to install two engines into one car, and there would be many problems. This kind of operation is not uncommon. For example, the Soviet wheeled infantry fighting vehicle used two engines.
Although it can be used, the two engines have brought a lot of reliability problems, which makes the users suffer. If he gets on two engines, it would be better to use the Cummins engine with insufficient power.
It's not suitable at all.
"No, no." Fan Gui said: "Director Qin, if you have the technical reserves of more than 400 horsepower engines, then just double the number of cylinders of your engine, that's fine.
It is said that what you are now manufacturing is an inline six-cylinder engine. As long as it is changed to a V-shaped twelve-cylinder structure, that's fine."
"V12?" Qin Zhenhua quickly shook his head: "No, no, this is not possible. We do not have such technical reserves. If we do this kind of work rashly, there will be many technical problems. Don't force others to make trouble. This thing is made
Easy, but reliability is not guaranteed.”
"Why are there no technical reserves? The tank engines you made are also V12 structures?" Fan Gui said: "You can all improve the tank engines. Can't you still improve a car engine? Follow the tank engines.
The cylinder design of the V12 is then added to the various components of the current automotive engine. As long as the cylinder structure is changed, the rest are all made of the automotive engine parts. I believe it will be possible.”
Tank engines can be built, not to mention car engines!
"But, this requires investment." Qin Zhenhua continued to be embarrassed. Even if this kind of engine can be manufactured, the usage surface is too narrow. So how much can it be matched with their missile launch vehicles? It has been studied with funds
The engine has a small output in the end, which is not cost-effective at all.
"We invest the funds needed. After the engine is produced, we only have the right to use them. If other factories want to use them, we have to go through our consent." Fan Gui said: "Our factory has made up our minds, just
Just like the original surveying and mapping of the Scud missile launcher, we have to get this project even if we sell it."
