Chapter 222: Technical Roadmap

Rectifying the order of the factory, that is Zhao Guodong's business, Qin Zhenhua only has to make suggestions, anyway, Zhao Guodong is not afraid of offending people, and the development of new diesel engines requires the construction of a research and development team, determine the technical route, from now on, it can be regarded as on the right track.

Everyone's emotions have been stirred up.

"Hmph, every time I see Lao Zhang, it's like that, high up, they don't look down on us at all."

"When it comes to technology, they're like experts, and we're like idiots, because they've always despised us."

"That's it, we can't afford to lose to them!"

Everyone began to talk about it, at this time, because everyone was sitting, they could only hear the voice, and they couldn't see the figure of others through a few tables, in fact, the first to speak were the masters of the maintenance workshop that Qin Zhenhua had arranged a long time ago, and they were responsible for picking the lead, so if they complained, naturally someone would follow suit, and then, public opinion was formed.

They are a diesel engine factory in the coal province, relying on the unique advantages of diesel engine technology, they can't look down on us!

"If we don't fight for steamed buns, we must not lose to them."

"That's right, that is, their engine has 700 horsepower, we can get 1,000 horsepower, as long as we brainstorm, we will definitely be able to do it!"

Speaking of which, that's almost it, Qin Zhenhua looked at everyone and couldn't stop nodding: "That's right, that is, as long as we make up our minds, we will definitely succeed, didn't they also produce diesel engines at the beginning?" Now, let's just not accept this tone, we must complete this battle, now, let's discuss in detail, if we want to achieve this performance index, what technical route should we take. ”

Now that we have a common goal, the next step is to strive for this common goal, and it is definitely not easy to achieve a thousand horsepower output.

Seeing that everyone calmed down and fell into thinking, Qin Zhenhua was the first to speak: "Our previous engines were all supercharged, and this is power-consuming, and now, the mainstream of the world is turbocharging, and the technical content of this turbocharger is quite high. ”

Mechanical supercharging, is to drive a supercharger on the engine, the faster the engine speed, the more air is blown in, so the most direct, there is no delay, however, to waste a certain amount of power, so, the new diesel engine, have begun to use exhaust gas turbocharging, anyway, the exhaust gas discharged by the engine is useless, let it push the turbine blades to rotate, drum in more air, can also increase the power output, so that although there will be hysteresis, but, do not waste mechanical power, is a trend.

"Can you make a turbocharger?" Wu Ruihua spoke for the first time, just now, he had been listening to everyone say that he was a bystander, keeping a clear head, and now, this young man said that he could make this highest-tech component, and he couldn't help but raise questions.

This is a complex part, the processing of the blades, the need for high precision, the material also has requirements, when the full power is working, the entire supercharger will be baked red by the exhaust gas discharged by the engine, at the same time, the turbine blades inside, full tens of thousands of revolutions, there ball bearings, is not so easy to make.

Qin Zhenhua nodded: "We have introduced CNC machine tools from abroad, and when foreign advanced processing machine tools are in place, we will be more sure." ”

"However, CNC machine tools are not something that ordinary people can operate." Of course, Wu Ruihua knew how difficult it was, and when a machine factory developed the CNC machine tool for its own use, Wu Ruihua also followed the past to help.

"I'm a two-dimensional person." Qin Zhenhua said with a smile: "This bag is on me." ”

Wu Ruihua nodded: "If turbocharging can be made, then hang on our existing engine, strengthen the piston connecting rod, and it will definitely increase the power." ”

This is also the first technical route that everyone can think of, after all, everyone's foundation is weak, and the use of the existing 150 series diesel engine to improve is the most secure plan.

China has never been engaged in research and development, are surveying and mapping imitation, according to the scoop painting gourd, so fastest, but the defect is that the technology can not be thoroughly understood, it is not clear why it is so designed, it can not be improved.

Just one improvement will take a lot of detours, and as for positive research and development, don't even think about it.

"That's right, let's get a turbocharged 150 engine!" Yang Zicheng quite agreed with Wu Ruihua's plan.

Turbocharging, more air is pressed, more fuel is injected, and in this way, the power can be increased with the same displacement.

"Guys, everyone is a technical talent in the engine, think about it, if we only rely on external turbos, can we achieve the target of 1,000 horsepower?" Qin Zhenhua asked everyone: "Compared with the current products, how much can we improve?" ”

These people are carefully selected, although they are only workshop workers who produce diesel engines, but they all have enough theoretical skills, and soon, Wu Ruihua gave the answer: "If you can increase it by 50 percent, you can increase it by 500 horsepower to 750 horsepower, and then it will be the end." ”

This master, Qin Zhenhua is admired, the first time he went to the foundry workshop that day to find out, this master invented and created a new coal furnace, indicating that he usually likes to ponder.

The answer he gave is very reliable, in fact, the 730-horsepower diesel engine developed by the current Coal Province Diesel Engine Factory is taking this technical route.

The original foundation limits the performance improvement of this engine, which is the conclusion that Qin Zhenhua has given.

"yes." "It's not easy to keep boosting your motivation unless..."

"Unless the speed is increased." Yang Zicheng took over his words, and now, in the cafeteria, the atmosphere of discussion has become warm.

On the one hand, the gas thrust of each push piston can be increased, and on the other hand, the diesel can be burned more times in the same time, which is to increase the speed.

"No, if you want to increase the speed, then our engine, the connecting rod is too long, it is inconvenient to move back and forth, unless you use a short connecting rod. In this way, the structure of the entire engine is changed. ”

Finally to the point, if you want to increase the speed, you have to make the distance back and forth shorter, that is, the piston, connecting rod, you have to use a short one, in fact, the engine of the Leopard-2 tank, take such a technical route, its own engine, only 2,000 revolutions per minute, and the Leopard-2 engine, 2,600 revolutions per minute, the power reached 1500 horsepower.

You don't have to be so against the sky, it is enough to achieve 2,400 rpm, otherwise, you have to be like the Leopard-2, with a big butt on your back, the speed is so high, the heat is too big, and the result outweighs the loss.

"The truth is all refuted, and our technical route is about to come out." Qin Zhenhua said: "Turbocharging, reducing the length of the piston connecting rod, increasing the speed, under the premise of this big goal, we improve the existing engine..."

When he said this, Qin Zhenhua stopped, because Wang Erzhu hurriedly walked in from outside.

"What? Jump? Is it an old man? How to be the same as a! Hearing Wang Erzhu's words, Qin Zhenhua couldn't help but curse in disdain.
