"Chen Dong, these are some of my thoughts on the future development of diesel engine technology in our company, you can take a look. Pen, fun, pavilion www. biquge。 info" Liu Changming politely handed Chen Geng the diesel engine development plan that he had definitely written with great effort during this time, and looked at Chen Geng's eyes with a trace of awe.

For Runhua Industry, the past half a month can be described as ups and downs, from the beginning of the surprise, wind and rain, to the subsequent Chen Dong shot, the first moment is still turbulent, the next moment is calm, Chen Dong's ability is undoubtedly displayed, everyone originally thought that after this turmoil, the company's sales data will have a landslide, but did not expect that the sales situation not only did not appear a landslide, but took advantage of this incident to promote the company. In particular, the practice of inviting reporters to visit the production process of automobiles and motorcycles is simply a stroke of genius, and those reporters who visited it instantly changed from "Runhua Black" to "Runhua Blowing", and tried their best to advocate for Runhua Industry in the newspaper: in the face of this kind of quality management, Runhua Industry will never let an unqualified screw enter the market - of course, let the reporters say such things, and the rich red envelopes they received are also indispensable.

"Okay, I'll take a look."

If gasoline engines and gasoline-based vehicles are more for enjoyment, then diesel engines and all kinds of diesel-based means of transportation -- including but not limited to land and sea and inland rivers -- are the backbone of a country's economy and defense industry, and their role is equivalent to red blood cells in the blood, transporting oxygen to all parts of the body.

Therefore, in terms of contribution to the country's economic development, the gasoline engine is far inferior to the diesel engine, and Chen Geng is more eager to hope that Runhua Industry can produce a world-class diesel engine - if there is no way to be world-class, the world's second-rate is also good.

"Cooperate with AVL, a world-renowned engine design company, to develop a series of advanced diesel engine products; Cooperate with the world's advanced vehicle enterprises to introduce advanced models and advanced engines; Try to ...... with ship power giant Wärtsilä"

Seeing the name "Wärtsilä", Chen Geng subconsciously swallowed his saliva, and he couldn't stand it anymore: he didn't expect Liu Changming's appetite to be so big!

For ordinary people, and even many car enthusiasts, Wärtsilä is a completely unfamiliar name, many people may not have heard of it in their lifetime, but in the field of shipping and shipbuilding, this name is not only a thunderous and famous problem, Wärtsilä is a well-deserved No.1 in the field of civil ship power!

How good Wärtsilä is, just give you an example:

In order to meet the economical power system requirements of large (3,000 to 10,000 standard sea containers) and high-speed (25 knots constant cruising, approx. 46.3 km/h) container carriers, Wärtsilä has developed the world's first 14-cylinder civilian marine low-speed engine, which has 14 cylinders and achieves a thermal efficiency of an astonishing 50% (25% to 30% for typical automotive engines).

Let's talk about the size of this big guy: the whole machine is 27.3 meters long, 13.5 meters high, the exhaust volume of each cylinder is 1820 liters, and the whole machine weighs 2300 tons!

To put it simply, this big guy is basically the size of a six-story residential building, and weighs as much as half a fully loaded train.

The numbers are staggering, right? But what is even more amazing is the performance of this engine: the maximum continuous output is 80,080kw (108,920 horsepower), and the speed is as low as 92 rpm~~102 rpm!

You read that right, it's not 920 rpm, it's not 1920 rpm, it's 92 rpm, and the engine speed is 92 to 102 rpm, which is almost the limit of the speed of a large low-speed diesel engine, but Wärtsilä has done it.

The secret to Wärtsilä's ability to do this lies in the extraordinarily long bore and stroke ratio: the cylinder bore is 960 mm, but the piston has a travel of an astonishing 2500 mm, or two and a half metres!

Well, this "most economical" means that this engine needs to consume 6,400 liters of fuel per hour at the best efficiency - basically, this engine burns enough fuel in an hour for the owner of a family car for seven or eight years.

It is precisely because he understands the position of Wärtsilä in the field of ship power that Chen Geng has never thought of the idea of fighting Wärtsilä, but Chen Geng has seen what it means to be a newborn calf who is not afraid of tigers, and he still does not dare to fight Wärtsilä's idea, but he did not expect Liu Changming to start thinking about Wärtsilä.

Pointing to this report, Chen Geng said depressedly: "Liu Gong, why do you think Wärtsilä will cooperate with us?" Let's not say whether Wärtsilä will cooperate with us, even if it is, they will give priority to Dalian Marine Diesel Engine Factory, Qindao Marine Diesel Engine Factory, these professional marine diesel engine manufacturers, right? No matter how bad it is, Shanchai, Weichai, Changchai, these diesel engine production units can also be considered, our Runhua Industry now only has one diesel engine product, Wärtsilä as long as it is not blind, they will not be able to choose our ......"

"Chen Dong, I don't agree with what you say," Liu Changming shook his head, looked at Chen Geng and said seriously: "I believe that there are no insurmountable difficulties in this world, as long as it is good enough to achieve the right way, it will always be successful...... Just like our Runhua Industry, before this, who would dare to think that it only took you three years to bring our Runhua Industry to this point? ”

Chen Geng hurriedly waved his hand: "This is different......

"I don't think it's any different," Liu Changming said stubbornly: "That's right, Wärtsilä is the world's No. 1 ship power manufacturer, and the selection conditions for partners can be called harsh, which is higher than Volvo, MTU, MAN, Pierstick, these ship power manufacturers, and Wärtsilä's partners, but this does not mean that we have no opportunities, I analyzed, we actually still have opportunities." ”

"Oh? How so? What are our advantages? Chen Geng's tone was a little perfunctory.

"Our biggest advantage is not that we have experience in the production of diesel engines and certain technology, but as long as we want to do something, we will work hard to do it, and we don't need to aim at Wärtsilä's highest-end products, we can introduce some entry-level products, such as 4L20, which is the height that we can reach as long as we step on our feet......"

Chen Geng had already pondered.

He found that as the scale of Runhua Industry became larger and larger, his thinking seemed to become more and more conservative, and Liu Changming was right, what about Wärtsilä being the world's largest and most technologically advanced ship power manufacturer? For example, the 4L20 engine, which is the entry-level model in the Wärtsilä product range, is not only used in inland and offshore vessels, fishing vessels, but also in the manufacture of diesel engine units.

Wärtsilä's high-end engines, of course, are not qualified to be touched by Runhua Industry now, but are those low-end entry-level products not good? Even if it doesn't work, then can you go to seek cooperation with other companies, by the way, Scania doesn't seem to have a good time, even if Wärtsilä can't, you can go to Germany to find a way.

After figuring it out, it was easy to do, Chen Geng immediately nodded: "It's me who thinks about things too seriously, that's right, no matter what, let's try to talk about it first, even if Wärtsilä can't do it, MTU, Volvo, Scania, MAN...... We can always find a partner, and I have your back. ”

"Then I'm going to prepare?" With Chen Geng's permission, Liu Changming asked excitedly.

"Go ahead, if there is anything that needs the company's cooperation, just say, the company will do its best to cooperate with your work."

"Then I'll go and prepare!" Liu Changming nodded heavily, his round face flushed with excitement.

Before this, he has been prepared to convince Chen Geng many times, after all, it costs money to introduce power systems from the world's first power company, Liu Changming, who has many years of experience working in large enterprises, knows very well how difficult it is to persuade leaders to spend money on technology, although Runhua Industry has never been stingy with investment in technology, but Runhua Industry seems to prefer to solve technical problems by itself, and seems to be indifferent to the introduction of technology.

Liu Changming, who was just about to lift his feet to leave, suddenly thought of something, hesitated for a while, and finally couldn't hold back, and asked: "By the way, Chen Dong, I heard that many enterprises in the Soviet Union are not very prosperous now, I don't know if I can find some technology in the Soviet Union?" ”

"Huh?" Chen Geng was stunned for a moment, and asked quietly, "Why do you say that?" ”

Liu Changming didn't know that Chen Geng had already made up his mind in his heart, and explained seriously: "The engine technology of the Soviet Union is still okay, although the fuel consumption is higher, but it is also the first-class level in the world, if the situation in the Soviet Union is not very good now, we may be able to obtain the corresponding technology at a relatively low price." ”

"There is also the corresponding material process." Chen Geng added.

"Yes, yes," Liu Changming nodded excitedly: "The Soviet Union is still very powerful in heavy industry, especially in material technology, doesn't our company have a trade department with the Soviet Union?" I thought I could give it a try. (To be continued.) )
