"Yes, because of the failure of the imitation of 8V331TC41, the senior management finally realized that it is not possible to rely on imitation mapping alone, we can imitate the shape of the engine and parts to map out, but the Germans will not provide us with any information about materials and processing technology, but the modernization of the army is imperative, so after the failure of the imitation of 8V331TC41, combined with the current situation of China's domestic gas turbine industry, it is determined that it is simply unrealistic for China to independently develop a new high-power military diesel engine in a short period of timeAfter many discussions, the Ministry of Ordnance Industry and relevant factories and research institutes decided to introduce high-performance diesel engines for military and civilian use from abroad.

When we were in class, our teacher once told us that it was probably from the end of 80 and the beginning of 81 that the country organized a number of delegations to go abroad, and successively inspected the ANDS-790 tank diesel engine of the British Telleda company, the CVl2TCA tank diesel engine of the British Rolls-Royce engine company and the related diesel power enterprises in France and Germany.

The reason is because the military and civilian diesel engines of MTU company are produced and assembled on the same production and assembly line, that is to say, the main technology of MTU diesel engine is universal, and finally our country decided to introduce MTU company's 396-03 series diesel engine, this 396 series diesel engine is developed on the basis of 331 series diesel engine to increase the stroke, and it is also one of the most advanced military and civilian general diesel engines of MTU company at that time, which can be widely used in various ships, Large-tonnage mining dump trucks, oilfield machinery power, railway locomotives, construction machinery, power generation equipment and even power sources for special vehicles, and their technical level and overall performance are also at the advanced level in the world. After investigation, we are basically satisfied with the table of MTU's 396 series engines......"

"Then he said, then said...... "Li Jianguo listened a little intrigued, of course what Chen Geng said was not a secret, but he listened to it very much, if these things were not told to others, others would never want to know, Li Jianguo's interest was all aroused by Chen Geng, where would Chen Geng stop?"

"Okay," Chen Geng once again confirmed that what he said was not secret, and then said: "396-03 series diesel engines adopted a modular design concept at the beginning of the design, the basic form and layout remain unchanged, all are water-cooled four-stroke supercharged intercooled direct injection diesel engines, all cylinders are V-shaped, and the angle between the cylinders is 90 degrees, but according to different positioning and needs, the number of cylinders can be flexibly arranged, respectively, there are 6, 8, 12, 16 such cylinder layout schemes.

Depending on the cylinder options, the power ranges from 345 kW to 1920 kW, but in either case, the diameter of the cylinder is 165 mm, and the stroke of the piston remains unchanged at 185 mm. But in the end, which one or which options our country chose, the teacher didn't tell us......"

Li Jianguo nodded, not only did he not get angry, but he felt that Chen Geng's teacher was still very political, very careful about secrecy, and told his students about the German engines, and the anecdotes in the process of introducing engines, so that his students knew how big the gap between our country and the world's advanced level is, of course this is no problem, but which engine or engines our country has chosen, which is related to the country's national defense, it is indeed impossible to say.

Nodding, Li Jianguo motioned for Chen Geng to continue: "Didn't you say that you also helped translate some of the materials?" Let's talk about this part, well, pick up what you can say. ”

"That's after returning to China to demonstrate." Chen Gengdao, after thinking for a while, he said: "After returning from the German inspection, that is, last year, under the leadership of the Ministry of Ordnance Industry, the 396 engine team was established to conduct a comprehensive investigation and analysis of the domestic market.

After the investigation came back, the Ministry of Ordnance Industry organized experts to conduct comparative demonstrations, believing that the introduction of the German MTU company's 396 series diesel engine as a military and civilian general diesel engine is relatively the most suitable for China's current situation, and then in March last year, the Ministry of Ordnance Industry submitted to the central government the introduction of the German MTU396 series diesel engine project proposal.

During the period when the 396 engine team went down to understand the situation and waited for the approval of the central government, the Ministry of Ordnance Industry also organized a group of people who knew German and understood engine and vehicle-related technology to translate some materials brought back from the German MTU company...... Well, I've been there for more than three months. ”

Although Li Jianguo did not bribe Mu Rui Palace, he had to explain in such detail why he knew about this matter and why he knew it, which was a very strict matter.

For example, it was not until December last year that the State Planning Commission and the State Commission of Science and Technology officially approved the 396 engine team, agreeing that the 396 engine team would organize negotiations and contracts with the German MTU company to introduce the 396 series engine.

After the approval of the State Planning Commission and the State Commission of Science and Technology, I don't know why, it was not until July this year, that is, on the eve of Chen Geng's graduation, that the 396 engine team organized the final production place of this engine: the relevant leaders and technical leaders of Shanchai and the relevant units formed a group to go to Germany to conduct formal inspection and negotiation with the MTU company.

On the eve of going to Germany, because Chen Geng was excellent in translating materials last year, Chen Geng's teacher recommended Chen Geng to follow the inspection community to Germany as a professional translator, but at that time, Chen Geng was having an awkward relationship with his father, and he was angry with Chen Hongjun when he returned to the Third Ordnance Maintenance Factory of the East China Military Region ******** refused to listen to Chen Hongjun's words, and he was angry with Chen Hongjun, so he refused the teacher's kindness.

Listening to Chen Geng's explanation of the causes and consequences, Li Jianguo was indeed relieved: because he had previously participated in the translation of relevant materials of MTU company's 396 series engines, Chen Geng knew that the country had introduced 396 series engines, and Bin knew that some of the things were completely understandable: "Since you know all this, and it is not the first time to participate in such a confidential activity, then I won't tell you anything, remember one thing: confidentiality!" This time, you are going to translate German and professional vocabulary, and you can say what you should say, and you must not say what you should not say. ”

"Yes!" Chen Geng put his feet together and said loudly: "Please rest assured, I will keep in mind the discipline of confidentiality, say what should be said, and resolutely do not say what should not be said!" ”

"Very good," Li Jianguo nodded with satisfaction, thought for a while, and then advised: "Remember to tell your family, don't let them worry." ”

"Yes!" After saluting, he suddenly remembered Jindler's matter, Chen Geng hurriedly said: "By the way, chief, there is something I want to ask you for a favor......

"Hmm...... You said. Li Jianguo nodded.

"That's the case...... Chen Geng told Li Jianguo about Jindler's father, a World War II veteran, who had always wanted to collect a World War II-era BMWR71.

In later generations, many military fans and motorcycle fans know that the Yangtze River 750 is a replica of the BMW 750, but in this era, there are really few people who know the relationship between the Yangtze River 750 and the BMW WWR71, and Li Jianguo is obviously not one of them, he asked strangely: "What does this BMW 71 have to do with our Yangtze River 750?" ”

"These two are really related, in World War II, but the Soviet Union got a batch of BMWR71 through special channels, Stalin thought that BMWR71 is a good battlefield mobile vehicle, so he ordered the military industry to carry out surveying and mapping imitation, that is, the Soviet Union's Ural M72, and later after our country established diplomatic relations with the Soviet Union, our country obtained a full set of production technology for this motorcycle from the Soviet Union, which was named Yangtze River 750 so in terms of appearance, overall structure and engine structure, There is basically no difference between the Yangtze River 750 and the BMW R71. Chen Geng explained to Li Jianguo.

That's right...... Li Jianguo was immediately relieved.

Chen Geng added in a timely manner: "Kindler said that he was willing to pay for the car, but I didn't know what our policy was, so I didn't dare to agree to him, but just helped him ask." ”

It's just a motorcycle, Li Jianguo really didn't look at it, he waved his hand happily: "What kind of money to talk about?" In this way, I wrote a note on the logistics, and the car was given to him. ”

"This ...... Is it appropriate? Chen Geng was a little embarrassed.

"What's inappropriate," Li Jianguo didn't think it was a big deal at all: "In order to thank our German friends for their help to us, we sent him a motorcycle as a witness to the friendship between the two sides, who can say anything?" Wait a minute, I'll write you a note. ”

Although Li Jianguo can't manage other people's logistics, but the size of a motorcycle is just a motorcycle, for the sake of Jindeler to provide such a large financial resource to the East China Military Region, what is a motorcycle? No one will be serious with Li Jianguo for this little thing.

"That'...... What if I need more cars in the future? Chen Geng asked cautiously.
