Brothers, if you don't subscribe, please don't subscribe for the time being, don't be depressed if you've already decided, go to sleep now for a thousand years, and then write a new chapter on the basis of this chapter when you get up,

――――――――――――――――

As an engine and automotive expert, Mr. Song Jingying knows the XJ750 engine very well, and it is precisely because he knows this engine very well that he understands the significance of increasing the maximum power of the XJ750 to 32 horsepower under the premise of improving reliability and stability: this is not a simple performance upgrade, but gives the XJ750 a chance to transform!

"Yes," Chen Geng nodded, "Our set goal is to have 10,000 kilometers of engine failure and 50,000 kilometers without major repair under normal use and maintenance." ”

A low-revving engine with 10,000 kilometers without failure and 50,000 kilometers without major repairs sounds like a joke: are you joking, or are you joking, or are you joking?

However, this is the case with the current engine technology in China, whether it is the 2.5L displacement gasoline engine that the Capital Internal Combustion Engine Plant supports for the 212 Jeep, or the SAIC Group for the sample; amp; The 2.2L inline six-cylinder gasoline engine equipped with the Hai brand car needs to be overhauled for up to 40,000 kilometers, including the boring cylinder!

The engine on the car is still like this, and the motorcycle engine is even more unbearable, whether it is the happiness 250 or the Yangtze River 750. The overhaul cycle recommended by the manufacturer is 20,000 kilometers. But in practice, it is very rare to reach this number. In order to ensure the performance of the vehicle, the fleet of each unit basically has to overhaul the engine at 15,000 kilometers, but considering the traffic conditions of this era, it is basically overhauled once a year, and this frequency cannot be regarded as "high".

Mr. Song Jingyingao is very aware of the "strength" of the domestic engine industry, and it is precisely because of this that he is so surprised by the two figures that Chen Geng said.

But what surprised him was still to come.

"This is our goal for the first phase," Chen said, "and our goal for the second phase is to increase the interval without major repairs to 100,000 kilometers......

Chen Geng's words were ambitious. But listening to Mr. Song Jingying's ears, he sighed instead and said: "Xiao Chen, it's good to have ideas, but you can't be ambitious in doing things, you still have to be down-to-earth, do you know what the concept of 100,000 kilometers without major repairs is?" With the level of our country in terms of materials and processing technology, I am already very satisfied that you can do 50,000 kilometers without major repairs......"

Now he couldn't help but start pondering Zhuang Qun's words: Could it be that what Xiao Zhuang said was true? Chen Geng, this kid, was really carried away by the little achievements he had already made, and began to flutter?

Chen Geng was stunned, and then smiled bitterly in his heart: "Teacher." Do you really think it's so difficult to increase the engine overhaul-free interval to 100,000 km? ”

Although the old gentleman didn't say it, he had already guessed what the old gentleman was thinking.

"Of course it's hard." Mr. Song Jingying nodded very seriously and said: "You are learning cars and power, you should know that compared with the improvement of power, the improvement of reliability is actually the most difficult, and it is actually very simple to improve the power, heap speed, heap displacement, heap compression ratio, heap turbine...... These methods can easily increase the power of the engine.

But reliability requires real effort, you need to endure loneliness, step by step, which involves not only technology, but also corporate management and cultural ......"

When it comes to reliability, there is probably no one who can beat the Japanese, but in this era, how far can the Japanese engine, which is known for its reliability, go?

First-line brands such as Toyota and Honda can achieve an average of 500,000 kilometers without major repairs under normal maintenance!

Second-tier brands such as Daihatsu and Suzuki can also do 300,000 kilometers without major repairs!

As for motorcycles...... The famous Honda Cub, which is known as a "motorcycle that cannot be destroyed", is still running without oil for three or five years after buying it.

Chen Geng has no good impression of the Japanese, and the Japanese have never been willing to invest in the most advanced technology in the engine, but it must be said that the Japanese have achieved the ultimate in reliability, whether it is a European car brand or an American car brand can not be comparable to the Japanese in terms of reliability, why can Japanese cars quickly become a pole in the world automobile industry in the world in just two or three decades after the war by European and American companies are extremely feared?

It's all about unmatched reliability.

"I know what you said, but if we can do 50,000 kilometers without major repairs, why can't we do 100,000 kilometers without major repairs?" Chen Geng asked rhetorically: "I know it's difficult, but you can't stop doing it because it's difficult, right?" ”

“……”

Mr. Song Jingying was stunned for a while, for a long time, he smiled bitterly in his heart: yes, he is not as good as a child, Chen Geng is right, it is indeed difficult to improve the reliability of the engine, but we can't stop doing it because it is difficult, on the contrary, it is precisely because reliability is so important for a car that we should have a ruthless and stunned spirit of "knowing that there are tigers in the mountains, and biasing towards the tigers", otherwise why make cars? Why do you want the people to recognize you?

"I'm almost 70 years old, and I can't even see it as well as your little guy." Looking at Chen Geng, Mr. Song Jingying was emotional, relieved, and a little annoyed: such a good seedling, why didn't he notice it at the beginning, and he missed it?

The more he looked at Chen Geng, the more pleasing Mr. Song Jingying became, and suddenly asked Chen Geng: "Xiao Chen, do you have a partner?" ”

"Object?" Chen Geng was stunned for a moment, and felt awkward in his heart: "No." ”

"If I'm not mistaken, you're 23, right?" Mr. Song Jingying said: "This is about to celebrate the New Year, and the New Year is about to be 24, starting a family is a lifelong event, and it's time to think about it." ”

"Yes...... What are you talking about......" Chen Geng said embarrassedly, his life's major events, he still haven't figured it out.

Before Chen Geng could remove the figures of Ding Ruoyan and Qianmo from his head, he heard Mr. Song Jingying say, "In that case, let me introduce you to one." ”

“……”

Chen Geng's eyes were about to pop out: Teacher, aren't you? Anyway, you're also a member of the quasi-school department, how can you still do this kind of media pulling line?

Facts have proved that the matter of pulling the line of the media really has little to do with whether it is a member of the school department or a quasi-school member, "I have a colleague, his granddaughter is a sophomore this year, her personality is quiet and quiet, she cooks a good meal, and she looks very beautiful, and she is quite a good match with you. ”

――――――――――――――――

Chen Geng didn't know how he fled back to the East China Hotel in embarrassment...... That's right, it's not running, it's running away...... Chen Geng always thought that middle-aged aunts were a group of terrifying creatures, but now he knew that the old man was not much better than the middle-aged aunt when he was terrifying.

Chen Geng, who was frightened, solemnly told Cui Hongjun that in the past few days, he would make every effort to prepare for the speech of the outstanding young pacesetters of the whole army, and no matter who came, he would not see him.

Cui Hongjun greatly agrees with this, the selection of outstanding young pacesetters in the whole army is very harsh, Chen Geng can be shortlisted as an outstanding young pacesetter in the whole army is not only his personal pride and honor, but also the pride of the entire East China Military Region, Chen Geng's performance on the podium directly represents the image of the East China Military Region, and it should and must be well prepared.

Although he is a man of two lifetimes, he has also participated in a lot of large and small commendation meetings, but Chen Geng has never participated in this level of commendation activities, what to do in this report, what to pay attention to, Chen Geng's heart is really a little empty, but soon, Chen Geng knew that he was thinking too much: the military region not only helped him draw up a speech, but also sent special personnel to train himself on what to pay attention to, how to speak, and how to walk in such an activity......

During this time, Chen Geng was in agony, and after he was finally done, Chen Geng got into the car as if he was running away.

There were also Huo Dongfang, Wang Damin and Feng Hua of Xiangjiang Machinery Factory in the car, Feng Hua sat on the bed with a butt and said with a satisfied face: "Your Runhua Industry is really comfortable, it is too luxurious to buy a sleeper ticket after spending one night on the train." ”

Chen Geng looked at him with a frightened expression: "Didn't you come from the sleeper?" ”

From the strain amp; amp; Zhou to the capital, this distance is not close, with the slow speed of the train in this era, conservatively estimated to sit for 5 days, Chen Geng can not imagine what the concept of sitting for 5 days is a hard seat, anyway, Chen Geng himself is resolutely not to do it, even if he drives all the way, he is also resolutely not to sit on the hard seat.

"I bought a sleeper ticket halfway through," talking about the experience of coming to the capital this time, Feng Hua's face palpitated: "In the past, I could get a part of the reserved sleeper tickets through the railway, but before I came this time, it was really evil, strain; amp; There was not a single sleeper ticket in the continental section, and we sat in a hard seat for two days before the conductor helped exchange three sleeper tickets. ”

“……”

Chen Geng looked at these three people with a sympathetic face, he really couldn't imagine how they survived by doing hard seats for 2 days in a row, could it be that in response to that sentence, people are cheap, there is no hardship that cannot be endured, and there is no happiness that cannot be enjoyed?

However, Huo Dongfang, Wang Damin and Feng Hua are obviously much more interested in Haizhou than in sleepers, and the four of them are talking more about how to build this Chinese version of the Fiat 126P, but Chen Geng is moved in his heart and said: "Director Huo, Wang Ke, Chief Engineer Feng, I think our thinking can be a little more broad?" ”
