Depressed to depressed, sad to sad, but in the face of a 40% weight reduction, 30% increase in power output, and 40% fuel saving, the fool also knows how he should choose at this time, after scolding Lin Hongfei and sending the reporters, Comrade Guo clamored to see the engine that was blown into the sky by Lin Hongfei.

Before seeing the engine with his own eyes, Comrade Guo still had a half-believing attitude towards Lin Hongfei's words, but when he saw the engine, he didn't speak, and his face was sad: He knew the engine.

Pointing to the engine and said to Lin Hongfei, "Mr. Lin, isn't this the 5.7L V8 engine you equipped on that Humvee, if I'm not mistaken, the performance of this engine shouldn't be as good as you said," he pointed to a special device on the engine, "This should be a supercharger, right?" Where is the exhaust gas turbocharger? ”

Of course, he was not mistaken, the 5.7L V8 naturally aspirated engine developed by Lin Hongfei before only had a maximum power of 275 horsepower and a maximum torque of only 525 Nm, and the output increased by 30% after installing a supercharger and exhaust gas turbocharger? Doesn't that mean that the maximum output of this engine has increased to 358 horsepower? That's not a small number.

"This is actually just an engine equipped with a supercharger, what you really want to see is this one," Li Hongfei forcefully pulled away a red silk thing next to him, and a brand-new engine came into view, "This is the engine with a double-supercharged structure, and I readjusted the ratio of cylinder and stroke, and adjusted the engine from the previous long-stroke small bore that focused on large torque output to a short-stroke large bore that emphasizes power output." ”

Before engaging in administrative work, Lao Guo was also the deputy chief engineer of the company, and he knew much more about technical skills than ordinary officials. Wen Yan immediately compared it with the engine next to him, and sure enough, the cylinder part of this engine was obviously a lot shorter than the one next to him.

"With the introduction of double supercharging, the crankshaft, the piston and piston linkage, the cylinder block, the cooling system and the valve system have to be redesigned, right? Do other parts need to be strengthened as well? "Comrade Lao Guo is an expert in technology, although his specialty is not the engine, but the technology has really reached the level of Lao Guo, and how many people do not understand the engine? Hearing this, he immediately asked Lin Hongfei.

"Yes, the middle cylinder is made of forged steel, which is made by cutting a whole steel billet, and the manufacturing cost of a single medium cylinder is 5 times that of an ordinary cast iron middle cylinder. Crankshafts, pistons, connecting rods are all made of high-grade forging materials, especially pistons and connecting rods, in order to meet the performance requirements, some special steel and processing techniques are used to strengthen the cooling system. In the valve system, in addition to the use of six-valve technology. Variable valve timing is also used to further increase the efficiency of the engine. Lin Hongfei was very frank. These things were not hidden from Lao Guo.

If he was replaced by another person, he would probably be excited to death, but Comrade Lao Guo didn't, not only was he not excited to die, but his face was still a little pale, and he asked Lin Hongfei cautiously. "What about performance? What about the actual performance? ”

Although I don't understand what the variable valve timing technique is, the six-valve technique is still known, the strength of the forged cylinder block is clear, plus the dual supercharging system of supercharging and turbocharging, especially the setting that emphasizes power output is deliberately adopted with a large bore of short stroke. Comrade Guo thinks that the maximum output of Lin Hongfei's engine should exceed 500 horsepower, right?

"Well, the maximum output is 625 hp and the maximum torque is 720 Nm. meters," Lin Hongfei smacked his lips, although he was very satisfied with this number, but there was one thing that made Lin Hongfei not very happy, "The only problem is that the material is still not good, according to the use conditions of the aircraft, every 200 flight hours must be used to do a comprehensive maintenance, 500 flight hours must be overhauled." ”

200 flight hours for full maintenance and 500 flight hours for overhaul? If this data is put on a jet fighter, it can make the ground crew smile from ear to ear, but on the piston engine, this is really a fatal number, but carefully calculated, even if the border guards use it every day, the use time will not be better than 6 hours, so it is actually only a month of major maintenance, two and a half months of overhaul, it is not bad, although his face is a little pale, Comrade Guo still pretended to be bold to ask what he is most concerned about, At the same time, the last question is also the most reluctant, "What about the cost?" How much does it cost to produce such an engine? What is the monthly production capacity? ”

"The cost of a single engine is 7 times that of an ordinary model," Lin Hongfei smiled bitterly, "As for the production capacity...... This depends on demand and the availability of certain specialty steels. ”

Understood, Comrade Guo nodded, there is no doubt that the previous star-shaped nine-cylinder engine can meet the requirements of use, but it is not excluded that some departments will require higher performance, at that time this more powerful engine can come in handy, but the demand for this engine is too little, although the performance is excellent, and it is much cheaper than the turboprop engine, but it still seems that the price is obviously not something that the army can afford to use now. At least not what they can afford to use in large quantities.

"So what?" Comrade Lao Guo asked Lin Hongfei, he absolutely didn't believe that Lin Hongfei had put so much effort into making such a thing, just to put it here to look good, with his understanding of Lin Hongfei, this is definitely not this guy's style of doing things.

"So I hope Mr. Guo can go to the major military regions to take a look, as far as I know, all major military regions have the idea of setting up special forces, this thing can not only become a sharp weapon for special operations, but also can be used as training equipment on weekdays, even if it is training parachuting, it is much lower than the cost of using military aircraft, right?" Lin Hongfei said, this guy finally revealed the true thoughts in his heart.

Let me lobby the major military districts? Comrade Guo's mouth opened unconsciously, and he couldn't close it for a long time.

"What? Are you scared? Lin Hongfei smiled, "You Bingfei worked so hard to develop helicopters, didn't you just look at other flying machines, you Bingfei has no chance to get in, I heard that at the end of last year, you visited a lot of bigwigs from major military regions in Beijing and sold your Bingfei helicopters to them?" Since you even sell helicopters, it's not too much to sell a few power delta wings, right? ”

"Do you know this?" Comrade Guo's mouth was open, but after taking a look at the engine in front of him, he swallowed: This is a good thing......

————————————————————————

After three months of construction, the supermarket that was rectified on the basis of the war-ready warehouse of the former Beijun City Military Division was finally nearly completed, according to the fat man, that is, as long as he chose an auspicious day of the zodiac, he could open, and it was not until this time that the fat man realized a very important problem: he was busy with his heel on the back of the head a few days ago, and he forgot to give his supermarket a good name!

Is this worth it? For a business, the importance of a good name is about the same as the importance of a person's name, where can this kind of thing be sloppy? When Lin Hongfei's face was here, the fat man was anxious, and his mouth kept muttering, "How can this be good?" How is this good? ”

"Why don't I help you get one?" Lin Hongfei couldn't help but laugh and said to the fat man.

The fat man is extremely skeptical of Lin Hongfei's ability to name the company, he does not doubt Lin Hongfei's ability to make money in business, but he has always been grateful for Lin Hongfei's name for people, if it weren't for the time being too tight, he would definitely not give Lin Hongfei such a chance, but since the matter has come to this point, there is no way, so he has to try the dead horse as a live horse doctor, despite this, he still carefully told Lin Hongfei again and again, "Hongfei, you must choose a nice name, Don't have a name like a flower, a root or something like that. ”

"Fatty, you don't scold people like that, right?" Lin Hongfei was furious, "This name is something I finally came up with, believe it or not, if you dare to say a crooked word, I will sell this name to others." ”

"You've got it all figured out?" Hearing Lin Hongfei's words, the fat man was immediately overjoyed, and rubbed his hands excitedly, "Then hurry up and say it and let me give you a detailed reference, buddy." ”

Seeing that this guy was already in a hurry like an old donkey, Lin Hongfei extinguished his thoughts about cleaning up this guy and said, "Two names, one is called Wal-Mart and the other is called Carrefour." ”

After talking about the famous names in the land of the Republic in the past two decades, Lin Hongfei suddenly had the urge to laugh: Carrefour, Wal-Mart Stores, Inc., when your two companies enter the Chinese market, think of a catchy name.

"Walmart? Carrefour? Hearing these two names, the name Wal-Mart didn't make the fat man do anything, but after chewing the three words Carrefour in his mouth, the fat man's eyes suddenly lit up, "Wal-Mart?" What a messy name, it's too ugly, it's better to compare it to Carrefour, and it's more in line with the aesthetic point of view of our people: Carrefour, every family is happy and blessed, good! That's it! ”

"Chosen Carrefour?" Lin Hongfei had expected this result and asked calmly.

"That's it," the fat man nodded solemnly, "I also plan to use the phrase 'happy and blessed families' as a promotional slogan, what do you think?" ”

"Great!" (To be continued.) )
