"OK, then use this engine," Lin Hongfei said, but his hand didn't stop, "What do you think of the five-speed manual transmission used in the Humvee?" ”

The gearbox of the Hummer can be called the most powerful gearbox among the domestic passenger cars, with a maximum torque capacity of 3000 Nm. m, more than the transmission capacity of many semi-trucks, even with this air-cooled V-six-cylinder diesel engine, with the transfer case's amplification efficiency of 4.11:1, this transmission is enough to withstand that huge torque.

Of course, in order to be able to withstand the impact of such a large torque, this gearbox has made a lot of sacrifices for this, in the case of material technology is not up to par, many parts that could have been made more fine and small have to be made "stupid big black coarse"; When the total weight and volume of the gearbox were strictly limited, a sacrifice had to be made: the original design of five forward gears was adjusted to four, for which a whole gear was sacrificed.

However, the sacrifice is worth it, although there are only four forward gears, the Hummer's off-road ability is outrageous, but in terms of off-road ability, it is not too much to say that the Hummer is the "king of off-road".

These Ding Science naturally knew it, and he nodded again and again, "Okay, the fighters have a very good response to that car, the performance is very stable, the car is also reliable and solid, even if the maintenance is not timely, it will not lose its temper, it is a good car." ”

"Then there is no problem, the front and rear axles of the car can be shortened on the basis of the front and rear axles of the Hummer DANA44, so that the car you want will come out......"

As soon as Lin Hongfei's voice fell, he put away the pen in his hand and handed the "result" of his hard work to Ding Science, "Minister, take a look." More guidance and more criticism. ”

"Then where do you dare to criticize, I'm a layman about cars," Ding Kexue said with a smile, but the movements in his hands were not slow at all, and he was also a little curious, what kind of thing did Lin Hongfei draw at this time? In the next second, Ding Science's eyes widened, his face was full of disbelief, and when he raised his head, Ding Science looked at Lin Hongfei with a shocked expression. "Won't it?"

The piece of paper in front of Ding Science is a sketch of the structure of a car, because of the hurry, many places have not been refined, but this is enough for Ding Science to see how the various subsystems of the car are installed. According to the data written by Lin Hongfei on it, it can be clearly seen that this is a light off-road vehicle that is basically the same size as the 212 Jeep. But it's different from 212. This light off-road vehicle is not light at all: it weighs 1.7 tons, which is more than 300 kilograms heavier than a 212 Jeep!

But it's all worth it, the 140 hp V-shaped air-cooled 6-cylinder diesel engine doesn't make this car run much faster, but 428 Nm. The maximum output torque of meters/2500 rpm is enough to put any off-road vehicle in the world out of reach;

The transfer case has an amplification capacity of 4.11:1 and a maximum of 1759 Nm after enlargement of the transfer case. meters of torque make this car completely fearless of any limitations;

The combination of a sturdy non-load-bearing body and heavy-duty axle structure, three front, middle and rear speed locks and low-speed four-wheel drive is enough to ensure that as long as the car has wheels on the ground, it can get out of danger;

The optional portal axle gives the car a ground clearance of up to 46 cm, and the fully enclosed engine and the intake and exhaust system are 20 cm higher than the body of the car, making it possible to dive without any preparation...... It's a pity that the body doesn't release water. So if you want to dive, it's best to have an oxygen cylinder ready;

As a high-performance military vehicle, the central inflation and deflation system of tires is naturally necessary, with the help of this charging and deflation system. The car is equipped with a set of airbags, and after the airbags are fixed and inflated through the anchors on the body, the goods can even make a temporary cameo appearance in the amphibious vehicle by paddling the tires or paddling with sapper shovels. There is no doubt that the car has a general-purpose machine gun, a 12.7mm heavy machine gun, and a 20mm cannon mount, which means that the vehicle can even carry out fire attacks and support operations while on the move;

In order to achieve multi-functionality and facilitate helicopter lifting, the car is designed with helicopter lifting anchor points, including the roof, doors and even the front windshield, many things can be removed, enough to meet the diverse needs of the mission;

And the iconic round headlights and hood fixing hooks look so familiar, just like the 212 Jeep, although the small window on the engine top cover is strange, but Ding Science has long been surprised, that is the heat vent, the OHV V-shaped six-cylinder diesel engine is equipped with a turbocharging system, how can it be done without giving a little more heat dissipation area?

The half-square-square, half-square-shaped air intake like a beast's bloody mouth, made Ding Science feel familiar: didn't this put up the big mouth of the 212 jeep horizontally? But even Ding Science has to admit that if the workmanship of this car can really reach the level on the picture, this car will look much more exquisite, and what is even more rare is ...... This cargo is independently suspended on four wheels!

That's right, this is the Wrangler, and it is the 2012 two-door version of the Wrangler Rubicon (Robinson) before Lin Hongfei came back, but unlike those Wranglers in later generations, the Wrangler sold in the United States now not only has iconic round lights or square lights, but the performance is much worse than the third-generation Wrangler Rubicon that began to be sold in 2007, but Lin Hongfei's difference, the overall performance is even stronger than the Rubicon...... The portal axle is a super bug!

Since the military has also put the Guqi Provincial Industrial Manufacturing Co., Ltd. into the civilian market after dismantling the military sensitive equipment on this car, Lin Hongfei has decided to use this car to impact the high-end off-road vehicle market in the world, and in order to make a hit, he has even decided to let this car go to the Dakar car rally...... No way, it's so cruel in the off-road world, no matter how awesome the paper data of your car is, until it is verified by the competition, everything is empty.

Dante Science can't think that far, the performance of this car is very advanced, too advanced, and the advanced is somewhat beyond Ding Science's imagination. For a while, he was a little incredulous, "Your company can really make such an advanced car?" ”

"It's not advanced, is it? A lot of things are ready-made, and you can just move them over and use them. Lin Hongfei said, he told the truth, in order to avoid the decline of his memory for a long time, one of Lin Hongfei's main jobs in the past two years is to record all the things that he has deeply understood in later generations, and the Wrangler, known as the king of off-road, will naturally not be missed.

Thinking about it carefully, Lin Hongfei also has to admit that compared with the Hummer like a tall horse, the compact and compact Wrangler is more suitable for our national conditions. Although the car is a little smaller, it seems that the aura is a little insufficient, but if it is a professional off-road vehicle, it is not much of a problem.

"Isn't that advanced?" Ding Science was speechless for a moment, but thought about it carefully. It seems that what Lin Hongfei said is not unreasonable, or in the eyes of Lin Hongfei, this kid can only be regarded as average? Well. Compared to the large aircraft of the North County 200 class. It's nothing.

Ding Science, who knew that he couldn't fight with Lin Hongfei on this kind of thing, immediately changed the topic, "The car looks good, but when will we be able to build a few prototype cars for Lu testing?" ”

"A week." Lin Hongfei roughly calculated in his heart, and then gave a time limit.

"A week? So fast? Ding Kexue was taken aback, almost biting his tongue, his eyes glaring like cow eggs: a week? You're exaggerating, aren't you? Why don't you say a day?

Lin Hongfei knew very well that Ding Science's expression was so resentful. It's as if he pointed to a lump of things and told him that it was cake, and this guy believed it, and took a hard bite only to realize that he had eaten the wrong expression, so he had to explain, "Oh." This is a new high-performance model that our company plans to launch next, ready to be used to participate in the Dakar Rally to give the company a reputation, and it just so happens that the requirements of our military are similar to our design requirements. ”

"And in fact, a lot of things are ready-made, the core of an off-road vehicle: the engine, the gearbox, the transfer case, the differential, we have also completed the design of the chassis, and now the job is actually to build a shell to enclose these things, and then move two chairs up...... We had the chairs ourselves. ”

"I see." Hearing Lin Hongfei say this, Ding Science suddenly felt a lot relieved.

Well, it's okay to say that, this kid scared Lao Tzu, do you know how scary your kid's words just now are? If you design such an advanced car in a week, if you kid does it, then everyone else will have to die? This is clearly unscientific...... If Ding knew that Lin Hongfei was actually just a temporary idea, he probably really had to die.

"That's a week," Ding Kexue, who felt that he had lost face today, waved his hand and decided to give Lin Hongfei a little difficulty, "At least 10 cars will be taken out in a week, and they will say okay, although it is a rush to work, but our army's requirements for quality are very high, you kid can't use patchwork things to make up the number!" ”

Ding Science's expression is called a righteous speech, but Ding Science, who has a righteous face, obviously forgot one thing: any car is actually a patchwork of various parts, but some people put it together well, and some people's ability to put it together directly fights the five scum.

"No problem!" Lin Hongfei's confidence was a little unusual.

Of course, he has the confidence to say this, for no other reason, not only all the core components have been completed, eliminating the customer's most intuitive, but also the most time-consuming appearance and interior design pain, the most important reason is that as the chairman and chief designer and chief creative engineer of Guqi Provincial Industrial Manufacturing Co., Ltd., there is a team of hundreds of people behind Lin Hongfei to serve Lin Hongfei, this team of hundreds of people, there are carpenters, clay molders, turners, fitters, millers, Planers and other professional technical teams and the most advanced processing equipment and CNC machining centers in China, if it is industrial large-scale production, it is naturally different, but if it is only a small batch, regardless of the cost of the production of a batch of parts and components for assembly, a week is really not a difficult thing...... Do you remember the myth of the development of the P-51 "Mustang" fighter? In fact, the whole process is similar to what Lin Hongfei has to do.

————————————————————————

A week later, at a certain military vehicle test site, I looked at the 10 cars parked in front of me...... Well, the car that was temporarily named Wrangler by Boss Lin Daxue, Ding Science was dumbfounded.

Adhering to the principle of copying the classics to the end, Lin Hongfei unceremoniously took the name Wrangler for his own use.

10 Wranglers. Five of them had regular axles, but even then they had a ground clearance of 26 centimeters, and five of the "enhanced" Wranglers with portal axles and better passability had a ground clearance of 45 centimeters.

The fierce shape and the engine cover cooling window that seems to be still steaming silently show that this guy is very difficult to mess with.

When the facts are in front of you, even Ding Science has to admit that these cars sell very well, at least they look much more pleasing to the eye than the 212 Jeep, the fine workmanship and the hard roof design are enough to throw the 212 Jeep off a few streets, and the two-door design not only shortens the wheelbase, improves the car's passability and off-road ability, but also makes the car suddenly tall.

Of course. Our Minister Ding is not so easy to admit defeat, he snorted, "It looks good, but how it is remains to be verified." ”

"We welcome our fighters to guide us in our work," said a calm smile on Lin Hongfei's face. Looks contented...... Of course, he is confident in his design, "It's the mule that pulls the horse." Did we Lin Hongfei brag and say big things? See the real chapter under your hands! ”

"Don't cry when the time comes." Ding Kexue did not show weakness in his mouth, but he was a little bottomless in his heart, hesitated, he pointed to the five cars that did not use portal axles, and waved his hand to a few soldiers who came to test the vehicle next to him, "Go up and try." It's hard to make, don't save face for Lin Hongfei, a bastard. ”

I say this as if you were being polite to me...... Boss Lin was speechless for a while: If you don't think I can't beat you, I'm welcome.

……………………

This was accompanied by a roar and tremor characteristic of diesel engines. After a while, the 10 cars trembled lightly like excited horses eager to rush to the battlefield immediately.

Taking advantage of this most difficult effort, Lin Hongfei loudly introduced them to the use of this car, "You have all driven a Humvee, right?" I'm sure you've all driven, if you've ever driven a Humvee, congratulations, this car is driven in a similar way to a Humvee, and the position of the main function buttons is basically the same as a military Humvee. ”

"Yes!" A uniform sound blew Lin Hongfei's eardrums buzzing.

Lin Hongfei's words are a bit redundant, even if Lin Hongfei doesn't say so, everyone will do it, special forces cars are completely different from civilian cars, and their requirements for drivers are definitely not comparable to the people, ordinary people can even change a spare tire and can be legally on the road, but as a professional car soldier, not only requires you to repair cars, driving skills are superb, but also require you to repair cars quickly and well.

If you want to drive the car well, familiarizing yourself with the car is the first step, don't look at Ding Science's call, but who dares to conduct various tests without first getting familiar with the car performance, Ding Science can plan this girl's legs...... Are you going to make a joke with your own life? Or are you going to joke with the lives of your comrades?

……………………

Half an hour of adaptation time passed in the blink of an eye, as if it had been measured, and 10 cars were neatly parked in front of Lin Hongfei and Ding Science, as if they had deliberately drawn on the ground with a pen.

Don't look at Ding Science is the hardest, but this guy is much more attentive than Lin Hongfei, and before the car stopped, this guy immediately rushed up and asked anxiously, "How does the overall feeling of the car?" Has the engine been overheating? ”

The air-cooled engine is very good, but the biggest problem with this product is that the heat dissipation is worse than that of the liquid-cooled engine, of course, it is no problem in winter, but what about summer? Will there be thermal decay or even cylinder explosion and cylinder pulling after long-term use? According to the requirements of the Central Military Commission, these vehicles assigned to a certain special force should be used in the northwest desert where the maximum temperature is more than 50 degrees Celsius and the ground temperature is more than 70 degrees.

Well, it's winter, but if the engine overheats in winter, then don't think about it, this thing is directly a first- or third-level cripple.

"Report chief, combined with the use of this half hour, we initially think that the overall car is very strong and stable, as for the engine ......" The major officer led by him hesitated, "Now it seems that the engine is very stable and there is no thermal attenuation, but after all, it is winter, and it still needs to be strictly tested." ”

"Hmm." Ding Kexue nodded.

The engine is stable, there is no thermal decay, which is of course a good thing, but as the officer said, it is winter after all, and everything is not easy to say...... It's one thing for Lin Hongfei to build a car in a week, but the military's tests are harsh and long, and it is conceivable that when this summer, a mysterious convoy will definitely appear in the northwest desert.

"Very good," Major General Ding waved his hand, "rest for 20 minutes, and after 20 minutes, the performance test under various complex terrain conditions will officially begin." ”

"Yes!" The major put his feet together and said loudly, "Rest in place for 20 minutes, and after 20 minutes, you will start passing performance tests under various complex terrain conditions." (To be continued......)
