However, one detail that Zhang Lan noticed was. The volume of the two airbags in the front door is significantly larger than that of the two airbags in the rear door, that is, the buoyancy provided by the two airbags in the front is greater than that provided by the two airbags in the back.

Considering that the front of an off-road vehicle weighs significantly more than the parking space, and the center of gravity tilts significantly towards the engine compartment when the car is in the water, it is clear that it is absolutely necessary to provide more buoyancy to the heavier front of the vehicle. The larger volume of the first two airbags and the tester just fixed the front two airbags with the front bumper of the car, in order to ensure that the front of the vehicle will not be too heavy and unbalanced and plunged into the water, so that the car can ensure that the center of gravity of the car is as stable as possible when floating...... Even if the center of gravity is unstable, it is mandatory to make it stable.

However, Zhang Lan's brows were still tightly wrinkled at this time and did not let go: even so, it was still not enough, the first two airbags had only one fixed point on the body, and when the center of gravity of the car was shifted, the extremely light airbags would be forced to move to the lighter center of gravity under the pressure of water, which seemed to be impossible?

At this time, the bundle of something similar to a stainless steel pipe that the tester had just made was also completed, and it was neatly placed aside.

After taking a closer look, Zhang Lan saw clearly what the bundle of things similar to stainless steel pipes was: after the combination was completed, it turned out to be 8 stainless steel pipes of different lengths screwed together with the stainless steel materials just now, the long ones were more than 5 meters long, and even the short ones were 3.5 meters...... It's long and sturdy, but I just don't know what it's for. One thing is certain, though, that this thing is definitely not used to sit on the roof of the car while it is floating in the water.

After all four airbags were fully inflated, the tester went down and fixed the four airbags on the rear bumper and the front bumper respectively, so that each airbag, which was originally only hidden in one fixed point in the door, now has two fixed points, which is indeed much more stable than before.

But...... Zhang Lan's brows, which had been frowning just now, finally stretched slightly, but then he frowned slightly: Are you ready to float now? This is fine, but under the pressure of the water, the four flat-oval airbags will go from lying flat to upright and tightly attached to the door.

Although it can still provide enough buoyancy for the car in this case, there is no doubt that the degree of water ingress in the car is very strong, and it is conservatively estimated that if you start floating like this, the water depth on the floor in the car will be at least about 30 cm, Xiao Chenxi should not make such a simple mistake, right? Not a lot of words

After fixing the airbag first, the tester quickly connected the metal rod of different lengths to the sturdy luggage rack on the roof of the car, and the other end was fixed on a fixed buckle on the outermost side of the airbag. Two stainless steel connecting rods are used to connect the outermost side of the airbag to the sturdy luggage rack on the roof.

Fainted, it turned out to be a way to provide more buoyancy, when she saw this, Zhang Lan finally suddenly realized, and at the same time was amazed by Xiao Chenxi's whimsy.

To give a more vivid example, it is like the lever used to fix the auxiliary fuel tank on the outside of the Mi-171 helicopter, but it is different from the lever used on the Mi-171 helicopter. The pull rod used on the Mi-171 helicopter is more to provide an upward pull force to the bracket of the fuel tank to reduce the downward pull force of the fuel tank to the bracket, while the pull rod on the off-road vehicle ready to float provides a downward pressure to the airbag to ensure that the airbag will not be able to provide the maximum water contact area under the pressure of water, and a larger water contact area can provide greater buoyancy, so as to force the airbag to "lift" the heavy body and let as little water enter the car as possible. …,

Moreover, the airbag fixed with eight metal rods has another advantage, that is, there is a certain elastic margin between the airbag and the connecting rod, which can ensure that the vehicle can reduce the wear of the stainless steel fixed connecting rod on the fixed part of the airbag when there is a large wave on the water surface. At the same time, the bulging airbag is also vigorously supporting the stainless steel connecting rod outward, and the airbag gives the stainless steel connecting rod an outward thrust, so that people will not worry about the stainless steel connecting rod breaking under the upward thrust of the water to the airbag.

When the tester prepared all this, Zhang Lan looked at the watch, the whole preparation process was less than 30 minutes, which is still the speed when the tester is busy alone and no one cooperates, if someone is busy with the tester, the speed is even faster.

That is to say, as long as it is a little prepared, the car can complete the preparation of the pontoon, and the next thing to see is whether the car can successfully complete the pontoon.

The only troubling point is that the hapless driver cannot enter the driver's seat through the door on the driver's side at the moment. There are only two options for the driver to get into the car, one is to get in through the window that has just been lowered, and the other is to open the rear tailgate of the car and get in through the rear tailgate. However, getting in through the rear tailgate and then climbing into the driver's seat doesn't seem to be a good option, especially if you're carrying a lot of gear and supplies in the back.

Under the gaze of Zhang Lan and Xiao Chenxi, the tester got into the door from the driver's seat side of the glass just now, and the car suddenly drove into the water, and the huge airbags on both sides of the body responsible for providing buoyancy floated steadily on the water surface to provide huge buoyancy to the six-wheeled off-road vehicle with an astonishing weight of 3 tons, and the six wheels rotated together with the paddle wheel that played the role of a propeller installed on the six wheels. Unexpectedly, such an off-road vehicle, which has reached 3 tons of weight, floated abruptly on the market and drove towards the opposite side.

At this moment, according to the estimate of how much the paddle wheel is exposed to the water, Zhang Lan visually measured that the wading depth of this car will not exceed 40 centimeters, that is, there is only a layer of shallow water with a depth of about 10 centimeters on the floor of the cab, and the visual inspection of this off-road vehicle at this moment is at least 7-8 kilometers per hour on the water, although the speed is not very fast, but it is also faster than the speed of human walking.

This speed of water travel has even exceeded the water speed of the 92-wheeled infantry fighting vehicle currently equipped by the domestic military, and the water speed of the famous BMP infantry fighting vehicle is on par with the water travel speed of the famous BMP infantry fighting vehicle.

Zhang Lan was dumbfounded! For those who are working in the field, when they encounter a river blocking their way, and they can't find a bridge or shallow water to pass through up and down, they don't have to look at the river anymore...... Perhaps the Brahmaputra River should be excluded, although it is also called a river, but it is estimated that not all ships can travel here.

"How?" Xiao Chenxi was a little proud.

"Awesome!" Zhang Lan couldn't help but admire: such a simple solution can make a car float on the water, why has no one thought of such a simple solution before? One by one, they all worked the shape and sealing of the body. As a result, there is not a single mass-produced amphibious vehicle in use, and empiricism and inertia of thinking kill people.

"I designed this car to be able to float in the case of tripolar sea conditions and can travel stably at a speed of 8 kilometers for 8 hours," ...,

Zhang Lan was taken aback, it was very simple, eight eight sixty-four, which meant that this car could even cross a strait with a width of 64 kilometers, and there was absolutely no possibility for ordinary inland rivers and lakes to stop this car from moving forward.

On the opposite side of the pond in the distance, the tester had suddenly driven a "bloated" off-road vehicle ashore and was disassembling the floating equipment on it, but in Zhang Lan's opinion, the car was like wearing ... The sexy beach girl in the swimsuit is generally seductive, and people can't help but feel sexual.

――――――――――――――――――

However, it is clear that the test work cannot be left alone, and after the morning test work, there are more demanding tests waiting for the car in the afternoon.

"After the test, in the vehicle ignition start experiment in the low-temperature environment that has just ended, the success rate of one-time ignition of the vehicle was 96% until the temperature of minus 25 degrees, and the second ignition was all successful; The success rate of the first ignition at minus 35 degrees is 90%, and the second ignition is all successful; The success rate of the first ignition is 86% at minus 45 degrees, the success rate of the second ignition is 98%, and the three ignitions are all successful. The low-temperature environment simulation room was opened, and the tester responsible for testing the low-temperature starting performance of the vehicle said to Zhang Lan excitedly. The test item sheet in his hand kept waving at Zhang Lan excitedly,

"Boss, I've never seen a diesel engine with such good start-up performance in a low-temperature environment! Even a tank with a glow plug can't achieve such a good starting performance at an ultra-low temperature of minus 45 degrees, which designer designed this car? admires him to death, and I will definitely talk to this guy another day. ”

"Huh?" Zhang Lan was obviously a little surprised by this result.

For diesel engines, although in terms of applicability, diesel engines with large torque output capacity are the most suitable engines for off-road vehicles, after all, the places where these cars work in the field are not suitable for you to run at high speeds, but strong torque output capacity in many terrains is a must.

Although the power output of diesel engines is not as large as that of gasoline engines under the same displacement. But this is not the most important for off-road vehicles, among the most important torque indicators for off-road vehicles, the torque output of the diesel engine under the same displacement is more than double the torque output of the gasoline engine!

In addition to the rough working mode of the diesel engine and the unbearable loud noise, a very important reason is that the diesel engine is a big problem when it starts in winter, and low temperature start has always been the weakness of the diesel engine.

This is where the diesel engine makes many off-road vehicle designers have a love-hate relationship with it: I can put up with your huge working noise and vibration, and I can still solve these two problems if I think of a way, but the car can't start at low temperatures, it's too bad!

Of course, this is not all the problem of the diesel engine, it is not easy to start in a low temperature environment, to be more precise, it is more about the characteristics of the diesel itself, because a significant physical property of diesel is that it will solidify when it is lower than a certain temperature, which is commonly known as diesel wax.

Diesel solidification and wax formation in the low temperature environment in winter has always been a headache for all diesel engine researchers, how to solve the problem of low temperature start of diesel engine and diesel solidification has always been a problem that experts have been trying to explore, and to solve the problem of diesel wax, the problem of low temperature start of diesel engine has been solved for the most part.

Although the existing diesel label can reach a minimum of -50#, the diesel sold on the market is basically 0# and -10# diesel, and -35# and -50# diesel are basically extremely difficult to buy. In winter, it's good to say that if the temperature is higher in the south, but if it's in the north, especially in the wilderness, you may not be able to buy even 0# diesel, where do you buy -35# or even -50# diesel? …,

But now this car can basically ensure a one-time ignition success rate of 86% at an extremely low temperature of minus 45 degrees, which means that in the future, the diesel engine will be the same as the gasoline engine, as long as the gasoline engine goes, the diesel engine can also go, among them, the engine and diesel preheating system and high-performance thermal insulation fuel tank have contributed to this:

In the simulated environment of zero degrees, fill the high-performance insulated fuel tank with a tank of -10# diesel, and then put the car in a low temperature environment of minus 40 degrees, and the temperature in the fuel tank measured after 24 hours is only minus 3 degrees, which is enough to ensure that the diesel in the fuel tank provides fuel for the diesel engine normally.

At this time, Zhang Lan had already forgotten the excited and somewhat incoherent request of the tester just now to meet with the designer of this car, that is, with Xiao Chenxi...... Or maybe this guy said that, he was just excited and didn't know what he was talking about.

"Have you figured out the name for this car?". It was only at this time that Zhang Lan suddenly remembered that this model, which was so unusual in shape and structure that it did not belong to the Alice brand or the Longxuan brand, did not seem to have a name until now.

"Not yet," Zhang Lan didn't have a problem with her memory. Xiao Chenxi was stunned, this girl also ignored this question. But obviously, such a question is nothing to Xiao Chenxi, the little girl lowered her head slightly and thought about it, "Since we say that this car is the king of off-road, why don't we call it king?" ”

“king？ King? Good! Zhang Lan pondered for a while, nodded after thinking and made up his mind, "It's called King, and this car will be the well-deserved king of all cars in the off-road vehicle world." But in that case, we might as well separate this brand and design this car as an independent off-road vehicle brand that represents high-performance off-road vehicles. ”

"As for the car logo, this car starts with an independent car logo, the design style of the car logo is based on domineering, majestic, and in line with the design style of the king, not only to launch such a car, in the future we will build the king series of models into a car series, specializing in high-performance off-road vehicles, so that people hear the name king, they immediately think that the car under this brand is the best off-road vehicle in the world. I don't think my dad and mom will have any opinions. ”

"That's good. Why don't you belong to the Longxuan brand and become a sub-brand of the Longxuan brand," Xiao Chenxi naturally had no opinion on Zhang Lan's proposal and nodded, "This can not only reduce the pressure and resistance of the early brand promotion, but also establish the image of this high-end luxury off-road vehicle brand." ”

"Good idea." Zhang Lan immediately nodded in agreement: Why didn't she think of it just now?

King, the most powerful off-road vehicle in the field of civilian off-road vehicles, a legendary brand of off-road vehicles whose performance even surpasses many military off-road vehicles in the world, represents the symbol of the ultimate performance of off-road vehicles, and finally began to gradually reveal its hideous and sharp minions.

――――――――――――――――――

Not surprisingly, in order to fill the vacancies of the Mitsubishi Pajero off-road vehicles returned by various government departments in China, the snow leopard off-road vehicles of Alice Group have won the vast majority of the orders with their outstanding off-road performance, good after-sales service, numerous service outlets, low late-use costs and moderate prices, a total of more than 40,000 orders for more than 40,000 vehicles were strongly obtained by Alice Group 29,000 vehicles, and the remaining orders of less than 12,000 vehicles. In order to balance the interests of all parties, it has been carved up by large international automobile manufacturers such as Volkswagen, General Motors, Mercedes-Benz and Toyota.

Another unsurprising fact is that although Mitsubishi Motors' Pajero model was successfully shortlisted, in the end, not a single car was ordered. Although everyone knows why, and everyone is grateful for the kindness of Mitsubishi Motor Co., Ltd., which "does not benefit self-interest, but only others", and issued a large number of good person cards to the person in charge of Mitsubishi Motor Co., Ltd. who came to participate in the bidding meeting, the schadenfreude in their hearts is real. …,

As a Japanese car, the Japanese car, which has always been the largest purchase target of the Chinese government's off-road vehicles, has suffered an unprecedented blow this time, and it has only given Toyota an order for 1,000 Toyota Land Cruisers in terms of balancing interests. In the past, Toyota Land Cruiser with its excellent off-road ability, excellent ride comfort and stability has been the first choice in many harsh conditions in our country, this is this time Toyota is very unlucky, affected by Mitsubishi, Toyota in this luxury feast only symbolically got a little "insignificant" order.

The root cause of all this is naturally Mitsubishi Motors, and it is said that after the bidding meeting, the head of Toyota returned to the hotel and fell wildly for a while, mixed with the unintelligible Japanese bird language. As for the meaning of bird language, according to the waiter who was cleaning up in the corridor at the time, it seemed that he was greeting the female compatriots of the family of Yoichiro Okazaki, the president of Mitsubishi Motor Co., Ltd., from 80 to 4 years old.

However, all this noise is not the focus of this bidding meeting, the most striking thing about this bidding meeting is that Alice Group took this opportunity to launch this six-wheeled off-road vehicle named King under its own Longxuan brand.

To be honest, when this odd-looking and huge car appeared on the scene, many people still scoffed at this car, but when the people from the Alice Group drove this car to do a small off-road ability experiment, the audience had become silent, and all foreigners felt that their backs were cold: Is this car still TM a car? It's a light armored vehicle! If I don't take you to play like this, if you play like this, what will we play in the future?

These foreigners already have a bad premonition in their hearts, and this premonition is the most important to the representatives of Mercedes-Benz who participated in the bidding meeting: the off-road performance of Alice Group has even surpassed that of Mercedes-Benz Unimog's off-road vehicle, which is very likely to be the biggest test encountered by Mercedes-Benz in the field of high-end off-road vehicles.

And the fact that this car can be named King by Alice Group also shows the ambition and hope of Alice Group: this car will become the king of the world off-road vehicle world!

However, although these foreigners are concerned in their hearts, the Chinese staff are ecstatic: especially when they see these two strange-looking off-road vehicles actually play floating on the water after a little preparation, this ecstasy reached its peak!

Two weeks later, after a comprehensive evaluation of the Longxuan-King, the government immediately placed an order for the Alice Group to purchase 100 Longxuan-King off-road vehicles. One of the additional notes in the order is particularly eye-catching: the government will increase the order according to the situation.

That is to say, as long as it is good in the process of use, there is no defect that has not been found before, and the government will not hesitate to increase orders.

Alice Group immediately announced that Alice Group will provide the country with 100 Longxuan-King off-road vehicles equipped with many special functions of cockpit pressurized function lights, and in order to thank the country for its support to Alice Group over the years, it will donate 100 Longxuan-King off-road vehicles with the same configuration to the geologists working in Xinjiang, Tibet and the western plateau of the country, so as to effectively improve their field working conditions.

For a time, there was a lot of discussion in the society, and many off-road vehicle enthusiasts were discussing the new weird off-road vehicle launched by Alice Group, and the Longxuan-King off-road vehicle of Alice Group has not yet been introduced to ......the market, which has caused extensive discussion in the society.
