Coquettish Rebirth

"Chefeng Millennium Edition 1.3t turbocharged!" Jia Hongjian made a final decision at the high-level meeting of Huaxia Automobile after returning to Shanghai.Today, Huaxia Automobile is a listed automobile group after the integration with Xiang Torch, so such a meeting can definitely be said to be a meeting before the stock price of the listed group soars. The stock of Huaxia Automobile is sure to go up!And since the end of 99, China's stock market has been rising slowly, and it has already risen by more than 2000 points, so it is completely predictable that after Huaxia Automobile announces a new product, it will definitely cause a shock in the stock market .After all, in the current market, Huaxia Automobile can be said to have a relatively single product line, but its product sales are quite large.Even such a company is the company that started the era of Chinese national cars and brought the Chinese people from the era of bicycles and motorcycles to the era of automobiles!Wouldn't the stock market be optimistic about the new products developed by such companies?

And such a product itself is enough to have a gimmick!It also relies on the fuel-efficient and economical route. The Huaxia Automobile is not taking the route of Japan and South Korea at all!What route are Japan and South Korea taking?To put it simply, it is all kinds of soft chant, all kinds of "cutting corners" and all kinds of careful calculation!Needless to say, the thin iron skin covered in Japanese cars is made for the purpose of reducing the weight of the car body and saving fuel.As for South Korea, the route taken is similar. After all, from a certain point of view, South Korea is a student following Japan to learn from Japan's experience.Basically what Japan does.After they learn it, they change their skins, just like their Korean plastic surgery, just make it more beautiful and put it out.

However, Huaxia Automobile is not taking the same route as them. It can even be said that Huaxia Automobile is on par with Japan and South Korea in terms of the number of routes. Heavy, this Huaxia Automobile can think of using aluminum alloy to make the car shell!Although the strength of ordinary aluminum alloys cannot be compared with iron and steel, the aluminum alloy formula used by Huaxia Automobile, or to be more precise, the aluminum alloy they use is the strongest commercial aluminum alloy: 7075!

This 7075 aluminum alloy can be said to be one of the top three aluminum alloys with the best comprehensive index!Even the tensile strength and yield strength of such aluminum alloys.It is as good as the middle and lower stainless steel!Of course.This uses the strongest commercial aluminum alloy, and the price is not ordinary.Let’s not talk about the specific price of the 7075 aluminum alloy, just talk about the cost of aluminum ingots—the cost of one ton of aluminum ingots is 15000 RMB, plus various materials and various processing costs.The price of this 7075 is definitely more expensive than aluminum ingots.After all, 7075 has a different name.That is called aviation superhard wear-resistant aluminum alloy!So this price is considered a super-large-scale purchase, and it will cost about 18000 a meal!

And what about the steel plate?For example, rebar is 2000 yuan per ton, and steel plate is more expensive.But it is not expensive, it is about 4400 yuan!So after doing this, and adding a series of things such as the imported diesel engine and gearbox, the cost of this car will increase significantly!If the cost of a small car such as Bujing 660 can be maintained at 25000 yuan or even lower, then such a wind-cutting millennium version of the aluminum alloy car, because the glass fiber reinforced plastic shell is changed to a more expensive aluminum alloy , so the cost increase is not worth four times as simple as that!So if the price of a small car like QQ in the later generations is about 4, the cost of such a cut wind Millennium Edition will be 20 to [-] to [-]?Wouldn't it cost about [-] to sell it again?So the gap between these two product lines is too big?

Of course not!Want to know what is the density of steel?It is about 7.85, but what about aluminum alloy?That's around 2.75!When Jia Hongjian calculated the price before, it was based on weight!Instead of counting by volume!Counting all the mess in a car, even if it uses a ton of steel, but using aluminum alloy to make a car of the same size, would it use a ton of aluminum alloy?Come on, how about saving gas?The weight is the same, okay?If the weight is the same, assuming that the wind resistance is the same, that is, the shape is the same, then the work done by the engine is the same.If the engine is still the same brand, it means that the fuel consumption should be the same!right?This is the same as the question of who weighs a ton of iron or a ton of cotton. Both weigh a ton, of course they weigh the same!

So if we regard a heavy car as a solid steel ingot.The weight of this steel ingot is one ton, and then such a steel ingot can be hammered and forged into car shells, chassis and so on.Then let's calculate the volume of such a one-ton steel ingot?That's about 0.13 cubic meters.In the same way, if we take 0.13 cubic meters of aluminum alloy and hammer and forge it into the car shell and chassis, how much should the car weigh?The answer is 357.5 kg!Do you see it?That's a weight difference!

And the difference in weight will cause the cost to be not that big!One ton of steel is 4400 RMB, but how much is about 0.36 tons of aluminum alloy? 6480 only!The cost of using aluminum alloy is a little higher than that of steel, but is it that exaggeratedly high?not at all!At most it is 1.5 times that of steel!

Of course, a car is definitely not as simple as a solid steel ingot.For example, domestic cars now generally weigh 1.3 tons. In addition to various steel car shells and chassis, there are various other weights.For example, the transmission system, such as various seats, such as the engine-the engines used in China are basically cast iron now.How heavy is this cast iron thing?Like an ordinary family car, an all-aluminum engine can be used, which can reduce the weight by about 20 kilograms in total compared to a cast iron engine.The 20 kilograms may not seem like much, but after using all kinds of methods, the weight reduction is very objective, and this is also the source of the fortune of Japanese cars!According to foreign calculations, for every 10% reduction in the weight of the car itself, the fuel consumption can be reduced by 6% to 8%.If calculated in this way, a 1.3-ton car, that is, a 1300-kg car, can reduce fuel consumption by 130-6 percentage points as long as the weight of the car is reduced by 8 kg!According to Mr. Guo Konghui's description, the progress of the times brought by Japanese cars in the past 20 years is that the weight of their cars has been reduced by 20% compared with the weight of American cars in the early years!This is why Japanese cars are fuel-efficient!

For the Qiefeng car, Jia Hongjian and the others chose a German cast iron engine.This is mainly because the various characteristics of diesel are different from gasoline. Gasoline is relatively easy to ignite, so the pressure resistance of the engine block is not high, so it can be replaced with pure aluminum or something.As for the diesel engine, that's not the case, so the vast majority of diesel engines in the world are still made of cast iron.But even if a cast iron engine is used, the weight is only 20 kg heavier than a pure aluminum engine!In other places, Jia Hongjian's weight loss is quite obvious!They are now no more than 700 kilograms of the whole car with no load!

Compare it with other small cars - like the Focus sedan of later generations, the empty weight is 1375 kg.Therefore, in terms of empty weight alone, Jia Hongjian's weight is only about half of that of the Focus sedan!And this is the result of deliberately using more aluminum alloy than ordinary steel cars to make cars in order to ensure that the safety performance at least reaches the effect of steel!Therefore, according to the foreign formula, Jia Hongjian and their Qifeng can save fuel by at least 30% compared with the Focus sedan!

And how much does such a car cost?Jia Hongjian didn't lie to anyone. Mr. Guo Konghui and the others calculated that such a car would cost about 10 yuan after mass production! For the price of 10 yuan, if Jia Hongjian is more conscientious, the ex-factory price of 11 yuan, and 12 yuan in hand, is this absolutely great?Isn't such a car a noble car?You must know that the price of Poussin in this era is damn similar to this car!

And what is the fuel consumption of Poussin?According to different road conditions, this Poussin consumes 7-10 liters of fuel, which is normal!And what about the cut wind of Huaxia Automobile?It is estimated that when the road conditions are not good, about 5 gas is already more fuel-intensive!This [-] kilometers can save half of the fuel, and this is only counting the volume, not counting the diesel itself, which is cheaper than gasoline!Moreover, the diesel engine Jia Hongjian and the others introduced can still use vegetable oil and biodiesel!

What is biodiesel?That thing is something that can be extracted from waste oil!The so-called biodiesel refers to the use of various animal and vegetable oils as raw materials, which are modified by lipidation reaction with alcohols such as methanol or ethanol, so that they can finally become a fuel for internal combustion engines!After the oil crisis that began in 1990, foreign countries have already started to develop biodiesel. Otherwise, the German diesel engine factory would not be able to develop this kind of stuff, nor would it be possible to win the European environmental protection award!

In the 90s, no one in China knew what biodiesel was, but with the gradual increase in domestic oil demand and the rise in world crude oil prices, the cost of biodiesel can really be lower than that of refined oil. !For example, in 2012, a meal of finished No. 0 diesel cost more than 7000 yuan, and the price of biodiesel was similar, and it was not uncommon for a meal of cheaper 6000 yuan!Moreover, this thing itself is relatively environmentally friendly, and it is a so-called alternative energy source. If we do this, can't we cheat the state for funding subsidies or something?Jia Hongjian remembered that in 2005, the country decided on some kind of energy law or something, and it was necessary to develop alternative energy sources!

So, at least Jia Hongjian thinks that if he does this, he will really appreciate it in the future-this car can save money on fuel now, and as the price of fuel rises in the future, won't it be more attractive?And this car is fuel-efficient not because of the simple configuration, but because of the use of new technology!new material!At the same time, he is not unscrupulous, like various car manufacturers in the future, an aluminum alloy wheel hub can be so much higher than a normal wheel hub for a small amount of money!And don't forget, it's not that there are no all-aluminum cars in later generations-Lamborghini has produced all-aluminum sports cars!
