"To be honest, I don't think it's good!" Zhang Lan smiled bitterly, "Instead of making the heat dissipation system so complicated, you might as well directly increase the volume of the heat sink, increase the diameter of the heat dissipation fan, find a way to increase the speed of the heat dissipation fan, and increase the heat dissipation airflow through the heat sink to increase the heat dissipation effect of the heat sink!" Excuse me, have you thought about how you can install these two sets of radiators in your car in the future? ”

"Installation?" Hearing Zhang Lan's words, Shiryakov was stunned for a moment, and then remembered a problem he had been ignoring: this cooling system is for cars, not motorcycles. There is no problem with the use of dual radiators on motorcycles, but how to install an extra radiator on a car? Is it possible to install another radiator on the roof of the car? Or is it like a mid-engined supercar, with an additional radiator mounted in the trunk by adding air intakes to the side of the body?

Seems ridiculous! It's an engine for a sedan, not a sports car!

"So what now?" Seeing that the design he had always been proud of had ignored such a major problem, Hiryakov was a little distraught. Well, it's true that this problem hit this guy a bit hard.

"It's simple," at least Zhang Lan doesn't think it's such a difficult problem to solve, and I have to say that Shiryakov's design can sometimes be used, "Calculate that under the existing conditions, how big radiator does this engine need to dissipate heat when the outside temperature is 50 degrees Celsius, and then customize a radiator of the corresponding volume, I think a single radiator is much simpler than a double radiator, right?" It's nothing more than increasing the volume and increasing the fan. ”

That's really the case, Shiryakov thinks, isn't it that simple! It's not a redesign of the engine, it's just a cooling system, it's very simple.

After thinking about it, Zhang Lan added another point, "Sort out the design plan of the heat dissipation system of this dual radiator design and send it to the data room for preservation." Maybe you'll need it sometime. ”

In addition to this slightly frivolous design, in general, the performance of the 1.8-liter engine developed by the Hyakov team is quite good, compared with those engines of the same level in the world. Not inferior to them in terms of performance, this is a good engine.

It didn't take more than a few days to make such improvements to the cooling system, which wasn't too much of a problem and had little impact on the overall progress of the project. Zhang Lan shook her head, a little helpless: Why hasn't anyone found out about this problem for so long? The inevitable result of the disconnect between research and market demand.

This is a similar situation. It seems that it is not only the Soviet Union, China has also made a lot of such jokes in the era of planned economy, the same task, after the various decomposition tasks have been issued, everyone has their own one, and the final result has become a big trouble, and even the things that come out in the end cannot be assembled.

Don't say any people-oriented nonsense, in the final analysis, in fact, it is because you have not been tested by the market, and you have suffered losses in the market. You naturally know what you should do.

Is this a product of socialist characteristics? Zhang Lan smiled wryly as she prepared to go to several other project teams to see the progress of the project.

Fortunately, everything in the other two groups was normal, and nothing happened that made people laugh and cry, and Zhang Lan was finally relieved.

Seeing the unrecognizable test car that was painted in the factory and was being tested at the test site, Zhang Lan couldn't help but go up and take a look, very good, in addition to the mess of deliberately camouflaging the appearance in order to prevent being secretly photographed, the interior was completely in accordance with his previous design, and the buttons on the center console were arranged very neatly. The functions are clear at a glance, so that people who have just driven this car will not feel at a loss, and the joint between the various accessories is also very tight, and there is no gap where your fingers can be inserted; It felt comfortable to sit in.

The only minor problem that is not a problem is that the smell of new cars in the car is heavier. It's a little bit pungent, but it's not a big deal, any new car, there will be some such smell, and it doesn't become a problem when the new car is sold. Fortunately, it is not very pungent and cheap plastic smell, otherwise Zhang Lan would have the heart to cry - if a mid-to-high-end car gives people this feeling. How can this car still be sold?

The engine of this test car is the 2.4-liter V-six naturally aspirated EFI engine developed by Petrovich, using a five-speed manual transmission, the acceleration performance is quite good, the gear is very clear when shifting, and there is a slight sucking feeling that is unique to the manual transmission of high-end sports cars when entering the gear, which feels very good.

Although the suspension system is a little stiff on the whole, it is not an uncomfortable feeling, and it does not affect the comfort of the ride, which can make people clear until the situation under the car, but makes people more confident in controlling the car, and at the same time makes the whole car feel like driving a sports coupe.

The slightly stiffer suspension system has been tuned for another benefit: there is no serious roll when cornering at high speeds. It's not like those fluffy Japanese cars, which feel okay and comfortable when the speed is less than 60 kilometers per hour, but as long as the car reaches 60 kilometers per hour, it feels as if the whole person is about to fly out when it encounters a turn.

The body design is really solid, the chassis is tough, solid and stable, and the body materials are not cut corners in the invisible places like Japanese cars, but there is a bit of a rigorous German car flavor, even if it is a sharp turn at a speed of 90 kilometers per hour, the body does not make a strange "crunch" sound as if it is overwhelmed like a Japanese car. In this regard, the style of Soviet cars is faithfully reflected: no corners are cut in the use of materials, which can be described in two words - solid!

A 2.4-liter engine can have such an excellent performance, Zhang Lan is very satisfied, if you remove all kinds of strange camouflage on the outside of the body for testing, this is a good car that can be put on sale. Among the current domestically produced cars, it seems that all the models equipped with 2.4-liter engines are all foreign cars, right?

None of the domestic cars have an engine of more than 1.6 liters. Even if the Santana 2000 came out a few years later, it was only a 1.8-liter displacement, and if you count the body of the Audi 100 a few years later, the 2.0-liter engine and gearbox of Nissan in Japan, and then the Hongqi sedan with a Hongqi logo, the model with the largest displacement among domestic cars is only equipped with a 2.0-liter engine.

Let those officials know what a real sense of speed is! It's not the Jetta that slows down to 160 miles in half a day and floats so much, or the Santana that climbs to 160 miles in half a day and seems to be able to flip the car with an egg under the wheel, but the Alice "Kirin" car that can easily exceed 220 miles in top speed!

Experiencing this, Zhang Lan has full confidence in the listing of the "Kirin" car, in the era when Poussin sells more than 100,000 yuan, and is still in short supply, these cars that are not known to be many times stronger than Poussin, can they not beat the German devil's Lao Sang and Jetta in the case of taking the upper route?

Well, if that's the case, it's completely necessary for me to go headfirst and die.

I wonder how the bulletproof vehicle design team led by Andrey is progressing now? If the company's products want to become popular, they rely on these baby bulletproof cars of Mr. Andre. Regarding the technical strength of Mr. Andrey, Zhang Lan is naturally extremely relieved, a car designer who specializes in designing bulletproof cars for national leaders, what level is that?

Looking at the Audi A8L "Longxuan" in front of him, which is almost the latest version of the 21st century's big-mouthed type, Zhang Lan suddenly wanted to laugh: I wonder what kind of expression the Audi designers will have on their faces when they know that the things they have worked so hard to design have become other people's wedding dresses? Wrath? Or can't you laugh or cry?

Zhang Lan can't see these bulletproof cars anywhere else, but Zhang Lan can see the thick bulletproof glass clearly, and Zhang Lan smacked his tongue when he saw the thickness: These bulletproof glasses are all imported from Germany, and the price of this batch of bulletproof glass alone can buy a few very good cars.

The semi-solid special rubber tires are also custom-made by Michelin Tyres, which would have been difficult to get without the good partnership between the Alice Motorcycle Team and Michelin.

In addition to special bulletproof tires and bulletproof glass, enjoy the equipment is also first-class, the audio equipment on the car is the world's top audio-visual brand Danish B&O car audio equipment, by Alice (USA) Group specially commissioned B&O for the "Longxuan" car audio system customization, the car is cleverly equipped with twelve carefully tuned speakers, the sound effect is good can make people in the car do not want to get down, The immersive musical experience is completely incomparable to those fool-proof car audio modifications that only know how to install a subwoofer.

In addition to the car audio, the walnut wood decoration on the center console is made of twenty-year-old high-quality walnut imported from the United Kingdom, the leather surface of the seats is also made of the finest Italian tanninned calf leather, and the rear passenger is very cleverly designed with a small car Xiaoice box with a small volume and a small bar with an ice bucket; Coupled with the bulletproof car workshop, these top auto parts designers who specially designed the president's car are made with their dexterous hands, and all kinds of mobile office accessories are top-notch in terms of quality and comfort, giving people the feeling that this is not a car, it is simply a mobile castle with a low-key appearance and a luxurious interior!
