Chapter 2869

"This car is a version of our highest configuration." when the car stopped, several people didn't want to come down, and musta wanted to try to drive it himself. Therefore, he ribala exchanged positions with the other party in the car, and then began to explain while commanding the other party to drive.

Musta is worthy of being an old technician. He soon mastered the shifting skills of automatic gear. At the same time, in the driving position, he saw a small screen in the middle of the instrument panel, on which the gear is displayed at this time. In the low gear area, he almost jumps to shift, 1 to 3, 3 to 5, and the acceleration is very fast.

This car has more than five gears.

"Its automatic transmission has 12 gears. When towing 60 tons of goods, it can move forward at a speed of 100 kilometers per hour," the scholar explained.

As a powerful heavy truck with a 420 horsepower power system, on the road, the speed of 100 kilometers per hour is also limited by the on-board computer. No matter how high the speed is, the fuel will be cut off automatically. This is to ensure safety. In fact, it's OK to run for 140. Of course, it's quite dangerous at that time.

Musta was shocked by these data. Nicholas said, "but most of our domestic roads can't run so fast."

Xiong Guo is characterized by relying on railways rather than roads. They have a large number of complex railway transportation networks, and roads are only short-distance transportation. Therefore, there are not many truck roads suitable for running 100 kilometers.

"Yes, but there is one in Western Europe," he zhibala said.

Nikolay's eyes suddenly lit up. Yes, this advanced heavy truck, even Mercedes Benz, man, Scania and so on, these large companies in Europe, do not have such advanced technology. Therefore, if it can be produced, it is possible to seize the market of Hans.

As a big automobile country, Hans has a perfect highway network.

Han's automobile industry developed rapidly. At the same time, it also had a great goal to occupy the European market and march towards the hometown of automobile industry.

This is how much courage and high technology are needed. Now, the Han country has it!

"Of course, considering the cost, our low-grade heavy truck adopts manual transmission, which is matched with 12 and 16 gears," he ribala said.

In fact, the cost is not much. This automatic transmission, called AMT, is only composed of a set of shift components based on the manual transmission. It mainly depends on adjustment. After all, computers are not smart. It takes a lot of effort to make the thinking of computer owners.

This is the cost of R & D.

"At the same time, if we wear hydraulic retarder in mountainous areas, this method can have the ability of auxiliary braking and greatly improve the safety on slope roads." he ribala then introduced: "In fact, in the downhill section, our heavy truck system can be adjusted to the state of no or less fuel injection, which can greatly reduce fuel consumption."

Now, there is no way to change the mechanical fuel injection vehicles. They have been done well, unless they take the initiative to shut down when going downhill. However, after the engine shuts down, the engine can not pump air to the air tank. The heavy truck with pneumatic braking has no compressed air, and the consequences can be imagined.

Only a computer-controlled car can achieve this function. When it is found that the car is pushing the engine, the engine can stop fuel injection and operate completely as a passive machine. On the one hand, it provides braking force and on the other hand, it can continue to drive the air pump and generator to work normally.

In fact, not only on downhill sections, but also on flat roads, if you release the accelerator, the car can stop fuel injection, greatly reducing the fuel consumption rate.

"Is your engine, 420 horsepower, the largest?" musta asked.

He Ri Bala shook his head: "Of course not. In normal road transportation, 420 HP engine is more than enough, and even 360 engine is OK. These two models are mainly promoted by us. According to the existing laws and regulations, they can play a convenient and efficient transportation effect. However, in special fields, such as heavy cargo transportation, we also have special vehicles. For example, our biggest power has been developed It can achieve more than 700 horsepower. "

700 horsepower! This is a civilian engine. The biggest feature of a civilian engine is fuel saving, stability and long service life!

When he ribala's words were heard, musta was immediately moved.

What happens if such an engine is used in military vehicles?

Take their military vehicles for example. The largest output is the maz543 military heavy chassis. This four-axis drive chassis is widely used. For example, the Scud missile, which is famous in this war, uses this kind of launch vehicle. What other rocket chassis and S300 missile vehicle are all of this chassis.

However, I am not satisfied with its power system. It directly adopts a d12a 525A V12 cylinder water-cooled diesel engine with a displacement of 38.9 liters and a maximum power of 386 kW. You can see from the number that this is a tank engine.

The service life of tank engines is only 500 hours. After equipping troops, it is absolutely a huge waste to overhaul or replace engines after 500 hours. If civilian engines are used, the engines do not need to be operated for 100000 kilometers, and the fuel consumption rate is still low. Even military vehicles don't care about fuel consumption, but under the same fuel tank, One tank of oil can double the distance, which means that the long-distance mobility is greatly increased.

The military engine is the result of squeezing power, so its service life is very short. It's amazing that the Han people can develop this kind of engine without squeezing power.

"Director he ribala, I think we can have some cooperation," musta said.

"Yes, we came here with sincerity of cooperation." at this time, the car has turned around and returned to the starting point again. Looking at the waiting crowd below, he ribala said: "We intend to take Mars factory as a partner of our North heavy truck factory to export our automobile technology and produce advanced heavy trucks here to occupy the European market."

Nikolai on the back sleeper also showed a smile on his face. Yes, this is actually the meaning of their industry department. Naturally, they also hope to have a loud fist product in the white bear country, which can be used as an important product for their export and foreign exchange earning.

This heavy truck can certainly undertake this mission!

"Let's go down and talk about it in detail," said Nikolay.
