Super Weapon Exchange System

National defense security cannot be measured by money.

Submarine-launched missiles, as the force of the second nuclear strike, are the last resort of the Five Normals and are valued by all countries. However, for Han, it is unrealistic to build nuclear-powered strategic missile submarines. Funds are all placed here.

Therefore, the landing of huge waves is a low-cost secondary nuclear counterattack force. It is the most important force to maneuver on the ground by the missile launcher and be ready to receive orders from higher authorities to carry out a strategic nuclear counterattack. This task is assigned to the Second Artillery Corps.

Compared with the trailer can only walk on the road, this off-road chassis can pass in any complex terrain, which is obviously a more effective way.

If it can be built, it can be said that it will add a solid shield to the national defense and security of the motherland. The significance of this ballistic missile launch vehicle cannot be overstated.

At the same time, due to the high field maneuverability of this type of missile launcher and the possibility of variants, it is not useless to play a role in oil exploration and other fields.

Now, the northern heavy truck factory has developed and has become a well-known domestic heavy truck company with strong profitability. Therefore, even if the superior has no project or appropriation, relying on the factory’s own funds, the research and development must be carried out. After all, there is a country where there is a home. Without a strong motherland, would there be a strong enterprise?

In the old society before the founding of Han, how many businessmen set up factories in the country with the ideal of saving the country and wanted to rejuvenate the country. What happened?

Those ruling classes will kill them because their existence is not in the interest of the big capitalists abroad. Only when the motherland is strong, will there be the prosperity of the enterprise and the status of the enterprise in the world. Therefore, even if it is the largest in the world, you must never forget that you are strong because of the motherland behind it!

It is an inescapable responsibility to contribute one's own strength to the motherland.

Now, what Qin Guan said, made everyone's heart moved. That's right, national defense security is the responsibility of the enterprise, and it must not care about the gains and losses of the enterprise. Now, it must be done.

"Brother Guan, relying on the funds and strength of our factory, it is possible to complete the imitation of this off-road chassis." Heribala said: "However, we still have many problems, such as its engine, Are we going to copy it as it is?"

The transmission, rear axle, and chassis must be copied as they are. There is absolutely no problem. With the existing processing capabilities of North Industries Corporation, it is no problem to engage these big guys. The main problem is the engine.

Military vehicles, the engine life is not long, the most representative of which is the tank engine, the tank diesel engine is small in size, high in power, high bearing pad pressure and intake pressure, and the mechanical load and thermal load requirements of the engine are relatively harsh. .

In this way, the high-power operation of the tank engine comes at the cost of a high degree of reinforcement, a short service life, and a high purchase price.

For example, the commonly used engine of the 59 tank can output more than 500 horsepower, but it can only use 500 motorcycle hours, and the price is as high as 1 million yuan.

In contrast, the largest diesel engine of the current northern heavy truck can stably output 400 horsepower, and the price is about 100,000 yuan. At the same time, the working time, not to mention 500 hours, 5,000 hours is less. If you maintain If it's good, 50,000 hours will be fine.

Of course, after 500 motorcycle hours have passed, the diesel engine of the tank is not meant to be immediately scrapped and unusable. After the engine is retired from service, it can still be used in oil drilling, geological survey and other fields by reducing its power. Continue to work for 2 to 3 thousand hours.

Military engines have high quality standards, and tank diesel engines with high power, small size and light weight will naturally be welcomed by local units.

And now, this off-road chassis, although Heri Bara hasn't disassembled it yet, I also know that it must use a military diesel engine, and its lifespan will not be very long.

For oneself, if it is simple, you can directly take the tank engine. The improved tank engine can output 600 horsepower without a problem, and the most advanced main battle tank, using the imitation Hans country tank engine, can already Stable output of more than a thousand horsepower.

However, this kind of chassis in front of you is obviously a vehicle chassis. For a car, if the engine is overhauled for 500 hours, it is definitely not worthwhile.

This is the question of how to choose. For Xiong people, they may not care about lifespan, but in Han, it is absolutely impossible to ignore lifespan.

"Our existing diesel engine can already output 400 horsepower." Qin Guan said: "If the cylinder is expanded, can the power reach 650 horsepower?"

Now, this project is only for the country's service. However, if this project promotes technological progress in related areas, it will also make Han's heavy truck technology make another leap and become the leader of the entire world.

Qin Guan supports civil engines. If civil engines can output 650 horsepower, while also ensuring the advantages of economy, low fuel consumption and long life in the field of civil engines, it will definitely drive the heavy truck industry to take off. . In the field of heavy trucks, of course, high-horsepower diesel engines are also needed.

Looking at later generations, we can know that in the 1990s, heavy trucks generally had more than 200 horsepower. After two thousand years, they began to move toward more than 300 horsepower. After that, more than 400 horsepower became the mainstream. When Qin Guan was leaving that parallel In the world, the leading heavy truck has reached a power system of 500 horsepower.

Large horsepower, high speed, high timeliness, and fuel-efficient, similar to vegetable transportation, express delivery industry, all need such a power system, the driver can also save effort, like a car, the accelerator is down, heavy trucks Rumbled up quickly.

When the horsepower is small, it is the old cow breaking the car, slowly dangling.

Taking advantage of this opportunity to get a high-horsepower engine?

In this way, if you want to build a mining truck in the future, you can use it, and if you want to build a large car, you can also use it. It can be said that a high-horsepower engine is still necessary as a technical reserve, which also reflects a A project of the technical strength of the car factory.

The easiest way to increase power is to expand the cylinder.

At present, the main engine of domestic heavy trucks is the imitation of Steyr's WD615 diesel engine. This diesel engine has 6-cylinder in-line, cylinder diameter 126mm, stroke 130mm, single-cylinder displacement 1.5L, and engine displacement 9.726L.

At the beginning, it was naturally aspirated, and the power was increased through exhaust gas turbocharging and supercharged intercooling. The current 400-horsepower model is the most powerful model.

If on this basis, the cylinder diameter is enlarged and the displacement is increased, the power can be further increased.
