The same 1,000-horsepower diesel engine feels different from the 1,000-horsepower diesel engine of the Eastern powers, and this horizontally opposed two-stroke diesel engine, although the horsepower has been reached, but the torque is not high.

In fact, horsepower is related to the speed, only when the throttle is stepped on to the end, the engine speed reaches the highest, the horsepower is the largest, don't look at the front of the car stuffed with a 200 horsepower engine, but usually reluctant to step on the accelerator, in fact, the power is only 20 horsepower.

Horsepower is obtained at the highest speed, so it determines the vehicle's top speed ability, how fast a car can run in the end, it depends on how much horsepower it has, for the tank, the same is true, a thousand horsepower, can make the tank reach a top speed of more than 70 kilometers per hour, however, 500 horsepower, at most can only make the tank drive to 50 kilometers per hour.

What really determines the speed of the tank is the torque, the characteristics of the turbocharged engine, is to let the torque come earlier, in this way, the speed of the vehicle will be more rapid, of course, the disadvantage is that when the turbo momentum comes up, you will feel a sudden jump, the sales of the car will explain it as a push back feeling, in fact, many turbocharged models are criticized, it is the sudden acceleration brought by the turbo force, the ride and the self-priming engine is incomparable.

For the tank, if you want to squeeze the potential, you have to rely on this supercharger, and the boxer engine is no exception, but the unique structure of this boxer engine determines its lack of torque.

Even the later 1200 hp 6TD-2 diesel engine has a torque of only 3200 Nm, which is even inferior to the torque of the 780 hp diesel engine in the T-72 tank.

This is actually a helpless choice, horizontally opposed engine, a cylinder has two pistons in it, moving to both sides at the same time, so, its cylinder is very long, if the connecting rod is also lengthened, it will lead to the overall size of the engine is too large, can not meet the requirements.

For the engine, the longer the connecting rod, the greater the torque, this is a basic principle of physics, in order to cram into the small engine compartment, this engine has made a lot of compromises. In terms of speed, it is half a beat slower, and at the same time, it is estimated that there is also a relationship with the gearbox, in short, the overall power system, I feel that it is not very easy to use.

Therefore, in terms of speed, it will be half a beat slower, Wang Erzhu's foot has stepped on the accelerator to the end, black smoke is emitting from the tail, and the tank is moving forward in a roar, and then, hang up the second gear, continue to speed up, third gear, fourth gear.

The tank was in the test site, and it started moving, puffs of black smoke came out, and the tank kept moving forward with bumps.

Wang Xiaoyu put his eyes on the sight and looked at the field of vision inside, although the tank was jolting, the image inside remained still, from the perspective of the fire control system, it did a good job.

The laser rangefinder began to emit infrared rays, heading towards the target in the distance, although it was the first contact, but Wang Xiaoyu could skillfully operate the tank's fire control system, her face was full of seriousness, full of concentration, and began to prepare before shooting.

"Coach bounce one, reload."

With the slogan, the autoloader maneuvered, the two of them were on the left and the other on the right, and the place inside was quite narrow, and the autoloader in the middle made a bang and moved.

The main component of this automatic loader is the lifting arm, and its main principle is the "two-stage crank slider" mechanism, the projectile body is fixed to the rocker arm, and the cartridge acts as an intermediate link. In this way, the spatial position is moved.

Qin Zhenhua looked at the automatic loader beside him, and was a little nervous in his heart, this is not an automatic door in later generations, it can be pinched, if it is accidentally extended into this mechanism, it can cause a tragedy all of a sudden.

He looked at his wife with concern, and after making sure that she was fine, he paid attention to the automatic loader again, only to see that the bullet arm rotated around a horizontal axis, and the "four-wheeled trolley" mechanism at the front end was stuck under the horizontal magazine of the "hinged segmented magazine".

Then the arm continues to rotate, and finally completes the movement of the warhead and cartridge. Now, the L-shaped warhead and cartridge have become horizontal, and the bullet arm lifts the shell to the back of the breech, with the warhead in front and the cartridge behind.

At this time, the gun was already in place.

Different from the two thrust projectiles of the T-72, if you compare, this design can theoretically increase the rate of fire, after all, when the T-64 was developed, the Soviet army put forward high technical requirements.

However, if it is about reliability, Qin Zhenhua still likes his own two pushes, the mechanisms are parallel, which is more convenient, and now this kind of thing has to be folded once in the middle.

However, the person who designed this set of institutions also took a lot of painstaking words.

"The target has been targeted."

"Fire!"

"Boom!"

At this moment, the whole body of the tank is shaking due to the recoil, if it is the first time to sit in the tank, you will definitely be scared half to death, this kind of movement, it is simply a landslide.

Wang Xiaoyu is very natural, she has long been accustomed to this kind of movement, her eyes have been staring at the sight, looking at the trajectory of the shell, this kind of training bullet in flight, crossed a clear trajectory, and then, hit the intended target.

Hit?

Seeing this scene, Dulaba in the rear also sighed, he didn't give any explanation, the other party was a woman, after going up, I thought it was just a pleasure, who would have thought that I actually had a real ability, and I could hit the target with one shot!

Of course, he didn't know that when the big eastern countries were renovating the T-72 tank for the oil country, Wang Xiaoyu didn't know how many times he had tried it, although the fire control system models of the T-72 and T-80 were not the same, but they were also similar.

The first shot hits the target, and then the second shot.

Compared to the first shot, it has an additional step to remove the shell.

The T-72's shells were thrown directly outside the turret and littered, while the T-80 had an additional recovery process, and when the second shell came up, the empty shells were placed in the empty barrel.

Wang Xiaoyu aimed at the target steadily, and then fired a second shot.

"Boom!"

"Boom!"
