Chapter 130: Can't go up

Qin Guan is addicted to racing.

The Leopard-2 tank gives the impression that it is the Ferrari of a car, which is extremely smooth. No matter what the situation, its chassis will give people a sense of confidence.

However, T-72 is not.

When Qin Guan stepped onto the T-72's cab, he still wore a helmet for tank soldiers, and then pressed the start button.

"Chichichichi." The sound of the compressed air motor came from behind, and the engine emitted puffs of black smoke, but it just didn't start.

what happened?

After starting it twice in a row, Qin Guan didn't start the engine, and immediately became anxious: "This tank is not broken, right?"

This was not exchanged by Qin Guan. It was a state secret exchange from abroad. Will the other party build a broken tank to deal with it? If that's the case, how can it compare?

Qin Guan was confused.

The technicians are also at a loss. Someone has planned to open the rear engine cover to see what happened. Although this is a new tank, its engine is gradually improved from the previous engine.

Qin Guan also planned to crawl out of the tank, and when he looked down, he suddenly found a switch: "I know, I know what's going on."

Although the T-72 tank is improved from the previous engine, it also has its own advanced features, that is, it adds a multi-fuel selection knob.

When on the battlefield, once the tank loses its fuel supply, it is a living coffin. At the same time, because of the difference in fuel, in many cases, even if it is available, it cannot be added.

For example, if the tank uses diesel but only gasoline on hand, what should I do?

Therefore, a multi-fuel hybrid engine appeared, and the current T-72 can use diesel, kerosene, gasoline, and mixtures of these fuels. When there is a real shortage of fuel, even marine heavy fuel can be burned. When using different fuels, the driver needs to control by turning the wheel and adjusting the fuel supply lever.

At this time, the **** was adjusted to the gasoline position, and it was diesel oil that we took for granted.

How to do?

"Clean the oil circuit and refuel." Qin Guan said, "It's really a troublesome thing."

Although it is called a multi-fuel hybrid engine, it is quite troublesome to actually operate. For example, this tank used to burn gasoline, but now it uses diesel, which cannot be mixed and burned. You must first burn all the oil in it. Take it out and clean the oil circuit before adding diesel oil.

It's actually quite tasteless.

Back then, Xiong and Han held a joint exercise. When they drove over, they burned kerosene. Han was very generous to provide them with diesel. As a result, Xiong’s tank soldiers refused to live or die and waited for a long time for their fuel vehicles.

Because they are afraid of trouble, cleaning the oil circuit is a laborious task.

That's it now.

Qin Guan only provided suggestions. At the same time, he introduced to others that this engine can use multiple fuels, but now it is very troublesome.

Several technicians began to work nervously, and it took more than an hour to clean the engine and fill it with diesel.

Although in the introduction, mixed fuels of various fuels can also be used, in actual operation, it is simply a disaster.

"Chichichichi, boom boom boom." Finally, the ignition was successful this time, Qin Guan sat in, pulled the operating levers on both sides, and the tank started to start.

Driving this tank is just like driving a crawler tractor. It is controlled by the operating levers on both sides, and various functions are on the operating levers.

In terms of mechanical device, the engine comes out, on both sides of the car body, there is a 3-DOF planetary mechanical gearbox with the same structure and manual hydraulic control. It has 4 planetary rows, 6 controls, and 7 forwards. Gear, 1 reverse gear, in addition to shifting, it also has functions such as steering, braking and cutting off power.

Now, when Qin Guan wants to drive in a straight line, he needs to shift the gearboxes on both sides into the same gear at the same time. The two steering valve spools on the left and right of the rigid linkage shaft ensure the synchronous operation of the gearboxes on both sides.

In this way, the crawlers on both sides start to start synchronously.

This process is very slow.

The joystick was pulled back continuously, and the speed gradually increased. When the speed was accelerated to 30 kilometers per hour, it took more than 20 seconds.

Qin Guan started the tank, listening to the rumbling sound from behind, it was deafening. He pushed the left lever forward to make the gearbox on the left one gear lower than the gearbox on the right. In this way, the speed of the left track was low. , The right track maintains the original speed, and the tank starts to turn left.

This control requires a lot of technology. Fortunately, Qin Guan was very experienced in the factory.

When driving on that soil slope, Qin Guan didn't have the courage to fly. He stepped on the accelerator to go uphill, and when the front track began to hang in the air, he began to release the accelerator.

"Boom!" The tank fell heavily, with his head on top. If he wasn't wearing a thick hat, his head would definitely be bleeding.

Opening Leopard-2 is a kind of enjoyment, driving T-72 is a kind of torture.

Then, in front of the mud pit, Qin Guan slowly pushed the operating levers on both sides, both in the third gear position, so that the tank has enough speed to rush in, and it will not stall due to low torque. .

But he still has no confidence.

The throttle has reached the bottom, the tail engine is neighing, and the maximum power of 780 horsepower is exploded. The crawlers on both sides are turning in a clatter. The body in front has already got into the mud, and then the engine becomes dull.

Qin Guan pushed the levers on both sides, lowered to 2nd gear, then 1st gear.

The body of the tank has completely entered the mud pit, and the engine has emitted puffs of black smoke, which is obviously already quite difficult.

Fortunately, the tank was still moving forward, and finally, the track in front of it touched the **** and began to rise.

Can you climb out?

"Suddenly." After the last burst of black smoke, the engine turned off.

Going forward in the mud is already its maximum ability. Now it is still going uphill, and it can't be supported at all. In this way, after the engine roared a few times, it completely stopped.

"Chichichichi." The compressed air motor roared and started the engine again. Qin Guan had to try a second time.

Throttle to the end, first gear, rush up!

"Long, Rumbling." The sound of the engine rang for less than ten seconds, and it turned off again.

Opening the top hatch, Qin Guan shook his head, watching the mud almost spread to the car body, "No, I can't get up."

Although there are many factors for whether to go up, there is no doubt that the engine is the most direct manifestation. Now, looking at the tank lying in the mud, almost everyone has an idea. The Leopard-2 chassis is definitely the most reliable. Up!
