Everyone burst into applause. The Black Panther diesel engine was operating for the first time. Even if it could not meet the power requirements today, as long as it could be successfully started, it would be a major breakthrough!
"Idle and check the situation in each part." Wu Ruihua shouted.
In fact, if it is in the army, it is not uncommon for the driver to step on the accelerator to the bottom after it is started. In the army, equipment is used to build and must be durable. For example, it may need to start during battle.
After that, I drove immediately. If I didn't drive, the shells flew over the next second.
But now it's a test drive, so it must be safe. So, in front of everyone, this engine is still in the idle speed of 800 revolutions per minute. In this state, the Black Panther engine is running smoothly
Then, the sound of the high-pressure oil pump made was even more crisp and pleasant.
The turbocharger is almost not involved at this speed, which is also the biggest difference between a turbocharged engine and a mechanical supercharger. At low speeds, the exhaust pressure is not high enough, so the supercharger cannot blow up.
If you want to improve performance at low speeds, you need to add a turbine with a small inertia, that is, the blades of the turbine should be smaller, so that the turbine can intervene earlier.
In later generations, many automobile engines were trained in this way, so that they could output power earlier. However, at the same time, because they were small turbines, after reaching the high speed range, if they wanted to continue to increase power, they would be powerless.
Small turbo, the engine explodes early power, and the power attenuation will also be early. For cars, this kind of training is beneficial, because many drivers drive the car until it is scrapped, and they are reluctant to step on the accelerator, and they want to idle the whole process, and then
It's a big cry for a broken car.
However, tank engines are definitely not suitable. On the one hand, tankers have long been used to stepping on the accelerator and leveraging the maximum power of the engine. If you want to drive the tank at idle speed, it is not a problem of cursing the engine meat, but it is not a problem of driving the engine at all.
Let's get the tank.
So, when idle, that is when parking. At this time, the turbocharged engine has an advantage. If the turbocharger does not intervene, it is a self-priming engine. At this time, the engine has only two powers.
At the same time, the turbine does not intervene and the engine fuel injection will not increase. At this time, fuel consumption can be reduced. When parking and standby, the lower the fuel consumption, the better.
This advantage is also unique to piston engines. If the gas turbine used by Americans is low-speed and high-speed, and fuel consumption is no different, they may consume all the precious fuel when they stop.
The engine continued to operate smoothly, and all kinds of data were normal. Then, Wu Ruihua continued to issue an order: "Elevate to one thousand revolutions!"
As the speed increased, the turbocharger began to intervene, and a whizzing sound came, and the power also came. If the power output was drawn with a curve, it would be in a period of rapid climbing.
"Increase to one thousand two hundred revolutions!"
"One thousand four hundred turns!"
When it reached 1,600 revolutions, the turbine began to whistle-like whistle-like squeals. The exhaust gas discharged from 12 cylinders was blowing the turbine blades and told the rotation that the speed had reached tens of thousands of revolutions! The continuous air was
The cylinder was bulged into it, and fuel was injected. In the cylinder, violent combustion occurred again and again, and the exhaust gas was getting hotter and hotter.
"It has reached eight hundred horsepower!" someone shouted happily.
So far, the largest engine in China, developed by the Coal Province Diesel Engine Factory, can only output 730 horsepower. Now, this engine of our side has surpassed that of the Coal Province Diesel Engine Factory!
"Elevated to 1,800 revolutions!"
The speed continued to increase, and the power was still soaring. At this time, there was a special smell in the air, as if something was burning.
That is the result of the turbocharger's shell being scorched by high temperatures!
The speed increased to 2,000 rpm!
The engine continued to run smoothly, reaching two thousand rotations, and you can see that the entire turbocharger had turned red, as if it was taken out of a steelmaking furnace. This look was quite scary.
This won't happen to the supercharger, it is driven by the crankshaft. Now, exhaust gas turbocharger relies on the exhaust gas discharged from the engine to drive the turbine blades. As the speed increases, the exhaust gas discharged from the engine
It will also get higher and higher, but in fact, it is the same as the exhaust pipes of many engines being burned red.
None of the exhaust pipes of the engine does not rust, because they are constantly burned red during work and then cooled, and they continue to go through this process back and forth.
"One thousand horsepower! The power has been increased to one thousand horsepower, we succeeded!" Wang Erzhu looked at the display on the test drive table and shouted loudly: "We succeeded!"
Success!
At this moment, the entire test workshop was boiling, countless people were cheering, and some people's eyes were wet.
The first-machine factory completed an innovation, and for the first time in China, the power of the tank engine was pushed to 1,000 horsepower! For this engine, they worked day and night, and they overcome all obstacles. They didn't know how many difficulties they had overcome, and how many failures they had experienced.
.
They were confident in the first test drive because they had made a lot of preliminary preparations!
Now, the turbocharger has been burned red and is still working steadily. Looking at this scene, Mia also sighed and said, "You are so bold!"
"In order to achieve higher power, we must try it." Qin Zhenhua said: "We use aviation materials, which should be able to withstand it."
If you want the turbocharger to perform more performance, you can get it as close to the exhaust pipe as possible. Therefore, the turbocharger of this engine is specially designed and shortens the length of the exhaust manifold.
It is very close to the engine cylinder, so it is normal for the exhaust gas to burn red.
No wonder they can output 1,000 horsepower at two thousand revolutions, and they are not taking the ordinary path. It would be strange if the efficiency of this turbocharger is not high.
At this time, the speed of the turbocharger had increased to more than 20,000 revolutions, and the whistle-like whistle echoed throughout the workshop.
The bearings of the turbocharger are undergoing forced lubrication and specially designed intercooling devices to cool the intake. The entire set of devices is operating smoothly.
