The red oil barrel was sent to Pogba's hands. Pogba picked up the oil barrel and poured the fuel into the fuel tank beside him.
During the transportation process, the fuel tank and the engine are separated. For the convenience of transportation, there is no fuel installed. Now, after pouring the fuel into the fuel tank, Pogba began to prepare before starting again.
.
If it is a gasoline car, the fuel will be burned out, just refuel it. However, the diesel engine cannot. After the fuel of the diesel engine is consumed, air will enter the oil circuit. From the fuel tank to the high-pressure oil pump, exhaust is required to be carried out.
Generally, there is a special manual exhaust valve on a high-pressure oil pump.
Now, Pogba began to turn the manual exhaust valve there again to let the air in the diesel discharge. After a while, he finally said to Pierre: "The preparations are done."
The crowd around had already spread out a large circle under the organization of the security guards, fearing that their engine would have malfunctioned. However, at the same time, more and more people were surrounding here.
Everyone likes to watch the fun. With such fun, it will certainly attract countless attention. At this time, they are all waiting for the start of the French engine.
The French are proud. Their tank engine is unique and reflects the strange thinking of the French everywhere.
In this era, it is not easy to build a turbocharger, and a high-efficiency turbocharger is not so easy to manufacture. An important indicator of a turbocharger is the average effective pressure, which increases the price of the turbocharger.
The air pressure can be, directly determines how strong the engine's performance is.
The French own tank diesel engine is UDV X series, with a single cylinder displacement of 2.06L and its maximum speed is 2500 rpm. If you take an ordinary road, even if it develops into a 12-cylinder engine, the supercharger must be effective even.
The pressure reaches 2.14MPa.
How difficult is this indicator? In the 1980s, only Americans used composite boost technology to achieve an average effective pressure of 2.32MPa on AVCR1360. However, this is just the data in the laboratory. Because the production is too difficult, this model
The engine was voluntarily abandoned, and the XAV28-1450 then reduced the average effective pressure index to 1.81MPa. The current German Leopard-2 tank engine has an average effective pressure of only 1.754MPa.
Now, by using this turbine engine, they can achieve a power of 1103KW in their 8-cylinder 16.72L displacement, and its supercharger achieves an average effective pressure of up to 3.22MPa, in this era
It is definitely a terrifying data.
Now, the preparations have begun, and the engine is started in sequence. The first one to start is the turbocharger with model TM307B.
Let you hear the sound of the engine!
Just like when those aircraft engines start, when the nine-kilowatt start motor starts roaring, the entire exhibition hall is attracted by the sound. When you sleep in the middle of the night, you hear those motorcycles that explode.
This is how it feels.
Like a whistle, the start of this turbocharger is stimulating everyone's eardrums. Its speed has quickly climbed and soon reached its rated 40,000 revolutions.
The composition of this turbine is not complicated. It is a first-stage centrifugal compressor in front and a second-stage axial flow turbine in the back. The characteristic of this turbine is that it can work independently.
In this way, it can be used as an auxiliary power system to drive the operation of various equipment before the diesel engine is started. At the same time, it can also assist in the start of the diesel engine under cold conditions.
Ordinary superchargers are connected in series on the engine, so that there will be no problems of air intake mismatch and lag of ordinary supercharged engines. The two work in parallel, and part of the compressed airflow of the supercharged device enters the engine.
Part of the refueling device is carried out. The combustion exhaust gas drives the power turbine of the booster device together. When the engine changes, it is necessary to adjust the air flow into the engine through a bypass valve to achieve matching.
Therefore, this device is much more efficient than an ordinary supercharged engine.
Just like this whistle-like sound, the independent turbine started. After starting, it was supposed to start the diesel engine. However, just a few seconds after the whistle sounded, a puff sound came, and then, the whistle
The sound is gone.
Incredibly, their turbines went off after starting.
As long as the turbine engine is started, it can work stably and reliably. No matter how the load changes, it will not be easy to shut down. When it is found that the engine is gone, several people are shocked.
What's going on?
Qin Zhenhua smiled there: "It's gone, everyone has all gone, have you seen it? This thing is still useless!"
"That's right, it's not even possible to work stably. In this turbine, the air intake and the turbine do not match?" Dr. Wright also smiled on his face: "It's not that simple to want to build a miniaturized turbine. In the early days of our United States, we have been using the United States.
The gas turbine developed is also unreliable. It has been operating for many years before it has stabilized. Hey, can you not show this unstable engine to us?"
"What do they show if they don't show this? Their French technology is at this level, everyone has seen it?" Thomas was also fanning the flames there.
"Quick, check it out, what's the problem." Pierre ignored the provocation here and originally planned to use their engine to slap the other person in the face, but the engine was not strong and he was slapped in the face. Pierre's forehead
, sweat can't help but seep out.
There must be no problem, hurry up and see what happened?
“The oil circuit is blocked.”
These technicians, who deserve to be elites, soon discovered the problem.
"The filter is blocked."
"Replace the spare filter element."
"But we didn't bring it."
"Then remove the filter element!"
At this time, the onlookers were watching the fun. The French claimed that their engines were the most advanced. What was the result? The diesel engine had not started yet. The turbine just turned off after it started.
Miniaturized turbines are not that easy. Only aviation powers can play with them. What about the French? Their aviation technology is obviously not very good. Their most proud Phantom 2000 is called the third generation aircraft.
It’s also the only single-rotor engine among the third generation!
Thinking of this, you can also know how unbearable this engine is. If you don’t have a diamond, don’t take care of porcelain work.
