Everyone burst into applause, the Panther diesel engine, the first time it was running, 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, check the sections." Uriva shouted.

In fact, if it is in the army, after starting, it is not uncommon for the driver to step on the accelerator to the end, in the army, the equipment is used to build, and it must also be durable, for example, when fighting, it may be necessary to start the car immediately, if you don't drive, the next second the shell will fly over.

But now it's a test run, which must be safe, so now in front of the big guys, this engine is still in the state of idle 800 revolutions per minute, in this state, the Panther engine is running smoothly, and the light sound of the high-pressure oil pump is even more crisp and pleasant.

The turbocharger is almost not involved much at this speed, which is also the biggest difference between the turbocharged engine and the supercharger, at low speeds, the pressure of the exhaust is not high enough, so the supercharger cannot blow.

If you want to improve the 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, the engines of many cars were tuned in this way, so that they could output power earlier, but at the same time, because it was a small turbo, it wanted to continue to increase power after reaching the high speed range, so it was powerless.

Small turbine, the engine burst of power early, at the same time the attenuation of power will also be early, for the car, this tuning is beneficial, because many drivers drive the car to scrap, are reluctant to step on the accelerator, eager to idle the drive, and then scold the broken car is boring.

However, the tank engine is absolutely not suitable, on the one hand, the tanker has long been accustomed to stepping on the full throttle and giving full play to the maximum power of the engine, and if he wants to drive the tank by idling, it is not a matter of cursing the engine meat, but he simply cannot drive the tank.

Therefore, when idling, that is when parking, at this time, the turbocharged engine, but has an advantage, turbocharging does not intervene, that is a self-priming engine, at this time, the power of the engine is only two or three hundred horsepower, at the same time, the turbo does not intervene, the engine fuel injection will not increase, this time, just to reduce fuel consumption, usually when parking standby, the lower the fuel consumption, the better.

This advantage is also unique to piston engines, if the gas turbines used by the Americans are at low speed and high speed, and there is no difference in fuel consumption, they may consume all the precious fuel when they park.

The engine continued to run smoothly, and all kinds of data were normal, and then, Uruihua continued to give the order: "Raise to 1,000 rpm!" ”

The revs increase, the turbocharger starts to intervene, the whoosh sounds, and the power comes with it, and if the power output is drawn in a curve, it is now in a period of rapid climbing.

"Increase to 1,200 revolutions!"

"Fourteen hundred turns!"

When it reaches 1,600 rpm, the turbine has already begun to whistle like a whistle, and the exhaust gas from the 12 cylinders is blowing the turbine blades to tell the rotation, and the speed has reached tens of thousands of rpm! A steady stream of air is blown into the cylinder, fuel is injected into it, and in the cylinder, there is a violent combustion again and again, and the exhaust gas is getting hotter and hotter.

"It's already 800 horsepower!" Someone shouted happily.

So far, the largest engine in China, that is, developed by the Coal Province Diesel Engine Factory, can only output 730 horsepower, and now, our own engine has surpassed the Coal Province Diesel Engine Factory!

"Raise to 1,800 revolutions!"

The speed continued to increase, the power was still soaring, and at this time, there was already a special smell in the air, as if something had been burned.

That's the result of the turbocharger's casing being scorched at high temperatures!

The rev is up to 2,000 rpm!

The engine continued to run smoothly, and when it reached 2,000 rpm, you could see that the entire turbocharger had turned red, as if it had been taken out of a steelmaking furnace, which was quite scary.

This will not happen to the supercharger, which is driven by the crankshaft, and now, the exhaust gas turbocharging is driven by the exhaust gas discharged by the engine to push the turbine blades, and with the increase of speed, the exhaust gas discharged from the engine will be higher and higher, in fact, it is the same as the exhaust pipe of many engines is burned red.

The exhaust pipe of the engine, not a single one that does not rust, is because in the course of work, it is constantly burned red, then cooled, and constantly goes back and forth through this process.

"A thousand horsepower! The power has been boosted to a thousand horsepower, and we succeeded! Wang Erzhu looked at the display on the test bench and shouted loudly: "We succeeded!" ”

It worked!

At this moment, the entire test workshop was boiling, countless people were cheering, and some people's eyes were moist.

A machine factory has completed a pioneering feat, and for the first time in China, the power of the tank engine has been advanced to 1,000 horsepower! For the sake of this engine, they worked day and night, they overcame obstacles, I don't know how many difficulties they overcome, I don't know how many failures they have experienced.

For the first test, they were confident because they had already made a lot of preparations!

Now, the turbocharger has been burned red, and it is still working steadily, looking at this scene, Mia also sighed and said: "We are really bold! ”

"In order to achieve higher motivation, you have to try." Qin Zhenhua said: "We use aviation materials, which should be able to withstand it. ”

If you want to make the turbocharger play more performance, you can make it as close to the exhaust pipe as possible, so the turbocharger of this engine is specially designed to shorten the length of the exhaust manifold and be very close to the cylinder of the engine, so it is normal for the exhaust gas to be discharged to burn red.

It's no wonder that they can output 1,000 horsepower at 2,000 rpm, which is not an ordinary road, and the efficiency of this turbocharger is not high.

At this time, the speed of the turbocharger has also been increased to more than 20,000 revolutions, and the whistle-like howl echoes throughout the workshop.

The bearings of the turbocharger are receiving forced lubrication, and the specially designed intercooler cools the intake air, and the whole device is running smoothly.

In the midst of that shrill howling, a new era has arrived!
