Sind 0,4 Bar Ladedruck viel?
Hi,
ich fahre einen Corsa E 1.4T mit 101PS und 200NM. Wenn man mehr Gas gibt haut der Turbolader 0,4 Bar Ladedruck in die Brennkammern. Sind 0,4 Bar eigentlich viel für so einen 1.4 Motor? Der Lader ist ja eigentlich nur dafür da, um im niedeigen Drehzahlbereich die 200NM zu bringen, was beim Sauger mit 101PS natürlich nicht möglich ist.
Meinen Motor kann man doch mit den 0,4 Bar nicht überstrapazieren oder? Klar, bei Leistungsstärkeren Autos haut der Lader gut und gerne 1,5 Bar rein, was ja glaub ich schon ne Menge ist. Kenne mich mit Ladedrücken jezt nicht soooo dolle aus.
Kann man sagen je mehr Druck je mehr wird der Motor belastet und sind meine 0,4 Bar dann Peanuts? Auch beim warm fahren z.B. soll man ja achten, dass man die ersten paar Kilometer den Turbo nicht zu viel fordert.
Was meint ihr? 🙂

No, that’s a lower value. A standard turbo goes up to about 0.8 bar. After that, some effort is necessary and not good for the longevity of a motor.
0.4Bar is more a pressure to make the motor more durable.
With 0.4 bar you can also operate a series engine without problems with a turbocharger. With over 0.8 bar, the engine must be designed for a turbo. Then some reinforced parts are installed and the cooling must fit. The pistons and connecting rods are very stressed.
All right, thanks. Does it mean that it’s not harmful, but that if I slip on the gas at lower speeds? Max. Torque is applied from 1850 revolutions.
A turbo doesn’t like it when you pull it up with a cold engine. Turbos spin with over 100000 tours. It is important that the bearings are always well lubricated. Cold oil has a higher viscosity and therefore cannot melt well at all points. In addition, a turbo must not be blown up shortly before the engine is switched off. The blades need something to get to the stand from the high speed. Without a motor, however, the oil supply breaks off. This can damage a turbo.
In the case of a warm engine, a hose from the stand is not harmful.
That’s what we’re here for. To create more power.
Sorry, again replied:D
I know. I’ll always ask the engine when it’s warm. Before leaving, I have to open the garage and roll it in again 45 seconds:)
You’re on the right track.
No, that’s very moderate. Even a liter capacity of 72 hp is not exaggerated. You don’t have to build up the most expensive materials in the engine, which then of course costs.
Right, which contributes especially in urban transport to the charitable saving.
No, valves and bearings should last long.
That’s right. For example, the Audi 2.5 TSFI has a charging pressure of 1.5 bar (400 hp) and the AMG 2.0 liter turbo (M139) even has 2.1 bar charging pressure and brings over 420 hp. Take a look at what they cost.
Yeah, you can say that.
Right.
Thank you. Then I think correctly:D
No, he’s important in the complete power range so that the engine gets enough air. 0.4bar charging pressure means that you have 40% more air in the engine, so also 40% more oxygen, which means that you can burn about 40% more fuel per ignition.
The load is, of course, higher because more fuel is injected and thus also more combustion pressure is produced, but the engine is designed for this purpose
Thank you 🙂 Good explanation
Nö… quite normal charge pressure to keep the motor durable…
Then good 🙂
Fully correct charging pressure. 👍 Come to Spain!
Then good 😀
