Luftdichte-Änderung durch LLK: wie groß?? | Posts 16+

Hello,

The reasons for choosing intercooling versus increasing boost pressure, in my opinion, are in the following order:

Higher Carnot efficiency achieved by cooling the air before combustion. The pressure increase due to combustion is higher. (This is likely why jet turbines operate so efficiently at -50 Celsius at an altitude of 10km.)

Lower compressor capacity (pressure * flow rate).

This results in reduced thermal stress on the engine and turbocharger components with intercooling.

Best regards,
Christian.

Hi,
1. They have no other choice; it's just that cold up there.
2. The air is also much thinner.
3. Who says they actually work efficiently? The movement up there is efficient because the air is so thin, and therefore the air resistance is correspondingly low.

Everything else is probably more a matter of perspective...

Greetings.

Eike.
