Car Tuning: Online & Thermoelectric Power Generation

Hi,

I just received a newsletter with interesting content.

'Firstly, a USB-connected EEPROM emulator is offered, which could be interesting for online tuning. Secondly, it concerns thermoelectric energy generation, which could potentially be used in cars in the future.'
But see for yourselves, or rather, read for yourselves:

Greetings.

Hello,

The use of emulators is absolutely not permitted. Following several accidents, this has...
To the best of my knowledge, the KBA (German Federal Motor Transport Authority) has even prohibited vehicle testing on public roads for vehicle manufacturers.
In the event of an accident, it will most likely be the worst-case scenario from an insurance perspective.

Regarding the conversion of temperature differences into mechanical power, developers of diesel and gasoline engines have been desperately trying for over a hundred years to achieve an efficiency of around 40% for automobiles. Achieving 18% with new thermoelectric elements is still not a breakthrough.

Best regards,
Christian.

Hello,

The comparison is a bit flawed because those 18% are in addition to the energy, and they might potentially replace the LiMa (lithium-ion batteries). You can consider these 18% as a step towards increasing your overall efficiency of 40%.

Why not simply use a small Stirling engine to convert the temperature difference into work?

The 18% figure mentioned in the article only applies to a temperature difference (Delta T) of 600K. Where else do our TDI engines produce such high values, other than directly at the turbocharger inlet (where they are actually needed)?
Who knows what temperature the exhaust gases are after they have done work on the drive wheel from the turbocharger?
(And who quickly calculates the additional work gained, considering the exhaust gas flow rate of xxx, the temperature difference of yyy, and the efficiency of the Stirling engine?)


Best regards, Georg.
