ICE Thermodynamics @.Thermal barrier gold plating
(OP)
Hi Eng-Tips,I'm a retired Marine Engineer who's back to back dyno Eng test experiment showed heat loss reduction >20% and 6.8% Hp increase via 24K gold plated combustion space surfaces, B&S Intek Si Eng.
The question is efficiency improvement,is this quantifiably attributed to increased Entropy, Exergy, or both.
Does this imply a new Heat Transfer Model required,that describes improved ICE efficiency limit.
Regards and thanks.

RE: ICE Thermodynamics @.Thermal barrier gold plating
I think you have two back-to-back dynometers, but are you testing the difference from the one with a goldplate chamber and the one without?

RE: ICE Thermodynamics @.Thermal barrier gold plating
Well, assuming your numbers are correct you have increased exergy (work done by the system), so entropy (losses) must have correspondingly been reduced.
RE: ICE Thermodynamics @.Thermal barrier gold plating
SO, to improve efficiency you'd need to reduce thermal losses, reduce friction and inertia between all of the moving parts, increase the peak pressure and peak temperature of the hot gasses, reduce the outlet pressure and temperature, or some measure of all of the above.
