I scanned quickly the paper posted, It seems that lower NOx emission is a key point. However, the turbine engine and the reciporcating engine mentioned in the new generation innovation are heat engines.
I welcome the use of new catalytic processes and such innovation, but I fail to understand how low temperature combustion leads to greater thermodynamic efficiency.
I get that gas bearings are better than sliding bearings, and so on, but again where is the magic? I hope that this is a disruptive technology, but I am not seeing it yet.
Best Regards.
It doesn't. See Carnot. The greater the temp differential, the higher the thermal efficiency.
Unless "efficiency" is relative to the best theoretical efficiency under a given temperature differential. Even then, it's easier to get high efficiency with high temperature.
This technology is sold as low emissions.
This isn't disruptive technology on the prime mover side. Maybe some on the power generating side, with the linear magnet the voltage woul dhave the same periodic regularity inherent to rotating machinery.
