A low temperature thermodynamic cycle is an inefficient one.
—”A low-temperature thermodynamic cycle is an inefficient one.”
True for the ones I’m familiar with.
Years back, some were experimenting with running gasoline IC engines at extreme temps, insulating the block to retain heat. Massive power increase for a short duration.
Guessing, with this process, less fuel economy but near-zero pollution?
Also if they running how I suspect it is still relatively warm at 500 C, combustion temp, not block.
