HA! I love your first link there. ...they go for sounding all techy and .. ."This form of combustion further achieves higher thermal efficiencies that deliver better
Break Specific Fuel Consumption (BSFC)"
Is that where an engine falls apart with less fuel?
btw, Improving turbulence in combustion chambers is nothing new. Engineers have some great tools for optimizing this mixing. ...toroidal swirl usually gives the best mixing. ...although, "Vortex" may
sound more powerful.
The thing is, so much of the time, motors are built for great BSFC . . .but they then lack flexibility. That is, they are tuned to work well in an rpm sweet-spot. Maybe if we had a great CVT, ...
anyway. so much of this has been done before. It's hard, for most, to sort out what's a scam, and what's actually useful.
Although, kudos to Porsche for their inroads into in-cylinder injection (gasoline engines) ...gain an MPG or two there.
