Militant EV driver!
They say how efficient it is in the videoIt'll be interesting to know how efficient it is... Personally I like the idea of having a Jet engine in my car ala 'TREV'...
I've not had chance to watch it yet (I'm at 'work'), I recall the TREV being around 40%? If it's efficient it shouldn't be noisy as such. I expect there will be less vibration than any reciprocating engine. I'll certainly be following both technologies with interest.They say how efficient it is in the video
30% more efficient than an ICE, they say around 50% efficiency.
Hmm, their pressure-volume diagram is v suspicious! Seems to claim expansion to V large volume to allow pressure in cylinder to decrease to atmospheric. This won't work, for obvious reasons. Secondly, they claim that conventional rotary ICE using conventional Genny is bad, and their linear arrangement is better as goes straight to leccy avoiding crankshaft & eccentric. Sadly, 100 % of their motion energy has to go to Genny, then to leccy motor & back to motion, losing some efficiency every conversion. Ampera can feed the ICE motion straight into the wheels via single gear (maybe two) reduction, and is more efficient. Their linear Conrods also give zero flywheel effect, so expect a jerky motion .vs. rotary Genny acting as V useful smoothing flywheel. So I do not expect to see this being a winner.Free piston engines are now being developed specifically for PHEVs and offers true integration between the ICE component and the electrical components. I love this design...
