Sat, 22 October 2005 16:33 woohoo!!! the QT400 engine. 1600c swept volume per revolution (so 3.2L based on 2 revs) maximum speed 2000rpm maximum theoretical power = 56kw this equates to 266Nm compare that to todays terribly inefficient piston engines.. 3.2L typically around 300-320Nm maximum speed.. typically around 6000-7000rpm. so you could optimise a piston engine, with the same swept volume per revolution, and it will still have higher torque at low rpm, as well as being more flexible... their point is that photo-detonation is better at partial loads, but to use photodetonation, you need clean fuels (but they don't state which.. only that it is not petrol or diesel etc) so wtf are you on about with this oil war crap... the designs look a little flaky as far as being "oil-less".. wen you have friction, you have heat, and snce both designs have more side seal area than a rotary, methinks they will be generating significant heat. it's a lovely idea, but they are relying on vague and wishy washy concepts of photo-detonation to prove their point. they do not actually suggest which fuels they could use, nor talk about their self detonation pressures or tempeatures etc etc.. ie, as nice as it seems, the basic scientific backbone is fragile. unless of course... you can show the thermodynamic argument that they are more efficient....
