The MYT (Mighty Yet Tiny) engine technology is not entirely new, but the serious interest has only begun as of late (about 2004). The engine is claimed to have a power to weight ratio of 20:1 and some versions 40:1, that is quite something.
However, I raise an eyebrow to the claim that it is an "eco" engine, despite that it can be run on various fuels, from gas to vegetable oil. The simple fact that is has a combustion ratio of 16:1 or 32:1 per revolution, compared to a normal 4-cyl, 4-stroke engine that has a 1:1 ratio, means that it will burn 16x or 32x the amount of fuel per revolution of the crankshaft. In thermodynamics more power=more fuel, how efficiently that fuel is used is evident in that it produces more power and torque per litre, but it still only turns the crank once using 16x or 32x the fuel?
Anyone want to offer another view?
