    MYT Engines, a new technology?

    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?

    Power is power, the fact that it burns 4 time or more fuel per revolutions, means that there is more torque per revolution, and therefor your gear box ratio would change accordingly.

    A typical engine must rev at 3,000RPM plus to achieve maximum torque, so the gearboxes are ratio-ed accordingly. I am assuming that this MYT engine peaks at 1000RPM, so the gearbox ratio would change so that you could achieve the same speed at the lower RPM, because the engine has the power to maintain the speed.

    If this is a genuine engine, the advantages are tremendous, because you now have a smaller engine compartment, and the weight of the engine is probably a third of a typical engine, making the savings even higher, because the total vehicle weight is less, and therefor requires less fuel to manouver.

    It is indeed a genuine engine, but is being researched by a privately funded organisation, I think it is "Angel Labs LLC". I agree with the gearbox reduction and differential ratios. I haven't done all the maths yet, but if I look at it from layman's view. The idle speed of the MYT is 50RPM, power band is from 150 to 550RPM, torque band is 200 to 800RPM, and max. speed 1200RPM. Compared to a standard car, Idle 800RPM, power band 2000 to 4000RPM, torque band 2500 to 5500RPM, and max speed 7000RPM. There is some serious reduction required to make it fuel efficient.

    So far, a working prototype was fitted into a standard Ford Focus, but the results weren't very promising, but then they didn't alter anything in the Focus, just popped in the motor and went for a drive, very noisy.

    PS. These are not actual figures, just numbers used to visualise. The actual figures for the MYT have not yet been released (I wonder why?)
