How does Rotary work???

  1. Could you guys inform me on how the rotary engine works?
    Thanx!<!-- Signature -->

    Re: How does Rotary work???

    Instead of having a piston that moves up and down, like in a normal engine, a rotary has triangular rotors that spin around.

    See the following URL for a way better explanation, as it's sort of hard to explain: <!-- Signature -->

    Yeah, hence the power from such a small displacement. Basicly, unlinke conventional motors, the rotary does not have to directly work to move the piston when it is not in its power stroke. The inertia of the spin does that. A regular motor has to work directly to move the pistons when they are not in their powerstroke.<!-- Signature -->

    yeah, and because of the inertia of the spining motion, the rotary spins 3 times in the time it takes to spin a regular piston engine to make a complete cycle because it doesn't have to force itself to move once you get it started

    A rotary has 3 stages.
    Intake: Rotor spins 1/3 the way. Air from the intake is sucked into the chamber and prepared for combustion.

    Combustion: Feul is injected by feul injectors and the rotor spins 2/3 around. By compressing the air and burning the feul, power is created.

    Release: The exhaust is released out of the exhaust manifold. The rotor has made a complete rotation.

    They sound great too, for a non V8 anyway
  8. Re: How does Rotary work???

    Plus they have much less moving parts than traditional combustion engines.<!-- Signature -->

    Actually, the rotary is still a 4-stroke motor. It has the same intake, compression, expansion and exhaust phases as their piston counterparts. But, yeah.... 2 (3 or 4 in some cases) triangles that spin round and round and go Hmmmmm....... <IMG SRC="">
