  • @comicquartz9129

    I think there are multiple ways to improve torque on the engine, so I will list some:
    1. Adding another rotary.
    2. Adding a pro/supercharger.
    3. Improving the rotor to maybe have 5 compression areas instead of the 3

    • @redshoebox
      @redshoebox  2 ปีที่แล้ว +27

      Good ideas. I think the main problem with this engine is that because the peanut shape housing isn't perfect, the air leaks into the other chambers and overall the housing is not sealed well. This is something that is hard to achieve with LEGO but I think a second rotor may help.

      @@laudo_au2418 Technically yeah, but when you’re already using pressurized air to power it, it makes no difference. It isn’t a combustion engine sucking air in. So it technically already has boost like a supercharger or turbo would provide for a IC engine. So in this case just upping the air pressure would be sufficient. However as the creator has mentioned, the housing isn’t perfect. It has too many leaks and isn’t shaped quite right.

    You added that little pipe to make an air go through it instead of compressing. But, what you didn't noticed is that the piston blocks an air from going into a pipe.

    • @redshoebox
      @redshoebox  2 ปีที่แล้ว +1

      As the rotor pushes air through the pipe, the rotor also blocks the air from moving. Since the air has nowhere to go, it has no choice but to actually push the rotor, which (in theory) would boost the engine performance. However, the boost of this is minimal since it is LEGO, and I could not achieve perfectly airtight shapes and geometry.

    Doesn’t work great because, inlet is placed wrong, there’s no outlet, the housing has a wrong shape, it’s actually more pear shaped, apex seals don’t seal, they need pressure against the wall, also there’s no way you can create the right seal using legos against the side walls.
