1. split-cycle air mixing power engine comprises:

  • Bent axle can be around the crankshaft center line rotation;

    Compression piston is slidably received within the compression cylinder, and is operably connected to bent axle, so that aspirating stroke during the single rotation of compression piston through bent axle and compression stroke and to-and-fro motion;

    Expansion piston is slidably received within the expansion cylinder, and is operably connected to bent axle, so that expansion stroke during the single rotation of expansion piston through bent axle and exhaust stroke and to-and-fro motion;

    The changing channel interconnects compression cylinder and expansion cylinder, and this changing channel comprises exchange compression (XovrC) valve and exchange expansion (XovrE) valve, between said exchange compression (XovrC) valve and exchange expansion (XovrE) valve, is limited with the pressure chamber;

    Air reservoir is operably connected to the changing channel, and can optionally operate to store from the pressurized air of compression cylinder and transmission pressurized air to expansion cylinder;

    WithThe air reservoir valve, optionally control air flows to and flows out air reservoir;

    Motor can turn round in air expansion and igniting (AEF) pattern, and wherein, in the AEF pattern, motor had 15.7;

    1 when the XovrE valve cuts out or bigger residue expansion ratio.
