    ) scope of the bent axle of upper dead center, be generally lower dead centre before this afterwards between 120 °

    -150 °

    , this moment, piston advanced 90% along this direction or upper dead center direction, for example from 10% to this, as shown in Figure 4 and Figure 5, gas exchange is just finished in the piston arrives before top dead center like this, is compression for the second time afterwards, mixture spontaneous combustion or lighted and expand.
