7) the flow regulation time maximum limit of upper-position unit to flow regulation time and default compares, if flow regulation time is less than maximum limit, then returns step 7) operation, proceeds flow adjustment, otherwise, then carry out next step;
8) the normal working flow minimum limit value of the flux signal that detects in real time of upper-position unit flow sensor and default compares, if the flux signal detected in real time is greater than normal working flow minimum limit value, then fuel supply flow rate control procedure terminates, otherwise, carry out next step;
9) upper-position unit instruction control unit starts alarm, and make system stalls, fuel supply flow rate control procedure terminates simultaneously.
