Fuel injection quantity adjusting control system

The invention discloses a fuel injection quantity regulation control system, which belongs to the technical field of fuel injection quantity regulation, and comprises a signal transmission joint end, a fuel injection lag monitoring module, a lag output variable control module and a supply control signal execution group, the oil injection lag monitoring module and the lag output variable control module are both arranged on the outer side of the output end of the pump body. The number of the supply control signal execution sets is multiple. The hysteresis output variable control module sends a debugging command to the inner cavity pressurization output end corresponding to the inner cavity oil liquid hysteresis generation position, the diameter of an oil outlet channel of the inner cavity oil liquid hysteresis generation position is changed, then the spraying pressure of oil liquid passing through the hysteresis generation position is controlled, the oil liquid fluid viscous resistance of the hysteresis generat
