The invention discloses an electronic speed regulator on the basis of single chip microcomputer control for diesel engines. The electronic speed regulator comprises a cam shaft, a rotational speed sensor, a lever mechanism, a case of a diesel pump, a toothed rod of the diesel pump, a displacement sensor, a diesel cut-off control rod, a threaded transmission mechanism, a stepper motor and a driving screw. The cam shaft is connected with the rotational speed sensor, the toothed rod of the diesel pump is connected with the displacement sensor, the lever mechanism is connected with the toothed rod of the diesel pump, and the stepper motor is connected with the lever mechanism by the driving screw and the threaded transmission mechanism. The electronic speed regulator has the advantages that the stepper motor can drive a rack of the diesel injection pump to move under the control of a single chip microcomputer, so that the diesel injection quantities can be regulated, and the rotational speeds of the diesel engines can be controlled; the diesel supply quantities can be automatically regulated according to change of different loads by the aid of control algorithms and a hardware structure with the single chip microcomputer as a core, and the position of the toothed rod of the diesel pump is reasonably controlled, so that the electronic speed regulator has properties of low idling diesel quantities, low diesel supply quantity fluctuation and fast over-speed supply cut-off and is low in cost and simple in structure.
