The method enables the dynamic running characteristics of diesel engines to be adjusted by use of a simulator via an electronic speed governor R for controlling the fuel pump injection. The method allows simulation of the number of cylinders and number of strokes of the diesel engine under adjustment, and variation of the torque curve of individual cylinders. It is also possible to test the running of the diesel engine and its governor (R) under load changes of the most diverse kinds, such as load reduction or complete or partial failure of a cylinder. The simulator includes blocks for generating signals corresponding to an injection pump setting, for simulating the torque curve or curves of the engine cylinders and integrating the generated torque signals including on-load torque and disturbance signals to form a speed signal. A voltage/frequency convertor converts the speed signal to a frequency signal for output to the electronic governor.
