A method of controlling torque changes in a direct injection diesel engine having a control unit which controls the amount of fuel in the engine combustion chambers depending on signals fed into the control unit representing at least accelerator pedal position and engine speed. When the accelerator pedal is depressed, for example, thereby requesting a torque (tq), which exceeds a predetermined upper torque limit (b) stored in the control unit, the torque is first controlled up to a lower torque limit (c) stored in the control unit and from there gradually to the upper torque limit (b), from which the torque is then released up to the torque requested by the driver with the accelerator pedal.
