Method of operating fuel pump, involves regulating speed of fuel pump depending on fuel requirements of internal combustion engine, where speed of fuel pump is measured in time period

摘要

The method involves regulating the speed of the fuel pump depending on the fuel requirements of the internal combustion engine. The speed of the fuel pump is measured. The speed of the fuel pump is measured in a time period and is examined for speed irregularities. The speed of the fuel pump is increased during occurrence of the speed irregularities. The examining of speed for speed irregularities takes place by Fourier transformation, particularly fast Fourier transformation.
