Abstract
The subject matter described here relates to a method, a controller and computer program product for controlling a fuel pump of a fuel supply system for an internal combustion engine, and a fuel supply system for an internal combustion engine.The problem to be solved is not being provided with an efficient fuel supply system capable of supplying various types of fuels without bubble formation under different environmental conditions.The method comprises the steps of measuring a pressure of a fuel in the fuel supply system by a first measuring means; measuring a temperature of the fuel by a second measuring means; measuring a physical parameter of the fuel by a third measuring means; determining, by a control unit, a fuel type based on the measured physical parameter of the fuel, a vapor pressure of the fuel based on the determined fuel type and the measured temperature, and a pressure amplitude of the measured pressure; calculating, by the control unit, a first target pressure value as a sum of the determined vapor pressure, the determined pressure amplitude and a predetermined pressure margin, and a pressure difference between the first target pressure value and a predetermined se…
