FIELD: machine building.
SUBSTANCE: invention relates to a fuel feed system and a method of controlling low- and high-pressure fuel pumps in a fuel feed system. Disclosed is method of controlling engine fuel supply system. This method includes supply of voltage above threshold value to booster pump, determination of volume capacity of direct injection pump, when pressure of low pressure fuel pump exceeds threshold value, and control of booster pump considering volume capacity of direct injection pump.
EFFECT: technical result is reduced probability of inaccurate measurement of pump efficiency and higher efficiency of fuel supply system.
