Method for actuating fuel pump in fuel injection system of motor car, involves increasing the flow rate of fuel pump at determined period of time, and cleaning the pumped fuel with fuel filter

摘要

The method involves recognizing (50) the refueling with the fuel. The flow rate of the fuel pump is increased at the determined period of time. The pumped fuel is cleaned with a fuel filter (20). The low pressure fuel pump (22) of the common-rail device (10) is driven (54). The fuel is purified in the wake and flow. The refueling of the tank (14) by increasing article is detected. The time-controlled change in the driving of the fuel pump is performed based on the refueling amount. An independent claim is included for an arrangement for actuating fuel pump in fuel injection system of motor car.
