Method for filling the fuel supply system in an internal combustion engine
First Claim
1. A method for filling the fuel supply system in an internal combustion engine, with a fuel pump which is operated by means of a control device, and with means for detecting operating states of the internal combustion engine, which means emit corresponding output signals, in particular relating to the position of the throttle valves, the ignition switch or the rotational speed, wherein, when the fuel pump is activated, a differentiation is made between a normal start and filling of the fuel supply system and the differentiation is carried out by the control device as a function of detected operating states.

Abstract
A description is given of a method for filling the fuel supply system in an internal combustion engine, in which the fuel pump is activated by the control unit. If the control unit recognizes, as a function of measured variables, that filling with fuel should take place, it activates the fuel pump in a manner such that a sufficient filling of fuel is already obtained before the internal combustion engine starts. If, on the other hand, the control unit recognizes a normal start, the customary method for controlling the electric fuel pump is executed. The time control of the electric fuel pump is changed over to normal activation also as a function of recognized termination conditions.
