ABSTRACT:
An injection valve for preparing fuel injected into an intake tube of an internal combustion engine and an injection valve for performing the method are proposed. The injection valve includes a movable valve element, which cooperates with a fixed valve seat, downstream of which the fuel reaches fuel guide bores inclined relative to the valve axis and this fuel discharges into a preparation bore at a distance (a) on the bottom from the wall. The fuel flowing via the fuel guide bores at first exits freely from the discharge openings of the fuel guide bores into the preparation bore and subsequently arrives at the wall of the preparation bore, from where it flows in the form of a film, distributed over the wall, toward the open end of the preparation bore and is ejected into the aspirated air of the internal combustion engine.
