Fuel injection valve for fuel injection system of mixture-compressing spark ignition internal-combustion engine, has discharge ports formed in region of channel ends of inflow channel that tapers in channel width

摘要

The valve has a valve seat body (16) with a valve seat (29) and a valve closing body (7) that cooperates with the seat, where the closing body is axially movable along a valve longitudinal axis (2). An atomizing device is arranged downstream of the seat and is designed as a multi-fan jet nozzle (23) with multiple slot-shaped discharge ports. The nozzle has an inflow channel in the direction of flow, where the channel follows the discharge ports in the direction of flow. The discharge ports are formed in a region of the channel ends of the inflow channel that tapers in channel width.
