摘要

The fuel injection valve (10) for a motor vehicle internal combustion engine has a nozzle (30) with a valve seat (23) connected to a fuel delivery passage (26). The nozzle has an inner peripheral outlet (31) and an outer peripheral outlet (32). The valve element (24) has a seating section (25) connected to the fuel passage when the seating is raised from the valve seat. The inner peripheral outlet has an inner spacing (Di) from the valve element smaller than the outer spacing of the outer peripheral outlet.
