摘要 |
The invention relates to a fuel injection valve, in particular, a fuel injection valve extending directly into a combustion chamber of an internal combustion engine, with an energisable actuator (10, 11, 12), a valve closing body (7), displaced by said actuator (10, 11, 12), a fixed valve seat (22) with which the valve closing body (7) co-operates to open and close the valve, a fuel outlet formed, in a downstream spray region, from at least one outlet opening (23), arranged downstream of the valve seat (22) and with a dead volume (25), formed upstream of the spray region with at least one outlet opening (23). The dead volume defining surface (33) of the valve closing body (7) comprises a surface structure with at least some pores for the storage of combustion chamber gas having a pore depth of at least 25 mu m. |
