Abstract
A fuel injection valve, for an engine, comprising a nozzle body having a plurality of nozzle holes and a needle valve reciprocated in the nozzle body for controlling the inflow of the fuel into the nozzle holes is disclosed. The fuel is rendered to flow into the nozzle holes from a direction along the inner wall surface of the nozzle body around each of the nozzle holes in a first inflow mode, and from a direction substantially perpendicular to the inner wall surface of the nozzle body in a second inflow mode. The first inflow mode and the second inflow mode can be selectively switched to each other. The fuel is rendered to flow into the nozzle holes in the first inflow mode before the lapse of a predetermined time after the engine is started, and in the first or second mode as required after the lapse of the predetermined time.
