Abstract:
1. A fuel injection valve for an engine, comprising a nozzle body having a plurality of nozzle holes and a needle valve reciprocated in said nozzle body for controlling the inflow of the fuel into the nozzle holes, wherein the fuel is rendered to flow into each of said nozzle holes from a direction along the inner wall surface of the nozzle body around said nozzle hole in a first inflow mode, while the fuel is rendered to flow into each of said nozzle holes from a direction substantially perpendicular to the inner wall surface of the nozzle body around said nozzle hole rather than from a direction along the inner wall surface of the nozzle body around said nozzle hole in a second inflow mode, the inflow mode can be selectively switched between said first and second inflow modes, and wherein the fuel is rendered to flow into the nozzle holes in the first inflow mode before the lapse of a predetermined time after starting the internal combustion engine, and the fuel is rendered to flow into said nozzle holes in selected one of said first inflow mode and said second inflow mode as required after the lapse of said predetermined time.
