Fuel injection valve and fuel injection system

摘要

The invention relates to an internal combustion engine, an amount of spray attaching onto an inner wall surface of an intake pipe (106) is reduced by forming two-directional spray of highly atomized fuel. The highly atomized two-directional spray (100a) can be obtained by a spray forming means which is constructed by piling a fuel in-plate (13) forming fuel passages, a swirl plate (14) forming fuel passage for adding swirl forces to the fuel, and an injection plate (15) for determining injection directions of the fuel. Further, penetrations of the sprays (100a) injected toward two directions are made different from each other. <IMAGE>
