Fuel injection valve for internal combustion engine

摘要

The valve fuel injection adjusting plate (1) has first nozzle holes (H10) arranges in a circle coaxial to the mid axis (L0) of the valve body. A second circle of nozzle holes (H3) are arranged in a second outer, circle also coaxial to the mid axis. Each hole axis of the second set of nozzles forms an acute angle with a reference surface (SB) which is orthogonal to the mid axis. The angle (a3) is smaller than the angle (a10) of the inner circle of nozzle holes to the surface. Fuel is ejected from the first nozzle holes away from the fuel injection discharged from the second nozzle hole set. Hence the fuel jets from the two groups of nozzles do not interfere with each other.
