Abstract
A fuel injection nozzle is configured and dimensional with a flat flow passage just above the outlet orifice(s). When the abutting portion of a needle valve moves away from the valve seat, fuel flows are directed uniformly toward the orifice from around its periphery so as to collide with each other just above each orifice inlet. Atomized fuel is then injected to the engine from the orifice. The internal energy of the fuel flows can more effectively be utilized in the collisions to more finely atomize the fuel and to maintain the ability to provide a highly direction output injection spray.
