Abstract
A nozzle plate has a plurality of blades in the area that surrounds the nozzle hole on the outer plane of the bottom wall part. When the fuel is injected from the nozzle hole and the pressure in the vicinity of the nozzle hole is reduced, the plurality of blades guide a flow of air from the radially outward side of the bottom wall part to the radially inward side of the bottom wall part and generates a swirling flow of the air about the center of the bottom wall part. The swirling flow of the air about the center of the bottom wall part changes to a helical flow by receiving kinetic momentum from fine particles of the fuel injected from the nozzle hole and the helical flow of the air transports the fine particles of the fuel.
