Abstract:
A fuel injection valve of an internal combustion engine includes a measuring plate that has at least one injection hole. Fuel that has flowed along an inner wall surface of the measuring plate flows into the injection hole through an injection hole entrance that is formed in the inner wall surface of the measuring plate, passes through the injection hole, and is injected through an injection hole exit that is formed in an outer wall surface of the measuring plate. A recess is formed from an injection hole entrance rim to an injection hole exit rim in an upstream section of the inner wall surface of the injection hole in a fuel flow direction along the inner wall surface of the measuring plate.
