Abstract:
A fuel injection valve for an internal combustion engine is such that an inside wall of a nozzle hole through which fuel is injected into a combustion chamber or an intake port of the internal combustion engine is coated with a composite coating formed of a lipophilic portion and an oil repelling portion which are finely interspersed on the nano order. The inside wall of the nozzle hole is formed by multiple grooves extending in the fuel jet direction and flat portions between these grooves, and inside walls of the grooves are coated with an oil repellant coating and the flat portions are coated with a lipophilic coating.
