US 2020/0049118 A1 · Fuel Injection Valve

Abstract

An object of the present invention is to provide a fuel injection valve that can be used in a gasoline engine and can take fuel into an injection hole with a small pressure loss near a seat portion on which a valve is seated. Thus, the present invention provides a fuel injection valve for a gasoline engine which includes: a plurality of injection holes; and a seat portion that opens and closes a fuel passage to the plurality of injection holes in cooperation with a valve. At least one fuel injection hole among the plurality of injection holes is configured in a shape such that an injection hole inlet has a long axis and a short axis, and the long axis is directed in a direction in which an extension line intersects with the seat portion.
