Abstract
In order to provide a fuel injection method of an internal combustion engine having higher combustion stability which can direct a part of concentrated fuel spray toward an ignition plug according to a fuel injection atmosphere, a fuel injection valve thereof, and an internal combustion engine, the present invention provides a fuel injection method of an internal combustion engine for injecting fuel so as to generate a part of high spray concentration and a part of low spray concentration on the cross section of spray by giving swirling force to fuel from an injection hole at the front end of a fuel injection valve, comprising the step of setting a reference indicating the position of a axis of the fuel injection valve indicating the injection direction of the part of high spray concentration in the rotational direction when fuel is injected into an atmosphere under the atmospheric pressure.
