  • Electromagnetic fuel injection valve for in-cylinder injection
    Patent number: 10344727
    Abstract: In an electromagnetic fuel injection valve for in-cylinder injection, a fuel injection hole is an elongated hole having a major axis and a minor axis, the major axis being curved into an arc shape having a radius that is smaller than a radius of a pitch circle of an inlet of the fuel injection hole. Accordingly, the electromagnetic fuel injection valve can ensure a required flow rate even when a penetrating power is decreased.
