ABSTRACT:
To enable the inclination of the injection direction and the distribution of the penetration force of spray to be adjusted over a wide range, and an axially symmetrical spray shape to be obtained even when the injection hole is inclined, or the shape of the spray to be changed without inclining the injection hole, a fuel passageway203is provided as a swirling force adjustment means between the valve seat201and injection hole101of the fuel injector. This swirling force adjustment means adjusts the distribution of the swirling force of the fuel flowing into injection hole101, and thus adjusts the spray shape obtained as a result.
