    摘要： A heating time period is decreased by that a valve body including a hollow valve shaft is arranged in a slidable manner in a cylindrical part of a casing on which a nozzle body with a valve seat is mounted at a front end thereof, a fuel is introduced from a fuel outlet port opening on a shaft wall of the valve shaft into a fuel path formed by the valve shaft and the cylindrical part, the fuel is heated to be injected from the nozzle body by a heater arranged at an outside of the fuel path of the cylindrical part, and a sleeve is mounted in the fuel path so that a large diameter part thereof closes the fuel path at an upper area of the fuel outlet port, while a fuel inlet port is formed on a small diameter part of the sleeve to introduce the fuel into the fuel path, so that the fuel path is narrowed to decrease an amount of the fuel to be heated by the heater.

    摘要： A fuel injector has a swirl generator located downstream from a valve seat. A fuel injection hole is connected to a downstream side of the swirl generator. The swirl generator includes a swirl chamber having an involute or a spiral shape and the fuel injection hole bored at a bottom or the swirl chamber and a swirl generation use passage connected to the upstream side of the swirl chamber for introducing fuel into the swirl chamber. The bottom of the swirl chamber is provided with a step height so as to make a level difference in which the bottom of the swirl chamber is lower than a bottom of the swirl generation use passage, and the step height is formed at a position where fuel flowing into the swirl chamber from the swirl generation use passage meets fuel turning in the swirl chamber.
