摘要： Using a swirl type fuel injection valve, a concentrated spray area and a thin spray area are formed, the positions thereof are adjusted, and the spray is made to conform to the geometric shape of the engine and mounting position of the fuel injection valve, so as to reduce the fuel consumption and control the unburnt components in exhaust gas. The fuel injection valve is so constructed that a step is formed on the injection hole opening of the fuel injection valve, so as to provide two or more edge transition portions at the injection hole opening, resulting from the step, and the line connecting the edge transition portions forms an oblique angle relative to the wall formed by the step perpendicular to the injection hole center axis and the angled wall.

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： When voltage changes occur in the battery used as a power supply in a fuel injection system, the amount of fuel injection also changes and the required amount of fuel injected cannot be obtained. To eliminate this problem, a fuel injector system is provided which has a fuel injection valve with at least one coil, a power supply, a power supply voltage detector, and a control unit for controlling the fuel injection valve. The control unit sets a reference value of a power supply voltages, and the above-mentioned fuel injection valve is controlled so as to obtain the required ampere-turns by reducing the resultant inductance of the coil when a power supply voltage detection value is less than the above-mentioned reference value, and the resultant inductance of the coil is increased when the power voltage detection value is greater than the reference value.
