摘要： Using a swirl type fuel injection valve, a concentrated spray area and a thin spray area are formed, the position 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： An electromagnetic fuel injection valve in an engine injects fuel by opening/closing a fuel flowing path with a valve element. A controller controls opening/closing of the fuel flowing path and changes magnetic force generated by a control coil driving the valve element so that the magnetic force is less during a valve open state-holding period than at an initial valve-opening time. The controller detects the voltage of a battery and applies the voltage fed from the battery to the control coil, while changing a time interval (Tc), for which current is passed through the control coil, based on the detected voltage, in order to change the magnetic force, without raising the voltage from the battery. The controller also detects increase/decrease of a pressing force on the valve element caused by fuel pressure and changes the time interval (Tc) accordingly.
