摘要： A fuel injector including a valve housing having a fuel injection hole formed at a front end of the valve housing; a valve movably provided int he valve housing so as to open and close the fuel injection hole; a nozzle fixedly mounted to a front end of the valve housing; and a fuel colliding member provided in the nozzle and positioned in alignment with the fuel injection hole in front thereof. A size of the fuel colliding member is smaller in cross section perpendicular to an axis of the fuel injector than that of the fuel injection hole. Accordingly, a radially inside part of a columnar fuel after collision with the fuel colliding member further collides with a radially outside part of the columnar fuel passing outside the fuel colliding member to accelerate atomization of the fuel without reducing a velocity of flow of the fuel.

摘要： Driving circuitry for an electromagnetic fuel injection valve in which the holding current value is made variable to obtain a minimum necessary holding force from the holding current according to the fuel pressure includes a solenoid for driving the fuel injection valve, a capacitor charged by a high-voltage charge control part, a switch circuit for on-off controlling a high-voltage current supplied from the capacitor to the solenoid in response to an injection command signal, and a holding current supply circuit for supplying a holding current from the power supply to the solenoid. When the holding current is supplied, a comparator circuit compares a voltage obtained by converting the value of electric current flowing through the solenoid by a resistor for detection and a voltage corresponding to a fuel pressure sensor signal, and the value of the holding current is varied according to an output signal from the comparator circuit.

摘要： A fuel supply system includes a pressure regulator (16) regulating the pressure of fuel supplied from a fuel pump (14). A valve device (18) is associated with the pressure regulator (16) for controlling the pressure of the fuel regulated by the pressure regulator (16). The valve device (18) supplies a part of the fuel as a control fluid to the pressure regulator (16). The part of the fuel supplied from the valve device (18) as the control fluid is not discharged into a fuel tank (12) when the pressure regulator (16) regulates the pressure of the fuel to have a higher value.
