ABSTRACT:
A liquid fuel injection system includes an injection unit for atomizing liquid through application to the fuel vibration energy induced by the operation of piezoelectric/electrostrictive elements, and a discharge valve for discharging pressurized fuel into the injection unit. Only during a period of time when an intake valve of an internal combustion engine is closed, an electric controller supplies a drive voltage signal of a certain frequency to the piezoelectric/electrostrictive elements of the injection unit so as to operate the piezoelectric/electrostrictive elements, and a valve-opening drive signal to the discharge valve so as to discharge fuel into the injection unit from a fuel path of the discharge valve.
