    摘要： With reference to FIG. 1, the present invention provides an internal combustion engine (10) comprisinga variable volume combustion chamber (13); an air intake system (18,20,21) for delivering charge air to the combustion chamber (13); an exhaust system (17) for relaying combusted gas from the combustion chamber (13) to atmosphere; anda fuel injection system (19, 21, 22, 23, 24, 25, 26) for delivering fuel into the charge air for combustion therewith in the combustion chamber (13). The fuel injection system (19,21,22,23,24,25,26) comprisesa fuel injector (19) which functions as a positive displacement pump and dispenses an amount of fuel which is fixed for each and every operation of the injector (19); and a controller (23) which controls the operation of the fuel injector (19). In response to an increasing engine speed and/or load the controller (23) increases in amount the fuel delivered per engine cycle by increasing in number the occasions the fuel injector (19) is operated per engine cycle. In response to a decreasing engine speed and/or load the controller (23) reduces in amount the fuel delivered per engine cycle by reducing in number the occasions the fuel injector (19) is operated per engine cycle.

    摘要： A fuel injector with a magnetic coil, which cooperates with an armature acted upon by a restoring spring, the armature forming an axially movable valve part together with a valve needle. A valve-closure member, which forms a sealing seat with a valve-seat member, is provided at the valve needle. An inner pole and an outer pole form a magnetic circuit with the magnetic coil. A membrane is positioned at an inflow-side end face of the inner pole, which includes at least one orifice, which is covered by the inner pole in the dosed state of the fuel injector.

    摘要： 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.
