ABSTRACT:
An engine having a plurality of fuel injectors each being actuated by a piezoelectric element. The fuel injectors are connected to a common pressurized fuel accumulating chamber. A pressure sensor is arranged in the pressurized fuel accumulating chamber. A fuel feed pump is provided for feeding pressurized fuel into the pressurized fuel accumulating chamber. The amount of pressurized fuel discharged from the fuel feed pump is controlled in response to the output signal of the pressure sensor so that pressure in the pressurized fuel accumulating chamber becomes equal to a predetermined desired pressure.
