Abstract
It is equipped with an injector bodywhich has formed therein high-pressure paths, andthrough which high-pressure fuel flows to a spray hole and stores therein a piezo-actuator(i.e., an opening/closing mechanism) and a back-pressure control mechanism(i.e., an opening/closing mechanism) which open or close the spray hole, and a fuel pressure sensorinstalled in the bodyto measure the pressure of the high-pressure fuel. The bodyhas formed therein a branch pathdiverging from the high-pressure pathsandto deliver the high-pressure fuel to the fuel pressure sensor
