"textContent": "A method for controlling pressure in a high-pressure region of an internal combustion engine includes adjusting a fuel outflow from the high-pressure region into a low-pressure region by means of an injector, which has a control valve adjusted by a piezo actuator and a control chamber. The method includes charging the piezo actuator by a first signal such that the control valve is moved from a closed position to a partially open position and fuel flows out from the high-pressure region into the low-pressure region, discharging the piezo actuator by a second signal such that the control valve is moved into the closed position, and partially discharging the piezo actuator by a third signal after the first signal and before the second signal. The method provides pressure control in the high-pressure region via an injector with high reliability even at high rail pressure.",
