    • Disclosed is an internal combustion engine comprising a fuel delivering device with a high-pressure pump which conveys fuel into a fuel reservoir, and a volume flow control valve that is assigned to the high-pressure pump. A control difference (FUP_DIF) is determined from a difference between a predefined fuel pressure (FUP_SP) and a detected fuel pressure (FUP_AV). The control difference (FUP_DIF) is fed to a controller that encompasses at least one integral portion (I_CTRL). A corrective value (COR) for an error value of a fuel flow rate is determined in accordance with the integral portion (I_CTRL) of the controller if a sum of the integral portion (I_CTRL) exceeds a given threshold value during a predefined mode of operation of the internal combustion engine. In addition, an actuating signal (PWM) for the volume flow control valve is generated according to a controller value (FUEL_MASS_FB_CTRL) and the corrective value (COR).
    • 公开了一种内燃机,其包括具有将燃料输送到燃料容器中的高压泵的燃料输送装置和分配给高压泵的体积流量控制阀。 根据预定燃料压力(FUP_SP)和检测到的燃料压力(FUP_AV)之间的差确定控制差(FUP_DIF)。 控制差(FUP_DIF)被馈送到包含至少一个积分部分(I_CTRL)的控制器。 如果在预定的操作模式期间积分部分(I_CTRL)的总和超过给定的阈值,则根据控制器的积分部分(I_CTRL)来确定用于燃料流量的误差值的校正值(COR) 的内燃机。 此外,根据控制器值(FUEL_MASS_FB_CTRL)和校正值(COR)产生用于体积流量控制阀的致动信号(PWM)。
