    • A method and a device for regulating the boost pressure of an internal combustion engine having a multiflow air system, which enables both rapid regulation and limitation of the exhaust gas back pressures. The multiflow air system includes a multichannel air supply and a corresponding multichannel exhaust gas discharge, each exhaust gas channel having an exhaust gas turbocharger. A manipulated variable for a specified boost pressure to be set is determined as a function of the actual exhaust gas back pressure prevailing in the particular exhaust gas channel, a total specified exhaust gas back pressure being determined by a first controller from the difference between the specified boost pressure and an actual boost pressure, and a specified exhaust gas back pressure being determined for the individual exhaust gas channels from the total specified exhaust gas back pressure as a function of a difference between the air mass flows supplied via the air channels of the internal combustion engine. The particular manipulated variable for the specified boost pressure to be set is determined by an additional controller from a difference between the specified exhaust gas back pressure and the actual exhaust gas back pressure of the particular exhaust gas channel.
    • 一种用于调节具有多风系统的内燃机的增压压力的方法和装置,其能够快速调节和限制排气背压。 多气流系统包括多通道空气源和相应的多通道废气排放,每个废气通道具有排气涡轮增压器。 根据特定废气通道中存在的实际废气回压确定用于要设定的指定增压压力的操纵变量,由第一控制器从指定的排气通道之间的差确定的总规定排气背压 提高压力和实际增压压力,并且对于各个废气通道,从总规定排气背压确定的特定排气背压作为通过内部空气通道供应的空气质量流之间的差异的函数 内燃机。 用于规定的增压压力的特定操纵变量由额外的控制器根据特定废气回流压力和特定废气通道的实际废气背压之间的差来确定。
