The invention relates to a method for operating a power plant (1) of a motor vehicle having a power unit (2) which generates exhaust gas, in which a predetermined value (4) of a fresh gas quantity supplied to the power unit (2) is determined at least temporarily from an operating point which is predetermined by means of an operating element (3), a target value (5) of the fresh gas quantity determined by a preset value (4) is set at the power unit (2), and at least one exhaust gas supply device of the power plant (1) is diagnosed during a diagnosis period (12). According to the invention, the target value (5) is determined from the preset value (4) during the diagnosis period (12) while filtering by means of a low-pass filter (8, 9). The invention also relates to a power plant (1).
本发明涉及一种用于运行机动车辆的动力设备(1)的方法,该动力设备具有产生排气的动力单元(2),其中,至少暂时地由借助操作元件(3)预先给定的工况点来确定供送至动力单元(2)的新鲜气体量的预设值(4),在动力单元(2)处设定由预设值(4)确定的新鲜气体量的目标值(5),在诊断时段(12)期间对动力设备(1)的至少一个排气输送装置进行诊断。在此提出,在诊断时段(12)期间在借助低通滤波器(8、9)滤波的情况下由预设值(4)来确定目标值(5)。本发明还涉及一种动力设备(1)。
