摘要： A method for operating a quantity-controlled internal combustion engine having at least two cylinders, including the following steps: ascertaining a present operating state; determining a number of cylinders or cylinder groups to be deactivated in dependence on the present operating state; deactivating or keeping deactivated a fuel supply for at least one cylinder to be deactivated or at least one cylinder group if at least one cylinder or at least one cylinder group is to be deactivated; and opening a flow-influencing element associated with the at least one cylinder or the at least one cylinder group for a fresh mass supply to the at least one cylinder to be deactivated or the at least one cylinder group to be deactivated.
摘要翻译： 一种用于操作具有至少两个气缸的数量控制的内燃机的方法，包括以下步骤：确定当前操作状态; 根据当前操作状态确定要停用的气缸数量或气缸组数; 如果要停用至少一个汽缸或至少一个气缸组，则停用或保持停用用于要停用的至少一个气缸的燃料供应或至少一个汽缸组; 以及打开与所述至少一个气缸或所述至少一个气缸组相关联的流量影响元件，用于新鲜质量供应至待停用的所述至少一个汽缸或所述至少一个气缸组被停用。

摘要： A method for monitoring a cylinder pressure sensor, in which method the sensor value is checked for admissibility and inadmissibility in a predefinable crankshaft angle range, when admissibility is detected the cylinder pressure sensor is used further and when inadmissibility is detected the cylinder pressure sensor is deactivated. A first sensor value of the cylinder pressure sensor is set as a start value, and a second sensor value is set as a stop value, a plateau range is determined from the number of sampling steps between the start value and the stop value, and the plateau range is set as decisive for the admissibility or inadmissibility of the sensor values.
