摘要: A method for operating an internal combustion engine, in which an erroneous lift of an intake valve of a cylinder is directly determined. The lift of an intake valve of at least one cylinder of the internal combustion engine is diagnosed. A value for a specific cylinder which is representative of the air/fuel ratio in the respective cylinder is determined in an exhaust system branch of the internal combustion engine. At least one such value is compared to a predefined value. An erroneous lift of the intake valve is diagnosed as a function of the deviation of this at least one value from the predefined value.

摘要: In an internal combustion engine, combustion air is supplied to at least one combustion chamber via at least one intake duct. The intake duct includes at least two parallel control sections, to each of which one final controlling device is allocated. Using these final controlling devices, the flow cross-section of the particular control section may be influenced. At least two final controlling devices are activated based on one single setpoint variable, and, in fact, using only one control and/or regulating system associated with the intake duct.
