摘要： In an internal combustion engine, at a first operating point using no exhaust gas recirculation, a first measured value of a load variable is detected. As a function of a further operating variable, a first model value of the load variable is determined using a suction pipe model. At least one parameter of the suction pipe model is adapted such that the first model value approaches or corresponds to the first measured value. A first value of the parameter adjustment is stored. At a second operating point, using exhaust gas recirculation a second value corresponding to the first value of the parameter adjustment, is determined and stored. The first and second values of the parameter adjustment are compared and a parameter value of an exhaust gas recirculation model is adapted such that the first and the second values of the parameter adjustment approach each other or correspond to each other.

摘要： An internal combustion engine has an intake tract having a compressor. A verification is performed as to whether at least one predefined activation condition is met. A boost pressure (PUT) downstream of the compressor is sensed or determined. An adaptation characteristic curve or adaptation characteristic map (KF_AD) is adapted as a function of a rotational speed (N) of the internal combustion engine and the boost pressure (PUT) if the at least one actuation condition is met. A gradient is determined that is representative of a gradient of the adaptation characteristic curve or adaptation map (KF_AD). From the determined gradient, conclusions are drawn with respect to a fault in the intake tract of the internal combustion engine.

摘要： In order to operate an internal combustion engine with a turbocharger, a boost pressure prevailing downstream of a compressor (42) of the exhaust gas turbocharger and upstream of a cylinder intake port of the internal combustion engine is regulated to a predefined desired boost pressure value (PUT_SP). An actuation signal portion (DELTA_PWM_WG) of a controller for regulating the boost pressure to a desired boost pressure value (PUT_SP) is determined. A change in the turbocharger speed (DELTA_N_TCHA) associated with the actuation signal portion (DELTA_PWM_WG) of the controller is determined in accordance with the actuation signal portion (DELTA_PWM_WG) of the controller and an operating point of the internal combustion engine. A turbocharger speed limit (N_TCHA_MAX) is determined in accordance with the determined change in the turbocharger speed (DELTA_PWM_WG).

摘要： Actual values of a load variable are detected by a sensor during active model trimming under different valve pressure conditions, and a model of estimated values is created. Trimming values of a model parameter are determined depending on detected and modeled values such that when the model parameter is trimmed, the modeled values approximate the detected values. A function is determined depending on the different pressure conditions and approximated to the trimming values. At different pressure conditions first lambda control values are detected. A first controller value fitted function is determined depending on the pressure conditions and approximated. When the model trimming mode is not active, second lambda control values are detected at different pressure conditions. A second controller value fitted function is determined depending on the pressure conditions and is approximated. An error of the intake system is detected depending on the fitted functions.

摘要： An internal combustion engine has an intake system (1) and an exhaust gas system (4). An exhaust turbocharger of the internal combustion engine has a compressor (42) arranged in the intake system (1) and a turbine (48) arranged in the exhaust gas system (4) of the internal combustion engine for driving the compressor (42). In order to diagnose the intake system (1), a charge pressure (PHS_AIC_DOWN) of the compressor (42) is determined in a predetermined operating state of the internal combustion engine. A leakage of the intake system (1) downstream of the compressor (42) is recognized if the determined charge pressure (PHS_AIC_DOWN) is lower than the predetermined base charge pressure (PUT_BAS) in the predetermined operating state.
