摘要： Method for controlling boost pressure in an internal combustion engine, using a boost pressure control device by means of which from the control deviation between a setpoint boost pressure and an actual boost pressure a manipulated variable is generated which has a D portion supplied by a differential control unit or a damper, the D portion being adapted as a function of a control deviation of a transient effect detected and evaluated for a predetermined evaluation time period, wherein the D portion adaptation includes an operating point-dependent D portion depth adaptation and/or an operating point-dependent D portion time adaptation, whereby the output variable for the differential controller is adapted by the D portion depth adaptation, and the operating time of the D portion corresponding to predetermined boost pressure parameters, in particular characteristic map parameters, is adapted by the D portion time adaptation.

摘要： The invention relates to an internal combustion engine with at least one cylinder which has at least two exhaust valves which are connected to exhaust gas lines in which there are the turbines of the exhaust gas turbochargers which have compressors for the charging air of internal combustion engines. It is provided that downstream from the compressors there is a merge (23) for the charging air flows (21) of the compressors and that there is at least one externally controllable valve (25) downstream from at least one of the compressors and upstream from the merge (23).Furthermore, the invention relates to a method for operating such an internal combustion engine. It is provided that downstream from the compressors the charging air flows of the compressors are merged and that at least downstream from one of the compressors and upstream from the merge, externally controllable blocking or choking of at least one of the charging air flows can take place.

摘要： The invention relates to a method for controlling boost pressure in an internal combustion engine, using a boost pressure control device by means of which from the control deviation between a setpoint boost pressure and an actual boost pressure a manipulated variable is generated which has a D portion supplied by a differential control unit or a damper, the D portion being adapted as a function of a control deviation of a transient effect detected and evaluated for a predetermined evaluation time period. According to the invention, the D portion adaptation, performed in particular for adapting the boost pressure pulse duty factor for a boost pressure control valve, includes an operating point-dependent D portion depth adaptation and/or an operating point-dependent D portion time adaptation, whereby the output variable for the differential controller is adapted by means of the D portion depth adaptation, and the operating time of the D portion corresponding to predetermined boost pressure parameters is adapted by means of the D portion time adaptation.

摘要： A method for diagnosing an exhaust-gas recirculation system of an internal combustion engine provides that the fuel quantity, which is needed for a desired mixture composition, is computed, at least approximately, in a control apparatus from at least stored data of the EGR system. The stored data can be in the form of a through-flow characteristic line. Thereafter, the fuel quantity is corrected by a control factor in dependence upon the mixture composition. The control factor is computed and stored when the EGR system is switched on and the control factor is computed and stored when the EGR system is switched off. The difference of these control factors is then formed and compared to pregiven values. A fault signal is outputted in the event of a deviation.

摘要： A method and an arrangement for controlling an internal combustion engine (1) are introduced and have actuators (3), which influence at least one control parameter relevant for the consumption of fuel of the engine. A control appearance forms an index L for the run-in state of the engine. The drive signals y of the actuators (3) are changed in dependence upon the above-mentioned index L in a predetermined manner.
