The invention relates to a radio receiving system (100), comprising a Radio Data System radio receiver (RDS radio receiver (10)) with an RDS processor (12) and several receiving antennas (14), which are connected to the RDS radio receiver (10) via an antenna change-over system (12). Said antenna change-over system (12) is directly connected to the RDS processor (16) by a control device (36, 34) in order to carry out change-over operations from one receiving antenna (14) to another (14).
摘要:
In a device for adjusting the injection timing in a diesel engine fitted with EDC a basic value (SBGWs) of injection timing for operation in the static or steady state is stored in a first characteristic field (20) and a basic value (SBGWd) for operation in the dynamic or unsteady state (acceleration, deceleration) is stored in a second characteristic field (22). These basic values are dependent on desired injected fuel quantity (Q) and engine speed (n). The characteristic field (20) for the static state is designed empirically or otherwise to optimise fuel consumption whereas that (22) for the dynamic state is designed for minimum pollutant emission. A gradual changeover from one mode to the other is achieved by the gradual change of a multiplying factor (c) from 0 to 1 or vice versa responsively to dQ/dt departing significantly from zero or becoming zero.

The invention relates to a device and a method for controlling an internal combustion engine. A quantity of oxygen (MO22) which flows into the internal combustion engine is detected by means of at least one model and according to at least one correcting variable and at least one measuring variable which characterises the state of the air in a suction pipe. The quantity of oxygen (MO22) is detected according to at least a temperature variable (T2), a pressure variable (P2), a speed variable (N), a fuel quantity variable (ME) and an air variable (ML21).

The invention relates to a method and to a device for controlling an internal combustion engine that is provided with an air system. At least one value that characterizes the air system is determined by means of a model, on the basis of at least one correcting variable and/or at least one measured variable that characterizes the condition of the ambient air. The inventive model comprises at least one first and one second submodel. The starting values are determined by means of a submodel on the basis of input values. The correcting variable and/or the measured variable, in addition to at least one starting value of a second submodel, are taken into account for the input values of the first submodel.

摘要:
The geometry of the exhaust gas turbocharger turbine (4) located in the exhaust gas channel (3) of the internal combustion engine (1) is variable. The boost pressure (pld) can therefore be regulated by changing the turbine geometry. The boost pressure regulation system reacts very quickly to a change in load since a correcting variable (vtg) for the turbine geometry is determined depending on the exhaust gas counterpressure (pag) present in the exhaust gas channel (3) ahead of the turbine. This prevents the exceeding of a desired value, which would damage the turbocharger.
