    摘要： A method is used for activating an actuator to set a turbine flow cross-section of a motor vehicle turbocharger of a gasoline engine in the event of a change of the load of the engine from a smaller load value to a larger load value. The actuator for the larger load value is activated with a delay in relation to the load change. Furthermore, a control unit set up to control the sequence of the method is used to implement the method.

    摘要： A process controls filling of combustion spaces of an internal combustion engine that has at least one filling control element and one exhaust gas turbocharger whose turbine geometry can be adjusted by an electrical positioning element. In a base position of an electrical positioning element, a basic charging pressure is provided. When there is a possible or actual faulty displacement of the electrical positioning element, filling of the combustion spaces is limited by driving the filling control element. A control device controls the execution of the process.

    摘要： A method is introduced for controlling a turbocharger that generates a charging pressure in an intake plenum. The charging pressure is controlled on the turbine side, and the turbocharger has a circulating-air valve that temporarily opens a flow-cross section between the intake plenum and a suction side of the turbocharger when an air mass flow flowing out of the intake plenum is reduced. Under certain operating conditions, in addition to the turbine-side control by adjusting a turbine flow cross-section, the charging pressure is reduced by opening the circulating-air valve. Furthermore, a control device is introduced that implements the process.

    摘要： A method is introduced for controlling a turbocharger that generates a variable charging pressure for an internal-combustion engine by using a controllable turbine flow cross-section and whose turbine flow cross-section, when an increased charging pressure is demanded, is temporarily reduced and increased again. A measure for an exhaust gas mass flow through the turbine flow cross section is formed and the enlargement of the turbine cross-section takes place as a function of that measure. In addition, a control device is introduced that implements the method.

    摘要： A data exchange system permits data transfers where both the length of the data words, and the speed of change of the information represented by the data, can both vary considerably. A central station is connected to an interface circuit, which in turn is radially connected by four-wire conductors or lines to a number of sub-units. Each sub-unit is in turn connected by a bus to a number of modules or sub-assemblies. The interface circuit contains a microcomputer and a coupler circuit. Each sub-unit contains a switching stage, a control logic circuit, and a number of shift registers.
