    摘要： The invention is directed to a method and an arrangement for determining a fuel wall film mass in an internal combustion engine (1) having intake manifold injection. The method and arrangement provide a precise as possible transition compensation also for the case wherein the fuel injection into the open inlet valve (5) of a cylinder (20) takes place. The fuel wall film mass is determined starting from a fuel injection which takes place completely in advance of opening of the inlet valve (5) of the cylinder (20) of the internal combustion engine (1) into the intake manifold (10). The value so determined for the fuel wall film mass is corrected in dependence upon the ratio between the fuel mass, which is injected via the open inlet valve (5) into the combustion chamber (15) of the cylinder (20), and the total injected fuel mass.

    摘要： To operate a steplessly adjustable camshaft control device, particularly reliably and safely, an adaptation of the camshaft and the crankshaft is performed so that a phase angle (actual value) of the camshaft to the crankshaft is determined, the phase angle is monitored while operating the internal combustion engine and the camshaft control device is controlled as a function of a variable setpoint value so that the phase angle is equivalent to the setpoint value.

    摘要： A method and a device for operating an internal combustion engine having multiple cylinders allows for an operating state of the internal combustion engine to be switched over as quickly as possible following the receipt of a switchover request. For this purpose, at least one intake or exhaust valve of a cylinder is switched off or at least one switched-off intake or exhaust valve of the cylinder is switched on again in at least one operating state of the internal combustion engine in response to the switchover request.

    摘要： In a method for operating a camshaft adjusting device, using an actuating drive, the actual setting of a camshaft with respect to the rotation of the crankshaft is followed corresponding to a setpoint setting ascertained in a control unit. In response to the occurrence of a lasting system deviation between the actual setting and the setpoint setting, an error signal is generated. The error signal is designed in multiple stages as a function of the system deviation, different weightings being imputed to the individual stages of the fault indication. By this measure, the fault indications of different weightings may be processed. Faults that are not serious, but nevertheless require attention, may be treated separately from serious faults.

    摘要： A method and a device for operating an internal combustion engine, which make possible a defined and reliable cutting in or cutting off a gas-exchange valve of a cylinder. In at least one operating state, at least one intake valve or exhaust valve of a cylinder is cut off or at least one cut-off intake valve or exhaust valve of the cylinder is cut in again, the at least one intake valve or exhaust valve being opened and/or closed using an operating element; and the operating element being switched off or switched on again using a coupling element. A response delay time is ascertained which is required for the operation of the coupling element for the switching off or switching on again the operating element. Furthermore, a switching time window is ascertained within which the operation of the coupling element is desired. Moreover, it is checked whether the switching time window is greater than the response delay time. In this case, a beginning of the switching procedure for cutting off or cutting in again the at least one intake valve or exhaust valve is established in such a way that the response delay time lies completely within the switching time window.
