    Abstract: A fuel injection method for an internal combustion engine, an injection being implemented either in homogeneous normal operation or in inhomogeneous stratified operation. In doing so, a characteristic value for knock is detected in at least one cylinder of the internal combustion engine in inhomogeneous stratified operation. At least the one cylinder is switched over from inhomogeneous stratified operation to homogeneous normal operation if the detected characteristic value of the one cylinder meets a predetermined first criterion.

    Abstract: In a system for the closed-loop control of the supercharging of an internal-combustion engine, a manipulated variable is produced by means of a controller in dependence upon the deviation between a desired supercharging and an actual supercharging. With this manipulated variable, a final controlling element is triggered, which influences the supercharging of the internal-combustion engine. The controller parameters of the controller are repeatedly optimized. To this end, a model for the internal-combustion engine is specified, inclusive of a charging device, and the model parameters are determined from the manipulated variable and the actual supercharging. Controller parameters are determined from the model parameters and relayed to the controller. Moreover, in certain operating states, the controller parameters are stored in start-up characteristic maps. The start-up characteristic maps supply the initial values for the controller parameters each time the closed-loop control is activated.

    Abstract: The method for closed-loop knock control of a internal combustion engine, includes retarding the ignition angle when at least one cylinder knocks and then resetting the ignition angle at a later time. For internal combustion engines with a turbocharger, the method also includes reducing the boost pressure when an ignition-angle limiting value dependent on an exhaust gas temperature is reached, and then increasing the boost pressure again as soon as the ignition-angle limiting value is again crossed due to resetting of the ignition angle. The ignition angle and boost pressure values established are stored as a function of the respective operating condition of the internal combustion engine for adaptive process control and used as starting values when the same engine operating conditions are again reached.

    Abstract: An internal combustion engine, in particular for a motor vehicle, is described. The internal combustion engine is equipped with an injection valve with which fuel can be injected directly into a combustion chamber either, in a first operating mode, during a compression phase or, in a second operating mode, during an intake phase. Also provided is a control device for switching between the two operating modes and for differing open-loop and/or closed-loop control, in the two operating modes, of the operating variables influencing the actual torque of the internal combustion engine as a function of a reference torque. A change in the actual torque during a switchover is operation is detected by the control device and as a function thereof, at least one of the operating variables is influenced by the control device.

    Abstract: The method of detecting knocking of an internal combustion engine includes generating a sensor signal with a knock sensor provided with the internal combustion engine; digitizing the knock sensor signal to form a digitized signal; high-pass filtering the resulting digitized signal to form a high-frequency signal; counting amplitudes of oscillations the high-frequency signal which are greater than a first threshold value (P1) to form an amplitude count; integrating an absolute value of the high-frequency signal to obtain an integrated signal; comparing the integrated signal to a second threshold value (P2); and generating an output signal indicating that knocking is occurring when the amplitude count is at least one and when the integrated signal is greater than the second threshold value (P2).

    Abstract: An electromagnetic injection valve is proposed. The electromagnetic valve includes two magnetic coils that are wound in opposite directions and have the same characteristics on the same magnetic circuit, causing the forces of the magnetic coils to cancel each other out at the same excitation current. The two magnetic coils with canceling effect transforms the actual turn-on action of the valve, i.e., the opening of, the valve, into a turn-off action in one of the two coils. A rapid current drop is then determined by an extinction voltage. This makes it possible to achieve rapid force increase times without increasing the supply voltage. The valve can be controlled with a conventional switching output stage or with a current-regulated switching output stage. Reversing a differential current at turn-off also makes it possible to shorten the closing action.
