摘要： In a method for determination of a change in volumetric efficiency for an internal combustion engine, a reference volumetric efficiency is determined in advance. A first actual volumetric efficiency value which corresponds to a sensor error, is then determined at a first measurement point in a first rotational speed range in which a change in the flow losses in an intake tract has only a minor effect on the volumetric efficiency. A second actual volumetric efficiency value is determined at a second measurement point in a second rotational speed range that is greater than the first rotational speed range. The second actual volumetric efficiency value is corrected by means of the first actual volumetric efficiency value, and the change in volumetric efficiency is determined from the reference volumetric efficiency and the corrected second actual volumetric efficiency.

摘要： In a method for determining the exhaust-gas recirculation quantity for an internal combustion engine having exhaust-gas recirculation, a basic quantity of a gas mixture inducted into the engine combustion chamber(s) is determined in advance, as well as a basic pressure and/or a basic temperature of the gas mixture for at least one predefinable basic state of the combustion engine at deactivated exhaust-gas recirculation is ascertained. With the engine running, pressure and/or temperature of the inducted gas mixture are/is then determined for the current engine state at activated exhaust-gas recirculation. The currently inducted gas-mixture quantity as the basic quantity is then corrected by at least the ratio of current pressure to basic pressure of the gas mixture and/or the ratio of basic temperature to current temperature of the gas mixture. Furthermore, a fresh-gas portion of the inducted gas mixture for the current engine state is ascertained, whereupon the current exhaust-gas recirculation quantity is determined on the basis of the difference between the ascertained current gas-mixture quantity and the ascertained fresh-gas portion. The method may used in connection with diesel engines of motor vehicles, for example.

摘要： An apparatus for analyzing an analysis time signal that has been generated from encoding and decoding an original time signal according to an encoding algorithm first, wherein first the encoding block raster underlying the analysis time signal used by the encoding algorithm is determined. Thereupon, the analysis time signal will be converted from its timely representation comprising a plurality of analysis spectral coefficients, to a spectral representation by using the established encoding block raster. Then, at least two analysis spectral coefficients or at least two spectral coefficients derived from the analysis spectral coefficients by multiplication of an encoding amplification factor or by multiplication with a compression function are grouped. Then, the greatest common divisor of the analysis spectral coefficients or the spectral coefficients derived from the analysis spectral coefficients will be calculated, corresponding to the quantization step width used when quantizing the encoding algorithm or an integer multiple of it. Then, in the case of an audio signal, the scale factor can easily be established for this group of spectral coefficients, i.e. for a scale factor band, from the quantization step width. Thus, all parameters used for the quantization of the original time signal are known, so that for quantizing the analysis time signal no longer full iteration loops have to be performed, which are, on the one hand, very computing time intensive and, on the other hand, introduce tandem encoding distortions.

摘要： In a process for determining the opening time of an injection valve of a common-rail injection system, an injection duration is derived from a characteristic diagram based on the fuel quantity to be injected and the static pressure in the common rail. For reading in the characteristic diagram, the value of the static pressure in the common rail is corrected by an amount obtained from the compressional vibration of the fuel as a function of its compressibility, the injected fuel quantity during at least one preceding injection operation, and the time between the at least one preceding injection operation and the current injection operation.
