    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： This invention relates to a method for determination of a change in volumetric efficiency for an internal combustion engine, whereby a reference volumetric efficiency is determined in advance, a first prevailing volumetric efficiency which corresponds to a sensor error is determined at a first measurement point (M1, L1) 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 prevailing volumetric efficiency at a second measurement point (M2, L2) in a second rotational speed range is determined, this rotational speed range being above the first rotational speed range in terms of rotational speed, the second prevailing volumetric efficiency is corrected by means of the first prevailing volumetric efficiency and the change in volumetric efficiency is determined from the reference volumetric efficiency and the corrected second prevailing volumetric efficiency. The inventive method is preferably used in a control/regulation of an exhaust gas recirculation rate.

    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.
