Technical Examples

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.
