Method for determining engine characteristic map data of combustion engine, involves carrying out engine measurement using ascending and descending parameter values, and evaluating measured values to determine engine characteristic map data

摘要

The method involves carrying out engine measurement using continuously ascending and descending parameter values of a parameter (x), and evaluating the corresponding measured values to determine the engine characteristic map data depending on the parameter values. The change in the parameter values of the parameter is carried out with different changing rates. The measurement errors of primary and secondary orders are eliminated from the corresponding measured values by averaging or other mathematical combination of the measured values.
