DrehzahlLastfenster
DrehzahlLastfenster is a term used in engine development and calibration to describe a two‑dimensional region of operation defined by engine speed (Drehzahl) and engine load (Last). It represents a portion of the engine map where data are collected, analyzed, and used to tune control strategies. The concept helps engineers focus on representative conditions for performance, efficiency, and emissions.
The window is defined along two axes: Drehzahl, commonly given in revolutions per minute (U/min), and Last,
Applications of a DrehzahlLastfenster include ECU calibration, fuel injection timing, ignition timing, boost control, exhaust aftertreatment
Limitations should be noted: the window covers only a subset of the full operating envelope and may
