Method to determine an average amplitude of air mass flow fluctuations

摘要

The reporting process reports the mean amplitude of air mass oscillations on the basis of an air mass signal (A) in the induction manifold of a charging device to control the intended charging pressure of the charging device for an internal combustion engine, such as an exhaust gas supercharger for a vehicle diesel engine in two paths (1, 2) on the basis of the gradient (B) of the air mass signal to form a first mean value (D), then forming a difference signal (G).
