Method for trimming determination, particularly signal evaluation by Fourier analysis for synchronizing cylinders in internal-combustion engine, involves measuring signal by operating cycle of internal-combustion engine

摘要

The method involves measuring a signal by an operating cycle of an internal-combustion engine, implementing an order analysis, particularly a discrete Fourier transformation, of the signal, and determining an amplitude value and a phase value per order. The internal-combustion engine is controlled on the basis of trimming vector. An independent claim is included for a device for trimming determination of an internal-combustion engine.
