摘要

Method for adjusting an injection system (4) of a combustion engine (1) comprises preparing a combustion engine with an injection system, selecting an injection unit (5) of the system assigned to a cylinder (3), determining an injection period value for controlling the injection unit, controlling the injection unit using the injection period value to inject fuel (6) into the cylinder, determining a digital measuring signal which characterizes the combustion of fuel in the cylinder, transforming the digital measuring signal into a frequency region and evaluating the measuring signal. An independent claim is also included for a device for adjusting an injection system of a combustion engine. Preferred Features: The digital measuring signal is transformed using a discrete Hartley transformation. The measuring signal is evaluated using spectral analysis of low frequency spectral components of the measuring signal.
