Abstract
A method for controlling an automotive internal combustion engine having direct fuel injection is described, with the method comprising a fuel adaption part in which a fuel quality parameter (F) is determined using a first fuel quality parameter determination procedure when the engine exhibits predetermined operation conditions and a control part which uses the value of the fuel quality parameter (F) or of a fuel combustion characteristics parameter derived from the fuel quality parameter (F) as a target value (αT) in a closed-loop control of the start of injection (SOI) at the engine, with the closed-loop control using a second fuel quality parameter determination procedure being different from the first fuel quality parameter determination procedure to determine an actual value (αA) of the fuel quality parameter (F) or of the fuel combustion characteristics parameter derived from the fuel quality parameter (F).
