Determining ignition time point of internal combustion engine involves determining ignition time point from characteristic field using future load signal predicted from detected load signal

摘要

The method involves generating a characteristic field for the ignition time point depending at least on a load signal indicating the relative air filling of a cylinder of the engine, detecting the load signal at a time before the determined time point, predicting a future load signal at a later time before the determined time point; and determining the ignition time point from the characteristic field using the predicted future load signal. An Independent claim is also included for an arrangement for determining the ignition time point of an internal combustion engine.
