Method and Control Arrangement for Controlling Four-Stroke Internal Combustion Engine

The disclosure concerns a method (100) for controlling a four-stroke internal combustion engine (4), and comprises steps of:- setting or determining (102) an initial timing setting of the exhaust camshaft (10) and/or the intake camshaft (12), - providing (104) an alternating control signal for the e...

Zusammenfassung:	The disclosure concerns a method (100) for controlling a four-stroke internal combustion engine (4), and comprises steps of:- setting or determining (102) an initial timing setting of the exhaust camshaft (10) and/or the intake camshaft (12), - providing (104) an alternating control signal for the exhaust camshaft (10) and/or the intake camshaft (12) in order to generate an oscillating change of a timing of the exhaust camshaft (10) and/or the intake camshaft (12), and - controlling (106) the internal combustion engine (4) in accordance with a first mode of operation or a second mode of operation different from the first mode of operation in response to at least one change in the timing of the exhaust camshaft (10) and/or the intake camshaft (12) resulting from the alternating control signal.
