Zusammenfassung:	The disclosure concerns a method for vibration reduction in a compression ignition four- stroke internal combustion engine. The internal combustion engine comprises exhaust and intake valves controlled by exhaust and intake camshafts. The method comprises, when operating the internal combustion engine below a threshold rotational speed, steps of: changing a timing of the exhaust camshaft to advance closing of the exhaust valve, and - changing a timing of the intake camshaft to delay opening of the intake valve.
