Abstract:
The disclosure concerns variable valve timing of a four-stroke ICE. The ICE comprises: an exhaust valve and an intake valve an exhaust camshaft an intake camshaft and a cylinder arrangement. The cylinder arrangement comprises a combustion chamber a cylinder bore and a piston. The control arrangement is configured to: perform a first sequence of changes in the timings of the exhaust and intake camshafts in order to arrive from a first camshaft timing setting at a second camshaft timing setting based on a first current maximum cylinder pressure within the combustion chamber around top dead centre fire and/or around to dead centre gas exchange.
