Abstract:
The disclosure concerns a method and a control arrangement for controlling valve actuation of an ICE comprising an exhaust valve, an intake valve, and a turbo compressor. The method comprises and the control arrangement is configured to: limiting/limit valve actuation changes of the exhaust and intake valves based on compressor data including surge limit data for the turbo compressor and one or both of a current turbo compressor rotational speed and a current turbo compressor pressure ratio, to maintain a turbo compressor mass flow above a limit mass flow value.
