Abstract
The invention relates to an internal combustion engine comprising at least two cylinders, at each of which at least one inlet for at least one combustion ingredient is provided. The engine comprises communication means, adapted to provide communication between at least a first of the cylinders, at which a first piston is provided, and a second of the cylinders, at which a second piston is provided, during at least a part of an engine operation period starting during a movement of the first piston towards a bottom dead center (BDC) position at a work stroke of the first cylinder and ending during a movement of the first piston away from the bottom dead center (BDC) position, during which engine operation period the second piston moves towards a bottom dead center (BDC) position and/or away from the bottom dead center (BDC) position.
