Abstract
Herein an internal combustion engine, ICE, (2) is disclosed. The ICE (2) comprises a second valve (40) arranged in an exhaust conduit (6). The exhaust conduit (6) extending from an exhaust valve (26) to an inlet of a turbine (8). The second valve (40) is configured to close and open the exhaust conduit (6). The second valve (40) is opened after the exhaust valve (26) has started to open. The second valve (40) has a faster valve area opening speed than the exhaust valve (26).
