Abstract

The present disclosure relates to an internal combustion engine (ICE) system (10) for a vehicle (1), the ICE system comprising: a two-stroke ICE (20) operable on a fuel (50), the ICE having at least one cylinder (30) with a cylinder wall (30a) and further a reciprocating piston (31) moveable in an axial direction (A) within the cylinder between a bottom dead center (BDC) and a top dead center (TDC), the at least one cylinder at least partly defining a combustion chamber with a top end (33) of the piston; a first intake manifold (22) for receiving fresh air, the first intake manifold configured to be in fluid communication with a first intake port (35) arranged at a top end (36) of the at least one cylinder; an exhaust port (38) arranged axially distal from the top end of the at least one cylinder; a second intake manifold (86) configured to be in fluid connection with an exhaust gas recirculation (EGR) system (80), the second intake manifold further being configured to be in fluid communication with a second intake port (87) arranged at the top end of the at least one cylinder, the second intake port being configured to be in fluid communication with the combustion chamber, wherein the flow of gas through the second intake port is controllable by a controllable EGR control valve (88); the EGR system further having an EGR conduit (81) arranged to connect an exhaust duct (61) of the ICE system to the second intake manifold, wherein the EGR system further comprises a positive displacement device (82) configured to direct EGR gas to the second intake manifold, and an EGR cooler (89) for regulating the temperature of the EGR gas.
