Abstract: A turbocharged engine arrangement having an exhaust gases recirculation system (38) comprising at least: • a higher and a lower pressure exhaust-side conduit (EXHP, EXLP) • a principal intake-side conduit (INT, INTLP, INTHP) connected to the intake line; and comprising a single rotary valve (39) configured to define at least • - a higher pressure exhaust gas recirculation mode; • - a lower pressure exhaust gas recirculation mode; • -a turbine by-pass mode. Also provided is a rotary valve comprising: • at least four ports openings (58a,...) • a rotary valve body (60) having a separation wall (64) extending to divide the internal volume in two separate flow chambers (52A, 52B); wherein first and second adjacent port openings may be set in communication through one of the flow chambers, while a third port is obstructed by an obstructing sector.
