Supercharged internal combustion engine with two separate exhaust manifolds (2a,2b) from individual cylinder groups and two separate inlet manifolds (3a,3b) each leading to a respective cylinder group. An inlet conduit (9) from a supercharger (6) leads to an equalising chamber (11), from which two tuned resonance tubes (12,13) lead to the inlet manifolds. From the exhaust manifolds a pair of exhaust recirculation conduits (19a,21a,19b,21b), each containing a control valve (18a,18b) controlled by a control unit (16) for controlling the exhaust recirculation, lead to the inlet manifolds. The control unit is disposed to open the control valves when the exhaust pressure is higher than the pressure in the inlet manifolds. |
