<p>The invention relates to an arrangement for supercharging a multi-cylinder internal combustion engine (1), the exhaust manifold of which engine (1) is divided into at least two separate sections (3, 4), each connected to a respective group of the cylinders of the engine. The arrangement includes at least two superchargers (5, 6), each comprising a turbine (7, 8) for connection to the outlets of exhaust manifold sections (3, 4), and a compressor (9, 10) which is driven by the turbine and the outlet of which is connected to the engine inlet manifold. The turbine (7, 8) in each supercharger (5, 6) is connected to the outlets of at least two exhaust manifold sections (3, 4) in a manner such that the pressure pulses in the exhaust gases from one section (3, 4) are supplied to the turbine (7, 8) substantially without influencing the course of the pressure in remaining sections (3, 4). A valve arrangement (25) is arranged upstream of the turbine (8), and a valve arrangement is arranged preferably upstream of the compressor (10) in at least one of the superchargers (6), this supercharger (6), or these superchargers (6), being smaller than the remaining superchargers (5).</p> |
