ABSTRACT:
An engine has a plurality of cylinders each having an exhaust-gas output. An exhaust-gas turbocharger has a plurality of exhaust-gas inlets which are connected via respective exhaust-gas conduits to the outlets of the cylinders, with each conduit connected to one or more of the cylinders. A vent conduit connects at least one of the exhaust-gas conduits to the output side of the exhaust-gas turbocharger and is provided with a valve that releases pressure in the respective conduit when pressure in the exhaust system or engine speed exceeds a predetermined limit. Furthermore this one conduit is of restricted flow-cross-section so that at low engine speed the gas velocity in the conduit is high for driving the turbocharger, but at high engine speed pressure is relieved to prevent overdriving of the turbocharger.
