Abstract
An internal combustion engine, particularly suitable for a motor vehicle, is provided with a plurality of combustion cylinders, at least a first exhaust manifold and a second exhaust manifold and at least one intake manifold. Each exhaust manifold is coupled with a plurality of the combustion cylinders. Each intake manifold is coupled with a plurality of the combustion cylinders. A first turbocharger includes a first turbine having at least one inlet and an outlet, and a first compressor having an inlet and an outlet. The at least one first turbine inlet is fluidly coupled with the first exhaust manifold. A second turbocharger includes a second turbine having an inlet and an outlet, and a second compressor having an inlet and an outlet. The second turbine inlet is fluidly coupled with the second exhaust manifold and includes a controllable, variable intake nozzle. The first compressor outlet is fluidly coupled with the second compressor inlet. The engine has good fuel consumption characteristics and EGR flow rate control.
