An internal combustion engine comprises a first exhaust manifold, a second exhaust manifold, a first turbocharger having a first turbine and a first compressor, and a second turbocharger having a second turbine and a second compressor. A second gas inlet port of the second turbine is connected in fluid communication with a second exhaust manifold to receive at least a portion of second combustion gases. A second gas outlet port of the second turbine and the first exhaust manifold are in fluid communication with a first gas inlet port of the first turbine. A valve is connected in fluid communication with the second exhaust manifold to receive a remainder of exhaust gases not included in the at least a portion of the second combustion gases supplied to the second turbine. The valve is connected in fluid communication with a mixer to deliver at least a portion of the remainder of exhaust gases to the mixer for mixing with compressed air in the mixer.
