Engine system and method including first and second turbochargers
An engine system includes an internal combustion engine having an intake passage, a first set of combustion chambers, a second set of combustion chambers, a first exhaust passage fluidly connected to the first set of combustion chambers, and a second exhaust passage fluidly connected to the second set of combustion chambers. The engine system includes a first turbocharger including a first compressor and a first turbine. The engine system also includes a second turbocharger including a second compressor and a second turbine, the second compressor connected in series with the first compressor, and the second turbine being in fluid communication with the second exhaust passage. The first and second turbines are connected in parallel such that the first turbine only receives exhaust flow from the first set of combustion chambers, and the second turbine only receives exhaust flow from the second set of combustion chambers.
