Zusammenfassung: | A valve and cylinder head assembly, configured to fit a bank of cylinders of an internal combustion engine, can include a first exhaust valve for each corresponding cylinder of the bank of cylinders; a second exhaust valve for each corresponding cylinder of the bank of cylinders; a first exhaust port for each corresponding cylinder of the bank of cylinders, the first exhaust port configured to direct flow of exhaust to a first manifold in fluid communication with a first turbocharger; and a second exhaust port for each corresponding cylinder of the bank of cylinders, the second exhaust port configured to direct flow of exhaust to a second manifold in fluid communication with a second turbocharger; where the shape of the first exhaust ports differs from the shape of the second exhaust ports; where each of the first exhaust valves controls flow of exhaust to a respective one of the first exhaust ports; and where each of the second exhaust valves controls flow of exhaust to a respective one of the second exhaust ports. Various other devices, assemblies, controllers, etc., are also disclosed. |
