  • Patent number: 11156191
    Abstract: An internal combustion engine having two “banks” of cylinders, the “banks” being defined by cross-connection to different turbochargers. The exhaust from one bank of cylinders goes to a first turbocharger, and the exhaust from the other bank of cylinders goes to a second turbocharger. However, the compressed air delivered from the turbochargers is cross-connected to the cylinder banks. This allows a cylinder bank to be boosted with a turbocharger whose compressed air output does not necessarily match the exhaust energy of that cylinder bank.
