Abstract
Abstract An internal combustion engine includes an exhaust manifold; an intake manifold; and a turbocharger including a turbine in communication with the exhaust manifold, and a compressor in communication with the intake manifold. An electrical generator is coupled with the turbine. A motor receives electrical input power from the generator and provides mechanical output power. A combustor selectively provides additional input power to the motor.
