Claim Text:
1. A turbocharged power unit, comprising: a first stage turbocharger including a turbine coupled via a turbocharger shaft to a compressor, the compressor configured to receive an ambient intake air stream and discharge a compressed air stream; an intercooler coupled to an output of the compressor of the first stage turbocharger, the intercooler configured to receive the compressed air stream from the compressor of the first stage turbocharger and discharge a cooled compressed air stream; a second stage turbocharger including a turbine and a compressor coupled to the turbine via a turbocharger shaft, the compressor configured to receive the cooled compressed air stream from the intercooler and discharge a further compressed air stream and wherein the turbine is in fluidic communication with the further compressed air stream from the compressor of the second stage turbocharger and configured to discharge an expanded air stream; an engine including an intake manifold, a combustion chamber and an exhaust manifold, wherein the intake manifold is coupled to the turbine of the second stage turbocharger to receive therefrom the expanded air stream and wherein the combustion chamber is in fluidic communication with the intake manifold and the exhaust manifold; and a bypass valve coupled to an electronic logic control unit and configured in fluidic communication with one of: wherein the turbine of the second stage turbocharger is configured to provide an expansion of the cooled compressed air stream to form the expanded air stream having a temperature of less than the ambient intake air stream.
