Abstract: A turbocharged engine includes an internal combustion engine and a turbocharger powered by engine exhaust flow from the internal combustion engine to supply the engine with compressed intake air. The turbocharged engine further includes a turbocharger booster system with a dry low emissions burner. The burner fluidly communicates with an exhaust manifold of the engine and is operable to inject a combustion gas flow into the engine exhaust flow. The hot combustion gas flow is operable to increase the exhaust energy available to the turbocharger and thereby increase the output of compressed intake air.
