Abstract
A turbocharged internal combustion engine is operated such that the intake manifold pressure generally exceeds the exhaust manifold pressure. A low pressure turbocharger and a high pressure turbocharger are provided in series. An exhaust gas recirculation (EGR) system passively routes a portion of the exhaust gases to the high pressure turbocharger compressor inlet.
