Abstract

An internal combustion engine ( 100 ) includes a first exhaust manifold ( 120 ), and a second exhaust manifold ( 118 ) fluidly connected to the first exhaust manifold ( 120 ) through an exhaust valve ( 122 ). An exhaust gas recirculation (EGR) cooler ( 124 ) constantly fluidly connects the second exhaust manifold ( 118 ) with an intake manifold ( 112 ). A turbocharger ( 102 ) has a turbine ( 126 ) in fluid communication with the first exhaust manifold ( 120 ), and a compressor ( 132 ) in fluid communication with a supercharger ( 140 ). A charge air cooler ( 150 ) fluidly connects the supercharger ( 140 ) with the intake manifold ( 112 ).
