A twin-turbocharged internal combustion engine improves compression efficiency and improves response by serial arrangement of a first turbocharger and a second turbocharger. An exhaust gas recirculation (EGR) system using boost cooling reduces emissions of nitrogen oxides (NOx). The EGR system cools recirculated exhaust gas by exchanging heat with compressed, cooled combustion air in an EGR heat exchanger. The second turbocharger has a variable geometry turbine to control flow of recirculated exhaust gas.
1. An internal combustion engine comprising:an engine block; a cylinder head connected with said engine block; an exhaust manifold fluidly connected with said cylinder head; an inlet manifold fluidly connected with said cylinder head; a first turbocharger having a first turbine and a first compressor, an inlet portion of said first turbine being fluidly connected with said exhaust manifold through a first fluid conduit; a second turbocharger having a second turbine and a second compressor, an inlet portion of said second turbine being fluidly connected w...
