Patent ID: 8793996

Claim:
An internal combustion engine, comprising: an air intake path; a common exhaust manifold supplying exhaust gas to an exhaust gas path; a turbocharger system comprising an inlet, an outlet and at least one turbocharger having a first turbine in the exhaust gas path and drivingly connected to a first compressor disposed in the intake path and for supplying compressed air; an exhaust gas recirculation (EGR) path in fluid communication with the exhaust gas path and the intake path for directing a recirculation flow of exhaust gas to the air intake path; an EGR turbocharger comprising an EGR compressor in the EGR path and an EGR turbine; the EGR turbine having an inlet in fluid communication with a first location in the exhaust gas path and an outlet in fluid communication with a second location in the exhaust gas path, the first location being upstream of the second location, wherein the first and second locations are disposed such that, in use, the pressure difference of the gas between the inlet and outlet of the EGR turbine is less than the pressure difference of the gas between the inlet and outlet of the turbocharger system.
