Abstract
In an internal combustion engine including an exhaust turbocharger and an exhaust-gas recirculation device, with an exhaust turbine and a compressor, the exhaust turbine has a plurality of inlet flow passages to which exhaust gas can be supplied via separate exhaust lines connected to some of the cylinders of the internal combustion engine. In total, three flow passages are provided in the exhaust turbine, of which two communicate with the exhaust-gas recirculation device, and one of these flow passages includes an adjustable throttling member for regulating the mass flow of exhaust gas to be recirculated.
