Abstract: In an internal combustion engine with an exhaust gas turbocharger comprising a charge-air pipe and an exhaust gas recirculation pipe for a partial stream of the exhaust gas, a nozzle-diffuser unit is provided in the charge-air pipe, into which unit the recirculation pipe opens in a passage of restricted cross-section. In order to achieve high turbine efficiency as well as high exhaust quality, it is provided in the invention that the exhaust gas turbocharger be configured at least as a twin-entry unit, and that at least two exhaust gas flow paths be conducted separately to the entrance into the exhaust gas turbocharger, and that an exhaust gas recirculation branch depart from each exhaust gas flow path, and further that a control valve be positioned in each recirculation branch for regulation of the exhaust gas recirculation.

Abstract: In order to utilize recycling of exhaust gases at high engine loads in an internal-combustion engine with an exhaust gas turbocharger, optionally with a charge cooler, as well as an exhaust gas recycling valve which is arranged within a connecting pipe through which a partial exhaust gas stream flows, the connecting pipe, in the direction of the flow, branching from the exhaust pipe upstream of the exhaust gas turbine and connecting into the charge pipe downstream of the exhaust gas turbine, an apparatus is employed which injects water into the partial exhaust gas stream flowing the connecting pipe at operating temperature and at high load operation of the internal-combustion engine.
