Internal combustion engine with an exhaust gas turbocharger
摘要:
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.
