Gas intake and exhaust system for internal-combustion engine of motor vehicle, has limiting units limiting volume flow at exit of turbine part relative to determined maximum volume flow

摘要

The system has a high pressure exhaust gas recirculation loop (30) comprising a branch (32) between an outlet of an exhaust manifold (16) and an inlet of an intake manifold (14). A temperature sensor (54) measures temperature of gases in the intake manifold. A control unit (76) controls controllable valves (38, 52) relative to sensors measurements. The control unit includes a determination unit that determines maximum volume flow in an inlet of a treatment device. Limiting units limit volume flow at an exit of a turbine part (40) relative to the determined maximum flow.
