| 摘要 |
The invention relates to an internal combustion engine (1) comprising an exhaust gas recirculation system (5) arranged between an inlet system and an outlet system (2, 4), said exhaust gas recirculation system (5) comprising an EGR line (11) branching off from the outlet system (4) and arranged upstream of an exhaust gas turbine (7, 8) of at least one exhaust gas turbocharger (9, 10). At least one EGR cooler (16) is arranged in the EGR line (11). At least one first EGR cooler (16) is embodied as an exhaust gas/exhast gas-heat exchanger having an EGR flow path (26) and a first coolant flow path (25) which is connected to the outlet system (4) downstream of the exhaust gas turbine (7, 8). In order to improve the cooling of the recirculated exhaust gas, without adding additional heat into the coolant system of the vehicle, a second coolant flow path (28) is provided and connected to a cooling air line (41). |
