Exhaust gas recirculation for large internal combustion engines

An internal combustion engine may comprise an exhaust gas recirculation line (80, 82, 84, 86) with a high temperature cooler (50), an exhaust gas compressor (70), a low temperature cooler (55), and a control unit (60). The control unit (60) may be configured to control the cooling performance of the high temperature cooler (50) in accordance with a cooling performance/engine operation mode information such that a temperature of the extracted exhaust gas at an exit of the high temperature cooler (50) may be maintained at a temperature above a dew point of sulphuric acid independently of the engine operation mode. For low sulphur fuel operation of the engine, operating the high temperature cooler (50) in the proposed manner allows handling severe fouling and blocking issues primarily in the low temperature cooler (55).
