    • 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).
    • 内燃机可包括具有高温冷却器(50)的排气再循环管线(80,82,84,86),排气压缩机(70),低温冷却器(55)和控制单元 60)。 控制单元(60)可以被配置为根据冷却性能/发动机操作模式信息来控制高温冷却器(50)的冷却性能,使得在高温冷却器的出口处提取的废气的温度 (50)可以独立于发动机操作模式保持在高于硫酸露点的温度。 对于发动机的低硫燃料操作,以所提出的方式操作高温冷却器(50)允许主要在低温冷却器(55)中处理严重的结垢和堵塞问题。

    • The present disclosure relates to a cooling system (100) for an internal combustion engine (102) including a cylinder unit (114). The cooling system (100) comprises a cooling circuit portion (104) configured to circulate a flow of coolant. The cooling circuit portion (104) includes a cooling circuit portion outlet (118) and a cooling circuit portion inlet (120). The cooling circuit portion outlet (118) and the cooling circuit portion inlet (120) define a flow direction of coolant within the cooling circuit portion (104) from the cooling circuit portion inlet (120) to the cooling circuit portion outlet (118). The cooling system (100) further comprises a charge air cooler (106) configured to transfer heat from charge air to the coolant. The charge air cooler (106) includes a first charge air cooler port (130) and a second charge air cooler port (132). The cooling system (100) further comprises a cylinder cooling jacket (108) configured to transfer heat from the cylinder unit (114) to the coolant. The cylinder cooling jacket (108) includes a cylinder cooling jacket inlet (148) and a cylinder cooling jacket outlet (150). In a first cooling configuration of the cooling system (100), the cooling circuit portion outlet (118) is connected to the first charge air cooler port (130), the second charge air cooler port (132) is connected to the cylinder cooling jacket inlet (148), and the cylinder cooling jacket outlet (150) is connected to the cooling circuit portion inlet (120). In a second cooling configuration of the cooling system (100), the cooling circuit portion outlet (118) is connected to the cylinder cooling jacket inlet (148), the cylinder cooling jacket outlet (150) is connected to the second charge air cooler port (132), and the first charge air cooler port (130) is connected to the cooling circuit portion inlet (120).
