Abstract (en)
[origin: WO2013079427A1] The invention relates to an internal combustion engine (1): with an arrangement for feeding back exhaust gas and supplying cooled charge air to an internal combustion engine (1), wherein the internal combustion engine (1) comprises an exhaust gas supercharging system (6, 7) and an exhaust gas cooling system (16); with an exhaust gas cooling system (16) having a single or double stage exhaust gas cooler with a first cooling stage (20) and optionally a second cooling stage (21); with at least one bypass (17) for circumventing the first and/or the second cooling stage of the exhaust gas cooler (16); with at least one exhaust gas control valve (15); with at least one intercooler (25) and a bypass (30) for circumventing the first intercooler (25); and with a charge air control valve (28), wherein the components of the arrangement that come into contact with an acidic condensate produced in the exhaust gas cooler (16) and/or in the intercooler (25) previously undergo an immunising treatment such that they resist the condensate.
