Abstract

A device for reducing corrosive constituents in an exhaust gas condensate of an internal combustion engine is provided, in which the exhaust gas of the internal combustion engine is recirculated to the internal combustion engine via an exhaust gas recirculation system having an exhaust gas cooler and at least one exhaust gas recirculation line. To protect the exhaust gas recirculation system along with intake air components and the internal combustion engine from the corrosive effects of the exhaust gas condensate, the exhaust gas recirculation system has at least one neutralization unit for neutralizing the corrosive constituents of the exhaust gas condensate, which is connected to at least one component arranged downstream, through which the exhaust gas, which has been freed of nearly all corrosive constituents, flows.
