Method for controlling the temperature of an exhaust gas recirculation cooler of an internal combustion engine arrangement and combined temperature control device for an internal combustion engine arrangement

摘要

The invention relates to a method for tempering an exhaust gas recirculation cooler (30, 130) of an internal combustion engine arrangement (10). Heat is transferred between an exhaust gas flow (22), which is emitted by an internal combustion engine (20) of the internal combustion engine arrangement (10), and a secondary side (34, 134) of the exhaust gas recirculation cooler (30, 130) by means of the exhaust gas recirculation cooler. Furthermore, heat is transferred between an air supply flow (21), which is delivered to the internal combustion engine (20), and a secondary side (44, 144) of an intercooler (40, 140) by means of the intercooler. It is provided that heat is transferred between the secondary side (34) of the exhaust gas recirculation cooler (30) and the secondary side (44, 144) of the charge air cooler (40, 140), whereby the exhaust gas recirculation cooler (30, 130) through the between the secondary sides (44 , 144) transferred heat is tempered. The invention further relates to a combined temperature control device (10) set up for temperature control of an exhaust gas flow (22) and an air supply flow (21) of an internal combustion engine (20). The temperature control device (10) is designed to carry out the method.
