The cooling system for air fed to IC engines and exhaust gases from them comprises a high temperature circuit and a low temperature circuit. Air is fed through a first heat exchanger (3) and recirculated exhaust gas through a second exchanger (4). Each of the exchangers has a high temperature section (31a, 31b, 41a, 41b) connected to the high temperature circuit, so that high temperature coolant circulates through them and a low temperature section (32a, 32b, 42a, 42b) connected to the low temperature circuit to allow low temperature coolant to circulate. |
