Kühlsystem für eine Brennkraftmaschine

摘要

A cooling system for an internal combustion engine has an engine cooling circuit with an engine radiator 1, a fresh-air supply conduit 10, which leads to the internal combustion engine 4, in which an exhaust gas turbocharger 12 is arranged, an exhaust gas return conduit 15, in which a cooling device 5 is placed. The cooling device 5 is integrated into the engine cooling circuit and device 5 is connected to the engine cooling circuit conduits 6, 19 via at least one branch conduit 7 and return conduit 8. In one embodiment a pump is used to circulate cooling medium to cooling device 5 (figure 2) and in another embodiment the cooling device 5 has its own radiator (figure 3). Exhaust gas conduit 15, after passing through the cooling device 5, opens into the fresh air supply conduit 10 leading to the supply conduit. Energy extracted by cooling device 5 may be used to heat the vehicle interior.
