Title: INTERNAL COMBUSTION ENGINE HAVING A HEAT TRANSPORT DEVICE FOR TRANSPORTING HEAT FROM AN EXHAUST-GAS RECIRCULATION PATH INTO AN EXHAUST-GAS TRACT
Abstract:
The invention relates to an internal combustion engine (1) having a supercharging path (3) designed for feeding charge air to at least one combustion chamber (5) of the internal combustion engine (3), having an exhaust-gas tract (7) designed for discharging exhaust gas from the at least one combustion chamber (5), and having an exhaust-gas recirculation path (9) which connects the exhaust-gas tract (7) outside the at least one combustion chamber (5) to the supercharging path (3), such that exhaust gas can be fed from the exhaust-gas tract (7) to the supercharging path (3). Here, a heat transport device (11) is provided which has a heat absorption device (13) which is designed and arranged to absorb heat from the exhaust-gas recirculation path (9), wherein the heat transport device (11) is designed to introduce heat extracted from the exhaust-gas recirculation path (9) into the exhaust-gas tract (7) downstream of a branching-off point (15) of the exhaust-gas recirculation path (9) from the exhaust-gas tract (7).
