Abstract

See full text

An internal combustion engine having at least one combustion chamber, the internal combustion engine being connected via the exhaust thereof with an exhaust system. Disposed in the exhaust system is a heat exchanger of an exhaust heat recovery system, which can be used to transfer the waste heat of the exhaust gas to an operating fluid of the exhaust heat recovery system. Furthermore, the internal combustion engine is couplable to an air-conditioning compressor of an air-conditioning circuit. The exhaust heat recovery system has a further heat exchanger, in which the waste heat of a compressed refrigerant of the air-conditioning circuit is transferred to the operating fluid of the exhaust heat recovery system. A method for recovering the exhaust heat from such an internal combustion engine, an operating fluid of the exhaust heat recovery system being heated in a first method step by the waste heat of a compressed refrigerant of the air-conditioning circuit and, in a second method step, by the waste heat of the exhaust gas from the internal combustion engine.
