Abstract

A motor vehicle provided with a combustion engine, an alternator, a battery and a heating installation for the passenger cabin has a heating unit which comprises a heating circuit and a heating exchanger fed by the heating liquid for the heating of air. The alternator is liquid cooled and has a rotor and chambers adapted to receive cooling liquid and is switchable into the heating circuit; and the alternator has filed coils adapted to be short circuited. In this fashion the alternator is switchable as an eddy current brake. Furthermore, the alternator may be a liquid cooled alternator asynchronous generator, whereby its chambers which are cooled by the cooling liquid are switched to the heating circuit.
