A preheating device for diesel internal combustion engines is characterised by a tube bundle running from the engine block to the fuel tank and designed as a heat exchanger, in which at least one fuel feed line leading from the fuel tank to the injection pump and one feed line, leading from the coolant reservoir in the engine block to the fuel tank, for a preheating liquid heated by the combustion of the fuel in the combustion cylinder are brought together. <IMAGE>
