Abstract: A preheating device for preheating the fuel of an internal combustion engine with a heating medium has a fuel transport device with a fuel inlet and a fuel outlet, and has a fuel transport channel connecting the fuel inlet and the fuel outlet. The preheating device also has a heating medium transport device with a heating medium inlet and a heating medium outlet, as well as a heating medium transport channel connecting the heating medium inlet and the heating medium outlet and/or at least one heating element. The fuel transport device and the heating medium transport device and/or the at least one heating element are in thermal contact with each other and thus form a heat exchanger via which a fuel transported in the fuel transport device can be heated by a heating medium transported in the heating medium transport device and/or by the at least one heating element.
