ABSTRACT:
A heating device for pre-heating liquid fuel, especially diesel fuel and for heating devices of a low heating performance which are independent from a motor having a heating performance which is suitable for mounting into vehicles, which are driven by the liquid fuel. The pre-heating is effected by a transmission of heat of the exhaust gas to the fuel of the heating device, the fuel being lead through a continuous tubular wrapping in one layer or through a hollow cylinder formed or positioned around the exhaust pipe. This wrapping or hollow cylinder is part of the fuel main from the fuel tank to the fuel supply pump of the heating device. A pre-heating of the content of the tank is effected by the return of the pre-heated, but not burnt fuel through a fuel return main back into the tank. A heat transmitting jacket is advantageously disposed between the wrapping, or a hollow cylinder and the exhaust gas pipe.
