APPARATUS FOR HEATING FUEL INJECTED INTO A DIESEL ENGINE ABSTRACT OF THE DISCLOSURE. The object is to provide an apparatus for easily starting up the engine under cold conditions and avoid any crystallisation of the Diesel oil under these conditions. The apparatus comprises a heat exchanger (2) heating the fuel by means of a heat- carrying fluid, such as the cooling liquid of the engine, when it has reached a predetermined minimum value. A reserve supply of hot fuel (1) is con- nected to the exchanger (2) and comprises at least one auxiliary source of heat (20). The reserve supply of hot fuel is connected to an injection pump (8) and also to a thermostat valve (11) inserted in a return pipe (10) of the injection pump (8). This valve (11) connects the return valve (10) directly to the reserve supply of hot fuel (1) below a previously fixed temperature of the latter or when the tempe- rature of the fuel is higher than the previously fixed temperature, it connects the return pipe (10) to the main fuel tank (13) which is itself connected to the heat exchanger.
