    摘要： The heat exchanger (HE) has a first stage and a second stage (E1, E2) which are seated and affixed in a connecting block seated and affixed to the engine (M). The first stage (E1) is provided with a fuel inlet nozzle and a fuel outlet nozzle which are connected to the supply of fuel to the engine (M), and the connecting block defines: a return conduit, communicating an outlet of a cooling water circuit of the engine (M) with a water inlet in the first stage (E1); an interconnecting conduit communicating a water outlet of the first stage (E1) with a water inlet of the second stage (E2); an outlet conduit communicating a water outlet of the second stage (E2) with an inlet of a water radiator having an outlet; and two oil conduits, communicating a lubricant oil circuit of the engine (M) with the second stage (E2).

    摘要： The system is applied to an engine (M) having an injection system (10), a fuel feed line (30) and a cooling system (CS), by means of a cooling fluid which circulates, through hot fluid ducts (61a, 61b) and cold fluid ducts (62a, 62b), through the engine (M) and through a heat exchanger (60). The feed line (30) comprises: a first segment (31), connected to the injection system (10) and provided with a first valve (33), to be closed when the fuel temperature is below a maximum value, and open when the fuel temperature reaches the maximum value; and a second segment (32) derived from the first and absorbing thermal energy from the hot fluid duct (61a, 61b) or from the combustion gases and provided with a second valve (34) which remains open while the fuel temperature is lower than the maximum value, and which is closed when said temperature reaches the maximum value.
