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

摘要： The internal combustion engines (M) of the invention are provided with a cooling water circuit, associated with a water radiator and with a lubricant oil circuit. The heat exchanger (HE) comprises an inlet and an outlet of water connected, in series, to an outlet of the water radiator, by means of a cooled water conduit and of the cooling water circuit, and to an inlet of the water radiator, by means of a return conduit and a hot water conduit; a fuel inlet nozzle and a fuel outlet nozzle, selectively connected to the fuel supply to the engine (M); and an inlet and an outlet of lubricant oil, connected to the lubricant oil circuit by means of respective oil conduits.
