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.

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 heat exchanger comprises a first and a second stage (E1,E2), each having an inlet and an outlet of water, the second stage (E2) having an inlet and an outlet of oil, the first stage (E1) being provided with fuel inlet and outlet nozzles, selectively connected, in parallel, to the fuel supply to the engine (M). The inlet and outlet of water of the first stage (E1) are respectively connected to the outlet of the water radiator, by means of a cooling water circuit internal to the engine (M), and to the water inlet of the second stage (E2). The water outlet of the second stage (E2) is connected to the inlet of a water radiator, and the inlet and outlet of oil in the second stage (E2) are connected in series to a lubricant oil circuit internal to the engine (M).

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).
