INTERNAL COMBUSTION ENGINE PROVIDED WITH A WATER-BASED OPERATING LIQUID FEEDING SYSTEM HAVING A HEATING DEVICE

An internal combustion engine (2) which comprises at least one cylinder provided with a combustion chamber, in which, following the combustion, exhaust gases (11) are generated; an exhaust duct (3), which is flown through by the exhaust gases (11); and a water-based operating liquid system (1) which includes a tank (4), which is designed to contain a quantity of water-based operating liquid, and a heating device (9), which is coupled to the tank (4) and is designed to heat the water-based operating liquid. In particular, the heating device (9) comprises a heating chamber (12), which surrounds a portion of the exhaust duct (3), comprises an inlet opening (13) designed to receive air from the outside, is configured to allow heat to be transferred from the walls of the exhaust duct (3) to the air received from the outside and comprises an outlet opening (14) for the heated air; and a heat exchanger (15), which receives the heated air and is thermally coupled to the tank (4) so as to release part of the heat owned by the heated air to the water-based operating liquid (10) contained in the tank (4).
