Internal combustion engine having: a cylinder defining a combustion chamber; an exhaust duct that is flown through by the exhaust gases; and a system to supply a water-based operator liquid to the combustion chamber having: a tank designed to contain a certain amount of water-based operator liquid and a heating device designed to heat the water-based operator liquid contained in the tank. The heating device has: a first gas-liquid heat exchanger, which is designed to be flown through by at least part of the exhaust gases flowing along the exhaust duct; a second liquid-liquid heat exchanger, which is designed to heat the water-based operator liquid contained in the tank; and a hydraulic circuit, which is designed to send round an exchange fluid through the first heat exchanger to transfer the heat from the exhaust gases to the exchange fluid and through the second heat exchanger to transfer the heat from the exchange fluid to the water-based operator liquid contained in the tank.

Internal combustion engine provided with a system supplying a water-based operator liquid

A system for feeding water to at least one combustion chamber in an internal combustion engine having: a tank designed to contain a quantity of water; a feeding duct; a pump designed to draw water from the tank and to pump pressurised water into the feeding duct; and at least one silver-containing body which is contained in the tank in contact with the water.
