An internal combustion engine having an exhaust duct through which pass exhaust gases; and a water-based operating liquid system which includes a tank, and a heating device, which is coupled to the tank and is designed to heat water-based operating liquid. The heating device includes a heating chamber having an inlet opening designed to receive ambient air and that allows heat to be transferred from the walls of the exhaust duct to the air received from the environment and comprises an outlet opening for the heated air; and a heat exchanger, which receives the heated air and is thermally coupled to the tank so as to release part of the heat of the heated air to the water-based operating liquid contained in the tank.

Internal combustion engine provided with a water-based operating liquid feeding system having a heating device

Injection method and system for the injection of water in an internal combustion engine; the following steps are substantially comprised: operating, when the internal combustion engine is turned on, a reversible pump in order to suck water from a tank and feed the water under pressure to an injector through a feeding duct; cyclically opening, when the internal combustion engine is turned on, the injector in order to inject the water towards at least one cylinder of the internal combustion engine; and draining the water, when the internal combustion engine is turned off, from the injector and the feeding duct by using a release valve connecting the feeding duct to the outside.

Injection method and system for the injection of water in an internal combustion engine

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.

System to feed water to at least one combustion chamber in an internal combustion engine

A device for the acquisition and conditioning of a sound signal generated by a source of an internal combustion engine and comprising a box-shaped support body having a first measuring assembly and a second measuring assembly; wherein the first measuring assembly is provided with at least two first microphones which lie on a first plane and are configured for the detection of a first acoustic signal generated by the source along a first provenance direction; and wherein the second measuring assembly is provided with at least a second microphone arranged on a second plane configured for the detection of a second acoustic signal generated by the source along a second provenance direction different from the first provenance direction.
