Title:
INTERNAL COMBUSTION ENGINE PROVIDED WITH SYSTEM SUPPLYING WATER-BASED OPERATOR LIQUID
Document Type and Number:
Japanese Patent JP2020070806
Kind Code:
A
Abstract:
To provide an internal combustion engine provided with a system supplying a water-based operator liquid.SOLUTION: An internal combustion engine comprises: a cylinder defining a combustion chamber in which exhaust gases are generated following the combustion; an exhaust duct, through which the exhaust gases flow; and a system supplying a water-based operator liquid to the combustion chamber comprising a tank, which is designed to contain a certain amount of water-based operator liquid, and a heating device, which is designed to heat the water-based operator liquid contained in the tank. The heating device comprises: a first gas-liquid heat exchanger, which is designed such that at least part of the exhaust gases flowing along the exhaust duct pass therethrough; 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.SELECTED DRAWING: Figure 2
