Ecological/fuel optimization device for internal combustion engines which increases a moist air mass entering said engine by means of vacuum suction or normal aspiration

An ecological/fuel optimization device for internal combustion engines which increases a mass of moist air entering said engine by means of vacuum suction or normal aspiration, wherein said device comprises a container (1) which exhibits two compartments: - a compartment A including on its top portion a room air inlet (4) and an outlet for a mass of moist air (6), said room air inlet being connected to the central top portion of a buoy (3) by means of a flexible pipe (5), said buoy (3) including an air passage orifice (11), which carries the air that enters through said flexible pipe (5) towards a fluid column placed under said buoy (3); and a counterweight (7), said compartment A also including guide means (2) along which said buoy (3) moves, and a closing element (9) arranged on the central bottom portion of said compartment A; and - a compartment B surrounding said compartment A, in fluid communication with the later by its bottom, the height of said compartment B being equal to the height difference between said compartment A and said buoy (3), such that the fluid column height coincides with the bottom portion of said buoy (3), said compartment B further including on its top portion a fluid refilling plug (8) and a pressure compensating orifice (8') which is also in fluid communication with the compartment A at the buoy (3) bottom level.
