    (54) Device for the combustion improvement of endothermic engines


    (57) According to the invention a device has the task of recovering and enriching the partially burnt fumes of endothermic engines, so as to make them suited to undergo further combustion.
    The device comprises a tank (2) containing an enriching fuel, a tank (16) containing air under pressure and ducts (15, 21, 22) for connecting the tank (2) containing the enriching fuel both with the tank (16) containing air under pressure, and with the fuel and exhaust manifolds.
    The partially burnt fumes recovered from the exhaust manifold are mixed with the enriching fuel through a mixing valve (37) and then they are sent back to the combustion chamber for a re-­combustion, which in this case will be practically complete.
