Abstract
Abstract The combustion chamber of an internal-combustion engine is fed via a dispersion supply conduit with a dispersion of water and of fuel supplied via a fuel supply conduit and is fed via an air supply conduit with the air required for the combustion. The exhaust gases generated within the combustion chamber during the combustion are passed via an exhaust gas conduit into a heat exchanger being in connection with a condensate collecting chamber for receiving the condensate formed on cooling the hot exhaust gases and vapors. This condensate is utilized for the production of the fuel-water-dispersion. The heat of condensation being at disposal within the heat exchanger is utilized for heating the dispersion-air-mixture supplied into the combustion chamber of the internal-combustion engine or for heating the air required for the combustion.
