<p>In order to be purified, the exhaust gases of a combustion engine are cooled down to a low temperature level, so that the condensable fractions thereof are condensed. The gases are passed through the condensate previously obtained and collected. Noxious substances such as soot, tar and the like are diluted in the condensate up to a limit value, the better the more noxious substances were previously diluted in the condensate. The condensate enriched with noxious substances is evacuated in a quantity which is the same as the quantity of newly formed condensate, e.g. into the communal sewage system, if necessary after the addition of neutralizing agents. </p> |
