An exhaust gas recirculation system comprises an exhaust gas cooler ( 1 ) downstream of which a condenser ( 2 ) is disposed through which flows fresh air ( 7 ).
Opening claim text (preview).
The invention claimed is: 1. An exhaust gas recirculation system comprising an exhaust gas cooler and a condenser positioned downstream from the exhaust gas cooler, wherein the exhaust gas cooler includes a plurality of separated pipes through which exhaust gas passes and an exhaust gas collector for collecting an exhaust gas passing through the plurality of separated pipes, and wherein the condenser is formed inside the exhaust gas collector for removing moisture contained in the exhaust gas collector; wherein the condenser is formed as a fresh air tube extending through the exhaust gas collector, and includes an outlet in communication with a tank; and wherein the outlet of the condenser is discharging condensed water formed by condensing the moisture contained in the exhaust gas inside the exhaust gas collector to the tank; wherein the condenser is formed inside the exhaust gas collector for removing moisture contained in the exhaust gas collector; wherein the condenser is formed as a fresh air tube extending through the exhaust gas collector, and includes an outlet in communication with a tank; and wherein the outlet of the condenser is discharging condensed water formed by condensing the moisture contained in the exhaust gas inside the exhaust gas collector to the tank. 2. The exhaust gas recirculation system with the exhaust gas cooler according to claim 1 , wherein a tube axis of the fresh air tube extends substantially perpendicularly to a direction of flow of the exhaust gas. 3. The exhaust gas recirculation system with the exhaust gas cooler according to claim 1 , wherein the fresh air tube comprises ribs. 4. An exhaust gas recirculation system comprising an exhaust gas cooler, and a condenser positioned downstream from the exhaust gas cooler, and an exhaust gas collector for collecting an exhaust gas passing through the exhaust gas cooler; wherein the condenser includes an outlet leading to a tank, wherein the tank is connected to a combustion chamber and to an exhaust gas outlet of a combustion engine, wherein the condensate condensed by the condenser is collected in the tank through the outlet, and the condensate collected in the tank is guided to the combustion chamber, the exhaust gas outlet of the combustion engine, or both the combustion chamber and the exhaust as outlet; and wherein the condenser is formed inside the exhaust gas collector for removing moisture contained in the exhaust gas collector; wherein the condenser is formed as fresh air tube extending through the exhaust gas collector, and includes an outlet in communication with a tank; and wherein the outlet of the condenser is discharging condensed water formed by condensing the moisture contained in the exhaust gas inside the exhaust gas collector the tank.
