AUTOMOBILE EXHAUST GAS RECIRCULATION SYSTEM

摘要

PURPOSE: An automobile exhaust gas recirculation system is provided to achieve improved combustion efficiency by effectively reducing the temperature of the combustion chamber. CONSTITUTION: A plurality of cooling pipes(5) are arranged in the lengthwise direction of a cooling reservoir(4) in such a manner that the exhaust gas is supplied from an exhaust manifold to an intake manifold at the state where the exhaust gas is cooled. An exhaust gas supply pipe(6) coupled to ends of the exhaust manifold and the intake manifold is arranged at both sides of the cooling reservoir. A coolant circulation pipe(7) is arranged at the upper and lower sides of the cooling reservoir. A distributor(8) having two or more distributor pipes(9) is connected between the coolant circulation pipe and the cooling reservoir in such a manner that the coolant quickly passes through the cooling reservoir, to thereby quickly cool the exhaust gas passing through the cooling pipes.
