Abstract
An exhaust gas recirculation system having an exhaust line connected to an exhaust manifold of an engine; an intake line connected to an intake manifold of the engine; and an EGR line that intercommunicates the exhaust line and the intake line, in which a part of exhaust gas exhausted from the exhaust line is delivered to the intake line via the EGR line to be recirculated in the engine, is provided with a liquid cooling heat exchanger made of a corrosion-resistant material at downstream of an intersection with the EGR line in the intake line.
Claims12
An exhaust gas recirculation system, comprising:
- an exhaust line connected to an exhaust manifold of an engine;
- an intake line connected to an intake manifold of the engine;
- and
