ABSTRACT:
An exhaust gas recirculation system. A water jacket in a cylinder block is configured for coolant to flow therein. A cylinder head is attached to the cylinder block. A cylinder is disposed in the cylinder block and the cylinder head. An intake manifold runner is connected to an intake hole of the cylinder. An exhaust manifold runner is connected to an exhaust hole of the cylinder. A first recirculation gas pathway is disposed in the cylinder block, and receives recirculated exhaust gas from the exhaust manifold runner. A second recirculation gas pathway is disposed in the cylinder head, and has a first end connected to the first recirculation gas pathway and a second end connected to the intake manifold runner. A recirculation valve, mounted at the second recirculation gas pathway, controls supply of the recirculated exhaust gas to the intake manifold runner. An engine control unit controls the recirculation valve.
