  • Exhaust gas recirculation system module with integral vacuum
    Patent number: 7814893
    Abstract: A system module is provided for recirculating exhaust gases from an internal combustion engine to an intake manifold of the internal combustion engine. The module includes a body (12) including a passageway (41) between an exhaust gas inlet (32) and an exhaust gas outlet (34). An orifice (36) constricts the flow of exhaust gases proximate the exhaust gas outlet. A differential pressure sensor (38) is constructed and arranged to sense differential pressure across the orifice. A manifold absolute pressure sensor (42) is constructed and arranged to sense vacuum pressure associated with the exhaust gas outlet. A first hose (40) is coupled with the body and provides the differential pressure sensor with vacuum pressure on a first side of the orifice. A second hose (44) is coupled with the body and provides the manifold pressure sensor with vacuum pressure. The first and second hoses are integral with the system module.
