SYSTEMS AND METHODS FOR AN EXHAUST GAS RECIRCULATION VALVE CARTRIDGE IN AN INTEGRATED EXHAUST MANIFOLD CYLINDER HEAD
DRIVE
December 3, 2020
Systems and methods are provided for an exhaust gas recirculation (EGR) system in a vehicle. In one example, a system may include a cylinder head including an integrated exhaust manifold (IEM), an EGR cartridge including an EGR valve positioned in the cylinder head at a central collector region of the IEM, and a water jacket formed within the cylinder head, the water jacket including at least one cooling passage that extends around a circumference of the EGR cartridge. In this way, an EGR system is provided that has a reduced volume between an exhaust valve of a cylinder to the EGR valve, reducing packaging space and complexity of the EGR system while increasing engine performance.
