Systems and methods for an exhaust gas recirculation valve cartridge in an integrated exhaust manifold cylinder head

A system, comprising:

• an engine including a cylinder head, the cylinder head including an integrated exhaust manifold (IEM) and a water jacket contained therein, the water jacket including an upper jacket and a lower jacket fluidically coupled via drill passages;
• and
• an exhaust gas recirculation (EGR) system including an EGR cartridge coupled within a cylindrical bore in the cylinder head, the EGR cartridge positioned to receive engine exhaust gas directly from the IEM, and an EGR passage integrated in the cylinder head, the EGR passage fluidically coupling the EGR cartridge to a cooler positioned external to the engine.

A method, comprising:

• flowing coolant around an exhaust gas recirculation (EGR) valve coupled in a cylinder head of an engine via a water jacket of the cylinder head, the EGR valve positioned to receive exhaust gas directly from an exhaust manifold integrated in the cylinder head;
• and
• adjusting a position of the EGR valve based on a desired EGR rate, wherein flowing coolant around the EGR valve includes flowing coolant through the water jacket at a flow rate of at least one meter per second.
