Methods and systems are provided for an EGR system including an EGR cooler module directly mounted to a cylinder head. In one example, the EGR cooler module includes an EGR inlet port, an EGR outlet port, a coolant inlet port, and a coolant outlet port all arranged parallel with each other and directly mounted to a first side of a cylinder head to interface with passages internal to the cylinder head. In another example, the EGR cool module includes an EGR inlet port and a coolant inlet port parallel to each other and directly mounted to a first side of a cylinder head to interface with passages internal to the cylinder head, while also including an EGR outlet port and a coolant outlet port to interface with passages external to the cylinder head.

Systems and method for an exhaust gas recirculation cooler coupled to a cylinder head

A cylinder head for an engine defines first and second exhaust runners fluidly coupled to an exhaust passage extending transversely in the head to an exhaust port on an exhaust side. The head defines an exhaust gas recirculation (EGR) passage connected to the exhaust passage and extending longitudinally to an EGR port on the exhaust side. The head also defines a cooling jacket passage adjacent to and substantially surrounding the EGR passage to cool EGR gases prior to cooling by an EGR cooler.
