Abstract: A cylinder head defines an EGR crossover tube integrally formed in the cylinder head. The EGR crossover tube includes a first end fluidly coupled to an exhaust port of an engine. A second end is fluidly coupled to an intake port of the engine. A Venturi tube configuration is positioned between the first and second ends. A first sensor port extends through the cylinder head to the EGR crossover tube. The first sensor port is positioned at a restriction of the Venturi tube configuration. A second sensor port extends through the cylinder head to the EGR crossover tube. The second sensor port is positioned proximate the first end. A differential pressure sensor includes a first pressure sensor positioned in the first sensor port and a second pressure sensor positioned in the second sensor port.
