Engine assembly with valve seat vent passages and method of forming










Image Number 4 for United States Patent #8127735.

An engine assembly may include an engine block defining a cylinder bore, a cylinder head fixed to the engine block, and a valve seat insert. The cylinder head may include an intake port, defining an inlet in fluid communication with an air source and an outlet in fluid communication with the cylinder bore. The valve seat may be defined at the outlet of the intake port and may include a stepped region. The stepped region may define a seating surface extending radially outward from the intake port. The seating surface may include a series of protrusions circumferentially spaced from one another around the outlet and forming a series of recesses therebetween. The valve seat insert may be located within the stepped region and may include a first axial end surface abutting the protrusions on the seating surface.
