  • Valve seat insert
    Patent number: 6260531
    Abstract: A valve seat insert 10 for use in combination with a cylinder head 12. Insert 10 is disposed within a cavity 24 formed within cylinder head 12 and includes several notches 40 which cooperate with surface 26 within cavity 24 to form a plurality of passages or channels 50 which allow fuel 18 to freely pass between surface 26 and insert 10. Channels 50 are effective to substantially prevent fuel 18 from becoming trapped between insert 10 and cylinder head 12, thereby preventing the formation of corrosive acids and byproducts.
