A four-valve per cylinder engine has two intake valves, two exhaust valves and a centrally located fuel injector. Between each adjacent pair of valves is a valve bridge with a point of minimum separation between adjacent valves. In the present disclosure, the glow plug port is defined in the cylinder top at a location outboard of the minimum separation between adjacent and at a depth which is tangent to an edge of a fuel jet emanating the injector. By placing the glow plug farther outboard than found in the prior art, the glow plug contacts the fuel as it comes out of the injector and as it rebounds off a feature of the piston bowl.

A valve seat insert,for use in combination with a cylinder head,. Insert,is disposed within a cavity,formed within cylinder head,and includes several notches,which cooperate with surface,within cavity,to form a plurality of passages or channels,which allow fuel,to freely pass between surface,and insert,. Channels,are effective to substantially prevent fuel,from becoming trapped between insert,and cylinder head,, thereby preventing the formation of corrosive acids and byproducts.
