Abstract: An engine cylinder head in which a water jacket and an EGR passage are formed therein, the EGR passage opening into an exhaust passage at one end and opening into a side of an intake side at the other end thereof, the engine cylinder being characterized in that the EGR passage is provided outwardly in a cylinder arrangement direction of head bolt pass-through holes formed in one end of the engine cylinder head in the cylinder arrangement direction. Thus, because the EGR passage can be made much longer, the cooling capacity for re-circulating gas can be improved. Moreover, because the EGR passage can be provided without head bolts being spaced apart from the combustion chamber, the surface pressure around combustion chambers in the cylinder head relative to a cylinder block can be prevented from being lowered.
