Abstract:
An intake duct cast as a recess in a combustion engine cylinder head that opens into a combustion chamber thereof at its lower end via an annular valve-seat housing. The intake duct, over part of its length, includes a substantially planar underside connected to the housing via a transition region that defines a shrinkage void of rounded shape within the mass of the cylinder head.
