Abstract

See full text

A cylinder head includes a cylinder head casting having a top deck and a bottom deck, and a coolant cavity. The cylinder head also includes an igniter column including an upper section, and a necked-down lower section extending upwardly from the bottom deck. The igniter column includes an inner surface forming an igniter bore such as for a sparkplug, and an outer heat-dissipation surface. The outer heat-dissipation surface is exposed in circumferential uniformity to the coolant cavity and extends radially inwardly of the inner surface at locations axially between an igniter seat and a bottom deck cavity surface. In some embodiments, a cylinder head includes an enclosed as-cast cooling channel axially between an igniter seat and a bottom deck combustion surface.
