Abstract
A sparkplug cooling passageway is disposed in a second body portion of the cooled pre-combustion chamber assembly. The sparkplug cooling passageway has a first side surface spaced about a threaded bore portion disposed in the second body portion. The first side surface and a second side surface define the sides of the sparkplug cooling passageway. An opening disposed in the second body portion opens into the passageway at the second side surface and passes cooling fluid between a cylinder head and the passageway.
