ABSTRACT:
A cylinder head, more preferably a piston, of an internal combustion engine is provided on its compression face with a substantially central bowl and an annular common squish jet pocket encircling and spaced radially from the bowl to define an annular lip separating the squish pocket from the bowl. A plurality of discrete squish jet channels are formed through the lip and connect the squish pocket with the bowl at locations circumferentially spaced about the bowl. Each of the channels is open to the compression face along its full length from an inlet end connected to the annular squish jet pocket to a discharge end opening into the bowl. The channels provide the main paths for fluid flow from the area on the compression face surrounding the bowl into the bowl and in particular from the annular pocket into the bowl. The piston and cylinder are so shaped that as the piston approaches a top dead center position gases are forced from the compression face and pocket into and along the channels from the inlet end to the discharge end and are discharged into the bowl and increase the turbulence in the gases (air fuel mixture) in the bowl.
