Abstract
A piston head is formed to have a bowl, micro chambers in the piston body adjacent to the bowl, and orifices providing communication between the micro chambers and the bowl. The micro chambers are formed in the piston head by using grooves that in part define the volume of the reaction chambers, and which are completely sealed from above with permanently secured plugs.
