Abstract
The present disclosure provides an open-faced piston with a circumferential groove into which a piston ring assembly is arranged. Openings at the bottom of the circumferential groove and between a front land of the open-faced piston and the piston face are provided. The openings are arranged to allow for a combustion reaction to propagate through the volume defined between the bottom of the piston ring assembly and the piston face such that at least a portion of an air and fuel mixture located in that volume is reacted.
Claims25
A piston comprising:
- a circumferential groove that accommodates a piston ring assembly,
- wherein a majority of a side of the circumferential groove is open to a face of the piston.
