Abstract
Official abstract text for this publication.
A combustion chamber for an opposed-piston engine has a rotationally skewed shape in a longitudinal section that is orthogonal to a chamber centerline, between diametrically-opposed openings of the combustion chamber through which fuel is injected. The rotationally skewed shape interacts with swirl to generate a tumble bulk charge air motion structure that increases turbulence.
First claim
Opening claim text (preview).
The invention claimed is: 1. A piston for an opposed-piston engine, comprising a flat end surface without a ridge, the flat end surface having an elongated, concave bowl formed therein to define a combustion chamber with an elongated bowl formed in a flat end surface of an opposing piston; the flat end surface meeting a piston sidewall at a peripheral edge having a circular shape that is centered on a longitudinal axis of the piston and that is disposed at a single longitudinal lev…
