Abstract
Official abstract text for this publication.
A piston for reduced production of particulate matter during combustion of a fuel directly injected after a top dead center position includes a piston body defining a piston body diameter of about 263 mm, and a combustion face upon the first axial body end. The combustion face includes a combustion bowl, and an annular piston rim extending circumferentially around the combustion bowl. Inner and outer rim surfaces together comprise a horizontal width of the rim in a ratio of about 1:1 to about 2:1. The inner rim surface includes a chamfer sloping from about 9° to about 11°, such that a profile of the rim is relieved to limit deflection by the piston of the directly injected fuel toward a cylinder wall.
First claim
Opening claim text (preview).
What is claimed is: 1. A piston, for reduced production of particulate matter during combustion of a fuel directly injected after a top dead center position of the piston in an engine cycle into a cylinder bore about 265 mm in diameter in a compression ignition internal combustion engine, the piston comprising: a piston body defining a longitudinal axis extending between a first axial body end and a second axial body end, and including an outer body surface extending between the f…
