==LOW COMPRESSION NATURAL GAS ENGINE PISTON BOWL FOR IMPROVED COMBUSTION STABILITY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18511375 titled 'LOW COMPRESSION NATURAL GAS ENGINE PISTON BOWL FOR IMPROVED COMBUSTION STABILITY

==Simplified Explanation==

The abstract describes a piston with a contoured combustion bowl, including a swirl pocket with a specific reentrant angle.

* The piston has an annular body with a crown portion defining a longitudinal axis and a radial direction.
* In the crown portion, there is a radially outer squish surface and a swirl pocket with a reentrant surface extending axially downwardly and radially outwardly from the squish surface.
* The reentrant angle between the swirl pocket's reentrant surface and the squish surface ranges from 53.0 degrees to 57.0 degrees.

== Potential Applications ==

==Original Abstract Submitted==

A piston may have an annular body including a crown portion defining a longitudinal axis, a radial direction perpendicular to the longitudinal axis, a plane containing the longitudinal axis and the radial direction, and a contoured combustion bowl. In the plane containing the longitudinal axis and the radial direction, the crown portion includes a radially outer squish surface, and a swirl pocket having a reentrant surface that extends axially downwardly and radially outwardly from the squish surface defining a tangent that forms a reentrant angle with the squish surface that ranges from 53.0 degrees to 57.0 degrees.
