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
This piston design could be used in internal combustion engines to improve fuel efficiency and combustion efficiency.
Problems Solved
This technology helps enhance the mixing of air and fuel in the combustion chamber, leading to more complete combustion and reduced emissions.
Benefits
- Improved fuel efficiency - Enhanced combustion efficiency - Reduced emissions
Potential Commercial Applications
Optimizing engine performance in automotive, marine, and industrial 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.
