PISTON, BLOCK ASSEMBLY, AND METHOD FOR COOLING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240011451 titled 'PISTON, BLOCK ASSEMBLY, AND METHOD FOR COOLING

Simplified Explanation

The abstract of the patent application describes a piston design that includes a skirt, a crown, and a cooling gallery. The skirt has an upper body portion, and the crown is formed at the upper body portion. A wall is formed underneath the crown to define a cooling gallery within the piston. The cooling gallery consists of a peripheral portion and a central portion, and it is designed to receive and retain cooling fluid. The movement of the cooling fluid within the cooling gallery helps in cooling both the outer region and the center region of the piston as it travels between top dead center and bottom dead center.

  • The patent application describes a piston design with a cooling gallery.
  • The cooling gallery is formed by a wall underneath the crown of the piston.
  • The cooling gallery has a peripheral portion and a central portion.
  • The cooling gallery is configured to receive and retain cooling fluid.
  • The movement of the cooling fluid within the cooling gallery helps in cooling the piston.

Potential Applications:

  • Automotive industry - This piston design can be used in internal combustion engines to improve cooling and performance.
  • Aerospace industry - The cooling gallery can be beneficial for pistons used in aircraft engines to enhance cooling and efficiency.

Problems Solved:

  • Overheating - The cooling gallery helps in dissipating heat from both the outer and center regions of the piston, preventing overheating.
  • Performance degradation - By effectively cooling the piston, this design can prevent performance degradation caused by excessive heat.

Benefits:

  • Improved cooling - The cooling gallery design allows for better cooling of the piston, enhancing overall engine performance.
  • Increased durability - By preventing overheating, the piston is less likely to suffer from wear and tear, leading to increased durability.
  • Enhanced efficiency - The cooling of the piston helps in maintaining optimal operating conditions, leading to improved fuel efficiency.


Original Abstract Submitted

a piston can include a skirt, a crown, and a cooling gallery. the skirt can have an upper body portion. the crown can be formed at the upper body portion. a wall can be formed underneath the crown so as to define a cooling gallery within the piston. the cooling gallery includes cooling gallery peripheral portion and a cooling gallery central portion. the cooling gallery can be configured to receive and to retain an amount of cooling fluid and to cause movement thereof within the cooling gallery between a cooling gallery peripheral portion and a cooling gallery central portion as the piston travels between top dead center and bottom dead center so as to cool both the piston outer region and the piston center region.
