LASER HARDENING OF CYLINDER BORE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18170796 titled 'LASER HARDENING OF CYLINDER BORE

The system described in the patent application involves using a laser head and a controller to heat treat cylinder bores within an engine by creating hardened pills in various positional zones.

• Laser head and controller used for heat treating cylinder bores
• Creation of hardened pills in positional zones within each cylinder bore
• Process involves moving the laser head to each cylinder bore multiple times
• First and second plurality of hardened pills created in different positional zones

Potential Applications: - Automotive industry for engine manufacturing - Industrial machinery with cylinder components - Aerospace industry for specialized engines

Problems Solved: - Enhancing the durability and performance of cylinder bores - Improving the overall efficiency of engines - Reducing wear and tear on cylinder components

Benefits: - Increased longevity of engine components - Enhanced engine performance and reliability - Cost-effective solution for heat treating cylinder bores

Commercial Applications: Title: Advanced Heat Treatment System for Engine Cylinder Bores This technology can be utilized in the automotive, industrial, and aerospace sectors for manufacturing and maintenance of engines. It has the potential to improve engine efficiency and longevity, making it a valuable asset in various industries.

Questions about the technology: 1. How does the laser head move to each cylinder bore to create hardened pills? 2. What are the specific benefits of creating hardened pills in different positional zones within the cylinder bores?

Original Abstract Submitted

A system for heat treating cylinder bores within an engine includes a laser head and a controller adapted to cause the laser head to move to each cylinder bore and create a first plurality of hardened pills within each one of a first plurality of positional zones, cause the laser head to move to each cylinder bore and create a second plurality of hardened pills within each one of the first plurality of positional zones, cause the laser head to move to each cylinder bore and create a first plurality of hardened pills within each one of a second plurality of positional zones, cause the laser head to move to each cylinder bore and create a second plurality of hardened pills within each one of the second plurality of positional zones.
