A piston device with combined vertical and lateral gas port is provided. The device comprises an engine piston with integrated combined gas ports to optimize performance, sealing, and durability. Central to the invention is a singular gas port that merges lateral and vertical gas port functionalities, directing pressurized combustion gases to enhance the piston top ring's seal within the cylinder bore, thus reducing blow-by and increasing efficiency. The device also includes features such as valve pocket reliefs, structural lands, and grooves to support piston rings and maintain proper positioning, alongside a strengthened skirt and strut assembly for durability. A self-cleaning combined gas port structure improves resistance to clogging and enhances gas flow dynamics, particularly in high-performance settings. Embodiments further include variations in port configurations and a potential two-ring design, offering versatility while maintaining structural and functional benefits.

A piston for an internal combustion engine comprising a piston body having a crown adjacent a skirt. Any of an outer crown surface of the crown, piston ring grooves in the crown, and/or the crown include a steel H11 alloy and/or a steel H13 alloy. The steel H11 or H13 material is applied in any technique such as a piston crown coating/cladding, fused overlay, powder cladding, welded on an outer crown surface of the crown, and/or included in the crown and/or skirt of a monolithic piston. The steel H11 or H13 material is applied with an additive manufacturing item, applied with a coating, buttering, or other surface modification to facilitate joining to the piston body. The application of the steel H11 or H13 material with a heat treatment to at least the piston crown creates an elevated temperature oxidation resistant high performance piston.
