Abstract: 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.
