Piston device with combined vertical and lateral gas port

A piston device with combined vertical and lateral gas port comprising:

• an internal combustion engine piston comprised of:
• a piston crown defining a vertical gas port, the vertical gas port being configured to direct a pressurized gas downward;
• a top land defining a lateral gas port;
• a combined gas port formed as a continuous opening through the top land, the combined gas port formed by the vertical gas port and the lateral gas port;
• wherein the combined gas port combines the functional attributes of a lateral gas port and a vertical gas port, the combined gas port being positioned to direct a pressurized combustion gas to enhance a sealing performance of a piston top ring;
• wherein the combined gas port is self-cleaning;
• wherein the lateral gas port is comprised of a rounded gas port end;
• and
• further wherein the gas port end extends beyond a tangency with a floor of a top ring groove.
