Which part of the piston is located above the top ring?

The piston lands are the areas of the piston that are located above the top ring and are crucial for the proper sealing and functioning of the engine. They serve as the surfaces that support the piston rings in their grooves and ensure that there is minimal leakage of combustion gases during the power stroke. The design of the piston lands directly affects the piston’s ability to maintain compression and withstand the forces exerted upon it during engine operation.

The piston skirt refers to the lower area of the piston that helps guide it within the cylinder. Although the skirt plays a vital role in maintaining alignment, it is not situated above the top ring. Piston ring grooves are the specific slots in the piston that hold the piston rings in place; however, these grooves are not found above the top ring itself. The connecting rod is a separate component that connects the piston to the crankshaft and facilitates the conversion of linear motion into rotational motion, and therefore does not relate directly to the area above the top ring.
