1. Piston: The main component of the assembly, the piston moves up and down within the cylinder, transferring force from the expanding gases to the crankshaft.
2. Piston Rings: These are metal rings that fit around the piston and help seal the combustion chamber, preventing gas leakage and reducing oil consumption.
3. Piston Pin (Wrist Pin): This is a metal pin that connects the piston to the connecting rod, allowing the piston to move up and down while maintaining alignment with the connecting rod.
4. Connecting Rod: This rod connects the piston to the crankshaft, transferring the linear motion of the piston into rotational motion of the crankshaft.
5. Piston Skirt: The lower part of the piston that helps guide the piston within the cylinder and provides stability during operation.
6. Piston Crown: The top surface of the piston that is exposed to the high temperatures and pressures of combustion.
7. Piston Cooling Gallery: Some pistons may have cooling galleries or channels to help dissipate heat and prevent overheating.
8. Piston Pin Retainers: These are clips or rings that secure the piston pin in place within the piston and connecting rod.

Crown
- The crown is the top portion of the piston that is exposed to the combustion gases. It is typically flat or slightly domed, and it has a number of features that help to promote combustion and reduce knock.
Ring lands
- The ring lands are the grooves that are machined into the piston to hold the piston rings. There are typically three ring lands, one for each of the three piston rings.
Ring grooves
- The ring grooves are the small channels that are machined into the ring lands to hold the piston rings in place. The ring grooves are typically tapered, so that the piston rings can expand and contract as they heat up and cool down.
Gudgeon pin hole
- The gudgeon pin hole is the hole that is drilled through the piston to accommodate the gudgeon pin. The gudgeon pin is a small, cylindrical rod that connects the piston to the connecting rod.
Connecting rod seat
- The connecting rod seat is the surface on the piston that is machined to mate with the connecting rod. The connecting rod seat is typically tapered, so that the connecting rod can be easily assembled and disassembled.
Wrist pin clips
- The wrist pin clips are small, C-shaped clips that are used to secure the gudgeon pin in place. The wrist pin clips are typically made from spring steel, and they are designed to prevent the gudgeon pin from falling out of the piston.
Piston skirt
- The piston skirt is the lower portion of the piston that extends below the ring lands. The piston skirt helps to guide the piston as it moves up and down the cylinder bore. The piston skirt is typically coated with a low-friction material, such as graphite, to reduce wear and tear.
