The piston is a component inside an engine that is connected to the crankshaft and moves up and down in the cylinder. It has compression rings and an oil ring assembly to seal the cylinder and distribute oil. The connecting rod connects the piston to the crankshaft to transfer the linear motion of the piston into rotational motion. Ring grooves house the piston rings as the piston moves through its four stroke cycle of intake, compression, combustion, and exhaust.

3. First compression ring
Second compression ring
The compression ring is the steel metal
nearest to the working place of the
piston.

4. Oil ring Assembly
Oil ring assembly a piston ring designed
to secure proper distribution of
lubricating oil over the length of cylinder
wall traversed by the piston

5. Connecting rod
The connecting rod is connected to the
crankshaft that moves the piston back
and forth.

6. Ring grooves
 The ring grooves is the channel which
the piston rings reside.
