compression and oil control rings
Explanation:
There are two types of piston rings
1. Compression Rings
2. Oil Control Rings
Answer is:
crown of the piston
Explanation:
The top portion of the piston is called as a piston crown.
In an engine, the temperature of the piston will be more at the crown of the piston. The piston crown is subject to the high temperatures in the combustion space and the surface is liable to be eroded/burnt away. For this reason, the material from which the crown is made must be able to maintain its strength and resist corrosion at high temperatures.
