Q

The lower section of a piston is called the __________.

🔍 Key Concepts

• Basic piston parts in an internal combustion engine (crown, ring lands, skirt) • How the piston moves inside the cylinder and which part helps guide and stabilize it • Difference between the top (combustion side) and the lower/side guiding surfaces of a piston

💭 Think About

• Which named part of a piston is closest to the combustion chamber, and which is furthest away from it? • Think about what part of the piston keeps it aligned and sliding smoothly in the cylinder bore — what is that area commonly called? • Match each option to a piston area: top, side, lower guiding surface, or something else.

✅ Before You Answer

• Be clear on which term refers to the top surface where combustion pressure acts. • Identify the term used for the side/lower area that runs in the cylinder and provides guidance. • Eliminate any option that is not a standard name for a piston section in marine diesel or gasoline engine terminology.
