🔍 Key Concepts

• Piston seizure and what physically happens when metal parts overheat and expand • The role of cooling systems (for cylinder walls and pistons) in a diesel engine • The importance of lubrication between piston and liner

💭 Think About

• Think about what conditions would cause the piston to expand so much that it can no longer move freely inside the cylinder liner. • Ask yourself: if the engine runs hot, which parts (cylinder walls, piston, or both) are affected, and how does that change the clearance between them? • Consider what happens to metal surfaces sliding against each other if the oil film is too thin or missing.

✅ Before You Answer

• Verify which options would increase friction and temperature between the piston and liner. • Check which conditions would reduce the oil film or cause uneven expansion between piston and cylinder. • Before choosing, ask: could more than one of these problems realistically lead to a piston seizing in the bore?
