Which of the following problems may occur if the clearance between a piston and cylinder liner is insufficient?

Question 1 of 27070

Which of the following problems may occur if the clearance between a piston and cylinder liner is insufficient?

🔍 Key Concepts

• Relationship between piston-to-liner clearance and lubrication film thickness • What happens when metal parts in relative motion have too little clearance and contact each other • Typical symptoms of overheating and metal-to-metal contact in engines

💭 Think About

• Think about how the oil film behaves if the space between piston and liner is very small—can a proper film form and stay there? • If the piston expands as it heats up, what happens in a space that was already very tight when cold? • When metal surfaces run with inadequate clearance, what kinds of damage or failures can develop over time or suddenly?

✅ Before You Answer

• Compare each option with what metal-to-metal contact would realistically cause inside the cylinder • Ask whether each listed problem is mutually exclusive or could they all occur from the same basic cause • Verify in your engine theory notes how insufficient clearance is described and what multiple effects are commonly mentioned together
