Generally, where should you expect to find the greatest amount of wear on a cylinder liner?

Generally, where should you expect to find the greatest amount of wear on a cylinder liner?

🔍 Key Concepts

• Piston travel and ring position during the compression stroke and at top dead center (TDC) and bottom dead center (BDC) • Where gas pressure and temperature are highest inside the cylinder • How side thrust from the connecting rod affects liner wear near the top of the stroke

💭 Think About

• During which part of the stroke is the gas pressure and temperature against the liner wall the highest, and what does that do to wear? • Think about where the top compression ring stops and reverses direction: what happens to lubrication and metal contact at that point? • Which of the listed positions best matches the area where hot, high‑pressure gases most strongly press the top ring against the liner?

✅ Before You Answer

• Identify which option places the wear near the top ring travel area, not at the skirt or oil control ring location alone • Confirm that the location corresponds to high combustion pressure and temperature, not the coolest or most flooded-with-oil area • Check that the crank and stroke position described matches the end of the compression/combustion zone where ring reversal and gas loading are greatest

Question 1 of 27070

Generally, where should you expect to find the greatest amount of wear on a cylinder liner?

Adjacent to the piston skirt when the crank is on TDC.

Along the lower part of the liner wall opposite the oil control ring.

Opposite the top ring shortly after piston travel has ended the compression stroke.

Opposite the oil control ring when the crank is on bottom dead center.
