The most severe cavitation erosion occurring...

🔍 Key Concepts

• Cavitation and how collapsing vapor bubbles can damage metal surfaces • The motion of the piston and which parts of the liner see the most rapid pressure/velocity changes in the coolant on the waterside • The difference between thrust side and anti-thrust side of a cylinder liner in a diesel engine

💭 Think About

• At what piston positions does the liner experience the greatest vibration and rapid pressure fluctuations against the coolant on the waterside? • Is cavitation erosion usually concentrated in one band/zone or spread evenly over a large area of the liner? • How does the thrust side loading (from the connecting rod angle) affect liner vibration and cavitation compared with the non‑thrust side?

✅ Before You Answer

• Identify where along the stroke (upper, lower, or mid‑stroke) the liner wall flexing and vibration is typically greatest in medium/high‑speed diesels • Confirm whether cavitation erosion normally appears as a narrow belt or band rather than over the whole upper or lower half • Make sure you know which side of the liner is the thrust side (the side the piston is pushed against on the power stroke) before choosing among the options

The most severe cavitation erosion occurring on the waterside of diesel engine wet cylinder liners normally occurs __________.

throughout the lower one-half of the liner

throughout the upper one-half of the liner

at TDC opposite the thrust side of the liner

near the middle of the thrust side of the liner
