🔍 Key Concepts

• Function of compression rings in a diesel engine piston • Where gas pressure actually acts on the ring to force it against the cylinder wall • Difference between back of groove vs bottom of groove contact

💭 Think About

• Think about how the ring is pushed outward to seal against the cylinder liner: which surface must receive the gas pressure? • If the ring were bearing firmly on the other surface, would it still be free to move and follow cylinder wear? • Picture the cross‑section of a piston ring in its groove—where is the clearance usually left?

✅ Before You Answer

• Verify which surface (back or bottom of groove) carries most of the gas loading that pushes the ring outward. • Consider whether the ring needs vertical freedom to follow up-and-down movement or wear patterns. • Recall that poor contact on the correct face would lead to blow‑by and loss of compression—identify which contact surface prevents this.
