Q

In a diesel engine, which type of wrist pin is fixed to the small end of the connecting rod and moves in the piston?

🔍 Key Concepts

• Different wrist pin (gudgeon pin) mounting styles in diesel/piston engines • How load is shared between piston bosses and the small end of the connecting rod • Which component the pin is locked to vs. which component it can rotate/move in

💭 Think About

• For each option, ask yourself: Is the pin free to rotate in both the piston and the rod, or only one, or neither? • Think about what the word describing each type (semi-floating, full floating, fixed) implies about which part is allowed to move. • Which design would describe a pin that is secured in the connecting rod, but allowed to move relative to the piston?

✅ Before You Answer

• Match the term "fixed to the small end of the connecting rod" with the correct design name. • Confirm which design allows the pin to move/rotate in the piston bosses specifically. • Eliminate any option whose name implies the pin is not free to move in the piston.
