Q

The rotary motion of a diesel engine crankshaft is obtained from the up and down motion of the piston via the __________.

🔍 Key Concepts

• Basic parts of a diesel engine and their functions • How linear (up and down) motion is changed into rotary motion • Difference between valve-operating parts and crankshaft-driving parts

💭 Think About

• Which part is directly attached to the crankshaft and the piston to change straight-line motion into rotation? • Which listed parts are mainly involved with opening valves rather than turning the crankshaft? • Which item in the choices can actually transmit the main power stroke from piston to crankshaft?

✅ Before You Answer

• Identify which component is physically connected to both piston and crankshaft • Eliminate any component whose primary job is valve operation and not power transmission • Confirm which part experiences the main compressive force of the power stroke on every cycle
