🔍 Key Concepts

• Crosshead diesel engine geometry and how the piston, piston rod, crosshead, and crankshaft move • Difference between reciprocating motion (back-and-forth in a straight line) and rotary motion (circular movement) • Purpose of a crosshead: to separate linear piston motion from crankshaft rotation and protect cylinder from side thrust

💭 Think About

• Visualize the path of the piston crown as the engine runs: does it move in a straight line or in a circle? • Think about what the crankshaft does: does it rotate, move back and forth, or both? How is the piston rod connected into this system through the crosshead? • Ask yourself: in a crosshead engine, is the piston rod allowed to swing in an arc, or is its motion constrained to a straight line?

✅ Before You Answer

• Be clear on the definition of reciprocating motion (straight line, back and forth) vs rotary motion (circular path). • Remember that the crosshead guides control the path of the piston rod—what kind of motion do they force it to follow? • Check which engine component actually rotates (think: crankshaft and crank pin) and which components only move back and forth.
