🔍 Key Concepts

• Crosshead function in a slow‑speed diesel (how it connects the piston rod to the connecting rod and guides motion • Direction of gas pressure force on the piston during compression vs during power stroke • How that force is transmitted through the piston rod to the crosshead in both strokes

💭 Think About

• Sketch the piston, piston rod, and crosshead and draw arrows showing cylinder pressure during the compression stroke. Which way does that push on the crosshead? • Do the same sketch for the power stroke when combustion occurs. Does the gas force still act in the same basic direction on the piston and piston rod? • Ask yourself: in each stroke, is the crosshead being pushed into its guiding surfaces or pulled away from them by the piston rod force?

✅ Before You Answer

• Be clear about which side of the piston has higher pressure in compression and in power stroke • Track the line of action of the force: gas pressure → piston crown → piston rod → crosshead • Verify whether the gas load ever actually reverses direction on the crosshead between compression and power, or if it stays the same direction in both
