🔍 Key Concepts

• Trace the force path from the burning gases on top of the piston down to the crankshaft in a crosshead diesel engine • Think about which long members in this engine work mostly in compression and which are primarily in tension during the power stroke • Identify what the tie rods actually do in a large low‑speed marine diesel and how they are loaded when the cylinder fires

💭 Think About

• When the combustion gases push the piston down, which specific part directly beneath the piston crown is being pushed (compressed) rather than pulled (tensioned)? • Look at the illustration: which of the listed parts lies on the straight line between the piston and the crankpin, and which parts are more for supporting/holding the engine structure together? • Ask yourself: do turbochargers or lubrication telescopes normally carry combustion forces, or are they mainly for air and oil flow?

✅ Before You Answer

• Verify which member in the drawing connects the piston to the crosshead and carries the gas load downward • Confirm that the tie rods run from the bedplate up to the cylinder block/entablature and are mainly in tension to hold the structure together • Eliminate any components whose primary function is air supply or lubrication, not transmitting firing forces
