🔍 Key Concepts

• Direction of firing forces on the piston, pin, connecting rod, and crankshaft in a two-stroke diesel engine • How journal bearings carry load (upper vs lower halves) when the crankshaft is under power • Difference between main bearings and connecting rod bearings in transmitting combustion forces

💭 Think About

• Trace the path of the combustion force from the piston crown all the way to the crankshaft and bedplate—where is the force ultimately reacted? • Think about which half of a split bearing (upper or lower) is actually compressed when the engine is producing power and the crank is being pushed around its rotation. • Consider whether any bearing in the system would realistically see the same load as all others, or if some particular location must carry the highest reaction.

✅ Before You Answer

• Identify which bearing surface (upper or lower half) is on the loaded side of the crankshaft during the power stroke. • Verify which component is responsible for supporting the crankshaft in the block versus connecting the piston to the crank. • Check whether the connecting rod bearing and piston pin bushing carry the same type and magnitude of load as the main bearing that supports the crank throw.

Which component will receive the greatest load in a two-stroke/cycle diesel engine?

Lower half of the connecting rod bearing at the crankshaft end of the rod.

Upper half of the main bearing.

Lower portion of the piston pin bushing in the connecting rod.

All bearing halves share an equal load.
