🔍 Key Concepts

• Study where label 5 is pointing in relation to the piston, piston pin, and crankshaft. • Review the function of a connecting rod and where its ends are located in a diesel engine. • Consider what the crown of a piston is versus parts that are located near the crankshaft.

💭 Think About

• Is label 5 located at the top of the piston (inside the combustion space) or down near the crankshaft and bearing area? • Which listed choice describes a part that actually connects to the crankshaft journal in this type of V-engine? • Looking at the shaded colors, does label 5 touch moving rotating parts (like a crank throw) or just the upper piston surface exposed to combustion?.

✅ Before You Answer

• Verify whether label 5 is drawn around a circular journal and bearing cap near the crankshaft, or at the piston top inside the cylinder. • Confirm that the piston crown would be in the combustion chamber at the very top of the piston stroke, not down in the crankcase area. • Check if the term you choose reasonably matches a component that would house bearing shells where the connecting rod attaches to the crankshaft.
