🔍 Key Concepts

• Study the location of part X in relation to the crankshaft and crankcase. • Think about what system usually runs along the engine base and main bearings to protect moving parts. • Compare the shape and connections of X with how fuel, water, and control linkages are normally drawn on engine diagrams.

💭 Think About

• Is part X located near moving parts that need constant lubrication, or near components that mix air and fuel, or near cooling passages? • Does X look like a rigid pipe or a mechanical linkage with joints and pivots? • Which system (fuel, water, lube oil, or controls) is most critical right at the lower end of the connecting rod and main bearing area?

✅ Before You Answer

• Verify whether X appears to enter the crankcase near a bearing surface. • Check if X is drawn like a piping run (smooth bends, flanges) rather than rods or levers. • Confirm that X is not connected to the fuel injection equipment or cooling passages higher up on the engine.
