🔍 Key Concepts

• Single-acting diesel engine geometry: where is pressure highest in the stroke? • How piston movement affects oil film on the liner (where oil is wiped off vs where it can build up) • Effect of combustion temperature and gas pressure on lubricating oil near the top and bottom of the stroke

💭 Think About

• Visualize the piston moving from bottom dead center (BDC) to top dead center (TDC). At which part of the liner is the oil film most exposed to high temperature and pressure? • Think about where piston rings reverse direction. Does that help or hurt oil film retention? • Which area of the liner is most likely to have its oil film burned off or squeezed out, making lubrication hardest to maintain?

✅ Before You Answer

• Be clear on the difference between thrust sides (major vs minor) and the circumference at the ends of the stroke • Consider where ring reversal occurs and what that does to the oil film • Focus on which region experiences the harshest combination of heat, pressure, and wiping action, not just side load
