🔍 Key Concepts

• Effect of piston-to-head clearance on compression ratio and engine performance • Which components are realistically and safely adjusted in service to change top clearance in a large low-speed diesel • Mechanical consequences of adding or removing material (spraying) vs. adjusting bearing/shim thickness

💭 Think About

• Ask yourself which part is normally designed to be adjusted to correct the piston’s top dead center position relative to the head • Consider what might happen to heat transfer, stress, and balance if you ‘build up’ either the piston crown or the head by spraying metal on them • Think about how changing the effective length of the connecting rod/crank relationship would affect piston travel at top dead center

✅ Before You Answer

• Verify which of these options would be considered a standard, class-acceptable maintenance adjustment rather than a major design alteration • Check which method preserves the original combustion chamber shape and cooling arrangements • Confirm that the chosen option does not introduce untested welded or sprayed surfaces directly exposed to peak combustion temperatures and pressures
