← ScienceWhich risk increases following the adiabatic expansion stage in a large-scale reciprocating engine?
A)Liner cavitation cold corrosion initiation✓
B)Excessive localized charge air cooling
C)Fuel injector piezoelectric element cracking
D)Scavenging port preignition detonation risk
💡 Explanation
Liner cavitation is likely due to dramatic pressure drops and temperature gradients. Adiabatic expansion causes rapid piston movement, which reduces local pressure, promoting bubble formation and subsequent collapse near cylinder liners due to the Bernoulli effect; therefore liner cavitation, rather than other thermal alternatives, becomes prevalent.
