← TechnologyWhich outcome occurs when excessive premixing of air and fuel happens inside a two-stroke engine cylinder?
A)Piston seizure from oil film washout✓
B)Catalytic converter overheating from rich mix
C)Crankshaft bearing failure from detonation
D)Exhaust port blockage from carbon deposits
💡 Explanation
When air and fuel are excessively premixed, oil film washout occurs because two-stoke engines use the fuel-air mix to lubricate cylinder walls, minimizing lubricating oil reaching cylinder. Therefore piston seizure results, rather than rich mixture, detonation, or carbon deposits from incomplete combustion requiring different conditions.
