← TechnologyWhich consequence results when excess fuel bypasses cylinder combustion?
A)Oil dilution and bearing damage✓
B)Increased exhaust back-pressure results
C)Lean misfire occurs sporadically there
D)Catalytic converter performance improves acutely
💡 Explanation
Oil dilution occurs because excessive fuel bypasses the piston rings due to imperfect sealing. This leads to crankcase contamination via oil dilution, causing premature bearing wear therefore requiring costly repairs rather than temporary power loss as with misfires.
