← TechnologyWhich outcome occurs when incorrect fuel stoichiometry affects turbocharger efficiency?
A)Detonation risk becomes elevated significantly✓
B)Bearing wear increases substantially
C)Compressor surge probability escalates rapidly
D)EGT values decline unexpectedly greatly
💡 Explanation
Detonation risk rises due to lean mixtures causing hot spots, which triggers uncontrolled combustion via autoignition. This is because increased cylinder pressure and temperature lead to detonation, therefore, risk of detonation elevates sharply rather than other mechanical failures or diminished EGT.
