← TechnologyWhich outcome occurs in a lean-burn engine when fuel injectors degrade unevenly?
A)Catastrophic pre-ignition and engine knock✓
B)Complete combustion efficiency optimization
C)Uniform temperature and pressure distribution
D)Minimal carbon monoxide and soot creation
💡 Explanation
Uneven fuel distribution triggers localized hotspots via incomplete combustion because of misfire patterns; Auto-ignition results therefore damaging engine components, rather than optimized complete combustion due to non-uniform air-fuel mixtures.
