← TechnologyWhich risk significantly increases when lean fuel mixtures occur in a two-stroke engine?
A)Decreased engine cooling capacity
B)Increased particulate matter emissions
C)Elevated cylinder head temperature✓
D)Premature degradation of fuel injectors
💡 Explanation
Lean fuel mixtures raise cylinder temperatures because detonation tendency increases due to insufficient fuel cooling; therefore, cylinder head temperature significantly rises, rather than experiencing only decreased cooling capacity at other cylinder locations under these conditions.
