← TechnologyWhich outcome occurs when localized 'hot spots' raise piston temperature?
A)Premature detonation within combustion chamber✓
B)Increased volumetric efficiency within cylinder
C)Lower exhaust emissions under lean burn
D)Decreased friction against cylinder wall
💡 Explanation
Premature detonation results from localized heating because autoignition temperature is reached before spark ignition initiates; this is knocking. Elevated temperature causes pre-ignition, therefore detonation, rather than controlled combustion under normal timing regimes.
