← ScienceWhich outcome results alongside a decreased flash point in biofuel powered engines?
A)Increased Cetane through Fuel Cracking
B)Autoignition via rapid chain branching✓
C)Flameout due to over-leaning condition
D)Soot production from fuel decomposition
💡 Explanation
Autoignition occurs when fuels reach their autoignition temperature and chain branching accelerates the rate of radical production because decreased flash point lowers autoignition; therefore uncontrolled combustion occurs, rather than controlled burning needing a spark.
