Olefins in engine
-Introduction of one double bond has little effect on anti-knock quality but two or three double bond results less knocking tendency except C and C
Napthenes and Aromatics in engine
-Napthenes have greater knocking tendency than corresponding aromatics.
-With increasing double-bonds, the knocking tendency is reduced.
-Lengthening the side chains increases the knocking tendency whereas branching of the side chain decreases the knocking tendency.
