Answer / karthick
knocking means a large sound pulsations heard inside the
engine cylinder.knocking occurs due to
detonation.detonation occurs due to the unburnt carbon left
out inside the engine cylinder.the unburnt carbon is
already in high temperature before the actual compression
cycle starts.when compression starts,its temp and pressure
is once again raised to peak value.as a result of this the
last part of charge collide with the first part and results
in detonation.

Answer / n. parandaman
Knocking is nothing but sudden increase in pressure inside
the engine cylinder. as the flame propogates from spark
plug it burns the mixture on its path until every mixture
is combusted. but due to the high temperature inside the
cylinder even before the flame reaches the mixture which is
already in or over ignition temperature it gets ignited
automatically. So due to the phenomenon the above said
sudden increase in pressure inside the cylinder occurs
resulting in knocking.
