I thought I understood pinging very well until I started thinking
about it more and now I'm hoping someone reading this can help remove
my confusion.
Pinging is when the gas/air mix is compressing and heating up due to
the compressing to the point that it pre-ignites before the spark
plug's spark ignites the mix, right?
Distributor advance with more vacuum from more pedal push causes the
spark more in advance of the point in time that it would come without
romping on the pedal, right?
So if the point where the spark comes moves closer to the point in
time that the mix is tending to pre-ignite why doesn't this override
the pinging point and spark the mix before it could pre-ignite and
ping on its own.
Why does more spark advance actually increase pinging instead of
reducing it?
Why does low octane gas tend to pre-ignite more easily?
