Pinking conclusion??

After all of the recent arguing between some people in here about pinking
has anyone made a decision?

 

Listen to Dave, he's a very intelligent bloke and knows all there is to know
about engines! One look at his site will confirm this. It may be basic to
look at but its the content that matter - a very interesting read!
I'm not pretending i know that much about pinking (i drive a diesel so its a
way of life ), but i've never heard the description Steve gave in his post
(before all the arueing started).

 

Indeed. There's a lot of rubbish being talked about the subject but I
believe a lot of it boils down to how you define pinking. As far as I'm
concerned, it's caused by pockets of fuel combusting early, before the flame
front gets there (it's best to think of a spark plug ignition creating a
flame front moving in a wave motion rather than the more simple 'explosion'
happening in the engine - you don't want it explode!). There can be a number
of different reasons for this happening and also different things which
sound like pinking. Of course, if you define pinking as something different
to this (I always used to get confused with pre- and post-ignition). To me,
pinking is a funny thing to call anything anyway and it seems to me like
people use it as a rather vague description of 'something rattling in the
engine'.
Whatever, Dave Baker has been posting on various automotive newsgroups for
years now and I've never had reason to call into doubt anything he says - I
think I may have had one of my posts called into doubt by him a few years
ago and found him to be absolutely correct on the subject... I think it had
something to do with optimum gear-change points and torque vs. BHP - a flame
war which waged for a long time until Dave posted his definitive conclusions
on the subject.
If I could afford it, I'd send my XU engine down to him in a flash

Chris.
