Quenching

CO-incidence or???

I spent three hours last night researching the same question!

MopeKid - pretty close - but what you describe here -

This causes the compressing intake charge in the cylinder to be squeezed violently into one part of the chamber, imparting a huge amount of turbulence to the intake charge; this greatly reduces the chances of detonation during compression and allows you to run a higher static compression ratio with lower octane pump gas.

is actually SQUISH.

Quench is the "dampening effect" created by the surface area of the squish pads after detonation.

Here's what I found....I highly recommend this article - easy to read and provides a great summary..not completely but close (they actually get the terms wrong as well!!)....:-D

..and in the interests of learning I also recommend getting over the fact its a Cheb magazine..... :read2:

Theres also this - simulating the difference between a broad squish area and a compact one
