Again, "quench"- as it's used to describe the action caused by the quench pad of the head and the piston deck near to and at TDC in a (usually) wedge shaped combustion chamber- is a matter of expediency!!!!! It is simply easier to say quench than to use another term. The term quench AND squish are both misnomers- squish is just as wrong as quench. But in the context we use it here on the Hotrodders forum, and on other automotive forums, and among engine builders, the term quench is readily recognized for what it is.
But whatever you want to call it: quench or squish or "squench" (a non-word I and a few others use occasionally)- the fact remains that IT IS IMPORTANT. To say otherwise sets the art of engine building back 50 years in a single stroke.
There's been some things said regarding "young minds vs. old minds". But one thing should bridge the gap is to recognize the importance of this in the first place- when used in the proper context.
And the proper context is the next thing I think is important. It needs to be realized that quench- as we use it here- doesn't necessarily apply to 2-strokes, Hemis, or et cetera. Those designs have their own problems and solutions that do not necessarily have anything to do w/quench in the traditional sense- to a large degree those designs do not have heads w/quench pads or pistons that are designed to use those quench pads.
