Explain Quench to me.....GO!

WOW....I get it!!!!! Thanks, that is a great explanationt for someone like me who doesn't have a wide background in engine theory....actually...almost no background. I have been thinking lately that this site could use a "school" forum with detailed explanations of many of the mechanical things associated with engines and engine building. Your post could be the first one.
I know I could use a detailed explanation on Timing and the terms used when people talk about it. Thanks again.
