Hey guys, I am thrilled to find an engine site of this caliber. Now for some questions that are going around in my mind. Could this simply be a function of having three smaller, almost equal, quench areas with a secondary ignition source(the slot), firing the adjacent squish areas? Isn't the squish area just a necessary evil to allow an open combustion space for a reasonably, unobstructed flame front while keeping compression up? I have it in my mind, that maybe the quench is also an obstruction to the flame front, just less detrimental to our goals than crazy domed pistons in an open chamber.
I would be interested in trying an experiment on one of my four valve engines, that has more of a quench band with two small flats. I would like to machine small angled grooves of decreasing depth from the chamber wall, toward the cylinder wall. Kind of an imaginary starburst pattern, if you will. That would create multiple small squish areas while the slots allow ignition of all the adjacent areas.
I am not convinced that the chamber cares whether this is on the roof or floor, so I will probably modify a piston so I can do an A-B comparison at a reasonable cost. Maybe I could come up with a pattern that resembles a pineapple grenade, so there would be some poetic justice if I blow this thing up.
I would really like to see something like this excite the mixture in the chamber in a way I can quit giving up flow for swirl. Porting for increased swirl makes my head hurt.
If I am oversimplifying please take it easy on me, I might be sensitive....
Thanks for your time,
Kenny
