Not sure if we have talked about this sort of thing before or not. Im bored at work so I thought Id see what some of you more educated gear heads had to say about this theory/concept.

One of the things that sometimes can hurt an engines performance is physically how the fuel gets delivered into the combustion chamber and how much of that fuel is actually atomized. More specifically, how do you avoid fuel from sticking to valves, intake runners, pistons, and any other carbon buildup already in place? Or, does that really even matter that much in terms of how it effects performance?

I think a typical thing you hear about when tuning an engine, is fuel that is not atomized and "sticking" to the intake runners before reaching the cylinder. One way(supposedly) to help this is to polish the intake runners. But what about the valves? Can you polish the valves to help avoid this "sticking" effect the fuel has? What about carbon buildup on the pistons and valves? Should this be cleaned regularly with some sort of "fuel system cleaner"?

Basically, what can or should be done to help keep fuel atomized during the intake and compression strokes, to more efficiently burn the fuel during combustion?
