Brainfart about effeciancy
Has anyone ever walked in the mall, and seen one of those fog fountains? theres a little ultra sonic vibrating thing that causes the water to turn into fog. Could a similar thing make diesel fog, and then just have a carb type intake to mix it? I'm sure the fog droplets are smaller than injector droplets, thus burning way better.

With that in mind if the fuel is already present in the combustion chamber on the compression stroke then the fuel is going to ignite as soon as the air in the chamber gets hot enough, not when it's supposed to.
The diesel fuel must be injected at precisely the right moment or you will have massive preignition problems due to the fuel burning way too soon in the combustion process.

Yeah, i realize that you cant have your mix igniting before TDC, but mabye this idea would work better in a SONEX piston engine
Anyone think that one of those ultra-sonic things would atomize the fuel?

Diesle Fog Experiment
Filled up my mother in laws "cool mist" with diesel...
Well, this isnt a solved case...
The diesel didnt really mist, but it did bubble like the water, the same way the water does when it is too deep.
I think it needs a little heat to thin it out a little
Because the cool mist is plastic, and not mine, I didnt want to put hot diesel into it.
Because of the fact that it was aggitated though, I believe that it could be done by either heating the diesel ot getting a stronger piezo evaporator thing.
PS how did fuel not burn before TDC in IDI engines?

It didn't burn before it should in an IDI because the injectors didn't squirt until the proper time, which is a few degrees before TDC. Injecting before TDC gives the fuel a few milliseconds to start burning, so that the energy is released at the proper time.
I think you might be getting confused with the direct injection that started with the Powerstroke. Before that the indirect injection (IDI) still injected fuel into the cylinder. There was a prechamber that the injectors fired into, and that was open into the cylinder. So it didn't inject directly into the cylinder it indirectly injected. Clear as mud?

OK, so...
I dont understand these IDI engines, The powerstroke injects right into the compression chamber right? but IDI's inject right on the other side of the intake valve? Or is there a chamber in the compression chamber kinda like a flathead design?
My 1990 7.3 i guess was IDI, but i know more about the PSD cause i want one
