Smoke Screen

[Begle1]

Couldn't I take a little electric transfer pump out of some junkyard car, plumb one end into my Diesel tank, and put a nozzle into the downpipe in order to make a smoke screen?

What kind of nozzle would I want to use?
Since I don't want it to burn, I don't think that I'd gain anything from atomization... So I should just start drilling holes in a bolt until I find the size I want.

Diesel auto-ignites at 550-ish or whatever, but since the exhaust is really air deficient I shouldn't get flames, and the thing should be a smoke screen and not a flame thrower. Right?

I don't think that the fuel would smoke at all if I'm below a certain temperature, and then it smokes bluish-white until another temperature... Anybody have any clue what those temperatures are?

If I put the nozzle in the manifold it'd actually act as a coolant, unless there was enough air left over to afterburn it, under which case it would blow EGT's through the roof and spool the turbo faster... In order to do that controllably one would need a PWM on the pump connected to a pyrometer, and it'd only work under certain conditions... I don't want to do that yet.

Think that shooting it in the down pipe would be the best bet?

The other question is if that Color-Your-Smoke stuff would work if I'm shooting it into the exhaust... If it does, then I'd need to know how to rig it up like a bi-plane at an air-show and smoke red, white and blue...

Maybe I could do stacks and smoke red and blue at the same time...

No clue about temps, but I cannot wait to hear how the experiment goes.

Put in a center stack so that you can have red, white and blue.
