Naaaaa ... This was designed to transit liquid propane to vapor in a most rapid time and shortest lenght.

Well ... Gasoline might work for a while, but you do understand that vaporizing gasoline will create carbon and once that carbon build-up start blocking everything, it's game over.

how will vaporising gas create sutt? I thought that only happend when burned at a low temperature

Because there is always a certain level of oxygen in any fluid. Although it would not allow and support combustion, it would create a form of oxydation and/or reaction, leaving residues inside.

But heyyy ... Try it ... You will see for your self.

But as I told you before, this was designed for liquid propane, not gasoline.

Ok so you say it might work, just not too long before the sutt starts blocking things? How long do you think I have: it's not like I'll run this thing often and long, and the injectors can be cleaned right?

Posibly ... With a big "P" and big "Maybe".
How long do you think I have:
Not a clue ... For I never work with gasoline nor this injector was design for.

Yeaaaa .. Maybe, probably, possibly ...

And you do understand you're walking your own path here ... :wink:

If you were any more vague you could run for office! :P I'll keep the injectors in mind but I think I'll start looking for alternatives

How hot is the gasoline going to get? If you get it really, really hot (far above the ignition point) it might decompose and produce carbon deposits but you'll be fine if you just evaporate it. Old-fashioned gasoline engines with carburetors do that and do not produce any carbon deposits in the intake manifolds.

To answer this question, I will just point out that my injector/evaporator was designed so the major part of the outside tube stands in the combustion flame, thus, it should become VERY hot.

Of coarse, the fluid flowing inside will contribute to drop that temperature and here too I have no temperature figures to offer, but it should run pretty hot I would say.

Luc, on this engine, where you place the injector?

This injector was for my DIY turbine and it was placed right in the middle of the flame tube, right into the flame.

"Build some augmenters" they said "they'll increase power" they said
Man what a pain in the ass this was to hammer out.

I build a 45 degree cone with the same length as 2*r*pi of the designed bellmouth and then welded it to a pipe, hammered it into the flare, cut it off and welded it to the augmenter body. Not quite 180 degrees put that's almost impossible to do.

To fit these things I need to cut out a V shape. Shouldn't be too hard to bend the flares the rest of the way after that has been done.

2 more to go

Not sure. I need to build 2 more augmenters, fix up structural integrity, fix fueling and sort out a remore start system

i have a question here why you didnt prefer to add conical augmenter to your engine. In an research paper by nasa says that conical Augs provide better performance than cylindrical.

They are conical, the photo angle makes it look like it's cylindrical
