Technical Screen under carb for fuel atomization?

BS, or it would have been done by the automakers? Another 'Tornado'? Anyone ever try it?

this should be fun to watch...

 

I suspect that there might be some small benefit on an intake with a large, open plenum. Maybe better fuel distribution, maybe only at mid-range and lower RPMs. But it would probably be difficult to measure a real improvement.

Though it looks like it would help to keep leaves and twigs out of your engine if you're prone to running with no air cleaner...

 

Fuel atomization already happens during airflow past the venturi.
Vaporising of fuel droplets [the important part] requires heat from the combustion chamber

screens were used on blowers for protection

 

Must be some big ol fuel drops. Or does it just keep out nuts and bolts?

 

Yep, for a blower. Anything big gets in there, you've got a catastrophe.....

 

nice stainless screen.

 

Only works in conjunction with clothespins on your fuel line.

 

When Allison was developing the V-1710 series of aircraft engines (supercharged) they had backfiring problems and installed 'backfire screens' very similar to the photo at the intake ports with varying degrees of success.

 

SNAKE OIL

 

I always liked the kind with little propellers in the base. Is that what you were refering to when you mentioned "Tornados"?

 

My dad told me he actually tried this on his new 71 Dodge Demon with a 318 during the fuel crisis in the early 70's. Didn't work worth a shit....

 

I can see fuel collecting on the screen and becoming droplets. Then dripping into the manifold causing a rich cylinder where ever it flowed

 

Yeah, small nuts and screws are OK, but the big ones are a no-no.

The Tornado is old technology......The Turbonator is where it's at

 

About as useful as scented toilet paper.

 

Its to keep crap out of blower !!!!

I have never heard of for ""Fuel atomization "" on blower ,
that would be Snake oil

 

Looking at the pic, that looks to be a Weiand blower, so that screen is to keep shit out of the rotors. Nothing to do with the fuel mixture, when that blower is sucking the mixture down it doesn't have time to stick to the screen, it's going into the blower fast! And any small debris sucked into the blower would probably lock the rotors up instantly, causing one large BOOM!!!! That or sound like a rock crusher while it's tearing itself apart!

"BTW, in some applications adding a carefully cut and placed screen, under the carburetor spacer can be added too catch debris that might fall into the carburetor,and save you a good deal of engine damage , with the potential added ubenefit that the screen tends to increase fuel air atomization, by breaking up fuel droplets as they enter the plenum, area of the intake, a screen with 1/8" holes has only a minor effect on air flow rates"

 

I worked on some over the pond cars that have a heated plastic peace somewhat like that and if you didn't have voltage to it and working the car would run like crap.

I like the comment about the carburetor atomize the air fuel.
The rest of the induction system job is to keep it in suspension and moving to the combustion chamber.

 

I would think if you where to use screen to Fuel atomization the intake is a poor design , Also if you service / tear down your own Blower , put a Rag in the rotors to break or torque rotor gear bolts ,

 

You don't need this! Just get some "Cow Magnets", tape them to the fuel line so the fuel molecules get lined up properly, and they'll stay in proper alignment until they hit the combustion chamber. Oh yeah, be careful to use the proper pole orientation when taping the magnets on. Duct tape works best (especially in Canada)!

 

you don't even have to go over a pond to find one of the heated ones....

 

That's interesting, OEM instead of heat riser and thermo air cleaner?

I happen to like scented toilet paper.

That's the stuff Jim. The first ones I remember were mazda I think.

 

Brings back memories and it's Veterans Day - when in the Air Force in early 70's, this was a trick going around with my AF car buddies to save fuel - we made $1200 a yr then. We used hardware cloth which is much finer than the pix above. Can't really say it helped but on a 57 Chev with 283, it did get great mileage ~20mpg. It would have helped my old high school buddy that took the air cleaner off his dad's 65 Olds because he liked the sound it made at WOT. On one of his removals (probably his last) he dropped the cleaner wing nut down the carb and it got lodged between the intake valve and valve seat -busted!
