Fuel Saver: turbulence generator

[Other]

Hello Nlc

Starting from this principle there should be a lot of turbulence in the compressors of turbojets (axial compressor)
although the flow is partially redrawn with fixed pallets.

If you examine the fux behind a plane propeller in static position it does not turn enormously, proportional to the pitch of the propeller, when the plane advances at its cruising speed, in reverse the flow turns only slightly, (it is enough to stick to another close-up plane, to realize that there is only a slight pitching movement in the groove)

The speed of the air flow in a pipe and around 200 km / h
It happened to me a turbine which started to turn, by the air admissions the efficiency becomes zero and even less, the rotation must be raised, that has worn out the tubing and break a rod of 1/4 6,3mm steel (probably a sudden stop of rotation)
Now I fix them securely.)
I tried simple multi-blade propellers, not a good result.
The only one I got is a well-fitting impeller with a covering blade. The one with a hole in the middle I have serious doubts. and the one with straight blades just folded for those who have a little bit of aerodynamic notions that is very rough ...
In the end it looks like a Françis turbine)

Although the best way to find out is to try it, you will be fixed.

But beware, little advice, everything you install after the air filter must be done in a neat and robust way, the engine swallows all that is walking in the tubing, and it is done quickly.

Again, I think you did not understand, I laugh that I will have to make a diagram

In fact, if the propeller blades are traditional, the air rotation should not be enormous. But if the blades are PARALLEL to the air flow, a bit like a paddle wheel ??

If the gas is around 200km / h in the pipe, your laminar blade device, operating with an external energy supply, will have to rotate an air flow all the more quickly as it itself will rotate quickly.
Given the violence and inertia of the gases, a lot of energy will be necessary to turn this paddle wheel. Big loss of energy, for what result?
Big stress on the blades, and risk of rapid breakage.
Debris ending up in the engine…
A metal device, solid, fixed, is better able to achieve the desired goal.

Well, if I find the courage this weekend, I take the shit down to see the butterfly behind and take action

[denis]

of souza:
I put my turbulator just before entering the "box from where the 6 tubes leave" It is placed roughly as on the photo of your car. Your big plastic hose, that's where I put it on the far right, just before the throttle.
I'll take a picture and send it to you, if you want.

having the same car, a good elice (I think), placed in the same place, I do not have the result!
the room is in my private gallery, comments are welcome

Make a turbulator with a piece of sheet metal!

[denis]

then, nobody, advises me for my turbu. from bm? (see in my private gallery): result 0
however, following the directions for placement (desouza who has the same car) construction etc ...
given your opinions

Hello Denis
If I give you my opinion you might get angry ..
Although when home they do something similar to you and it works. (the output of the blades and badly drawn)
On my first montages I never had good results
with simple propellers or with tubines or the paddles do not overlap one on the other, it must resemble the exhaust turbine of a GARRETT turbo even the longer outputs.
I had to do several to get performance and change the angles several times.
But there's nothing like trying, If you don't see any difference with a well-built medium turbine, it's that this engine has its own turbulence pattern, and I would even say that if you force it to spin wrong side of the builder’s drawing
the outlet angle of the turbine depends on the use you make of the vehicle, if you use it a lot you need less anguish and the turbulence appears at high speed, if you use it a little you need a lot of angle , but you will lose maximum power and you will know a significant turbulance at medium speed and economy.
The turbulator does not increase the filling on the contrary it decreases it (I am in contradiction with what is written on when home) when uax speed in the manifold 700kmh it seems to me a lot .. half would be more real.
Formerly voluntarily the engine manufacturers made engines with a long and narrow intake manifold, to favor the evaporation and the mixture and the fuel economy.
now we make short tubing without direct wide elbow in the engine this promotes power and filling
this is one of the advantages of V-shaped motors with short compact manifolds.
So there are two theory
One to make turbulence for the economy, but that harms the filling and the power.
the other to make a direct laminar entry without turbulence (just with the passage of the valves that gives more power, but I do not think that on a car one needs to make it take off on a short track.)

Since the last post did you have to try it?
You have my opinion but there is surely other way than mine to arrive at good results ...

[denis]

thank you, André for your opinion, so I will not insist with this elice, I will maybe make him turned the other way, what bothers me is that desouza has results, despite the elice placed in the shutter of air : amazing; I have followed the same model, not for the elice, there may be the rub, I need to persevere,

Hi everybody,

New participant, I tinker a bit and came naturally to this site. There's good and lots of ideas.

An engine that needs to be shaken off is a bad engine. The original turbling must be organized in the combustion chamber. In the new generations of diesel engines, including indirect injections, these mixing phenomena, whether axial or radial (at the axis of the jacket) are now relatively well under control.
It's always the same, the performance of the block is predefined within the framework of a specification which encompasses more than pure performance (the performance in our case), notions of sound comfort, pleasure, roundness and d 'elasticity, depolution, which require choices that are sometimes contradictory to those of efficiency (drawing of chambers, injection pump settings, intake manifolds, valve lift, etc.).
The turbine in the collector, a one-off advantage?, I am not convinced. Make me doubt. Mixing gases on an old engine is better to change the injectors, the pollution will decrease accordingly.
The future may belong to much sharper (more efficient) engines, but exploited by new transmission systems.
When you see what you lose in the chain of transmission of the movement, there's surely something to gain a maximum, ......
