Fuel Saver: turbulence generator

[Other]

Hello Ncl

Get mad! take a day and make a turbulator like the one in the photo in yellow, the photo was made a long time ago before the digital kodacs. it is the one that was in my Camaro then in the Buick and actuellent, it is this model that works the best of those I have made. it takes an afternoon to do it, and 2 hours to put it down for a guy not too used to fiddling with the mechanics. Then you forget that is installing the vehicle for life.

Install it without telling your wife and let it roll without a kidney tell her, you will see these comments. You will see that it is not a placebo effect.

hi, good after 2000 km with my new mount on the focus: 6l / 100, 6.1l / 100 same as without!
on the BM I did a good job as it should: no change in appearance! after qlq km I would see but I have no illusions, I begin to no longer believe it, yet everything is there; similar model elice / car, I'm starting to believe in poison !! (the plot again him !! )

it's not intoxication

Right now my feet are a little heavier and driving 130 on the E9 with the ups and downs, I used to do around 11,5l 11,8l and there every time 9,6l.
The only difference in driving is that I don't ride laps.
I raise in 5th at 40 km / h (light under regime), but as fast as the others because I have torque.
A if, when I see a big hill, I happen to accelerate towards the end of the descent to 150 170 so as to go up in front with the foot raised so as to end up at 120 130

hi patrick, i'm not accusing, but i'm skeptical, since, if i understand correctly, you changed your behavior, it distorts the results!
on my side, for the additional couple: nothing noticed! however the choice was made according to the advice seen here you may have seen in my private gallery the contraption.
we have the same type of car, there is no reason !!
the element placed in the same place: in front of the air flap which feeds the rectangular manifold, which sends the air into the 6 cylinders !!!!!
if it works, it's totally illogical, the turbulence is stopped dead by the air shutter! especially if it is not open to do !!!! so see your driving torque ..... after that happens in a volume, to be sucked by 6 different tubing before arriving at the injector near the cylinder head !!! there shouldn't be much left of the vortex, I'm not an engineer in fluid mechanics, but it's big, IS THERE AN EXPERT in this area?

Speed ​​up to 160/170 at the bottom of the ratings! is there anything better to be gaunt on the radar ... it would be better to reach this speed in climb ... Anyone already seen a radar in climb? ;)

Good my last record with my R21 carb fuel 1,7l TL, 6,1l / 100km! 1035Km with 64l! without any modification except NGK spark plugs and Beru cables for a few thousand kilometers. My last record was rather around 6,9l / 100Km.

The secret, 2x2 lanes every day at a stabilized speed between 110 and 120 km / h meter.
All this to remind that it is difficult to check a gain in consumption, especially on an engine with carburetor which can puff nearly 14l / 100Km in town and 6l / 100Km at speed stabilized at 110Km / h

Relaunch in 5th at 40km / h in sub-regime I am not sure that this is what is best to gain in consumption. I think it is more efficient to ride on the couple, even if it means downshifting.

Hello,
I believe in Andrée's turbulance generator on the application of the petrol engine, the question I ask myself:

1 per cylinder after the injectors it will not be better ???

Hello Denis

if I understand you put the vortex generator in front of the pappillon?

This is not where it should be, it is after the pappillon just before entering the manufoul (intake pipe) On a V6, air enters the filter> mass air flow> throttle valve> Turbulator vortex> then plenium (air distribution box) then comes one injector per cylinder on each inlet valve.
the entry is rectangular on the GM smoteur that it is the 2,8 l
3,1 or 3,8. or 4,4 l it's all the same except the sizes that change

As far as my driving is concerned, I haven't changed anything, I always drive at 100 -110 km / h before the turbulator and after.
For city driving repeat the gain is very low, the gain is felt only when the Lambda probe is operational, make sure that the probe is in good working condition, because if it does not work well, it will never be able to bring the precise corrections of the effect of the turbulator, you do not have to ask the original the good ones are made by bosch it responds faster.

Now there is a certain motor that the design of the tubing or the cylinder head makes a turbulence so it already has a direction of rotation
if we add a turbulator which rotates in reverse of what is already designed it may be harmful ...
For Angel
we install one per cylinder it is more complex to realize and more the entries in my cylinder heads are rectangular .. There is also the risk that the turbulators is irregular in their design and it is necessary to avoid making differences in filling of each cylinder (vibration generation) Well known problem with multiple carburetor assemblies difficulty of adjustment.
My first assembly is one per cylinder it still works, but the gain is not as spectacular as on Buick Park Avenue
3,8 liters is a fairly old multi-point auto injection 1988 with 4-speed automatic transmission with a lock torque it weighs 1470 kg when empty and I manage to make 7,8 liters per 100km measured several times on journeys from 400 to 600km
Sorel -Québec trip and approximately with 2 stops or 430km consumption 33,2 liters. driving at 105 km / h cruse control on a flat highway. Now it's up to you to believe or not ..
City driving average and 14,10litres per 100km.
With the same turbulator that I had on a Camaro I had good results, but I am still on the same designs of GM engines

Thank you André your explanations are very explicit!

Otherwise on Ebay at 10 euros you have "a process overview",

for those who prefer to buy all done!

André, when do you think of this turbulator? There are two informative photos when you click on an ad.

The angle not accentuated enough.
There is too much free passage in the middle; the slats should overlap, overlap more.
A two-spot weld seems a little light to me. Although it would seem that there is a retaining grid downstream.
A progressive curvature of the fins would be preferable, at a dry angle.

Perhaps the passage in the middle allows to conserve power reserve (without savings), so as not to restrict the engine. And the fins on the periphery allow to initiate a vortex movement, when the intake gases circulate less quickly and thus allow a substantial saving, but not maximum.

Hello again
on my car there is no catalyst
maybe that's why it works right?
