The valve AVEC existed in ... 1922!

[Woodcutter]

Me what seems surprising to me especially is that one can still think that an effective invention in a field related to the internal aerodynamics of engines, invented to solve a problem of 1922, can still bring something 85 years later. ..

The pages of the magazines of the time (1919-1935) are full of innovations that would have their place today in the automobile. Almost everything was invented at that time but we did not necessarily know how to make it. I saw engine studies of the time and I can tell you that the engineers had understood everything and that we did not progress much except in manufacturing and electronic management of course.

It is not by chance that I speak of a field (aerodynamics) that did not exist at the time, at least in its current modeled form (there was some empirical knowledge). So the internal aerodynamics of the engines, I do not even mention it!
Progress does not exist only in electronics ...

You would be amazed bucheron studies of the time . We knew the aero but also the internal flows in the engines. Thus, I have seen studies on the turbulence in the combustion chambers depending on the location of the valves and the shape of the piston. Certainly, these studies were not as advanced as today (though ...) but we knew a lot already.
It is not because it dates from before 1930 that the technologies used were "contemptible". We knew how to do it. However, we had to allow time to do things. Trying to get a mill to take 9000 rpm when the vintage oils and alloys did not allow it does not mean that we did not know how to do it.
For me it is clear that they knew where they were going with the valve presented in 1er page.

be careful not to have a vortex without a hole or close too much on itself

hello to all..I recently forum with .. and I immediately made a vortex for my dyane 435 ...
with the engine that is so weak, I immediately noticed a substantial increase in torque.
not leaving my imagination in my pocket, and given that the vortex is a little less efficient at low revs, and not at all efficient at high revs from what I read ... I found a way to vary the speed of rotation easily ..; according to the process almost similar to what I have just read here above with the turbines "thing trick" ...
a conical "bushel", undoubtedly controlled directly by the accelerator pedal for the first tests ... then with the tachometer, but here I am not able to tinker with electronics ....
here is a drawing, and I would like your opinion ....

I really like the principle.
But rather than a system managed by the electronics I would rather try with a tarnished spring and I will play on the suction of the engine.
The motor sucks the valve which is retained by the spring and thus evolves in the tubing to increase or reduce the section.

Well ... and if you like Bugatti, you're definitely a good person.

well me either, I do not like electronics at all ... except internet of course, which can not do without a computer ...
good.; The first tests I did with this adjustable "bushel" are a failure ...
- either that the "with" that I put corresponds perfectly to my engine
- either that the system influences the rotation in such a way that the flow is no longer "so good" ...
when I say failure, I mean that I did not feel any improvement ... or disturbance, it still works as well ...

As for being good because we love bugatti,
think again ....
there are also big idiots and "super pretentious" in the bugattists.

my thing to me is passion, and nothing else ....
I am passionate about "energy savings",
deuches, bugatti, and life in the countryside ... if possible in deuche ...

Hello

and since the vortex is a little less efficient at low speeds, and not at all effective at high speed from what I read

.

I think that at high speed it is more efficient
For the hole in the middle, I do not agree it's been years that I use it well before AVEC exists, and I did not invent anything, as it is said above that exists in other forms since very long, just improved the principle of making a swirl after the butterfly ..
It is more the angle of the pallets which must be adapted to the regime
Low speed, high angle, high speed, larger angle
I lost an 10 to 15 kmh on top speed
Installed on a plane Lycoming engine we lose 50Rpm in full power by mounting either 2400 rpm instead of 2450rpm.
the position of the turbulator in the tubing is important
the turbulator must be placed in a duct section with its outlet still in a duct, not in a solidium
you have to let the whirlpool do naturally are central vacuum hole ..
Those who have automatic transmissions automatic depending on the location of the depression catch with a turbulator that the speeds change faster, because of a false indication of depression,

The torque gain found on a carburettor engine without correction corresponds to a slightly richer market which is the maximum power step (so no saving but just more power and better combustion)
on a vehicle with eLambda this correction is made automatically or the economy.
