There are lots of products which claim that they can cause
stirring, swirling (cyclone) or turbulence (Superione) in the
intake manifold to achieve a better fuel/air mixture, thus giving
more power. I really don't see how it works....
FROM A TECHNICAL POINT OF VIEW....
When Superione's small amount of turbulent air is injected into the
intake manifold, its gonna bang into the large amount of air
(normally aspirated) which came in via the air-filter side. This
will cancel out any small amount of "special turbulence" almost
immediately! Everything will become mainstream again.
If not, we also have to remember that the intake manifold is not
straight. It has bends and corners....and that will also cancel out
any special air-flow profile previously created.
The biggest limiting factor is when it reaches the engine block,
where it has to be squeezed through the tiny valve openings to
enter the combustion chamber. Logically, I suspect that any
swirling or turbulence will be evened out while going through those
openings.
(Fuel and air are mixed inside the combustion chamber, not before
that).
But lets give the benefit of the doubt and assume that the
swirling/turbulent air does get into the combustion chamber. Once
inside, it becomes subject to the super fast "banging" and
"pulling"action by the reciprocating piston
(compression/expansion). That will also cancel out any swirling or
turbulence previously created too.
From the above, I can't see how any air-flow profile achieved in
the intake manifold can be used to achieve a better fuel-air
mixture in the combustion chamber. The only thing which matters is
probably the air flowrate (and not the air-flow profile).
I'm not a car expert and may be wrong though....but from a
technical point of view, I'd dare say that these devices are all a
bit suspicious (sorry).
FROM A COMMERCIAL POINT OF VIEW....
We would think that if these devices do work (and are so
affordable), then car manufacturers would all be rushing to include
them in their cars by now. After all, who doesn't want to advertise
an increase in power without any increase in fuel
consumption?
These are only my own assumptions and deductions.....I may be
wrong....
