This video has several million views. In the video, Ufa inventor Farvaz Munirov improved the air supply system by installing a metal ring. He assures that this is a simple matter, and such an invention helps to save up to 4 liters of gasoline per 100 km.
The author says that the whole secret is in the vortex of air, which creates a metal ring. This allows air to mix better with gasoline.
In the discussion of this “miracle”, motorists disagreed. Someone thinks that the idea is successful and that it is necessary to test it, someone accuses the inventor of not knowing the laws of physics, and such an “improvement” can just ruin the engine. But what really?
Expert opinion
Alexey Reviniexpert “Behind the wheel”:
– What a knowledge! Attempts to spin the airflow were still on cars with carburetors nearly half a century ago. Then something like tangentially placed blades were also attached to the carburetor from below, which was supposed to spin the flow. Here the author of the idea proposes to swirl the flow after the throttle assembly, before the inlet pipeline. The only problem is that the air paths going to each cylinder after the carburetor or throttle body are a different shape and length.
In addition, the geometry of these channels has been carefully selected in the factory to obtain an equal filling of all cylinders. Therefore, “one turn of the current at all” will have no effect.
But factory engineers have long turned the flow and chose the shape of the intake tract. By properly shaping the channel, they have mastered creating a vortex in the cylinder after the mixture has passed through the open valve. Such a vortex is very useful, because it improves the flushing of the cylinder and optimally mixes the air with the fuel supplied by the injector.
our verdict
The idea is not new, many people have tried this. But in this version and on these cars it is basically useless. This extra ring does nothing, although it is also not harmful to the car. And as for the enthusiastic reviews of the owners … Probably people fall under the charm of the “inventor” and see what they seem to see, supposedly a positive effect.
