Ok correct me if im wrong, but the atomisation of the fuel is determined by injection pressures and injection spray patterns. As far as i see it, a blatant lie or false advertising. Aside from the fact that "vortex" probably wouldnt make it to the combustion chamber in the first place. If anything i think it would hinder the atomisation of fuel within the combustion chamber. Yup, atomisation of the fuel is done by the injectors, not the air flow. It goes to show that they can sound like it's all technical etc, and still manage to catch a fool. Of all things, I would expect this to reduce air flow to the engine.
