Moin Leutz! I just got my hands on an advertising flyer from Air-Tec-Systems… They advertise with a “spool” on the intake hose, which puts the air into vibrations… the flyer says: “By means of an electric coil, which is built directly on the intake tube or the intake tube, exactly defined resonance vibrations are transmitted to the intake air. The vibration frequencies excite the molecular structure of the air in such a way that humidity wass It is split into its components. Freed hydrogen provides for a more intensive combustion of the fuel, which avoids harmful deposits and reduces the proportion of soot particles, as well as unburnt hydrocarbons in the exhaust gas. On the other hand, the energy efficiency of the combustion is significantly improved and this results in a noticeable reduction in fuel consumption” In my opinion, complete peasant fishing… especially when one sees the pictures in which these “Spule” with armored tape on the intake tube…. How do you see that?! Just interest me…! Have a nice weekend! Groetjes, Boppel
