PROZONEŽ FuelSaver combines two proven scientific fuel enhancement processes - a tin-alloy catalyst and a magnetic field - to condition the fuel, gasoline (petrol), or diesel before it reaches the combustion area of the engine. This is in contrast to standard catalytic converters that act on the exhaust gases after they leave the engine and thus, have NO EFFECT on the actual combustion process.

On entering the PROZONEŽ FuelSaver, the fuel passes over one (FS1) or more (FS2-FS4) complex alloy cores. The cores are specially designed to create turbulence in the fuel's flow path, enriching the fuel and maximizing the take-up of trace metals. The fuel then passes through a sintered ceramic magnetic core, which alters the free electron structure of the fuel, polarizing the fuel hydrocarbons prior to combustion.

The two processes, chemical and ferro-magnetic, essentially alter the molecular structure of the fuel to encourage better bonding between fuel molecules and atmospheric oxygen, thereby promoting a more complete oxidation of the fuel and, hence, a more efficient combustion process. Additionally, the metal alloy catalyst is deposited in molecular quantities in the combustion chambers, coating the vulnerable surfaces of the valves, valve seats, and piston rings to prevent overheating, aid sealing, and enhance engine lubrication.

The results of improved fuel combustion are: a significant reduction in harmful exhaust emissions; a noticeable increase in engine power output; and a measurable improvement in fuel economy.
