With device speedpower is install in the breather hose going to air intake manifold there is a strong air sucksion inside the intake manifold when the car engine running. So we will get other source of air entering the device with combination of 7 element organic compound and catalyst entering into air intake manifold. The fuel and air mixture entering the air intake manifold is chemically correct stoichiometric ratio is 14.7 parts of air to 1 part of fuel. So the distribution of this mixture is uniformly to all the cylinders of the engine and recycles the unburned carbon into usable gases thus giving a higher fuel yield of up to 2 to 4 km. per liter of fuel. During burst of acceleration and deceleration the device help supply exact air and fuel mixture lean at the right time so that the engine can run with more power, economically and without the air pollutants that the result from poorly mixed unburned fuel. It does not mean that less consumption of your fuel will reduce the power of your car. As a matter of fact, it will totally increase the engine performance and acceleration of your vehicle. Thus, if less fuel enters into the intake manifold this means that all fuel will be efficiently burned completely with no wastages, the conversion rate of power speaks for itself. The concept behind this is what we call“AIR FUEL RATIO”, the mixture or combination of air and fuel should be just right, in order to avoid excess fuel wastage. The 7 element organic compound and catalyst cleans the incoming air and completely vaporizes the fuel injected into the intake manifold before entering the combustion chamber. The catalyst also cleans and expels the accumulated carbon deposits inside the combustion chambers thus getting the rated or maximum cubic inch displacement of the engine for maximum air and fuel entry with no fuel wastages. Together, all these features result to less fuel wastage giving maximum engine performance and a higher fuel yield with less harmful emission. I hope it is helpful for you.
