PD-5 is a revolutionary new fuel conditioner which uses the combustive power of microscopic aqueous colloids which can be added to all types of fossil fuels.

Aqueous colloids? These are minute clusters or droplets of ionically-charged water molecules. PD-5 is extremely similar to water, except that it disperses easily and evenly throughout the fuel in your tank. By contrast, normal water will not mix easily with fuel and, typically, it will settle either on the top or bottom of a tank of petrol or diesel. PD-5’s green colour is simply a tracer dye which can be analysed to prove the authenticity of an example of our product.

How the PD-5/fuel mix exists
PD-5 exists as a colloidal sol within the fuel. It physically (rather than chemically) binds with the fuel to exist as an extremely small (less than one micron) droplet of PD-5 encased and bound to an envelope of fuel. The droplets of PD-5 are so small that they form a very stable and homogenous mix with the fuel. The nano-sized mix is small enough and stable enough to pass through any fuel filter or other purification device.

How PD-5 affects combustion
During fuel droplet combustion the fuel droplet burns from the outside to its nucleus. This is a time dependant process, naturally the larger the fuel droplet the longer it will take to burn completely and conversely the smaller the fuel droplet the quicker it burns. PD-5 accelerates the combustion process because as a fuel droplet containing a nano droplet of PD-5 burns from its nucleus it heats the PD-5 turning it to gas which, as the temperature gets greater the pressure caused by the PD-5 vapour is greater than the surface tension of the fuel around it and causes a micro explosion that fragments the fuel droplet. This fragmentation of the fuel droplet leads to a greater surface area for the fuel to burn and hence the fuel burns more quickly. This accelerated combustion leads to more energy from the combustion being available to the piston (less energy going down the exhaust), it also leads to much less unburnt fuel exiting from the combustion chamber and entering the exhaust system.

What physically happens to the PD5 during the combustion process is very simple. PD5 contains no heavy metals, detergents or ash forming components. The by-products from its consumption are H20 in the form of steam and a trace amount of CO2 that are also the natural by-products of the combustion of fuel. Through the use of PD5 nothing alien has been introduced to the engine or fuel system. PD5 can therefore not cause any damage to an engine or boiler or indeed does not produce any gaseous pollutant by its use.

An infinitesimal amount of ash is formed due to the combustion of the specific tracer dye, the amount being so small it can be ignored.

PD5’s cleaning power
The phenomenon of micro explosion detailed above explains how PD5 reduces the emissions and fuel usage from an engine or boiler. Some fuels due to their nature tend to smoke and there are various reasons for this. The main reason however is that during the combustion of smoky fuels as the fuel droplet burns to its nucleus it will extinguish itself leading to the formation of soot. This is also a the case when partially burnt fuel is forced into the exhaust. The consequences of the formation of soot within the engine are well known; most important being the fouling of heat exchange surfaces in boilers and a resultant decrease in heat transfer across the heat exchange surface due to the insulating effect of the carbon deposits of them. Also if carbon deposits form on the injectors or fuel spraying nozzles they do not spray the fuel according to their design and hence larger fuel droplets are formed which take longer to burn and ultimately increase the amount of smoke which in turn fouls the heat exchange surfaces and leads invariably to more inefficiencies.

How PD-5 Improves Engine Efficiency
The efficiency of an engine or boiler is proportional to the amount of fuel it has burnt. To combat the deposit of carbon, boilers and engines require servicing at regular intervals to clean the system and to clean or change nozzles and injectors. The gas generated by the boiling of PD5 during the combustion process has been shown to have a tremendous cleaning effect on engines and boilers that already have carbon deposits. Therefore PD5 also increases the efficiency and reduces emissions of engines and boilers by its cleaning action. Regular use of PD5 leads to prolonged operation at peak efficiencies and prevents the formation of carbon deposits on injectors and nozzles that lead to incomplete combustion of the fuel and hence environmental emissions such as CO, unburnt HC, particulates and smoke. Also the fact that less fuel is required to be burnt to achieve the required power in an engine or the required amount of heat in a boiler leads directly to a consequent reduction in the amount of CO2 released into the atmosphere.

This has been demonstrated in testing where fouled engines have been cleaned by the use of PD5. It is worth noting that further evidence of this occurrence has been shown by the fact that particularly dirty engines or boilers initially show an increase in smoke emissions as the engines are cleaned before a reduction when PD5 is first used.

How PD5 removes water from fuel
PD5 also has the ability to remove small amounts of water from fuel. PD5 is water soluble so it mixes easily with water and is able to bring a limited amount of the water into the colloidal sol discussed previously.
