Surfactants are substances that lower the surface tension of a liquid. Surfactants allow easier spreading of the liquid because they reduce any interfacial tension. The molecules achieve this by adsorbing at the liquid-air, liquid-liquid and liquid-solid interfaces.
Surfactant molecules in IFT additives promote more complete combustion due to greater atomization and the consequent creation of larger fuel-air interface. Therefore, IFT additives contribute to generating more energy per mass of fuel consumed. The more complete burn accounts for the increase in fuel economy and lowered emission of carbon monoxide (CO), particulate matter (PM) and unburned hydrocarbons (UHCs).
Surfactant molecules in IFT additives have the ability to phase out the limited water normally present in fuel systems and other contaminants in the engine parts in contact with the fuel via a process called co-solvency. The surfactant molecules ensure that water and other contaminants in the fuel are distributed throughout the fuel in a stable, homogenous manner, preventing dangerous phase separation and eventually allowing the water to evaporate and other contaminants to be burned off with the fuel through uniform combustion.
As IFT additives phase out water in the fuel system and inhibit harmful microbial growth and contamination, they provide lifelong prevention of rust and corrosion in tanks and internal parts, which contributes to longer service life for the engine and parts.
Through uninterrupted use of IFT additives, the surfactant molecules are able to adsorb to the surfaces of an engine fuel system, forming a protective monolayer that reduces friction, wear and tear on internal parts and prevents rust. This is a main contributor to the proven increase in lubricity that IFT additives provide.
This provides lifelong prevention of rust and corrosion in tanks and internal parts, which contributes to longer service life for the engine and parts.
IFT additives are proven to deliver a sizable increase in fuel lubricity and keep the engine running at maximum cleanliness and smoothly, which preserves internal parts. IFT surfactant molecules also create a protective monolayer in the fuel system by adsorbing to all surfaces and serving as a beneficial friction reducer. Less wear and tear on parts and cleaner operation created by IFT additives will significantly extend the life of the engine and parts.
Adsorption is the adhesion of the molecules of a dissolved substance, liquid or gas to a surface. It happens as a consequence of surface energy. In a bulk material, all the bonding requirements of the constituent atoms of the material are filled. However, atoms on the clean surfaces experience a bond deficiency, because they are not wholly surrounded by other like atoms. Thus, it is energetically favorable for them to bond to whatever is available. In the case of IFT additives, the surfactant molecules adsorb to the surfaces of the engine fuel system, effectively creating a protective monolayer.
