It is well known that diesel engine combustion behavior can be improved by improving air/fuel mixture formation. Some improvements have been made by mechanical fixes, such as increased injection pressure, multiple injector orifices and modifications of combustion chamber geometry.
The Viscon inventors have discovered that adding a small amount of a high molecular weight polymer to diesel fuel increases engine power, reduces fuel consumption, reduces engine exhaust temperature and reduces emissions of particulate matter.
Viscon diesel fuel saver improves fuel/air mixture formation by modifying the fuel rather than the engine. A small amount of a high molecular weight polymer is added to the fuel making it viscoelastic.
At best, the fuel behaves like an ordinary liquid. Under conditions of sudden stress, however, as in being sprayed from an injector, the fuel has greatly increased viscosity or solid like elastic properties.
A viscoelastic fuel has different spray and vaporization behavior. The injector spray is more controlled producing more uniform droplet size and more uniform distribution of fuel over the cross section of the spray cone. Super fine, satellite droplets are eliminated and overall Sauter Mean Diameter is reduced. The solid like fuel droplets also resist growth by collision.
The vaporization of viscoelastic fuel droplets is also more controlled. Increased surface tension holds in light end fuel components which would otherwise vaporize, leaving the less volatile components behind.
