How Was Viscon Developed?
Viscon technology originated in a research program for the Department of
Defense. The objective was to develop compounds that reduce explosion hazards
with jet fuel. Further investigation revealed Viscon greatly improved combustion
and reduced engine temperatures.
-
What makes Viscon unique?
The Viscon fuel additive is used to improve air/fuel mixture preparation which
is normally addressed by engineers modifying engine hardware. Viscon’s
technology modifies the fuel’s physical properties, rather than fuel chemistry.
The inventors of Viscon discovered that diesel fuel’s physical behavior stands
in the way of optimizing air/fuel mixture in diesel engines and devised a way to
modify the behavior.
-
No. The active ingredient of Viscon is a food-grade polymer used in products
like chewing gum. It is not miscible in water and will not contaminate our
groundwater. Viscon is a pure hydrocarbon and is thus exempt from EPA fuel
additive registration.
-
Total treatment costs should be on the order of pennies per gallon of fuel
treated. When you add other positive aspects such as extended engine life,
reduced overall maintenance costs and better fuel mileage, the cost of treatment
will be substantially reduced.
-
Will Viscon Improve Mileage?
Ninety-five percent of the vehicles using Viscon improve their mileage. Some
temporary reductions may occur while the engine computer adjusts the air/fuel
ratio. Since Viscon is a powerful cleaning agent, mileage and performance will
continue to improve as deposits are eliminated from the engine.
-
How does Viscon effect engine timing?
Viscon will widen the tuning tolerance of any engine. Viscon has been
demonstrated to allow increased spark advance before knock. Therefore, a small
advance in spark can be used to improve mechanical efficiency of your engine.
-
What is Viscon’s production capacity?
8,085 gallons of Viscon per day. Sufficient to treat 20,697,600 gallons of
diesel per day.
-
Will Viscon improve the cetane/octane rating of fuel?
The octane number of a fuel denotes its ability to resist pre-ignition
combustion. Combustion gas temperature has a direct relationship on an engine’s
cetane/octane requirement. Viscon reduces combustion gas temperature and reduces
the engine’s cetane/octane requirement.
-
Could Viscon Be Substituted For MTBE?
Small additions of Viscon to the fuel provide considerable additional horsepower
and torque while the efficiency of burn improves. It is a far superior
alternative to MTBE and it will not contaminate our ground water.
-
Viscon is a pure hydrocarbon, and as such is exempt from EPA regulations. In
accordance with the EPA registration requirements for fuels and fuel additives,
“‘additive’ means any substance other than one composed solely of carbon and/or
hydrogen.”
-
Why does my automobile start more easily when I use Viscon?
Cold starts are complicated by the reduced vaporization of fuel in a cold
engine. The result is insufficient fuel in the cylinder to support proper
combustion. During cold starts, a considerable percentage of fuel wets intake
and cylinder walls. By reducing wall wetting through the viscoelastic properties
it imparts on fuel, Viscon improves the mixing of fuel with air which in turn
improves engine starting.
-
How does Viscon effect spray patterns?
Viscon reduces the Sauter mean volume diameter of sprayed fuel. It also makes
droplet size distribution across an injector spray cone more uniform. Finally,
Viscon causes the mass of fuel to be more evenly distributed across the spray
cone.
-
Why does Viscon decrease engine vibrations?
Cycle-to-cycle combustion variability causes most engine vibrations. By
improving the air/fuel mixing, variations in the quantity of fuel and efficiency
of in-cylinder burns decrease. Viscon improves the uniformity of the air/fuel
mixture thus causing less erratic combustion that causes most engine vibrations.
-
What are the long-term effects of using Viscon in my engine?
Viscon does not cause either short term or long term harm to gasoline or diesel
engines. Viscon is a pure hydrocarbon. The active ingredient, a long-chain
hydrocarbon, burns into a gas and leaves no residue. The polymer in Viscon has
been used in gasoline and diesel fuel in a shorter molecular form for more than
fifty years.
-
Why does Viscon improve torque?
Viscon improves both the volumetric efficiency of an engine, and the uniformity
of fuel species distribution in the cylinder at ignition and during burn. It is
well known that increased volumetric efficiency increases torque. Less well
known is that a more uniform distribution of the light and heavy ends of fuel in
the mixture at ignition and during burn increases the speed of flame
propagation. The result is better conversion of the fuels energy to mechanical
energy and increased torque.
-
What is the technology behind Viscon?
Viscon is a spin off of work to make an aircraft fuel that would not explode
when a fuel tank is hit by a projectile or when an airplane fuel tank is
ruptured in a crash. It was discovered at that time that addition of a high
molecular weight polymer to jet fuel eliminated the black cloud of smoke
associated with ignition of misted jet fuel in a crash. Follow on work
demonstrated that the polymer changed the physical properties of a sprayed fuel,
improving the uniformity of droplet size and distribution, and modifying its
vaporization behavior.
-
Why does Viscon decrease visible smoke in the exhaust of my engine?
Smoke is generally a sign of incomplete combustion of the fuel (unburned
hydrocarbons). Viscon causes fuel to burn more completely in two and four cycle
gasoline and diesel engines reducing the amount of unburned hydrocarbons in the
exhaust.
-
Will Viscon damage paint?
Viscon does not contain any caustic chemicals, and therefore will not damage
paint.
-
What happens if I put too much Viscon in my fuel?
Putting more than twice the recommended amount of Viscon in your fuel may negate
the effects of Viscon. This dosage will not harm your engine, but you may not
see any benefits. Too much Viscon in fuel negates the effect of extensional
viscosity in fuel.
-
Will Viscon damage my catalytic converter?
No. Most catalytic converters suffer damage when they are overheated or are
subjected to chemicals that bind with and neutralize their catalysts. Since
Viscon is a 100% hydrocarbon, and therefore, does not introduce any harmful
chemicals to a catalytic converter.
-
Does Viscon work as well in an engine with a carburetor as one with a
fuel injector?
Yes. Viscon will work just as well in both.
-
Will Viscon effect the oxygen sensor in my car?
In some cars, the oxygen sensor, which feeds back to the engine control module,
will cause the engine to idle higher. After about a tank of fuel, the injection
system will recalibrate itself and idle as it was without Viscon.
-
Is Viscon safe for use in diesel engines?
Viscon is a formulation of pure hydrocarbons which is completely compatible with
diesel fuel systems and diesel engines. A different form of the active
ingredient in Viscon has been used in diesel fuel for more than fifty years.
-
Why does Viscon work in diesel as well as gasoline?
The efficiency of combustion in both diesel and gasoline engines is controlled
by the properties of the air/fuel mixture in the cylinder at the time of
ignition and during burn. In both engines the physical behavior of the fuel
following injection effects the uniformity of the air/fuel mixture. By modifying
a fuel's physical properties Viscon makes diesel and gasoline air/fuel mixtures
more uniform, improving combustion efficiency in both.
