Background of the invention and related prior Art
Fuel oils can be divided into two primary classifications, i.e., distillate fuel oils,
and residual fuel oils. Distillate oils are composed entirely of material
vaporized in refinery distillation towers; consequently, they are clean and free
of sediments, relatively low in viscosity, and they contain no inorganic ash.
Residual fuel oils, however, contain fractions that cannot be readily vaporized
by heating. These fractions are black and viscous, and they include any organic
ash components originally present in the crude. In some cases, the whole crude
itself is used as a residual fuel.

Distillate fuel oils, being low in sulfur, free of ash, and relatively easy to
handle, are used in applications where such qualities are more important than
fuel prices, for example, in home heating. However, where cost is an important
consideration, and large volumes of fuel are required, for instance, in electric
power generation, in producing industrial steam, for process heating and the
like, residual oils are usually employed as the fuels of choice. The single largest
source of energy of energy in India after coal is petroleum. About two-third of
which is imported. The petroleum derived fuel, i.e. motor gasoline and diesel
are being used almost by the entire road transport vehicles. The diesel fuel is
also being used in agriculture operations. The high dependence on important
outside source of energy is an issue related to energy security of the country. In
the recent time, the combustion of these fossil fuels has been recognized as a
major cause of air pollution in Indian cities.

A herbal composition as stated in document J. KISHORE KUMAR et al (2016
describes Pollution from the petroleum oil is increasing day by day in terms of
C02, CO, NOX, and many other gases and particles. Price difference and
economy leads people toward the use of alternative fuels. To overcome this
problem turpentine oil is mixed with petrol and diesel and taken as different
samples. Then the properties like flash point, fire point, cloud and pour point,
calorific value, carbon content test, ash content test, copper corrosion test are
analyzed at various proportions of turpentine oil (5%, 10%, 15%, 20% of 100
ml sample) blended with petrol and Diesel fuels. Any other type of substance,

can be assigned some physical and chemical properties (e.g. density, thermal
capacity, vapour pressure, chemical formula, etc). However, most of the times,
combustion properties are also assigned to blended fuels, in spite of the fact
that these properties depend on the oxidizer (e.g. air, pure oxygen) and the
actual process (e.g. the explosion limits depend on the boundary conditions for
a given fuel/oxidizer pair). Fuel price, availability, risk, and so on, could also
be considered fuel properties (attributes).
This invention of the document Phan et al. (2008) relates to the Alkali-
catalyzed transesterification of waste cooking oils, collected within Ho Chi
Minh City, Vietnam, with methanol was carried out in a laboratory scale
reactor. The effects of methanol/waste cooking oils ratio, is on potassium
hydroxide concentration and temperature.
Curran et al., (2001) describes IZmission standards for diesel engines in
vehicles have been steadily reduced in recent years, and a great deal of research
and development effort has been focused on reducing particulate and nitrogen
oxide emissions. One promising approach to reducing emissions involves the
addition of oxygen to the fuel, generally by adding an oxygenated compound to
the normal diesel fuel. Miyamoto et al. showed experimentally that particulate
levels can be significantly reduced by adding oxygenated species to the fuel.
They found the Bosch smoke number (a measure of the particulate or soot
levels in diesel exhaust) falls from about 55% for conventional diesel fuel to
less than 1% when the oxygen content of the fuel is above about 25% by mass,

Current theories and models have been quite successful in understanding the
reaction paths for the early % of this process, namely the cyclization of the
smaller fragments into aromatic hydrocarbons with one, two and three rings.
The subsequent production of real soot remains a subject for continued study.
The present model indicates that when significant fractions of diesel fuel are
replaced by oxygenated species, the carbon atoms already bonded to oxygen
atoms cannot provide soot precursors, and this process is responsible for the
observed results. Since the fractions of oxygenates required to completely
eliminate soot precursor production are so large, approaching 75-80%, it is
probably unrealistic to attempt this degree of fuel modification in actual diesel
engine practice, but the insights into the processes leading to soot provided by
the model, supported by the excellent qualitative agreement between
experimental and model results, can be very valuable in future studies of diesel
combustion chemistry..
The invention stated in the document US20080005957, describes a biodiesel
handling and blending system using varying parameters of biodiesel/distillate
blend ratio, temperature, and amount of mixing occurring in the batch, to obtain
positive results. The results showed that when zero (0) degree petroleum
distillate was blended with fifty (50) degree biodiesel, and thoroughly mixed;
the resulting homogeneous blend did not contain wax crystals. The results also
showed that once the biodiesel had been distributed homogeneously throughout

the sample, the resulting mixture exhibited properties more like a petroleum
distillate than like a methyl ester.
The document US5820640 states a novel diesel engine fuel is in the form of a
pyrolysis liquid-in-diesel oil microemulsion fuel comprising: (a) diesel oil in an
amount sufficient to form a continuous phase in the composition; (b) a
pyrolysis liquid forming a discontinuous phase in the composition, this
pyrolysis liquid being a liquid obtained by rapid pyrolysis of biomass; and (c)

between 4 and 18, derived from fatty acids and polyoxyethylene glycol, or fatty
acids, sorbitol and polyoxyethylene or polyethoxylated alcohols with long
aliphatic chains. This fuel has excellent stability and physical properties similar
to those of regular diesel fuel.

Still other object of the present invention to provide the fuel additive

The object of the present invention is to provide a fuel additive composition

The control of emission from internal combustion engines has received
substantially continuous attention worldwide for many years attempting
reduction of emission of carbon monoxide (CO), Nitrogen oxides (NOx),
unburnt hydrocarbons (HC), and other pollutants like P.M. (particulate matter)
from the combustion of fuels but generally have met with limited success.
It is accordingly the fuel additive composition which when added to diesel fuel,
will provide clean and more efficient combustion in internal combustion
engines thereby reducing pollution and increasing mileage and to provide a
multifunctional fuel additive which will not have any harmful effect over
engines.
The fuel additive also provide fully miscible with any other additive (like
biodiesel, alcohol etc.) if present in the diesel fuel.
On additive which on mixing with the diesel fuel in proper ratio will improve
the diesel fuel with increase in efficiency by 10 - 16 % and reducing emission
pollution by 40 - 50 %.
The improved diesel fuel composition which has the capability of reducing
polluting emission substantially and will reduce fuel cost which is much more
than the cost of the additive.
The fuel additive which is easily applicable, highly economic as it reduces fuel
expenditure by at least 10 - 16 % depending on the engine HP, Torque and
other factors like engine condition, age, load etc. As the additive helps to burn

the fuel more efficiently, better combustion naturally creates less emission and
increases mileage. According to the concept the fuel additive particularly
reduces carbon monoxide (CO), Hydro Carbon (HC) and unburnt carbon
emission (particulate matter / Smoke).
The fuel additive composition is formulated to contain aliphatic hydrocarbon of
carbon range C8 - C20, Mineral Turpentine Oil, Alkylene glycol esters, Alkyl
ester, Liquid Nonionic surfactant, cetane improver like 2 ethyl hexyl nitrate,
Oxygenates like Tert. Amyl Ethyl Ether, and synergistic compounds like
Mesitylene and p-Xylene.
The cetane improver reduces the ignition delay where mineral turpentine oil
appear to improve ignition efficiency of the fuel. Alkylene glycol ester along
with Butyl recinoleate help to lubricate the upper portion of the cylinders as
well as in combination with non-ionic surfactant disperse water contained in
the fuel system so as not to interfere with the complete combustion of the fuel
system. Tert amyl ethyl ether acts as oxygenate whereas Mesitylene and p-
Xylene provide synergistic effect.
The total concentrated mixture is then diluted with proper succussion with BS
VI diesel in the ratio 1:100 for use as the final additive which again
dramatically increases the efficiency of the engine and fuel duly observed with
prolonged experimentation as noted below with the following dosage:-
4 ml /10 litre of diesel fuel for use in engines up to 100 HP
5 ml /10 litre of diesel fuel for use in engines over 100 HP

It is now a known fact that presence of sulphur in Diesel, although a source of
emission pollutant like SOx; also can impact substantial lubricity to engines.
So, lower sulphur concentrations as stipulated in BSVI (Equivalent to Euro VI)
specification has lower lubricity effect. This multifunctional Diesel additive has
shown to improve the lubricity notably when tested using High Frequency
Reciprocating Rig (HFRR) method. Several experimentation of the Diesel
additive in very old passenger buses (which travelled more than 500 thousand
kilometers) showed drastic cut in emission pollution through engine exhaust by
more than 65 - 70 % particularly in terms of CO & HC emissions.
Experimentation of the Diesel additive is SUV & Buses including Volvo buses,
High capacity Diesel Generator. (750 KV) show savings of fuel by about 10 -
16 % by volume.
When mixed with Diesel (commercially available in petrol Pumps), it has
shown remarkable increase in Cetane No, Cetane Index , improved CFPP, pour
point etc. thus establishing that the Diesel fuel quality is improved & did not
have any adverse effect on its original quality.
The fuel additive composition of the present invention is formulated to include
as one component thereof Diesel BS VI, as a mediator to mix properly with
Diesel in the second stage as the additive is solely meant for Diesel fuel.
Another component used in the fuel additive composition is Mineral Turpentine
oil, which is an aliphatic hydrocarbon in the range (C7 - C12) and having
boiling range (150°C - 200°C)is believed to help at least in part the initial
ignition of the Diesel fuel.

One cetane improver 2 - ethyl hexyl nitrate having molecular formula
(C8H17NO3) has been used to boost the cetane no. For improved cetane no
ignition delay time is drastically reduced providing much better combustion,
automatically effecting reduction of emission
is used as a
generating supply
Another component tert amyl Ethyl Ether
fuel oxygenate which helps in combustion
of oxygen.
Another compound a nonionic surfactant, Nonyl Phenol poly
ethoxylate (C9H19C6H4(OCH2CH2)nOH) is used where it is
believed that surfactant and the ether (acting as a coupling
agent) cooperate each other to minimize the effect of water
contained in the diesel fuel during the combustion process.
Such surfactants are commercially available in the market as
NPEO 4.5, NPEO 9.5 etc.
Other two compounds Diethylene glycol laurate and Butyl recinoleate are used
in the fuel additive having formula (C16H32O4) & (C22H42O3) specifically have
both surfactant effect as well as lubricating effect on the upper part of the
cylinder. Both laurate and Recinoleate % having lubricating property, provide
the required upper cylinder lubrication and controlled oxidation.
Two other compounds p-Xylene and Mesitylene are used for synergistic effect
which not limiting to theory are believed to provide miraculous effect in
combination with the other chemicals.
In general the composition of the present invention is somewhat sensitive to
variation in the amount. In general the aliphatic hydrocarbon having higher
carbon chain may vary from 15-25 % by volume whereas Mineral Turpentine
oil having lower carbon chain also may vary from 15-30 % by vol. (surfactant
Nonyl phenol ethoxylate will vary from 3 - 10 % by volume, 2 - Ethylhexyl
nitrate is used between 10- 30 % by vol. followed by tert amyl ethyl ether
between 3 - 7 % by vol. Then Di-ethylene Glycol laurate between 5 - 15 % by

vol. and Butyl Recinoleate 3 - 8 % by vol. are mixed. Finally p-Xylene
between 3-7 % by vol. & Mesitylene 5 - 15 % by vol. are mixed for synergistic
effect.
Finally after mixing the components in the most conventional technique, the
concentrate mother additive is diluted with proper succussion with BS VI
equivalent to Euro VI diesel.
Though in precise manner how the diluted and agitated components function in
combination is fully not understood at the present time, yet it has been observed
that the diluted mixture after proper succussion in the expert way which
dramatically improves the property of the additive. This procedure of mixing
using succussion probably resembles the well known potentisation process.
The additive when mixed in the ratio mentioned before with diesel fuel initiates
internal combustion of the engine increasing its efficiency and reducing
pollution enormously.
Different combinations have been tried which are illustrated by the following
examples.
However, this should not be construed to limit the scope of the present
invention. The present invention is illustrated by the following examples, which
is not intended to limit the effective scope of the invention. Out of five
