A NANO-GRANULE FUEL AND ITS PREPARATION
Technical field
The invention relates to a fuel oil, especially a fuel oil substantially consisting of
nano-granules, and the preparation method for the same.
Background art
The molecules of various conventional fuel oils exist in form of molecule clusters.
Each molecule cluster consists of several dozens to hundred thousands molecules,
forming granules of several dozens to hundreds nanometers in diameter. Such large
clusters make the atomizing of the fuel oil deteriorate. When the fuel oil is burning,
the clusters are hard to combust completely in an instant. Especially under the limited
condition of motor cylinder explosion, the fuel oil is even harder to be burned
completely. Therefore, the thermo-machine efficiency of the fuel oil in the internal-
combustion engine is limited to about 38% or less, and it will generate much thermo-
pollution and chemical pollution.
For long people have been looking for various methods of improving the fuel oil
combustion rate. One type of methods is to add different additives into the fuel oil;
while the other is to use electromagnetic field to treat the fuel oil. The early products
of magnetized fuel savers used both the magnetic field and the static electric field
simultaneously to treat the fuel oil. An example of this is the DJ series fuel savers,
which use two permanent magnets with 1200 Gauss magnetic intensity of south poles.
The south poles are placed opposite to each other with a gap of 2.8-3mm through
which the fuel oil flows. This technical solution applied a static electric field to the
fuel oil at the same time.
China Patent ZL89213344 discloses a magnetized fuel saver. The saver uses two
permanent magnets with the N pole surface's magnetic field intensity of 4300-4600
Gauss and the intrinsic coersivity of 15000-18000 Oersted. The N poles are placed
opposed to each other, leaving a gap of 0.5-1.1 mm and the fuel oil flowing through
the gap to be treated by the magnetic field, This technical solution need not apply any
additional static electric field.
China patent ZL92206719.8 discloses a dual cavity magnetized fuel saver. The
technical solution of this patent employs three cylindrical permanent magnets. One of
the magnets is placed inside of the magnetic filter cavity. It is said that the function of
this magnet is to magnetize the fuel oil and to adsorb the iron magnetic materials in
the fuel. The N poles of the other two magnets face to each other and leave a gap of
0.5-1.1 mm for fuel oil flowing. In one preferred embodiment, the magnet is made of
NF30H material and its intrinsic coersivity is 18,000-20,000 Oersted, with the N pole
face magnetic field intensity of 4,600-5,200 Gauss.

WO 2004/094570 PCT/CN2004/000391
China patent ZL94113646.9 discloses an improved dual cavity magnetized fuel saver.
The configuration of this fuel saver is similar to that disclosed in China patent
ZL92206719.8 mentioned above. What differs is that, magnetic circuit plates are
attached to each back of the two opposite positioned magnets, and also attached to the
back of the magnet in the magnetic filter cavity and the bottom side of the magnetic
filter cavity opposed to the magnet therein. It is said that the existence of the magnetic
circuit plates has reinforced the magnetic field intensity by forming a closed magnetic
circuit in the fuel saver. In addition, the permanent magnet suggested by the patent is
of NF30 material built in cylindrical shape with an intrinsic coersivity of 18,000-
20,000 Oersted and the N pole magnetic field intensity of 4,000-5,200 Gauss. The gap
between the two opposite permanent magnets for the flow of fuel is 0.5-2.0 mm.
Although the above methods of prior art make fuel granules finer, and improve the
fuel combustion to a certain extent, they cannot surely make the fuel oils fine enough
to reach the nano level and improve the fuel combustion thoroughly. In addition, the
small granules resulted from the methods of prior art are not stable. Therefore, these
fuel savers have to be connected to the engines directly, supplying the processed fuel
oil directly to the engines.

greater than 10 nm, preferably no granules greater than 5nm, more preferably no
granules greater than 3 nm.

of molecules through a magnetic field having a air gap magnetic field intensity of at

intersecting with the magnetic force lines.
In the method of present invention, the said magnetic field can be formed by two

intrinsic coersivity greater than 18,000 Oersted at the N pole faces with the same poles

Compared with conventional fuel oils, the nano-granule fuel oil of this invention has
excellent performance and can be extensively applied to all equipment or devices that
burn fuel oil.
Taking the internal-combustion engine as an example, the nano-granule fuel oil of this
invention can be used on internal-combustion engines with different power levels,
including but not limited to motor cycles, automobiles, trucks, high-horse-power
diesel cars, tanks, boats and ships, construction machineries, power generators, and
drilling machineries etc. When applied to internal-combustion engines, compared to
the conventional fuel oil, the nano-granule fuel oil of the present invention exhibits
such advantages as improvement of the fuel utility rate by 20-30%, the car-tail gas
pollution reduced by 50-80%, and possible enhancement of vehicle power, elimination
of carbon deposits, extension of engine service life and reduction of engine noise etc.
For another example, the fuel oil-consuming boilers and the industrial furnaces using
the nano-granule fuel oil of the present invention can save fuel oil by 16.8-20% for the
same thermo effect compared with using conventional fuel oils.
Owing to the fact that the nano-granule fuel oil of the invention can stay in the nano-
granule state for long time, it expands the fuel oil's application range.

Specific Modes of Carrying Out the Invention
Example 1
A device similar to that disclosed in Chinese patent No. 8921334 was used to treat a
conventional fuel oil to produce the nano-granule fuel oil of this invention. However,
both the parameters of the magnets used in this invention and the gap between the
magnets were different from the device in the above patent. See Figure 1 for the
specific configuration.
The device consisted of shell 1, two permanent magnets 2 and 3, stub 4, connection
pipes 5 and 6, and seal rings 9 and 10. Shell 1 had a longitudinal passage. The two
ends of the passage were attached to the connection pipes 5 and 6 through screw-
threads. Shell 1 had a magnetizing cavity in the central part, communicated
perpendicularly to the longitudinal passage. The magnetizing cavity accommodated
two cylindrical permanent magnets 2 and 3. After the two permanent magnets were
installed with the two N poles or the S poles opposite to each other into the
magnetizing cavity, the top of the magnetizing cavity was sealed with the stub 4. The
permanent magnets 2 and 3 were made of N35SH material and have a magnetic field
intensity of about 8,000 Gauss on the N pole faces and an intrinsic coersivity of
22,000 Gauss. The gap between the two magnets for the fuel flow was 0.4mm.
Example 2
A device similar to that disclosed in Chinese patent No. 94113646.9 was used to treat
a conventional fuel oil to produce the nano-granule fuel oil of this invention.
However, both the parameters of the magnets used in this invention and the gap
between the magnets were different from the device in the above patent. See Figure 2
for the specific configuration.
Referring to Figure 2, shell 1 was made of an aluminum alloy by die-casting. Shell 1
has a longitudinal cylindrical passage and inner threads were provided on the inside
walls of the both ends of the passage. In shell 1, a magnetic filter cavity and a
magnetizing cavity were provided. The two cavities were both perpendicular arranged
and communicated to the longitudinal passage cavity of shell 1. The two ends of the
passage were connected hermetically with the connection pipes 13 and 14 through
screw-threads. The connection pipes may be made of an aluminum alloy or brass. The
inside flow passage of the connection pipe had a trumpet shape at one end facing
outward and connected with the body of the present device. The rest part of the
passage of the connection pipe was a straight pipe shape and communicated with the
fuel supplying pipe, carburetor or fuel ejection pump.
The magnetizing cavity was a cylindrical hole, in which were installed two permanent
magnets placed opposite to each other. A gap of 0.45 mm for fuel flow was formed
6

WO 2004/094570 PCT/CN2004/000391
between the permanent magnets 3 and 4. The two north poles (or south poles) of
permanent magnets 3 and 4 were placed opposite to each other. Magnetic circuit plates
were attached to the other end of each of the permanent magnets 3 and 4 in order to
form a closed magnetic circuit.
The magnetic filter cavity was a stepped hole, communicating with the longitudinal
passage of shell 1 and the surface of shell 1. Inside the magnetic filter cavity was
installed a permanent magnet 2. A magnetic circuit plate 6 was attached to one end of
the permanent magnet 2, The other end of the permanent magnetic 2 was opposite to a
magnetic circuit plate 5 attached to the bottom of the magnetic filter cavity. Thus, a
fixed oil flow gap of 3 mm was formed. The magnetic circuit plate 5 was installed in a
concave part of the shell at the bottom of the magnetic filter cavity. It can be fixed
through interference-fitting or industrial adhesive bonding.
The permanent magnets 2, 3 and 4 used there were all of cylindrical structure and
made of N35SH material. The magnets had a diameter of 20 mm and a height of 12
mm. The permanent magnet had a magnetic field intensity of the N pole face of 6,000
Gauss and an intrinsic coersivity of 20,000 Oersted.
The magnetic circuit plates 5, 6, 7, and 8 were of circular plate or cylindrical shape,
with a diameter of 22 mm and a thickness of 5 mm. The magnetic circuit plates can be
made of such magnetic conductive material as pure iron DT4 material or silicon steel
plates.
Example 3
The device similar to that used in Example 2 is used to treat the conventional fuel to
produce the nano-granule fuel oil of this invention. However, both the parameters of
the magnets used in this invention and the gap between the magnets are different from
the device in the above patents and it does not use the magnetic circuit plates.
The magnetic field intensity of the N pole faces of the permanent magnets is 8,000
Gauss and the intrinsic coersivity is 24,000 Oersted. The gap between the two
permanent magnets is about 0.3mm.
The following Examples are intended to demonstrate the physical properties and the
performance of the nano-granule fuel oil of this invention.
Example 4
Small angle neutron scattering technique was used to measure the size of the granules
in the fuel oil of this invention.
The National Institute of Standards and Technology (NIST) of the United States
7

WO 2004/094570 PCT/CN2004/000391
conducted tests on the fuel oil as treated by the device of Example 2 with SANS
technology. Through the comparison of the two samples, one was an ordinary fuel oil,
and the other was the fuel oil treated by the device of Example 2, it was found that the
former contained molecular cluster granules of larger than 300 nm in size while the
size of the granules in the latter was not larger than 3 nm and remained so for at least
one week.
Test method
Small angle neutron scattering (SANS) is an advanced experimental technology to
probe and measure microstructure of materials. It is an especially powerful method for
fluids and soft matters because of the difficulties encountered with these samples by
real space probing techniques such as microscopy. The small angle neutron scattering
technique measures the density distribution or fluctuation in the reciprocal space. But
for most structures, specific information can be obtained about the microstructure of
these samples. It is typically used to measure the granule size, shape and their
distribution in complex fluids such as colloids, polymer solutions, surfactant complex,
and micro-emulsions. The length scales currently available in the world's neutron
laboratories are from 1 nm to 1 jxm using conventional SANS instruments.
Three sets of experiments at NIST Center were performed on different samples using
NG7-SANS instrument. The neutron wavelengths used were 0.60 nm and 0.81 nm,
and the momentum transfer (Q, scattering wave vector) range was from 0.008 nm1 to
1 nm"1, corresponding to length scales from 1 nm to 120 nm.
The fuel oil used as samples was common diesel oil obtained from a Crown Service
Station in Gaithersburg, Maryland, US. The device for treating the fuel oil was a
device of Example 1 provided by the present applicant. Samples were contained in
cylindrical cells when it was tested. The neutron path length was 1 mm, the diameter
of the neutron beam was 12,7 mm, and therefore the sample volume measured was 0.2
ml.
Test results
In the three sets of experiments, the untreated fuel oil samples as obtained were
measured twice within one month. The two measurements were slightly different in Q
range. The results of both measurements similarly shown that the fuel samples
contained molecular clusters of size larger than 300 nm, as shown by one of the curves
indicated as Dl (circle) in Figure 3. As shown in the figure, the curve increases at
low-Q intensity side up to Q=0.008 nm"1. This profile does not necessarily exhibit a
Guinier shape. So the curve shape could not provide the size of the molecule clusters,
because the size is outside and above the up-limit of the size scale measurable by the
instrument. The up-limit of the size scale is the reciprocal of Q-0.008 nm"1, i.e., 120
nm in radius of gyration or 310nm in spherical diameter. But basically it can be
8

WO 2004/094570 PCT/CN2004/000391
determined that these clusters are in quasi-micron size, i.e., 0.5-2 urn.
As for the composition of these clusters, the neutron scattering instrument could not
provide specific information. However it can be definitely concluded that each of such
clusters move as one integral unit. Because of the fact that most molecule structures of
fuel oil are smaller than 10 nm, these clusters can be deemed as molecule clusters or
correlated molecules. Due to the fact that the scattering intensity is directly
proportional to the product of both the quantity of these granules and their "contrast"
with the rest of the fuel, it is hard to calculate either of the quantities.
However, the same fuel samples were treated with the device as described in Example
1 with the fuel going through the device under gravity. The collected samples were
measured twice in a week using the same method as mentioned above with the Q scale
of 0.008 nm"1 results (D4A :squares and D4B: triangles). D4A indicates results of measurement of a
sample of diesel same as Dl freshly processed by the device as described in Example
1. D4B indicates the data of the same sample D4A measured one week later. The two
measurements are similar, but they are markedly different from the results of the
unprocessed fuel, in that they lack the increase of the intensity in low-Q. The
graduation in Figure 3 is by logarithm. The average value of D4A and D4B is 1 cm"1
(the scattering cross sectional area per unit volume), but the intensity of Dl in low-Q
is several times bigger to tens times bigger than that of D4. In fact, the whole curve
can be characterized as flat, indicating that there are no measurable granules in the
measurement range (0.008nm"1 to 0.4m"1). The test was repeated twice and similar
results were obtained, each using the fuel oil freshly-processed by the device in
Example 1.
Conclusions
The SANS measurements show that conventional diesel fuels contain granules of size
larger than 300 nm. However, these granules in the conventional sample disappear
after the fuel sample is treated by the device of Example 1, The size of the granules in
the treated sample is at nanometer level. No detectable granules larger than 3 nm is
present in the processed fuel oil.
Example 5
The physical property changes of the nano granule fuel oil of the present invention as
compared with conventional fuel oil
By conventional methods, T2 and T1 measurements of nuclear magnetic resonance,
viscosity tests and the specific gravity tests were conducted on two diesel fuel samples
before and after flowing through the device as described in Example 1 at different
flow rates, one at l0L/h and the other at 20L/h.
9

WO 2004/094570 PCT/CN2004/000391
The test results are as follows:
1) T2 relaxation time at different time points before and after diesel oil filtration at
two flow rates (see Table 1 and Figure 4);
2) Ti relaxation time at different time points before and after diesel oil filtration at
two flow rates (see Table 1 and Figure 5);
3) Viscosity of diesel oil at various time points before and after the filtration at two
flow rates (see Table 2 and Figure 6); and
4) Specific gravity of diesel oil at various time points before and after the filtration
at two flow rates (see Table 3 and Figure 7).

various time points before and after treatment

Table 3: Measurement results of specific gravity of diesel oil at various time points
before and after treatment

From the above results, it can be seen that the diesel oil has obviously changed its
physical properties after passing through the device as described in Example 1, mainly
including:
1) The T1 and T2 relaxation time of the processed diesel oil is reduced, indicating
that the diesel oil molecules have been polarized by the magnetic field. Figures 1
and 2 show that the restoration process is a periodic one.
2) The viscosity of the processed diesel oil has obviously reduced, with the
maximum reduction magnitude of 22.6% and 14.5% respectively for flow rates of
lOL/h and 20L/h. The viscosity also has a periodic restoration process.
3) The specific gravity of the processed diesel oil has dropped, with a maximum
dropping magnitude of 0.3%. After 24 hours, there is no obvious restoration on
the specific gravity.
