(54) FUEL FEED APPARATUS FOR AN INTERNAL
COMBUSTION ENGINE
(71) We, TORAY INDUSTRIES
INC. a Japanese company of 2, Nihonbashi
Muromachi 2-chome, Chuo-ku, Tokyo, 103
Japan, do hereby declare the invention for which we pray that a patent be granted to us and the method by which it is to be performed be particularly described in and by the following statement:- The present invention relates to an apparatus for feeding fuel to an internal combustion engine. More particularly, the present invention relates to an apparatus for uniformly mixing and dispersing each component of a fuel oil consisting of a plurality of components and thereafter feeding said fuel oil to the combustion chamber of an internal combustion engine.
It has been known to use a so-called emulsified fuel obtained by adding and dispersing water or an aqueous methanol solution to and in gasoline, gas oil, kerosene or heavy oil as a fuel for an internal combustion engine. It has been found that this emulsified fuel is effective for reducing the amounts of NOX and smoke in the engine exhaust, and for improving the thermal efficiency of the fuel.
When an emulsified fuel is obtained by mixing water or an aqueous methanol solution with a fuel oil and emulsifying the resultant mixture, and is injected as a mist into a combustion chamber in an internal combustion engine at a high temperature, the temperature of the injected misty fuel momentarily reaches the evaporation temperature of the fuel oil. In the process of this elevation of temperature, the temperature of the water which is present in the fuel as superfine particles reaches the boiling point of water and the water boils in the fuel mist. As a result, the water in the fuel explosively boils. ;1.verizing the fuel mist to form extremely superfine particles and promoting the evaporation of the fuel oil.Because of this phenomenon the fuel substantially completely burns in the combustion chamber with resultant decrease of the amount of NOX in the exhaust, and improvement of thermal efficiency of the engine.
Emulsified fuels having such excellent combustion characteristics have not been put to practical use to date. Fuels mixed with mutually incompatible water or with an aqueous methanol solution and emulsified tend to undergo phase separation as time goes by. And even when the two components do not undergo phase separation, particles of water, etc. mixed with the fuel oil tend to flocculate and become coarse. Because of this, the excellent characteristics possessed by a true emulsion fuel are sharply reduced. Further, the phase-separated substance such as water corrodes or blocks engine parts having small passages, such as fuel injection nozzles, making maintenance troublesome.
In order to prevent such phase-separation of the two components, and to prevent the water particles from becoming coarse, it is necessary to attain superfine sub-division of the water or of the aqueous methanol solution in the fuel oil.
Emulsification of conventional emulsified fuel is carried out by an agitator or an ultrasonic vibrator. Preparation of such conventional emulsion fuel has drawbacks in that it requires the provision of large and complicated power sources, and because these power sources and mixing devices must be incorporated in a sealed or semisealed system. It has the further disadvantage that adequate subdivision of particles is difficult to obtain.
The present invention provides an apparatus for feeding a fuel consisting of a plurality of components to an internal combustion engine comprising:
a fuel tank for storing the fuel;
a circulating pump for circulating the fuel,
a motionless mixer for uniformly mixing the fuel components, said fuel tank, said circulating pump and said motionless mixer being connected with each other in series through a circulating conduit to form a circulating circuit,
a connection to said circulating circuit, communicating with a fuel feed conduit, said fuel feed conduit communicating with a fuel injection pump and a fuel injection nozzle.
Referring to the accompanying drawings:
Figure 1 is a block diagram showing a conventional apparatus for feeding a fuel oil (not mixed with any mixing components) to the combustion chamber of an internal combustion engine;
Figures 2 to 7 are block diagrams illustrating various embodiments according to the present invention;
Figure 8 is a plan view showing one embodiment of a motionless mixer used in the present invention;
Figure 9 is a longitudinal view taken along the line L-L' which appears in Figure 8;
Figures 10 and 11 are block diagrams showing other embodiments according to the present invention;
Figure 12 is a graph showing the smoke density, brake specific fuel consumption (BSFC), and NOX concentration obtained for various ratios of water-to-gas oil in emulsions prepared according to this invention.
In Figure 1, the apparatus for feeding a fuel to an internal combustion engine includes a fuel tank 1, a fuel feed pump 4, a first filter 5, an injection pump 6, a second filter 7 and an injection nozzle 8 which are connected to each other in series through a conduit 3. In the fuel tank 1 is stored a fuel oil 2, which fuel oil 2 is adapted to be injected from the tip of the injection nozzle 8 into a combution chamber 10 provided inside a cylinder 9.
Two return pipes 3' are connected to the first filter 5 and the injection nozzle 8, respectively. Excess fuel oil fed to the first filter 5 and the injection nozzle 8 is returned to the fuel tank 1 through pipes 3'.
The apparatus shown in Figure 1 is applicable to a fuel in which at least two compatible components are mixed or dissolved. However, when using an emulsified fuel consisting of more than two incompatible components the apparatus is not satisfactory because the respective components of the fuel oil undergo phase separation upon aging.
The apparatus shown in Figure 2 according to the invention is made for an emulsified fuel which is adapted to be mixed and emulsified with a plurality of mutually incompatible components. It has a circulating circuit 19 consisting of a fuel tank 1, a circulating pump 15 and a motionless mixer 16 connected in a series and back to tank 1 through a circulating conduit 18. Between the fuel tank 1 and the motionless mixer 16 in this circulating circuit 19, a fuel feed conduit 3 is connected at connection 20.
A mixed fuel 2 of fuel oil and water, or fuel oil and an aqueous methanol solution, stored in the fuel tank 1, circulates continuously in the circulating circuit 19 by the action of the circulating pump 15. While circulating, the fuel 2 repeatedly passes through the motionless mixer 16, which repeatedly promotes mixing, and the fuel 2 is formed into superfine emulsion particles.
While repeating this mixing operation during circulation, part of the fuel 2 flows to the fuel feed conduit 3. The amount of fuel circulating in the circulating circuit 19 should always be greater than the amount of fuel flowing to the conduit 3. The flow rate of the fuel inside the circulating circuit 19 is so set up as to be greater than the flow rate of the fuel inside the conduit 3. The emulsified fuel after branching is injected as a mist into the combustion chamber 10 from an injection nozzle 8 via a fuel feed pump 4, a first filter 5, an injection pump 6 and a second filter 7. The circulating pump 15 is driven through a clutch 14 by a power shaft 13 rotated by a piston 11 and a connecting rod 12 of the internal combustion engine, the mechanical parts being conventional per se, and being shown diagrammatically in
Figure 2.
Because the circulating pump 15 functions continuously, mutually incompatible multiple fuel oil components are capable of being adequately emulsified without any phase separation, and then forwarded to the combustion chamber, even if they have undergone phase separation in the fuel tank 1. Because a motionless mixer 16 is provided in the circulating circuit 19, the apparatus of the present invention can be made simpler in structure and smaller in size as compared to conventional emulsifying apparatus which utilizes an agitator or an ultrasonic vibrator.
When the circulating pump 15 is continuously driven, the fuel oil per se is elevated in temperature. Therefore, a radiator 17 may be provided anywhere in the circulating circuit 19. If necessary, the circulating pump 15 can be operated intermittently by manipulating the clutch 14. This manipulation may be carried out either manually or automatically by a timer, using a cycle which does not reduce the highly mixed condition of the fuel components: The clutch may be manipulated in response to a detecting signal which detects the fuel temperature in the circulating circuit 19.
The apparatus shown in Figure 3 locates the connection 20 between the circulating pump 15 and the motionless mixer 16, the fuel feed conduit 3 being connected to the fuel feed pump 4 and forwarded as previously described. In Figure 3, the circulating pump 15 is driven through a dynamo 22 which is driven by a power shaft 13 of the internal combustion engine.
Reference numeral 14' designates a control switch.
The apparatus shown in Figure 4 locates the connection 20 between the circulating pump 15 and the fuel tank 1. The circulating pump 15 may be driven by either of the means shown in Figures 2 and 3, or by other means.
The apparatus shown in Figure 5 locates the connection 20 directly at the fuel tank 1.
The apparatus shown in Figure 6 is the same as that of Figure 2, in that the connection 20 is located between the fuel tank 1 and the motionless mixer 16.
However, it does not provide any fuel feed pump 4 independently. The circulating pump 15 also performs the function of the fuel feed pump 4.
The apparatus shown in Figure 7 is the same in structure as that of Figure 6 in that the connection 20 is provided between the fuel tank 1 and the motionless mixer 16 and the circulating pump 15 serves also as the fuel feed pump 4. However, it provides the connection 20 at the first filter 5. A conduit 18' serves the functions of both one of the return pipes 3' and the conduit 18 as a part of the circulating circuit 19.
The radiator 17 is mounted on this conduit 18' to limit or prevent elevation of temperature of the fuel 2 owing to circulation. The circulating pump 15 is driven by any means, such as those shown in
Figures 2 and 3.
As shown in Figures 2 to 7 the apparatus for feeding fuel according to the present invention is so adapted that the fuel oil in the fuel tank is uniformly mixed in the circulating circuit from which a part of the fuel oil is taken out and fed to the combustion chamber. Therefore, the fuel does not undergo phase separation by the time it reaches the combustion chamber, and accordingly an added substance such as water does not separate at the surface of the fuel injection pump or the fuel injection nozzle. Therefore, corrosion or blockage of the injection pump or the injection nozzle does not occur.
The motionless mixer used in the present invention is of a type having ability to finely divide more than two different fluids solely by causing the fluids to pass through the interior thereof. Although the mixer per se has no mobile parts, and consists of members that are all static. it has the function of an agitator promoting fluid mixing. The motionless mixer described in
U.S. Patent 4,050,674 is an excellent example, and is preferable in the practice of this invention.
The motionless mixer shown in Figures 8 and 9 is of the type disclosed in U.S. Patent 4,050,674. It has a unitary structure 25 consisting of a pair of passages 24, 24' having interior vanes 23, 23' and a collecting and dividing chamber 26 connected to the pair of passages 24, 24'. The unit 25 includes a plurality of passages similar to passages 24 and 24' connected to dividing chambers 26 and arranged so that a plane passing through the axes of each pair of passages 24 and 24' is perpendicular to the plane passing through the axes of the next pair of passages.
In such motionless mixer as mentioned above, the number of passages is designated
N and the number of elements is designated m. When two unlike liquids are passed simultaneously through this motionless mixer, the number of divisions in the liquids
P may be shown as:
P=(2N)"
The mixing of the liquids passing through the motionless mixer increases, with the number of divisions and in proportion to the number of the elements provided.
When two unlike liquids repeatedly pass through the motionless mixer m times, the P becomes:
P=(2N)mn
Other known mixers, such as those disclosed in U.S. Patents Nos. 3,286,992 and 3,860,217, for example, may be used.
Figure 10 shows another embodiment of the apparatus according to the present invention. This apparatus has another fuel tank 28 aside from the fuel tank 1 shown in
Figures 2 to 7. This fuel tank 28 contains a fuel 29 without any added components. Said apparatus is so constituted that a fuel 29 in the fuel tank 28 is fed to the combustion chamber 10 aside from the emulsified fuel derived from the circulating circuit 19.
Namely, in Figure 10, a switch valve 31 is provided between the connection 20 and the fuel feed pump 4, which switch valve 31 is connected to the fuel tank 28 through a conduit 30. The manipulation of the switch valve 31 may be carried out manually or automatically. The switching of the switch valve may also be carried out by a timer or a valve transfer device which is operated, for example, by a signal responsive to the temperature detected from cylinder 9 of the internal combustion engine.
In the apparatus shown in Figure 11, the switch valve 31 is provided between the second filter 7 and the injection nozzle 8 and the fuel tank 28 is connected to the switch valve 31 via a fuel feed pump 4', a first filter 5', an injection pump 6' and a second filter 7' through the conduit 30. The manipulation of the switch valve 31 may be carried out by the same means as referred to in connection with Figure 10.
In general, when an emulsified fuel is used, engine starting under cold conditions is difficult. To solve this problem, the fuel tank selection may be shifted from 1 to 28 by manipulating the switch valve 31 at any desired time, so as to feed the fuel 29 to the conduit, injection pump, filter and etc. for the starting of the engine. This conversion 'may be made upon stopping of the engine, for example.
It is advantageous that a fuel consisting of a plurality of incompatible components may be continuously maintained in a satisfactory mixed condition. This is effected by the circulating circuit in the apparatus; the apparatus according to the present invention is effective for reducing the NOX percentage in the exhaust and for improving the thermal efficiency of the engine. No difficulty is encountered during use.
Also, the mixing and emulsification of the unlike components may be carried out under conditions appropriate to the composition of the fuel oil used. As compared to conventional means, the power loss during operation is significantly reduced.
Further, because the feed of the fuel oil to the injection structure is carried out after the fuel oil has been completely emulsified, the primary parts of the injection structure are not corroded.
EXAMPLE
Several fuel mixtures were made according to the following steps:
(1) lV0 weight of Ionet N-2 of HLB=6 (Sanyo Kasei Co., Ltd.) was added to gas oil and then stirred.
(2) Various amounts of water were added to said mixture, and stirred again. Several different fuel mixtures were thus obtained.
Each of the fuel mixtures above obtained was put into the fuel tank 1 in Figure 2, respectively. Using the apparatus fuel tank 1
in Figure 2, each of these mixtures was circulated in the circulating circuit 19 at a delivery pressure of 1.5 KgJcm2 and at a flow rate of 1.0 m/sec.
While in circulation, a part of the
emulsified fuel was diverted through the connectio? 20, fed to the injection nozzle 8,
and injected to the combustion chamber
from the injection nozzle 8.
As a result of the above mentioned tests, there was obtained the results appearing in
Figure 12 which showed the smoke density, the brake specific fuel consumption (BSFC) and the NOX concentration for various ratios of water-to-gas oil in the fuel emulsion.
Combustion tests of the emulsified fuels obtained above were made under the conditions of the brake mean effective pressure (BMEP) of 5.31 Kg./cm2 and an injection timing of 11.3 , 16.7 and 21.7 cA (crank angle) respectively.
From Figure 12, it can be seen that the NOX concentration, the smoke density, and the specific fuel consumption decreased with increased ratio of water-to-gas oil.
