Description
- The disclosure of Japanese Patent Application No. 2003-382992 filed on Nov. 12, 2003, including the specification, drawings, and abstract is incorporated herein by reference in its entirety.
- 1. Field of the Invention
- The invention relates to a fuel reforming apparatus for reforming a mixture of fuel and gas containing oxygen.
- 2. Description of the Related Art
- An internal combustion engine is known, in which a fuel reforming apparatus including a reforming catalyst is provided, and a fuel component obtained by reforming various types of fuel using the fuel reforming apparatus is burned in a combustion chamber, whereby stable combustion is obtained, and amounts of HC and NOx in exhaust gas are reduced (for example, refer to Japanese Patent Laid-Open Publication No. 2001-241365 (JP-A-2001-241365)). A typical fuel reforming apparatus that can be applied to such an internal combustion engine includes a reforming catalyst for reforming a mixture of fuel and air, and a mixing chamber that is provided upstream of the reforming catalyst (for example, refer to Japanese Patent Laid-Open Publication No. 2001-227419 (JP-A-2001-227419)). A fuel injection valve for supplying fuel into the mixing chamber, and an air supply pipe for supplying air into the mixing chamber are connected to the mixing chamber. Also, a fuel injection apparatus is known, in which a swirl flow of air can be generated around fuel injected from a nozzle hole of a nozzle for injecting fuel so that atomization of fuel and mixing of fuel and air can be promoted (for example, refer to Japanese Utility Model Laid-Open Publication No.5-57356 (JP-U-5-57356)).
- However, in the aforementioned fuel reforming apparatus, there is a possibility that the fuel and the air that are supplied into the mixing chamber are not mixed uniformly, and the concentration of the mixture that flows from the mixing chamber into the reforming reaction chamber becomes non-uniform. Therefore, it is not easy to allow a reforming reaction in the reforming reaction chamber to proceed efficiently so as to obtain desired reforming efficiency.
- It is an object of the invention to provide a fuel reforming apparatus which allows fuel and gas containing oxygen to be mixed with each other uniformly, and which has high reforming efficiency.
- A first aspect of the invention relates to a fuel reforming apparatus for reforming a mixture of fuel and gas containing oxygen. The fuel reforming apparatus include a mixing chamber into which fuel and gas containing oxygen are supplied, and a reforming reaction chamber which is provided downstream of the mixing chamber, and which includes a reforming catalyst for reforming the mixture. Further, a cross sectional area of an outlet of the mixing chamber is smaller than a cross sectional area of an inlet of the reforming reaction chamber.
- In the fuel reforming apparatus, the fuel and the gas containing oxygen are supplied into the mixing chamber having the outlet whose cross sectional area is smaller than the cross sectional area of the inlet of the reforming reaction chamber in such a manner that the fuel and the gas containing oxygen are mixed with each other. With the configuration, the fuel is atomized efficiently in the mixing chamber in which a flow rate is increased, and the fuel reliably contacts the gas containing oxygen in the mixing chamber. Accordingly, in the fuel reforming apparatus, the fuel and the gas containing oxygen can be mixed with each other uniformly. Thus, it is possible to allow the reforming reaction in the reforming reaction chamber to proceed efficiently, and to obtain high reforming efficiency.
- A second aspect of the invention relates to a fuel reforming apparatus for reforming a mixture of fuel and gas containing oxygen. The fuel reforming apparatus include a mixing chamber; fuel supply means for supplying fuel to the mixing chamber; gas supply means for supplying gas containing oxygen to the mixing chamber; and a reforming reaction chamber which is provided downstream of the mixing chamber, and which includes a reforming catalyst for reforming the mixture. Further, a cross sectional area of an outlet of the mixing chamber is smaller than a cross sectional area of an inlet of the reforming reaction chamber.
- The gas containing oxygen may be air or exhaust gas.
- The foregoing and further objects, features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the accompanying drawings, wherein like numerals are used to represent like elements and wherein:
-
FIG. 1 is a schematic diagram showing a configuration of a fuel reforming apparatus according to an embodiment of the invention; -
FIG. 2 is an enlarged partial cross sectional view showing a main portion of the fuel reforming apparatus shown inFIG. 1 ; -
FIG. 3 is a cross sectional view showing a nozzle member included in the fuel reforming apparatus shown inFIG. 1 ; and -
FIG. 4 is a partial cross sectional view showing a fuel reforming apparatus according to another embodiment of the invention. - Hereinafter, a preferred embodiment of the invention will be described with reference to the accompanying drawings.
-
FIG. 1 is a schematic diagram showing a configuration of a fuel reforming apparatus according to an embodiment of the invention. Afuel reforming apparatus 1 shown inFIG. 1 can reform a mixture of air and hydrocarbon fuel such as gasoline. For example, thefuel reforming apparatus 1 is used for generating fuel (reformate gas) for an internal combustion engine that is a driving source of an automobile. As shown inFIG. 1 , thefuel reforming apparatus 1 includes amain body 2 that is formed to have a generally cylindrical shape, and an injector (fuel supply means) 3 connected to an end portion of the main body 2 (an end portion on the right side inFIG. 1 ). - The
injector 3 is connected to a fuel tank (not shown) via a fuel supply pipe L1 and a fuel pump (not shown). When thefuel reforming apparatus 1 is used, theinjector 3 injects hydrocarbon fuel such as gasoline. As shown inFIG. 2 , theinjector 3 is housed in aninjector housing portion 4 that is connected to themain body 2 of thefuel reforming apparatus 1. In theinjector housing portion 4, anannular air chamber 40 is formed so as to surround afuel injection hole 3 a of theinjector 3. An end of an air supply pipe L2 including an air pump AP and a flow amount adjusting valve FCV is connected to theinjector housing portion 4 such that the air supply pipe L2 communicates with theair chamber 40. When thefuel reforming apparatus 1 is applied to an internal combustion engine, an exhaust gas recirculation pipe may be connected to the air supply pipe L2 (at a portion downstream of the flow amount adjusting valve FCV) in order to introduce exhaust gas of the internal combustion engine to thefuel reforming apparatus 1, as shown inFIG. 1 . The exhaust gas recirculation pipe is connected to an exhaust pipe of the internal combustion engine. Also, only the exhaust gas may be introduced into theair chamber 40 without introducing air (outside air) into theair chamber 40 via the air supply pipe L2. - A
nozzle member 5 is connected to an end of theinjector 3. Thenozzle member 5 includes an air-fuel mixing chamber 50 which is provided in a center of thenozzle member 5 so as to extend in an axial direction. The air-fuel mixing chamber 50 is a space having a small capacity and having a circular cross section. The air-fuel mixing chamber 50 has an inner diameter that is smaller than an inner diameter of the main body 2 (for example, the air-fuel mixing chamber 50 has the inner diameter that is approximately 5 to 15% of the inner diameter of the main body 2). The air-fuel mixing chamber 50 communicates with thefuel injection hole 3 a of theinjector 3, and the inside of themain body 2 of thefuel reforming apparatus 1. Further, pluralair injection holes 51 which allow the air-fuel mixing chamber 50 and theaforementioned air chamber 40 to communicate with each other are provided in thenozzle member 5. O-rings for preventing the fuel or air from leaking to the outside are provided between theinjector housing portion 4 and theinjector 3, and between theinjector housing portion 4 and thenozzle member 5. - In the embodiment, each of the
air injection holes 51 is formed so as to extend from an outer periphery of the air-fuel mixing chamber 50 to a center of the air-fuel mixing chamber 50, and to be displaced from the center by a predetermined length in a predetermined direction. With the configuration, the air flowing from theair chamber 40 to the air-fuel mixing chamber 50 (and the mixture) are swirled around an axis of thenozzle member 5 in the air-fuel mixing chamber 50. That is, each of theair injection holes 51 of thenozzle member 5 introduces air to a portion around thefuel injection hole 3 a of theinjector 3. In addition, each of theair injection holes 51 functions as swirl flow generating means for generating a swirl flow of the mixture in the air-fuel mixing chamber 50. Also, theair injection hole 51 may be formed so as to have the shape of spiral starting from the center of the air-fuel mixing chamber 50. In this case as well, theair injection hole 51 functions as the swirl flow generating means for generating a swirl flow in the air-fuel mixing chamber 50. Also, theair injection holes 51 may be formed so as to radiate in a radial direction in thenozzle member 5. In this case, theair injection holes 51 do not function as the swirl flow generating means for generating a swirl flow in the air-fuel mixing chamber 50. - Meanwhile, in the
main body 2, a reformingreaction chamber 7 including a predetermined reforming catalyst is provided at a predetermined interval from theinjector housing portion 4. Amixture flow chamber 6 that communicates with the air-fuel mixing chamber 50 is formed between theinjector housing portion 4 and thereforming reaction chamber 7. The capacity of themixture flow chamber 6 is larger than the capacity of the air-fuel mixing chamber 50 of thenozzle member 5. The total length of the mixture flow chamber 6 (i.e., the length of themixture flow chamber 6 in the axial direction of the main body 2) is set considering the capacity of the air-fuel mixing chamber 50, the cross sectional area of an outlet of the air-fuel mixing chamber 50, and further a range in which the fuel is sprayed by theinjector 3. In the embodiment, aninner wall surface 6 a of themixture flow chamber 6 is formed to be a curved surface such that the inner diameter of themixture flow chamber 6 gradually increases from the air-fuel mixing chamber 50 to the reformingreaction chamber 7, and the outlet of the air-fuel mixing chamber 50 is smoothly continuous with an inlet of the reformingreaction chamber 7, as shown inFIG. 2 . - Also, in the embodiment, the reforming
reaction chamber 7 is configured by disposing honeycomb body supporting a predetermined reforming catalyst in themain body 2. In the embodiment, the honeycomb body has an outer diameter that is substantially equal to the inner diameter of themain body 2. With the configuration, the cross sectional are of the inlet of the reformingreaction chamber 7 is larger than the cross sectional area of the outlet of the air-fuel mixing chamber 50 of thenozzle member 5. As the reforming catalyst included in the reformingreaction chamber 7, for example, a catalyst in which rhodium is supported by zirconia is employed. Further, a reformategas supply chamber 8 is formed downstream of the reformingreaction chamber 7 of themain body 2. A reformate gas supply pipe L3 (refer toFIG. 1 ) for supplying reformate gas to a target component such as an internal combustion engine is connected to the reformategas supply chamber 8. - The
fuel reforming apparatus 1 includes an electronic control unit (hereinafter, referred to as “ECU”) 10 that functions as control means for thefuel reforming apparatus 1, as shown inFIG. 1 . TheECU 10 includes a CPU, ROM, RAM, an input/output port, a storage device, and the like (none of them are shown in the figure). Theinjector 3, the air pump AP, and the flow amount adjusting valve FCV, various sensors, and the like are connected to the input/output port of theECU 10. TheEUC 10 controls theinjector 3, the air pump AP, the flow amount adjusting valve FCV, and the like based on detection values of the various sensors according to various control programs, maps, and the like. - When the mixture of fuel and air is reformed using the
fuel reforming apparatus 1 thus configured, theECU 10 of thefuel reforming apparatus 1 controls at least one of theinjector 3, the air pump AP, and the flow amount adjusting valve FCV such that the air-fuel ratio of the mixture supplied to the reformingreaction chamber 7 becomes a desired value based on the signals from the various sensors according to a predetermined map or the like. In the embodiment, the desired value is a generally constant value. For example, a ratio O/C between the number of carbon atoms in the fuel supplied to the air-fuel mixing chamber 50 and the number of oxygen atoms in the air supplied to the air-fuel mixing chamber 50 is set to be in a range of approximately 0.8 to 1.05). Thus, theinjector 3 injects the fuel into the air-fuel mixing chamber 50. Also, the air supply pipe L2 supplies air into theair chamber 40 in theinjector housing portion 4. The air that has flown into theair chamber 40 is injected from each of the air injection holes 51 of thenozzle member 5 into the air-fuel mixing chamber 50 such that the air collides with the fuel injected from theinjector 3. Further, a swirl flow is generated due to the air (and the mixture) in the air-fuel mixing chamber 50. - Thus, in the
fuel reforming apparatus 1, the fuel and the air are supplied to the air-fuel mixing chamber 50 in such a manner that the fuel and the air are mixed with each other. The air-fuel mixing chamber 50 has the outlet whose cross sectional area is smaller than the cross sectional area of the inlet of the reformingreaction chamber 7, and has the capacity smaller than the capacity of themixture flow chamber 6. With the configuration, the fuel is atomized efficiently in the air-fuel mixing chamber 50 in which the flow rate is increased, and the fuel reliably contacts the air in the air-fuel mixing chamber 50 which is a small space. Accordingly, in thefuel reforming apparatus 1, the fuel and the air can be mixed with each other uniformly. Thus, it is possible to allow the reforming reaction in the reformingreaction chamber 7 to proceed efficiently, and to obtain high reforming efficiency (high fuel conversion rate). Also, in thefuel reforming apparatus 1, since the swirl flow is generated in the air-fuel mixing chamber 50 due to the air flowing into the air-fuel mixing chamber 50 from each of the air injection holes 51 (and the mixture) as described above, the fuel and the air are mixed with each other in the air-fuel mixing chamber 50 more uniformly. - The mixture of fuel and air, which is obtained by mixing the fuel and the air uniformly in the air-
fuel mixing chamber 50, flows into themixture flow chamber 6 from the air-fuel mixing chamber 50. Since theinner wall surface 6 a of themixture flow chamber 6 is formed such that the outlet of the air-fuel mixing chamber 50 is smoothly continuous with the inlet of the reformingreaction chamber 7, the mixture obtained by mixing the fuel and the air uniformly in the air-fuel mixing chamber 50 flows into themixture flow chamber 6 from the air-fuel mixing chamber 50, and flows in themixture flow chamber 6 while being diffused along theinner wall surface 6 a of themixture flow chamber 6. Then, the mixture flows into the reformingreaction chamber 7 from themixture flow chamber 6. As a result, in thefuel reforming apparatus 1, it is possible to reliably prevent the concentration of the mixture in themixture flow chamber 6 from becoming non-uniform. - Subsequently, in the reforming
reaction chamber 7, the hydrocarbon fuel and the air are caused to react with each other by the reforming catalyst. For example, a partial oxidation reaction that is represented by the following formula (1) proceeds, whereby the reformate gas containing CO and H2 is generated. The obtained reformate gas flows into the reformategas supply chamber 8 from the reformingreaction chamber 7. Then, the reformate gas is supplied to the target component such as the internal combustion engine from the reformategas supply chamber 8.
CmHn+(m/2)O2→mCO+(n/2)H2 (1) - In the embodiment, supply of air to the air-
fuel mixing chamber 50 via the air supply pipe L2, and injection of fuel into the air-fuel mixing chamber 50 by theinjector 3 are controlled by theECU 10 separately. With the configuration, the air-fuel ratio of the mixture supplied to the reformingreaction chamber 7 can be set freely according to an operating condition of an internal combustion engine to which thefuel reforming apparatus 1 is applied, a state of the reforming catalyst in the reformingreaction chamber 7, and the like. Also, when thefuel reforming apparatus 1 is applied to an internal combustion engine, air can be inhaled into the air-fuel mixing chamber 50 using vacuum pressure in the combustion chamber of the internal combustion engine. Therefore, in this case, the air pump AP may be omitted. - Further, in order to start the reforming reaction in the reforming
reaction chamber 7, it is necessary to make the temperature of the reforming reaction chamber 7 (reforming catalyst) equal to or higher than a predetermined temperature (for example, approximately 400° C.), in addition to supplying the mixture appropriately. In order to make the temperature of the reformingreaction chamber 7 equal to or higher than the predetermined temperature, it is preferable to preheat the reforming catalyst before the reforming reaction is started, by employing a method using a known electrically heated catalyst (not shown) (a method in which electricity is supplied to a so-called metal honeycomb body that is a carrier for supporting the reforming catalyst, which is composed of a metal thin film so as to heat the honeycomb body), a burner type heating method (a method in which a burner is disposed upstream of the reforming catalyst, and the reforming catalyst is heated using heat generated by the burner), or the like. Once the reforming reaction is started, the reforming reaction continues due to heat generated by the reforming reaction. Therefore, supply of electricity to the honeycomb body or heating by the burner may be stopped. -
FIG. 4 is a partial cross sectional view showing a fuel reforming apparatus according to another embodiment of the invention. Afuel reforming apparatus 1A shown inFIG. 4 includes a reformingreaction chamber 7A including a reforming catalyst (for example, a catalyst in which rhodium is supported by zirconia). In the reformingreaction chamber 7A, steam reforming is performed using hydrocarbon fuel such as methanol, air, and water so as to obtain predetermined fuel gas. In this case, thefuel reforming apparatus 1A includes afuel injector 3F, and awater injector 3W. Each of thefuel injector 3F and thewater injector 3W injects fuel or water into an air-fuel mixing chamber 50A that is a small space formed in aninjector housing portion 4A. The air-fuel mixing chamber 50A has an outlet whose cross sectional area is smaller than the cross sectional area of an inlet of the reformingreaction chamber 7A. Also, in theinjector housing portion 4A, anair chamber 40A is formed so as to surround a fluid injection hole of thefuel injector 3F and a fluid injection hole of thewater injector 3W. Theair chamber 40A communicates with the air-fuel mixing chamber 50A via plural air injection holes 51A. - In the
fuel reforming apparatus 1A thus configured as well, the fuel and water are atomized efficiently in the air-fuel mixing chamber 50A in which the flow rate is increased, and the fuel reliably contacts the air in the air-fuel mixing chamber 50A. Accordingly, in thefuel reforming apparatus 1A as well, the fuel, water, and air can be mixed with each other uniformly. Thus, it is possible to allow the reforming reaction in the reformingreaction chamber 7A to proceed efficiently, and to obtain high reforming efficiency. That is, the invention can be applied to a fuel reforming apparatus that includes plural fluid injection means including at least a fuel injection valve.
